home water test kit Buyer’s Guide

If you keep the before points in mind, you can easily go out to the market and buy home water test kit, right? No!

Packed Tower Aerator

This makes use of a tower that can go up to ten feet in height, filled with packing material up to inches in size. This material can either be pieces of ceramic or plastic. Water falls from the top of the tower, and air is blown in from the bottom of the tower opposite to the water flow, transferring the contaminants to the air by making it rise to the top of the tower, which will then lead to it being vented out of the home.One factor to consider in purchasing a packed tower aerator is that finer pieces of packing material will result in more efficient contaminant removal, but will increase electricity costs because of the air pumping.

Some consultants are increasingly recommending the use of ultraviolet germicidal irradiation for water filtration systems even in ordinary homes. Commonly used in medical sanitation, UV lamps purify water without the use of chemicals by killing microbes. They are comparatively lower in cost. Maintenance only requires changing the filter cartridge that comes with it from time to time, as well as the annual replacement of the lamp.

Some people choose to use this instead to avoid contaminating their immediate surroundings with chlorine, which is being increasingly regulated by environmental protection agencies everywhere as a waste product. It also does not make the water smell or taste foul, unlike chlorine or using other chemicals to purify water.

An ultraviolet lamp is an option even in point-of-use systems, as you can readily source a lamp specifically for the use of a drinking tap, making it a more feasible solution for those who need to purify their well water on a tight budget. Attaching it to a point-of-use system also allows you to easily regulate the flow of water from the source to the exit point, which will allow you to avoid the con below.

The con to using only a UV lamp is that the well water needs to be strictly regulated. If the flow rate is too high, the water will pass through the lamp without sufficient exposure to UV rays to kill microbes. However, if the flow rate is too low, heat may build up on the system and damage the UV lamp.

Suggested Set-Up For Well Water Filtration At Home

Yes, perhaps you may think that point-of-use systems are ultimately less fiddly and require less planning to execute in the home—and they usually are, if you’re sourcing water from a tap in an urban area or from a municipal source. But if you’re getting your water from a well, it will save you trouble in the long run to choose whole house filters for well water and deal with only one point of entry to enjoy clean water throughout the entire home.

Based on whole house well water filter systems reviews on ecologist James McMahon’s website, it really may be better to opt for either of the template systems above if you have a high percentage of dissolved solids in your water source. Reverse osmosis in particular is highly recommended as saltwater contamination is a very real problem in coastal areas.

A possible downside of choosing to go with any system that integrates these filters is that because a reverse osmosis process relies on increased pressure, your electricity bill may go up.

Worth the Trouble

All of this is a small price to pay compared to the frustration you’ll face from removing bacteria, unwanted mineral deposits and dangerous substances from hard water or going to the hospital because you drank unsafe water.

Whatever system you choose to integrate in your home, proper storage of the filtered, decontaminated water is necessary, as once the chlorinated water has been degassed or the water is no longer exposed to ultraviolet rays, recontamination is possible if it is not placed in a sanitary environment.

Our User Rating

Ammonia is the number one killer of tropical fish in aquariums, produced from fish waste and uneaten fish food. The API Ammonia Test Kit is a liquid test for freshwater and saltwater aquariums, testing ammonia levels ranging from 0 to 8ppm. The kit also contains a color chart, a glass tube and clear instructions.

Pool Test Strips

The most inexpensive and widely used method of water testing – test strips – is fast, easy, and fairly accurate. Water testing strips like the AquaChek Test Strips can be used to test for individual chemicals or you can buy something like AquaChek Select Way Test Strips or YellowYellow Way chlorine test strips to make multiple tests at the same time.

The most amazing feature of test strips other than their low price is that they are very simple to use; just dip them in water, swirl and read the results within seconds. Usually the test strips are color coded and come with an easy-to-read chart that lets you easily determine which chemicals you need to add to your pool.

