20 x 4.5 Inch Pleated Filters
20 x 4.5 Inch Pleated Filters
Pleated filters offer higher dirt-holding capacity than string-wound or spun polypropylene cartridges — the deeper, accordion-style media surface area captures more particulate before pressure drop increases, which means longer service life between changes in demanding applications.
This collection covers pleated sediment cartridges in the 20 x 4.5 inch Big Blue format, from 1 to 50 microns. It's one of three media-specific sub-collections in this size — for carbon block options see our 20 x 4.5" Carbon Filters, and for standard spun/dual-gradient sediment see 20 x 4.5" Sediment Filters.
Brands available:
- Pentek R30, ECP, and S1 series — reliable pleated polypropylene in a range of micron ratings for standard whole house sediment applications
- Harmsco Calypso Blue — commercial-grade pleated cartridges designed for higher flow rates and more demanding sediment loads
- Tier1 comparables — aftermarket pleated cartridges engineered to match Pentek dimensions and performance
Prices start at $20.86. Not sure which micron rating or brand suits your system? Call 1-800-277-3458.
