HUM Chemical Free FOK Iron/Sulphur/Manganese Filter 2.0 System Resource & Maintenance Guide
• Homeowners considering the HUM Chemical Free FOK Iron/Sulphur/Manganese Filter 2.0
• Customers who already own this system and want to maintain it properly
• Anyone looking to understand how water softeners work and what up keep looks like long-term
The HUM Chemical-Free FOK filter uses air over media oxidation technology:
Air Injection Oxidizes Contaminants: An advanced electronic valve draws air into the media tank, forming an air “cap” at the top. Incoming water is sprayed through this air space, beginning oxidation of iron and sulphur.
Media Traps Oxidized Particles: The oxidized iron and sulphur bind to the media inside the tank, preventing them from continuing through the plumbing.
Automatic Backwashing: Every few days the system automatically backwashes, reversing flow to flush out accumulated iron, sediment, and other contaminants to drain. After backwash, it rebuilds the air cap and resumes service.
No Filter Cartridges: There are no disposable cartridges to replace, and no chemical additives in your water, keeping maintenance simple and water natural.