Liquid Test Kits

Liquid test kits are an excellent way to determine chemical levels in your pool and maintain crystal clear water at all times. Obviously higher in price as compared to testing strips, the liquid kits offer a more reliable and complete testing solution. Liquid testing kits like the LaMotte ColorQ Pro Water Chemistry Liquid Test Kit make use of reagents that are added to sample water and results are read on a user-friendly comparator.

Liquid testing kits like the 4-Way Test Kit Liquid Solution are economical and easy to use, and some like the Taylor Basic Residential DPD Test Kit take maintenance a step further and include a dosage chart for translating test results into treatment.

Digital Pool Testers

What is the first thing that comes to mind when you hear the word digital – accurate and fast, right? Well when it comes to digital water testers, accuracy and promptness is what these amazing testers offer. Extremely easy to use, the digital water testers often feature LCD display, water-resistant housing, memory function, and no color matching, so reading results is a snap.

Digital pool testers have electrodes that measure chemical levels in the water with results that have more accuracy and dependability. Of course more on the expensive side, Digital water testers are definitely my favorite for a reliable, complete and fast water testing solution.

As a pool owner, you know that pool maintenance is not easy and does not come at a flip of a button. Regular pool testing is an important foundation to prevent other pool problems. These water testing solutions mentioned above are perfect to keep water balance easy and make your overall pool maintenance a little lighter.

Liquid tests

These are probably the most well known and are based on the colour change of the indicator caused by the level of hydrogen ion concentration of the water. The resulting colour is then compared to a standard colour chart corresponding to a known pH. Some of the drop tests can measure a broad pH range (e.g. 3–or 4–10), but I found them quite inaccurate in acidic conditions. You could get better results with tests in the range 6–7.or 7.4–9.

Dip tests

These can give you a quick, albeit often less accurate result. Just dip the test strip in the water and match the colour on the reference chart or use your camera phone to take the readings for you. The test strips are sensitive to high humidity and can age quickly, so always keep the tub closed.

Electronic tests

Using a handheld or built-in electronic pH meters eliminates the use of indicators and also gives you an option to quickly check the pH in several tanks or monitor it in a permanent way. The most frequently used probes have a glass electrode and a reference electrode. They determine the pH of the water by measuring the voltage (potential) between them. The results strongly depend on the sensitivity and the quality of the probe, so it’s worth investing a bit more in a reliable meter to ensure you have accurate results. Some will even control and maintain the pre-set pH for you. Another issue that can have a strong influence on accuracy is calibration. Electronic pH probes must be calibrated regularly. The cheaper versions use only a one-point calibration (at pH7), but the better ones have two- or three-point (at pH4, pHand pH10) calibration. Check the manual as to whether your probe requires dry or wet storage, as the dried out electrode will deliver false results.

The Pro-Lab Water Testing Kit Controversy

Young initially turned to Pro-Lab’s lead testing kit, which she discovered while browsing her local Home Depot.

Immediately concerned over the nature of this certification and how it might apply to water tests, Young attempted over the course of two days to get in touch with Pro-Lab representatives. Eventually, Pro-Lab Chief Executive James McDonell contacted Young, and admitted that the International Associations of Certified Indoor Air Consultants “doesn’t have expertise in water testing”, and instead works with home inspectors. (Although per their website, lead issues do fall under their general purview.) McDonell asserted that they endorse all of Pro-Lab’s test kits.

Through spokesmen Stephen Holmes and Kylie Mason, both Home Depot and the Florida Attorney General’s Office, respectively, have informed Young they are investigating the claims put forth by Pro-Lab and their Lead In Water Test Kit regarding the kit’s efficacy and certifications.


Silver Lake’s spokesperson told Young and USA TODAY that no government agency certifies or verifies these types of home lead test kits. As the vials are never sent off for testing, there is no outside lab involved that carries any certifications, either.

