5900-BT-AIR Sulfur Odor Filter (2.0 CF / 1252) — Stronger Whole-House Odor Removal
If your well water has a sulfur smell (hydrogen sulfide), this whole-house air-injection oxidizing filter will significantly reduce or eliminate the odor and improve taste. Air is drawn into the tank to create an oxidation zone, and a catalytic activated carbon bed removes the oxidized compounds and residual odor without the use of chemical dosing pumps.
- Odor removal: rated up to 8 ppm hydrogen sulfide (H2S)
- Oxidation plus filtration: air pocket + catalytic carbon media bed
- Automatic backwash: interval backwash and rinse (commonly every 4–6 days)
- Smart control: 5900-BT valve with optional Legacy View Bluetooth/app monitoring
- Efficient design: no chemical feed required for typical sulfur odor removal
Extreme sulfur levels: For hydrogen sulfide above 8–10 ppm, consider adding a hydrogen peroxide injector system upstream of this filter. Peroxide improves oxidation before the carbon bed and helps protect media life. See your options here: Hydrogen Peroxide Well Water Systems .
Who the 2.0 CF model is best for
The 2.0 CF size provides higher whole-house service flow than the 1.0 CF or 1.5 CF models. It’s a strong choice for homes with 2–3 bathrooms and typical service demand around 9 GPM.
