The Harmsco HB-10-5W Hurricane Bag Filter cartridge has a 5-micron nominal rating, making it effective for reducing sediment, dirt, rust, silt, and other particulate matter from your water supply. This pleated polyester media design offers a large surface area for superior dirt-holding capacity compared to standard string-wound or melt-blown cartridges, extending service life in high-flow applications.

The Harmsco HB-10-5W is specifically engineered to fit Harmsco Hurricane HUR-90, HUR-90-HP, HUR-170, and BF-1 series filter housings. It is not a universal cartridge — its unique pleated bag design with a sealing flange is built exclusively for Harmsco Hurricane systems. Always verify your housing model before ordering to ensure a proper fit and seal.

Service life of the Harmsco HB-10-5W depends on your water quality and flow demand, but typically the cartridge lasts 3 to 6 months in residential applications. In commercial or high-sediment conditions, replacement may be needed sooner. Monitor the pressure differential — Harmsco recommends changing the cartridge when the pressure drop reaches 15 PSI over the clean cartridge reading for optimal performance.

The Harmsco HB-10-5W cartridge supports flow rates up to 40 GPM (gallons per minute) when installed in a compatible Harmsco Hurricane housing. Its pleated polyester construction with 5 square feet of filtration surface area allows for high-efficiency sediment removal without sacrificing flow, making it ideal for whole-house, well water, irrigation, and light commercial applications.

The Harmsco HB-10-5W is a disposable cartridge, but it is constructed from durable, FDA-compliant polyester media that can be rinsed and reused a limited number of times in light-duty applications to extend its service cycle. For best filtration performance and water quality, Harmsco recommends replacing the cartridge once it has reached the recommended pressure differential or visible loading, rather than relying on cleaning.
