2. Hach Hardness Tests Strips

Hach Hardness Tests Strips

One of the most common contaminants in tap water is calcium. Calcium build in water can coat your pipes which can cause problems with your plumbing and give your water a funky taste. Hack Hardness Test Strips are designed specifically to test for calcium deposits in your water and let you know if they are above a safe amount. One of the better features of these strips is how affordable they are. A single set costs just under $1 and contains 50 strips, good for 50 individual tests.

Hardness in water is usually caused by magnesium and calcium ions to those are the ones that the Hach strips test for. While other minerals can cause water hardness, these are usually not in large enough quantities to detect in potable water you’d find from the tap. The strips test for ion concentrations and turn a specific color depending on the concentrations; green for lower concentration sup to orange for high concentrations.

The only downside of the Hach is how limited they are. They only test for water hardness so they can’t be used to check alkalinity, pH, nitrate, or bacteria. Otherwise, they do what they are designed to do just fine. All strips are tested for accuracy and it has several positive user reviews that claim it is easy to use and accurate. The only downside is that it can sometimes be difficult to read the colors, especially when the strip is on the edge between two colors marked on the bottle.

What We Like:

  • Easy to use and simple
  • Accurate
  • Affordable
  • Simple and straightforward to read
  • Only requires strips, nothing else

What We Didn’t Like:

  • Can sometimes be hard to distinguish different colors
  • Strips only last 2 years
  • Only tests for hardness

3. Health Metric Heavy Metal Water Tester Kit

Health Metric Heavy Metal Water Tester Kit

Heavy metals are one of the most dangerous water contaminants. Heavy metal poisoning manifests several symptoms and is slow-acting, so it can be extremely hard to catch if you do not know what you are looking for. The Health Metric Home Water Testing Kit is designed specifically to test for concentrations of heavy metals in your water, such as iron, lead, mercury, and copper. The simple-to-use testing kit takes about 15 minutes to get results and does not require any extra equipment. All components are made in the USA and tested to ensure accuracy and precision. Further, all testing benchmarks meet standards set by the EPA.

Testing water is easy. Just collect a sample in the included vial, choose the appropriate testing strip, and place it in the water sample. The strips can detect even low-level concentrations of heavy metals and change color to immediately identify you which metals are in your water. The strips are designed by a tea that has over 30 years of experience in the water testing industry so you know they are high-quality.

The one downside is the lack of other tests. These strips only test for heavy metals, and not for bacteria, alkalines, pH, or nitrates. It also only comes with 1 lead test, which is strange considering that lead is one of the more dangerous kinds of heavy metals. Otherwise, the strips are easy to use, accurate, and affordable. Make sure you buy from a legitimate vendor too, as some people report getting fakes or incomplete packages.

What We Like:

  • Tests for 4 heavy metals
  • Simple to use and can be done at home
  • Accurate for low to med concentrations

All tests are made to match EPA standards and the entire package is very affordable. Individual tests take around 10 minutes to complete and do not require any extra equipment.

Having a test designed specifically for well water is nice as things can leach into your well water system without your knowledge.

5. HM Digital Water Testing Device

HM Digital Water Testing Device

Up next is this unique digital water testing device from HM. The best part of the HM is that you no longer have to deal with strips. It has a built-in thermometer, an LED display, and an advanced microprocessor that determines the composition of your water by measuring the resistance of a small electric current. Just take a small sample of your water, insert the tooltip and you can read the results directly on the LED screen. It also comes with a belt clip and carrying case.

The HM measures the amount of salt, metals, and minerals in the water to within a 2% range of accuracy. It can be used to test drinking water, pools, aquariums, and more. Unfortunately, it only tests for general PPM measurements and cannot give you specific data on the water composition. This means you will have to look up elsewhere whether your water meets certain standards for safety. It does, however, have a useful built-in thermometer so you can check water temperature while testing its composition.

Although the HM is a useful water testing device that does not require strips, it is not the best quality tool out there. This is somewhat to be expected considering how inexpensive it is, but it may be a problem if you need to make very precise water measurements. On the scale it is designed for, it’s very accurate though.

What We Like:

  • The digital device requires no strips
  • Microprocessor takes measurements
  • Built-in thermometer
  • Easy to read display

What We Didn’t Like:

  • Not incredibly accurate
  • Quality control seems hit or miss

6. Baldwin Meadows 10-In-1 Water Test Kit

Baldwin Meadows 10-In-1 Water Test Kit

Sitting at sixth is this water testing kit from Baldwin Meadows. The Baldwin Meadows kit tests for 10 different water contaminants including hardness, copper, chlorine, pH, alkalinity, lead, iron, nitrates, nitrites, and bacteria. This reliable test is easy to perform. Just gather a sample of water in the testing vial, choose the correct strip, and the test will be completed in just under 10 minutes. Like most commercial water testing kits, the benchmark levels are set to EPA health standards for water quality.

A single canister holds over 100 strips so you can perform over 100 different tests before you have to buy more. Each test is sensitive and measures to within 5 ppm, well within error levels for water testing kits. It is specially designed to detect low levels of heavy metals and fluoride as those compounds can be hard to detect with water testing kits. Baldwin Meadows also offers a souped-up water testing kit that comes with 14 different tests which includes stirps for mercury lead, and sulfates.

The Baldwin Meadows is probably most effective for testing water hardness levels, and some reviewers note that it has problems with the copper and lead tests, which is a shame because those are two important heavy metals to check for. Unfortunately, the quality control seems hit or miss as many reviewers report that their kits came missing some strips or just straight up do not work. In the cases where the kit works, user reviews are very positive.

What We Like:

  • 10 different tests
  • 100 strips per bottle
  • Very affordable
  • Test for most major pollutants
  • Designed for city water use
  • Tests for fluoride as well

What We Didn’t Like:

  • Lead and copper tests are a bit shaky
  • Quality control seems hit or miss
  • Poor customer suppor