Tube can be difficult to fill properly

We rated the pH Soil Meter, 3-in-Soil Tester Kit 5.0 out of stars, and is an excellent moisture meter, light, and pH acidity tester. Its responsive probe senses soil changes and displays accurate values to the user. No electricity or batteries are used by this product, making it environmentally friendly. Moisture is measured by inserting the probe completely into the soil to reach the root level. The correct moisture level will be displayed, and the user simply needs to refer to the included chart to find out watering needs.

Light is measured by holding the meter next to a plant and facing a light source (don’t touch the sensing element which is located underneath the gauge!). Check light level and refer to the included chart for correct light requirements. To test soil pH, insert the probe into the soil. A pH reading that’s less than is acidic, and readings greater than indicate an alkaline soil.

This quality dual soil pH and moisture meter is rated 4.out of stars (by us), and provides simple, accurate checking of soil moisture level and pH balance (alkalinity and acidity). Its extra long probe allows users to measure significantly below a plant’s root zone. This meter is perfect for commercial use (orchards, vineyards, lawn maintenance, and field production) and home use (planters, lawn maintenance, and gardens).

This product includes moisture and soil pH meter and instruction manual. It works as advertised, gives accurate pH level readings, and is good for either commercial or home use.

This 4-in-instrument is a light and temperature sensor (measures sunlight intensity and temperature using an in. (200mm) probe), and also tests moisture and pH balance. Readings are clearly displayed on a large LCD screen. This product also features an automatic power-off function and a low battery indicator.

Testing for Arsenic

In the past, testing for arsenic in drinking water has been as difficult as removing it. Measuring arsenic concentrations accurately was left to the laboratory and expensive instrumentation such as atomic absorption spectrometers. Time delay and expense are the obvious problems with this approach. A variety of test kits have appeared on the market deriving from the need for easier, cheaper and faster methods. These test kits rival both the accuracy and low detection ability of laboratory instrumentation.

Of the available competing products, the most useful arsenic test kits report quantitatively as well as qualitatively.

All of these kits rely on similar chemistry in which inorganic arsenic compounds (As+and As+5) are reduced to arsine gas. This is done in a controlled reaction between an acidified water sample and zinc powder. A volume-specific reaction vessel, usually a plastic bottle supplied in the test kit, is used for this reaction. Different kits typically require different sample sizes and usually employ additional reagents to control interferences from other common elements found in groundwater such as hydrogen sulfide and iron. Once the sample and all of the reagents are combined in the reaction vessel, a test strip is used to measure the arsenic concentration of the water sample. The test strip is not dipped into the sample but rather placed above the sample in a special cap that seals the reaction vessel. As the arsenic converts to arsine gas and comes in contact with the test strip, the mercuric bromide indicator on the test strip changes in color from white to shades of yellow and brown. This chemical reaction varies in time between test kits from to 30 minutes. Once the reaction is completed, the test strip is removed and matched to a color comparator chart to obtain a quantitative measure for arsenic in the tested sample.

Correlation Study

When considering options in arsenic testing, people often ask if a test strip-based test kit really is an accurate way to measure arsenic. Answering “yes” in a positive tone does answer the question. Actual test data from a third party is more convincing proof and often is requested. To help in demonstrating arsenic field test kit accuracy, a non-biased third party was used to conduct a study of the major brands of arsenic test kits available in the United States.

In reviewing the results from the chart, it is important to remember that the test kits studied use test strips. Test strips are colorimetric and the results depend on matching colors by eye. One shortcoming of a colorimetric test like this is the limited number of preselected levels present on a color chart. This limited number of levels, which convert to test results, sometimes requires the reader to estimate a reading that is between available colors. For example, of the four test kits studied only one had color levels available on the color chart below ppb. Yet, the individual running these tests was still able to estimate results of ppb. In another instance, with the Low Range Arsenic Check, there was no 50 ppb level (only 40 and 60 ppb), but an accurate result was estimated. In summary, a strong point of this type of arsenic test kit is test result resolution. Between the mercuric bromide indicator on the test strip and carefully printed color charts, the individual running the test is able to obtain a detailed picture of arsenic concentrations in water—even with only a test strip.

