Home Water Quality

The Environmental Protection Agency (EPA) states that no matter where you live in the United States, some toxic substances are likely to be found in the groundwater, impacting your water quality at home. The agency estimates that one in five Americans consumes tap water that violates safety standards under the Clean Water Act. We're not fear-mongering with this information, but we are suggesting that home water quality is more of a concern than many people realize.

The two basic processes used to improve water quality in the home are filtration and purification. The word "filter" usually refers to a mechanical filter, which strains the water, and/or a carbon filter system, which reduces certain impurities by chemically bonding them - especially chlorine, lead, and many organic molecules. Purification refers to a slower process, such as reverse osmosis, that greatly reduces dissolved solids, hardness, and certain other impurities, as well as many organics. Many systems combine both processes.

Make sure the claims of any home water purification or filtration system you consider have been verified by National Sanitation Foundation (NSF) or independent testing.

"Our advice before purchasing a home water purification or filtration system is:

  1. Test your water so you know precisely what impurities and contaminants you're dealing with
  2. Buy a system that is designed to treat the problems you have
  3. Check manufacturer data sheets to make sure claims about what the system treats have been verified by the National Sanitation Foundation (NSF) or another third party"
