What Are “Forever Chemicals”?

Frequently Asked Quetions

What is the difference between undersink and countertop systems and whole home systems?

Undersink and countertop systems are filtration systems that reduce chemical contaminants and sediment from the faucet where it is installed (point-of-use) whereas a whole home filtration system does the same thing at the point where the water enters the home (point-of-entry), resulting in a higher quality of water throughout the entire home. Undersink and countertop systems are more cost-effective ways to improve your water at individual faucets.