A second point to make with reference to the test data is the obvious reproducibility of these test kits from one test to the next. At each level of arsenic concentration, two samples were tested. When the tests for each kit were completed, results were found to be the same for both samples of the same arsenic concentration. Predictable and reproducible results are as important as accurate results when considering test methods.

Important Test Kit Features

Although most arsenic test kits use the same basic method and chemistry, each kit is unique. When considering which test kit you will choose, there are some important factors to consider.

Ease of use. A variety of kits is available with varying levels of complexity. Testing for arsenic may not be as easy as testing for many other ions. However, some manufacturers have done a better job than others at making test procedures easy to perform and understand. Fewer steps, easy-to-read instructions and illustrations are key to reducing confusion and human error.

Time. Three of the four test kits included in the study require a 30-minute incubation time while the arsenic in the water sample is reduced to arsine gas. Compared to other test methods, 30 minutes is a great time saving. However, if you have a large number of samples to test, or just don’t like to wait, a 10-minute test may be more desirable. The addition of arsine gas enhancers in a kit’s reagents runs tests in a third of the time of other kits.

Sensitivity. Detection range or sensitivity is a common question regarding arsenic testing methods. With the current arsenic standard of 50 ppb in debate and most water sources in the United States below 100 ppb, additional sensitivity eventually may win out over other test kit benefits. At the same time, water quality professionals who install arsenic remediation devices ask for tests that detect less than ppb. This low detection sensitivity is important for the calibration and efficiency confirmation of the arsenic removal equipment. With these considerations, a low-range arsenic kit may be your best option with low detection levels at 2, 4, 6, 10, 15, 20 and up to 240 ppb. This is accomplished by a larger sample size (250 ml compared to 50 or 100 ml) and chemical enhancers that produce colors of greater intensity at lower concentrations of arsenic.

Which type of test method is right for your arsenic detection and measurement needs? Improvements in test strip technology make it possible to test water for arsenic easily, quickly, cost effectively, accurately and at useful detection levels. Using the previously stated considerations ease of use, testing time, cost and sensitivity, your arsenic test kit should be easy to select.

Get advice from a health professional first

It’s important to remember that, if you are taking any medicines, they may affect your test results. It’s worth getting advice from a health professional first, as using a self-test kit may not be appropriate for you.

It’s rare for a self-test kit to give a 100% guarantee that you have or don’t have a particular condition. It may not be as helpful as having a consultation with a GP or other health professional.

Before using a self-test kit, make sure it has a CE quality assurance mark. This means that, provided you use it correctly, the kit will work properly and is safe.

If you have any concerns, speak to a healthcare professional, such as a pharmacist, practice nurse or GP.

When you get your results

No self-test kit is 100% reliable, and a CE mark is still no guarantee that a particular home test is suitable for you.

If you have any concerns about your results after using a self-help kit, make sure you get advice from a health professional.

If you do a self-test for HIV and the result is positive, it’s important that you contact a health professional as soon as possible and get the emotional and medical support you need.

Self-test kits for STIs

Everyone can get free tests for any STI, including HIV, from their GP or local sexual health clinic.

Self-test kits for STIs are also available online and on the high street. They include home testing kits for infections such as chlamydia and gonorrhoea that you can send away to a laboratory.

If you think you may have an STI the most important thing is to get tested and get medical advice quickly so that you can start treatment.

Some pharmacies provide an STI testing service (including those for chlamydia) and some can provide the treatment.

Free HIV tests if you’re at higher risk 

Free self-sampling HIV test kits are available online in many areas of the UK to people who are at higher risk. To check whether you are eligible, or to find your local HIV service, go to test.hiv.

HIV self-test kits are also available from some pharmacies, but you will usually have to pay. It is important to check that any test you buy has a CE quality assurance mark and is licensed for sale in the UK, as poor-quality HIV self-test kits are still available from overseas.

