Some of the water testing kits that look for numerous contaminants tend to be quite expensive. They may not be the most sensible purchases if you have a tight budget already.

Test on most common contaminants: It checks for bacteria, pesticides, nitrates, nitrites, and also tells you how much chlorine is in your water. You can even find out the results within minutes of water testing.

Benefits of Water Testing Kit

The benefits of using a water testing kit are many. Here are the top few reasons you should get your test kit.

Stay Away from Contamination

This is of course the top reason you should test your water. If the test results clear the water of the presence of contaminants, well, it’s safe to use. Else, you know that you need to take measures soon to make your water safe for drinking.

Detects Contaminants

While we are aware that water we drink can be high in pollutants, knowing exactly which pollutant is the cause of contamination is important.

Helps get the Right Devices

We all want the best for our family and devices are a great way to ensure the same. But installing just about any device won’t help. If the water in your locality is high in certain contaminants and undesirable physical properties, installing the device that can free water from these will help solve the issue.

A water test kit is helpful in this measure as it precisely tells you the contaminants that you need to be fighting.

Detects Hard-to-Find Contaminants

Even the most treacherous contaminants can be traced and fixed using the water testing kits.

Insights into Health Concern

Health issues that you have always been trying to cure medically may have its roots in the water you drink. Analyzing water periodically, can pave the way towards freedom from such diseases.

The Convenience of Test Results at Home

This is one of the greatest pluses of a test kit. Whether you source your drinking water from a well or a tap, the test kit allows you to get details of the contaminants in the comfort of your home.

4 Types Of Water Test Kits

Testing kits can vary in terms of what they actually identify. In order to be sure that you get the best water test kit for your home, you must purchase the right variant to check the water quality.

For Contaminants

The kits that look for contaminants in the water are usually the more expensive ones. Still, they are items you should consider purchasing if you want to be certain that you are drinking safe drinking water.

These kits will usually check for bacteria, pesticides, heavy metals, and VOCs.


In the world of water testers, TDS stands for “total dissolved solids,” per Aquasana. Total dissolved solids account for salt and minerals that may be in your water.

TDS meters are not useful for the purpose of finding contaminants, but they should be helpful when you are trying to figure out if it’s time to change your water filters.

For pH

Devices that measure the pH level of your water will let you know how acidic or how alkaline it is. According to Healthline, water with a pH level lower than 6.5 can be considered unsafe to drink. On the other hand, alkaline water can have some positive effects on your body.

Use a pH tester to quickly see if the water you have at home is harmful or helpful.

For Water Hardness

Water hardness refers to the “amount of dissolved calcium and magnesium in the water,” per the United States Geological Survey. If your water features a high hardness level, that likely means that you will have to use more soap to clean with it.

A water hardness test strip can be used to determine the hardness level of the water you’re using.

3 Ways To Perform Water Tests

Test Strips

Test strips are most often useful if you are examining characteristics of your water such as its hardness and pH levels. The test strip can even provide you with the results within a short amount of time.

You will also be able to find other testing strips that can do more. They may even identify which contaminants are currently present in your home’s water supply.

Lab Testing

You won’t be the one conducting the lab tests if you use one of these kits. Instead, you will simply be tasked with collecting the samples as well as sending those to the manufacturers of the kit.

It can take anywhere between a week to three weeks before you receive the test results on your water quality.

Digital Meters

These are often the most convenient items that can be used for testing water and they return results almost immediately. The only real downside to using digital testers is that they can only measure the pH level and/or the amount of TDS in the water.

FAQs on Best Home Water Testing Kit

How often do I need water testing?

There is no objective answer to that. It really depends on where you live, the water quality and what contaminants you want to test the water for. Ideally, as per EPA recommendation, water should be tested once a year for microorganisms.
For elemental contaminants and harmful chemicals, water should be tested once every 2-3 years.
In case of flooding, earthquake, or any other land disturbance, water should be tested as soon as possible.

How do I determine if my water is contaminated?

The simplest and most convenient way to determine this is to use a drinking water test kit. It comes with directions for use and the collected sample can be sent to a lab that will analyze and send the report to you. Additionally, there are some labs that may even help fix the issues with the water by advising the right kind of devices and treatment methods.

Wrap Up

The best water test kit can have a significant positive impact on your quality of life. With the information you receive from the kit, you can find out if you’re drinking and/or using clean water. Invest in one if you want to ensure that you are only using the best kind of water at home.
