The Harmsco HB-20-20W is a 20-inch pleated polyester replacement filter cartridge with a 20-micron nominal rating. It is specifically designed for use in Harmsco Hurricane and BetterFlow housings, offering high dirt-holding capacity and extended service life. The pleated design provides significantly more surface area than traditional string-wound or spun cartridges, allowing for higher flow rates with lower pressure drop. It is ideal for sediment removal applications including well water, irrigation, pool, and commercial water filtration systems.

The HB-20-20W cartridge is engineered to fit Harmsco Hurricane series housings (HUR-40, HUR-90, HUR-170) and Harmsco BetterFlow housings that accept 20-inch cartridges. It uses Harmsco's proprietary single-cartridge-per-housing design, so it is not interchangeable with standard 2.5" x 20" Big Blue-style filters. Always verify your Harmsco housing model before ordering to ensure proper fitment and sealing.

Replacement frequency depends on your water quality and flow demand, but the HB-20-20W typically lasts 3 to 6 months under normal residential or light commercial use. Because of its high surface area pleated construction, it can filter significantly more sediment than comparable cartridges before clogging. A reliable indicator for replacement is a pressure drop increase of 10-15 PSI across the housing, or a noticeable reduction in flow rate. In heavy sediment or well water applications, inspection every 1-2 months is recommended.

Yes, one of the key advantages of the HB-20-20W is that its pleated polyester media is designed to be rinsed and reused multiple times, extending its effective life well beyond single-use cartridges. To clean, remove the cartridge and spray it down with a garden hose from the outside in to dislodge trapped sediment. This reusability makes it a cost-effective solution for high-sediment applications such as well water, pool pre-filtration, and irrigation systems.

At its 20-micron nominal rating, the Harmsco HB-20-20W is designed to capture sediment-based particles including sand, silt, rust, scale, dirt, and other suspended solids larger than 20 microns. It is primarily a mechanical sediment filter and is not intended to reduce chlorine, taste, odor, lead, or chemical contaminants. For comprehensive filtration, it is often used as a pre-filter ahead of carbon or specialty treatment stages in multi-stage filtration systems.