You may need emotional support and counselling if you are testing for HIV, particularly if the result is positive.

Self-test kits for cancer

You can buy cancer-related self-test kits from your local pharmacy, including tests for prostate cancer and bowel cancer.

However, if you are worried or think you have the symptoms of cancer, it’s best to get advice from your doctor straight away. They will be able to refer you on to a hospital specialist if necessary.

Testing for bacteria in water

A home testing kit is very convenient way of determining water quality quickly with approximate values that are close to what you will obtain if the water was sent to a water testing laboratory.

Testing for bacteria in water is easy, because there is what are called ‘dipslide’ or ‘dip slide’ or ‘petridish water test kits’ for testing for bacteria in water. The dipslide and petridish tests for bacteria will give fairly accurate results. These dipslides or petridishes for testing for bacteria in water will have to incubated or be kept for a few days in a warm spot to see the bacteria grow and from the color and size of the bacterial colonies in the petridish or on the dipslide we can know if there is bacterial contamination of the water.

Min Read

Before water gets into your home, it has to be filtered and treated with chlorine to remove dirt, bacteria, and all other possible contaminants. But as doctors advice, too much chlorine and regular exposure to this chemical can be risky to human health.

It’s almost impossible to approach the water company and to be sure you have gotten truthful answers on the water’s chlorine levels.

Our main takeaway from testing was the confidence that NSF certification is a broadly reliable measure of a filter’s performance.

So we went looking for other options that we hadn’t tested before. In March 2017, Brita unveiled the Longlast Filter. Rated to 120 gallons or six months, three times the 40 gallons or two months of most pitcher filters, it immediately caught our eye. Its price (over the course of a year of use) was comparable to that of the standard filter. And it was certified by the Water Quality Association to NSF standards for chlorine, lead, cadmium, and some other contaminants. Given the lifespan, price, and certifications, as well as our 201observations of its competitors, there was no real chance that another filter could rival this option as long as it proved decent to use over time.

We called in a pair of Longlast filters and two compatible Brita pitchers, an Everyday and a Grand, and ran them through an extended real-world test. We evaluated the pitchers on their practical qualities: ease of use and cleaning, plus comfort in handling. And we monitored the filters to measure Brita’s stated claim of 120-gallon/six-month performance. Longevity in the lab is one thing—surviving in a 50-year-old New York City apartment with rusty pipes is another.

Flaws but not dealbreakers

It’s puzzling, and a bit frustrating, that Brita does not yet bundle the Longlast Filter with a pitcher as part of a package deal—you have to buy them separately. In addition, the upper reservoir of the Everyday Pitcher (and the Grand, for that matter) is unreasonably difficult to remove, which you need to do occasionally in order to clean the lower reservoir. You have to run your finger or thumb down the spout, grip very hard, and jiggle the reservoir while pulling up. There has to be a better way.

Most owner reviews of the Longlast are strongly positive, regarding both its functionality and the taste of the water it produces. However, two complaints show up with some regularity: that the Longlast doesn’t seat properly in the pitcher, allowing unfiltered water to leak into the lower reservoir, and that the filter quickly clogs and stops filtering. We haven’t experienced either problem, but like anything, the Longlast isn’t flawless.

The competition

In a previous iteration of this guide, we chose the Pur Classic 11-Cup Pitcher (aka Pur LED) as the best water filter pitcher for most people. NSF International certified its filter to significantly reduce 10 contaminants from the water poured into it, including several heavy metals and biocides. In our test, the Pur filter performed better than or nearly as well as every other filter we considered in every category we thought was important, and it had no obvious flaws.

We also recommended the Mavea Elemaris XL in 2016, as a slightly more ergonomic pitcher that performed about as well as the Pur Classic in our filtration tests. However, Mavea has since pulled out of North America, so we can no longer recommend its items. If you already own an Elemaris, be aware that no replacement filters will be available after the remaining inventory is sold.

