Pentair Pentek EPM-20BB Big Blue Carbon Water Filter, 20-Inch, Whole House Modified Epsilon Carbon Block Replacement Cartridge with Bonded Powdered Activated Carbon (PAC) Filter, 20" x 4.5", 10 Micron | Economical Carbon Block Reduces Chlorine Taste and Odor Plus Sediment; 20" x 4.5", 10 Micron, 30,000 gal

Exactly as described works well

I replace these every six months or so. I have been getting them from this vendor for a while and the vendor is reliable and the price is reasonable.

When we moved into the house, I had a plumber install a water softener in the garage and a RO filter at the kitchen sink.Before everything, he installed the canister for this Big Blue filter. Our Phoenix suburb city water isn't bad, but we do have high content of dissolved solids and minerals because a blend of our water comes all the way from the Colorado river and everything it picks up along the way.I have to say that using this as a pre-filter has help eliminate any problems with the water softener mechanism and resin. When I do the ritual slight drain of the electric hot water tank, there is no sediment and the tank hasn't leaked so far after 16 years. The RO system filters and membrane have long life.As the number of people under roof have declined as empty nesters, I now change the filter about every 18 months.Simple to change, although my technique involves using two of the custom wrenches -- one pull and one to push to get the spinning started. I also keep the threads and seal properly lubricated.I have found that this same Pentek numbered carbon filter as originally came in the housing remains the one we need.

I was using the 2-5 micron model and it restricted the flow where as this one works much better flow wise.

Always a reliable brand. You get what you pay for.

improved water quality

Really reduces our sulphur odor from our well water. Lasts several months and doesn’t drop pressure. We generally replace when the sulphur smells starts returning.

Perfect fit for my PennOlax Big Blue filter. Will buy again when it's time to change.

Works good for our water filtering system and less expensive than purchasing from plumbing supply store

This was the first time that I ordered these filters for my water system and they were exactly what I needed.
