This premium filter cartridge from Water Softener Plus delivers consistent filtration performance, ensuring your water treatment setup stays efficient and your appliances protected.

Key Benefits

• Protects your water system from fine sediment and debris down to 5 microns
• Extends the lifespan of downstream equipment by reducing clogging and wear
• Fits standard 20" Big Blue housings for easy integration and replacement
• Durable melt blown construction ensures consistent filtration performance
• Reduces maintenance frequency by efficiently capturing contaminants

How It Works

This melt blown filter cartridge uses a tightly wound polypropylene fiber matrix that traps particles as water flows through it. The 5 micron rating means it filters out small sediment, rust, sand, and other suspended solids that can degrade water quality and harm your equipment. Installed inside a standard 20" Big Blue housing, it acts as the first line of defense in your water treatment system, preventing larger particles from reaching more delicate filtration stages or appliances.

By capturing contaminants early, it helps maintain system pressure and reduces strain on pumps and valves, contributing to more efficient operation and longer service life.

What to Expect

Once installed, you’ll notice clearer water free from visible particles immediately. Over the first few days and weeks, the cartridge will trap accumulating sediment, helping to protect your plumbing and appliances. Regular replacement keeps your system running smoothly without pressure drops or flow restrictions.

With proper maintenance, this filter cartridge offers reliable performance and consistent filtration efficiency, making it a dependable component in your water treatment routine.