In 201we tested the standard Brita filter (which comes with the Brita Everyday Pitcher we recommend). The standard filter left behind a significant amount of chlorine, earning a low score on water taste. And it is NSF 5certified for only three contaminants (mercury, copper, and cadmium), whereas our pick, the Brita Longlast Filter, is certified to remove five (lead, mercury, cadmium, benzene, and asbestos), plus another five emerging contaminants under Standard 40In short: You’ll get a standard filter with your Everyday Pitcher, but it’s best to ignore that one and install a Longlast instead.

Brita makes a wide range of other pitchers, and most of them work with the Longlast Filter. These include the Amalfi, Capri, Chrome, Classic, Marina, Metro, Mini Plus, Monterey, Pacifica, Slim, Soho, Space Saver, Stainless Steel, and Wave. We didn’t test them all; many are smaller than the 10-cup capacity we think is best for most people, and given that they all accept the Longlast, the only other differences are aesthetic. If you own one of these and like it, you have no reason to replace the pitcher—just the filter.

Clear2O made a name for itself with its CWS100AW, a highly regarded filter pitcher (Consumer Reports rated this model near the top of its list). This pitcher is unique in that it uses pressurized water from the faucet, rather than gravity, to force water through the filter. As a result, Clear2O uses a compressed block of activated charcoal rather than loose granules, and that results in truly spectacular NSF 5certifications: 3of them, including for lead, mercury, cadmium, and a host of organic compounds (biocides and petrochemicals for the most part). It also filtered a liter of water in just 1seconds in our test, far and away the fastest result we got. So why don’t we recommend the CWS100AW? Because its faucet system is fussy—it was our least favorite pitcher to use—and involves permanently installing a special nozzle on your faucet and attaching it via a collar coupling to a hose on the pitcher every time you want fresh water. What’s more, the nozzle doesn’t fit on every faucet, and we couldn’t confirm that it fits on any pull-down faucet. Lastly, Clear2O is shifting its focus to a new line of gravity-fed filters, and though the company promises to always keep the CWS100AW (or something similar) on the roster, that’s a bit unnerving.

We also tested the new Clear2O gravity-fed pitcher, the GRP200. This model is NSF 4certified for removal of chlorine taste and odor but not yet NSF 5certified for any contaminant. It’s generally easy to use, but not spectacular or terrible in any aspect.

The Soma Pitcher is stylish but lacking in substance. Although the Water Quality Association certified it to meet NSF 4for chlorine removal and taste, at the time of our tests it was not NSF 5certified, which all the other filters we tested were. (Update: As of October 2016, the Soma filter is WQA-certified to NSF 5for copper and mercury.) In use we found it tricky to pull apart for cleaning, and the wide spout made for problems when we needed to pour with precision (such as filling a drinking bottle). And despite meeting NSF 4standards, the one-stage charcoal filter did the worst job of removing chlorine of any pitcher filter we tested.

How to find out if your water is safe to drink

Tap water in the US is highly regulated by the Environmental Protection Agency and is generally of extremely high quality. The public water supplies are a critical resource and are carefully monitored, with thousands of tests performed each year for up to 40 or more compounds. Once a year, the public is required to be notified of the testing results via a Consumer Confidence Report. You can often find copies of these reports online via this tool, or see this example CCR (PDF) for a local municipal water supply in San Diego. The CCR details where your water comes from, how it is treated, and its test results. In 2014, for example, San Diego’s water supply was tested 6,77times throughout the distribution system for total coliform and E. coli, with an average of 0.percent of samples testing positive (the range was 0.0 percent to 0.percent). Note that “testing positive” and “being dangerous” are not the same thing.

But even careful EPA testing is not the end of the story, as the Flint water crisis made plain. Water leaves municipal treatment plants in beautiful condition—but that doesn’t mean it arrives at your faucets that way. Lead pipes, leaded pipe solder, leaking water mains—those factors and more can introduce contaminants as water makes its way to and through your home. Quite literally, water quality can change from door to door, sometimes dramatically. So even though part of the CCR protocol involves testing the most at-risk end-user locations, it can’t necessarily tell you the quality of your water.

