High flow filter cartridges

Last updated: 2026-09-29

High flow filter cartridges are large-diameter (6") liquid filtration elements built to handle high flow rates with fewer elements and smaller housings — cutting change-out labor and upfront capital cost. The result is much faster, easier filter change outs. In addition,the inside to outside flow allows for excellent dirt holding capacity, extending the time between filter change outs. Filter housings are also available and because of the filters high flow and dirt holding capacity, smaller systems are possible, reducing upfront capital costs.

    High flow filter cartridges

    High Flow filter cartridge feature a larger geometry to handle higher flows with fewer filter elements. The result is much faster, easier filter change outs. In addition,the inside to outside flow allows for excellent dirt holding capacity, extending the time between filter change outs. Filter housings are also available and because of the filters high flow and dirt holding capacity, smaller systems are possible, reducing upfront capital costs.

High Flow Filters vs Standard Filter Cartridges:

High flow filters are engineered for high-capacity liquid filtration. A 6" diameter and deep pleated media let one element replace many standard 2.5" cartridges, so you need fewer housings, less floor space and less change-out labor. Choose high flow when flow rate, dirt-holding capacity or system footprint matter; choose standard cartridges for low-flow or point-of-use duties. KOSA high flow elements retrofit major competitive housings.

Frequently Asked Questions

What are high flow filters used for?

High flow filters are used wherever high liquid flow rates and long service life matter — water systems, pre-RO, food and beverage, chemicals and drinking-water plants.

How do high flow filter cartridges differ from standard cartridges?

High flow filter cartridges use a larger 6" diameter and pleated media to deliver far higher flow and dirt-holding capacity with fewer elements and a smaller housing than standard 2.5" cartridges.

What micron ratings are available?

KOSA high flow filter cartridges cover absolute ratings from 1 to 150 microns, in PP or polyester media, with EPDM, silicone, Buna-N or Viton seals and lengths 10–50 inch (250–1000 mm).
