3 sold in last 24 hours
- REDUCES SEDIMENT AND PARTICULATES - Pleated cellulose polyester media captures dirt, sand, silt, and rust down to 50 microns while maintaining high flow rates for whole house water filtration
- 36 SQUARE FEET OF FILTER MEDIA - Pleated design provides significantly more surface area than standard cartridges for extended dirt-holding capacity and longer filter life
- SONICALLY WELDED FOR EFFICIENCY - Overlap seam is sonically welded to reduce internal bypass and improve filtration efficiency; resin-impregnated fibers provide higher wet strength than regular cellulose
- FITS 20" BIG BLUE HOUSINGS - Drop-in replacement for any standard 20" x 4.5" Big Blue or heavy-duty filter housing; yellow endcap is color-coded for easy micron identification at replacement

Select a product to estimate shipping.The Pentair Pentek ECP50-20BB is a 50-micron pleated sediment filter cartridge designed for whole house water filtration in standard 20" x 4.5" Big Blue housings. The filter media is constructed from a blend of resin-impregnated cellulose and polyester fibers, providing higher wet strength than standard cellulose cartridges. The pleated design delivers 36 square feet of filter surface area, extending dirt-holding capacity and filter life compared to non-pleated alternatives.
The ECP50-20BB features a sonically welded overlap seam that reduces internal bypass for improved filtration efficiency. The cartridge is built around a polypropylene core for added structural strength, with polypropylene endcaps and gaskets for a secure seal. It is compatible with both chlorinated and non-chlorinated water supplies.
This cartridge operates at less than 1 psi pressure drop at 20 gpm, with a temperature range of 40-125 degrees F. The yellow endcap is color-coded for quick 50-micron identification during filter changes. Replace every 3-6 months or when you notice a decrease in water pressure.