Details from our 201lab tests

We evaluated each pitcher on two subjective measures—taste and ease of use—and several objective ones, including the speed of filtration, the filter capacity, and, of course, the quality of the filtration itself. Because all our test pitchers had NSF 4certification and most had NSF 5certification, we didn’t retest every single thing they could filter out. Instead, we limited our testing to a few factors we believed would matter most to readers. We focused on the removal of chlorine, which has a big impact on water’s taste and smell, and we looked at the ability to remove “total dissolved solids”—basically, mineral salts and organic matter. For our top two picks of 2016, we added an independent test for lead removal.

We used three water sources for our tests: tap water from the kitchen faucet in a 1960s San Diego ranch house (unfiltered water with the most contaminants) as a positive control, water from a fridge dispenser (in-line filter), and lab-grade reverse-osmosis-purified water (super-clean water) as a negative control.

Prior to testing we washed the pitchers by hand with dish soap, rinsed them, and dried them. While the pitchers were drying, we soaked the filters in cool tap water for 1minutes and then flushed them under cool tap water for seconds. Next, we installed the filters according to the manufacturers’ directions and filled the pitchers with water and discarded the water three times to remove any loose carbon dust. We then used water collected from the fourth fill for the following tests.

For the chlorine test, we tested water samples for temperature with a digital thermometer (roughly 20 degrees Celsius or 6degrees Fahrenheit), then measured chlorine levels by inserting a test strip from Industrial Test Systems and color-matching the results according to the manufacturer’s directions. We also measured the samples’ pH using indicator strips, and found it to be neutral in all cases. We used an HM Digital TDS-EZ meter to measure total dissolved solids at the parts-per-million level (ppm).

Taste and ease of use are subjective measures, of course. Two testers tasted filtered samples from each pitcher two times and ranked them for overall good taste and lack of chlorine odor. We also ranked the pitchers’ usability on factors such as ease of filling and pouring, ease of replacing the filters and lids, and ergonomics.

Jump back.

The Water Quality Association 401-certified the Longlast for use in conjunction with Brita pitchers that are equipped with an electronic refill reminder—and our top-pick pitcher doesn’t have one of those. But refill reminders have no effect on how the Longlast works.

Water testing frequency

Since some elements change slightly slower and others faster, water testing should be done in different frequencies: pH and chlorine are done daily; temperature and alkalinity are done weekly, and calcium hardness and stabilizer levels are tested monthly.

Knowing your pool’s chemical character in different settings and temperatures will help you monitor changes in scheduling water tests on the pool.

Kinds of pool test kits

The demand for pool testing kits has consistently increased in the past years, and various types and brands fill the market.

The pool test kits that you will find as you shop around will fall under any of these basic types.

Wet chemistry kit – this kit is considered as the most advanced method of pool testing. It comes in two forms – OTO (Orthotolidine) and DPD (Diethyl p-phenylenediamine). With this kit you get the exact outcomes using the color comparing block to filter the water from a plastic vial.

OTO kit – compared to the DPD, this kit is less expensive for the reason that it can only test the amount of total chlorine in the pool, and does not distinguish between the amount of free chlorine and combined chlorine. This can pose an issue in figuring out the amount of sanitizer to be used.

DPD kit – this kit is used to measure the amount of free and total chlorine in the swimming pool by extracting a water sample from the pool and adding more than a few drops of reagent into it. There’s a little waiting involved before the results show. This method is more reliable than other testing strips, with more enhanced details and higher accuracy.

This is one of the best kits you can find on the market these days. It can test and also provide immediate results for chlorine, pesticides, lead, bacteria, and hardness. These elements that are usually found in your drinking water system can definitely lead to serious health problems.
