5900-BT-AIR Sulfur Odor Filter (1.5 CF / 1054) — More Flow, Same “Rotten Egg” Odor Removal
If your well water smells like sulfur (hydrogen sulfide), this whole-house air-injection oxidizing filter is designed to eliminate odor and improve taste without chemical feed pumps. The valve maintains an air pocket at the top of the tank to oxidize sulfur odors as water passes through, then a catalytic activated carbon bed removes the oxidized compounds and remaining odor.
- Odor removal: rated up to 8 ppm hydrogen sulfide (H2S)
- Oxidation in one tank: air pocket + catalytic carbon media bed
- Automatic backwash: cleans media and flushes trapped sediment to drain (commonly every 4–6 days)
- Smarter monitoring: 5900-BT valve with optional Legacy View Bluetooth/app monitoring
- Saves water vs nightly-backwash designs: draws in fresh air independent of the backwash cycle
Note: If your hydrogen sulfide levels are extremely high (over 8–10 ppm), you can further improve odor removal by pairing this system with a hydrogen peroxide injector ahead of the filter. Learn more about peroxide systems at Hydrogen Peroxide Well Water Systems .
Who the 1.5 CF model is for
This size is a solid “step up” when you want more whole-house flow than a 1.0 CF unit can comfortably deliver. Your sizing guide targets 1–2.5 bathrooms with about 7 GPM service flow.
