Complete Home Package
Carbon filter, water softener, and reverse osmosis drinking water system — every drop of water in the house, treated. Chlorine removed at the entry, soft water everywhere, purified water at the kitchen sink.
See full pricing →Softener + RO Bundle
Water softener plus reverse osmosis. Recommended for homes on private wells (wells aren't chlorinated, so the carbon filter isn't needed). RO especially valuable for nitrate concerns in agricultural well water.
See full pricing →Specialty: Backwashing Carbon Filter
For homes with chloramines, very high chlorine, heavy metals concerns, or customers who want 5-year set-and-forget media life. Requires a drain line and electrical outlet. Available by consultation — ask Chad during your free water test.

The chlorine the city adds to keep water microbiologically safe slowly oxidizes the resin inside any water softener. Without a carbon filter ahead of the softener, you can lose years of life off the resin. The cartridge filter handles that — and as a bonus, every tap in the house runs dechlorinated water. That's why we bundle the two together as the standard recommendation for city water homes.
Free Water Test — No Obligation
Before recommending anything, we test your water and tell you your actual hardness number and chlorine level. If you don't need a system, we'll say so. No sales pitch, no pressure.
