RainSoft Water Treatment Systems

RainSoft improves the Quality of Life for our customers and their families by offering them environmentally responsible air and water treatment solutions for their homes.

DRINKING WATER SYSTEMS that provide bottle-quality, crystal clear water for drinking and cooking...without the plastic bottle.

WATER TREATMENT SYSTEMS that save money by reducing energy and soap consumption. Water-using appliances last longer, and bathing and shower has never felt better!

AIR PURIFICATION for the entire house, not just one room. RainSoft air purification products mount directly into the duct, providing protection and peace of mind...silently and out of sight.

It has been over 55 years since the first RainSoft water conditioner was sold from a small garage just outside of Chicago, Illinois. Since that day in 1953, RainSoft has become an industry leader in treating, filtering and softening water for well over one million homes and businesses throughout the world.
