Water Testing Kit Buyer’s Guide

So, were you able to make a decision after going through our list of recommendations? If not, there’s nothing to worry about, as knowing just the brand names and a few pros and cons is barely enough information while buying the best water testing kit.

There are a few other factors to consider as well which will help you buy the right option based on your requirements. On that note, we have explained all the important factors in detail in this section to help you make an informed purchase. 

So, we strongly recommend reading it till the end. 

  1. Testing Procedure

The testing procedure has got to be the most important factor that you need to consider while buying a water testing kit. To get reliable results, we recommend going with a unit that lets you send the samples to a testing facility. But, one minor drawback of this procedure is that you have to wait almost a week for the results.

However, if you want the test results in a short period of time, a home test kit would be perfect for you. On the flip side, the results won’t be 100% accurate. 

  1. Contaminants

Some units can test for a wide variety of contaminants such as iron, copper, chlorine, and lead, while others test for only 2 or 3 contaminants. If you are aware of the impurity you are testing for, we would suggest going with the latter option. 

However, if you want to have a detailed insight into the quality of your water, we recommend going with a kit that tests for a broader range of contaminants. 

  1. Water Source

Last but not least, you need to be sure about the type of water you will be testing. In general, most water testing kits are only compatible with a specific source of water. For example, some are recommended for drinking water, while others are for pool or well water. 

Now, obviously, there are going to be a lot of differences between the contaminants found in the water you drink and in the water you swim. Therefore, we recommend buying a product that caters to a particular water source.

A water testing kit lets you know about the contaminants present in your water in just a few minutes. So, if you want to learn about the quality of a water source, it is essential to buy a reliable water testing kit.  

With that, we have reached the end of our review-based guide; hopefully, it will help you make the right choice. However, before wrapping up, we would like to mention our favorites from this list. 

The best overall product is the VARIFY Premium Drinking Water Test Kit, mainly because it tests 16 various parameters and is easy to use. Closely following it is the API Freshwater Master Test Kit, which is a budget-friendly model and is capable of monitoring numerous problems. 

But, if you are looking for an innovative option that features a mobile app for tracking, we recommend going with the JNW Direct Pool and Spa Test Strips. So, that’s all for now. See you soon!
