Best Water Test Kit

Water testing is crucial for homes with a water source that is not very stable. For instance, they may experience frequent water interruptions and the like. In this article, we are going to discuss the importance of a water test kit, why you need one at home, and how they are used.

Why you need to test water quality at home

Testing water at home has the following benefits:

  1. Become safer against diseases. If you test water at home, you will have less likelihood of catching water-borne diseases such as diarrhea and other bacterial infections. Knowing the quality of water you have at home may prompt you to buy a water filtering device to make sure that you only get clean water for drinking, cooking, and overall consumption.
  1. Ensure a clean water supply for drinking. Testing your water quality at home helps you to become more aware that your drinking water is safe to consume. This is important if you have kids at home as well as elderly people who are sensitive to water quality for drinking.
  1. Lessens heavy metals in water. If you have less heavy metals in the water you are drinking, you will be less prone to health problems. While it is okay to keep magnesium and calcium in the water, certain heavy metals such as fluoride and arsenic may not be ideal.
  1. Identifies if there are pesticides in the water. Those who live near a farm may be at risk for pesticides and herbicides that may be present in their water source. To protect you and your family, you can test the water to see if any of such can be present.
  1. Determines helpful minerals. Calcium and magnesium are needed by the body as minerals that can help boost our health and our overall immune system. If they are present in water, they should not be filtered out by your current water treatment plans.

What Do These Kits Test For?

Water test kits usually test the pH or alkalinity/acidity of the water, as well as for any of the following potentially dangerous elements:

  • Fluoride
  • Nitrate
  • Arsenic
  • TDS (total dissolved solids)
  • Iron
  • Manganese
  • Chlorine

What is the Best Water Test Kit?

Here are our top picks for the best water test kits:
