Nitrate doesn't look or smell like anything in your water. It gets there through fertilizer runoff, septic systems, and groundwater contamination -- and standard filters don't touch it. If you're on a well in agricultural country, there's a real chance your water tests above the EPA's 10 mg/L limit. The Crystal Quest Nitrate Whole House Filter uses ion exchange resin specifically designed to pull nitrate out of every tap in your home.
Important: unlike most contaminants, boiling water actually concentrates nitrate. A dedicated nitrate filter is the correct solution.
Nitrate Whole House Water Filter Key Features
- Ion exchange resin targets nitrate directly -- not a carbon filter workaround
- ERA 6500 & 9500 media inhibits bacteria growth in the filter bed
- Automatic backwash and regeneration cycle -- regenerates every 20-30 days depending on nitrate load
- Available in 1.5 or 2.0 cubic feet of resin; fiberglass or stainless steel tank
- Add SMART Filter to also remove heavy metals, chlorine, chloramines, and organic contaminants
- Add Water Softener to address calcium and magnesium hardness in the same system
- Pre and post-filtration included: sediment cartridge in, carbon block out
- ISO certified components; BPA-free materials throughout
Note on stainless steel tanks: High humidity or salt exposure can cause pinholes or rust on stainless tanks. Choose fiberglass if your installation site has these conditions.
