The Pentek ECP5-BB, 255490-43 Pleated Sediment Water Filter Cartridge is a whole home water filter that reduces extra-fine sand, dirt, silt, rust, and scale particles. The construction of this pleated water filter provides a excellent dirt-holding capacity while maintaining a high flow rate. This Pentek water filter also provides higher wet strength than regular cellulose cartridges. This 5 micron water filter contains more media surface area than most competitive cartridges. The standard 10 inch ECP cartridges contain six square feet of media, where most cartridges contain only 4.5 square feet. This replacement water filter cartridge fits Culligan HD-950 filter housing and should be replaced every four months.

It’s a quality built filter with rubber washers on top and bottom of the filter. This way very little water if any can bypass the filter. Cheaper filters don’t have the rubber washers. Also they don’t as much filter Media as the PENTEX ECP5-BB. You get what you pay for.

The Water filters came quickly. Was exactly what I ordered. Would buy from them again. Here is a photo of my water filter system with the water filter mounted to the wall.
