Description
Water below pH 6.8 can be corrosive to plumbing. The Crystal Quest Acid Neutralizing Whole House Water Filter passes incoming water through crushed white marble (calcium carbonate) media, raising acidic water toward neutral before it reaches the rest of the home.
Highlights
- Calcium carbonate media raises low-pH water to neutral for less corrosive water throughout the home
- Automatic backwashing cleans the media bed and helps prevent compaction
- 20" sediment pre-filter and 20" solid carbon post-filter around the neutralizing tank
- Choose standalone, with a SMART filter, with a softener, or with both
- Fiberglass or stainless steel tank in 1.5 or 2.0 cubic feet of media
Details
Avermont Direct is an authorized Crystal Quest dealer. This system is designed solely for acid neutralization of water below pH 6.8; add the SMART filter for broader filtration or the softener if hardness is a concern. The media dissolves slowly as it works and needs to be refilled periodically.
