Pentair Pentek ECP5-20BB Big Blue Sediment Water Filter, 20-Inch, Whole House Heavy Duty Pleated Cellulose Polyester Replacement Cartridge, 20" x 4.5", White End-Cap, 5 Micron, Pack of 6

It is what it is advertised as.

For my well water, great pre-filter

Unlike some comments, the Pentair, Pentek ECP1-20BB 1-Micorn filter does not come packaged with notations not to use with non-chlorinated water. We use it on our well and even with just pressure tank pressure (Less than most city supplied water), it works superbly. Will buy again. PS: We have a professional well company who also recommends this filter.

work great

Filters fit great in the housing and after checking on them after 30 days of use, they seem to be stopping all of the sediment as intended.

I've been using these filters in our whole-house rainwater system that serves as our primary potable water source for 9 years, so I've probably bought them over fifty times. They hold together well and filter the water exactly as they should. As long they make them I'll continue to use them.

Does the job as intended

This heats a 12x12 3 season room very quickly and doesn't have to constantly run, but that could be because the space is well insulated. Still, very satisfied with this heater.
