5900-BT-AIR Sulfur Odor Filter (2.5 CF / 1354) — High-Flow Whole-House Odor Control
If your well water smells like sulfur (hydrogen sulfide), this whole-house air-injection oxidizing filter is engineered to reduce or remove that odor without chemical feed pumps. The system creates an air pocket above the media to oxidize sulfur as water flows in, and a catalytic activated carbon bed captures the oxidized compounds and residual odor for cleaner, fresher water.
- Odor removal: designed for hydrogen sulfide up to 8 ppm
- Oxidation plus filtration: uses air pocket and catalytic carbon media
- Automatic backwash: media is periodically rinsed and refreshed (commonly every 4–6 days)
- Smart control: 5900-BT valve with optional Legacy View Bluetooth/app connectivity
- No chemicals required: treats sulfur odors with air and carbon alone under typical conditions
Extreme sulfur levels: For hydrogen sulfide levels above 8–10 ppm, this filter can be paired with a hydrogen peroxide injection system ahead of it to improve oxidation and help protect the carbon media. Learn more about peroxide systems at: Hydrogen Peroxide Well Water Systems .
Who the 2.5 CF model is best for
The 2.5 CF size delivers the highest service flow in this series, making it well suited for larger homes with multiple simultaneous demands. It’s typically matched with homes that have 2–4 bathrooms and a target service flow near 10 GPM.
