Pentek CBC20-BB CBC-20BB Standard Residential Whole House Water Inch, Block Cartridge with Bonded Powered Activated Carbon (PAC) Filter, 4.5” x 20”, 0.5 Micron, Extruded, White

Good quality

I like the 1 micron rating

Why did you pick this product vs others?: This is a direct brand replacement. I believe it is the best value filter you can get. It replaced our last filter we have been using for a year, way beyond it's volume and expiration period and still removes most of that reservoir water smell from the tap. This replacement along with a Brita filter pitcher for a fringe improvement gives us near snow melt well water quality you get in the high mountains in the spring. Our tap water isn't anywhere near the hard water you get from a southern California tap but has a bit of lake water smell, occasional mold fungus that immediately starts growing on the toilet bowl with a lot of new PVC pipe leaching into it, while on it's way here. Following any fungus blasts some kind of fungicide usually follows. Needless to say, a chemical reducing .5 micron biological safe water filter is a must here. This is the one that has led the pack for us.

Conforme et facile d’installation

Been using these as our second stage filter in our home system for many years now (first stage is polypropylene filter). 0.5 micron is much finer filtering than what you typically find for a carbon block filter. The extra cost is worth it, I think.

High quality and true dense 0.5 microns. The water from my well is pretty good and odorless, but has a color from tanins (I had already tested iron filters). In the pictures, the first 2 cups on the right were 2 different carbon filters of 5 microns and different brands. Then I tested this one, and bingo, the cup on the left was crystal clear. Even the weight of the filter is a lot heavier than the other filters, and while the other filters don't restrict flow, this one does so, I don't think it works high volume applications but for drinking water it's awesome.

Inodore e perfetta.
