How a whole home water filter works

Depending on which whole home filtration system you choose, your water will go through several stages of treatment to reduce as many contaminants as possible.

In general, all whole home filters have a multi-stage process that includes pre-filtration, filtration and post-filtration phases.
 
Pre-filtration
1. Pre-filtration
Reduces the largest water contaminants such as sediment and silt.
Filtration
2. Filtration
An activated carbon filter paired with additional custom filters reduce chlorine, chloramines and contaminants.
Post-filtration
3. Post-filtration
Helps to reduce any leftover sediment and contaminants before the water reaches your tap.
