Clean water is important. It is important to have it in your whole home. Most people use tap water for several things around the house, so why not try and get the best quality water in your entire water supply, especially if your water source is a well? Around 13 million homes in the US use a private well for drinking water, according to an article by the EP. There are obvious benefits, but there are also downsides.

Well water can contain impurities like bacteria – E. Coli, protozoa, as well as some viruses that might make you sick. Read more about it on the Minnesota Department of Health. There are also many hard water minerals, such as calcium and magnesium, and iron, and other harmful contaminants that may cause a mineral buildup in your home’s water pipes and heating system. They can also diminish your appliance’s lifespan.

This is why many people turn to home water filtration systems (or whole house water filter systems, as they are often called). Filtered water can take care of all these problems in your household and more. This is why we have compiled this list to help you choose which is best to improve the water quality in your home!
