Pentair Pentek CRFC20-BB Big Blue Carbon Water Filter, 20-Inch, Whole House Chloramine Reduction Carbon Replacement Cartridge, 20" x 4.5", 25 Micron

Pentair Pentek CRFC20-BB Big Blue Carbon Water Filter, 20-Inch, Whole House Chloramine Reduction Carbon Replacement Cartridge, 20" x 4.5", 25 Micron

Q: Do you have drop in water pressure?

We have had no drop in pressure. It is a great filter I have several larger micron filters in front of this one to capture some of the larger particles so this one will last longer and has worked out great.

Q: How long do these last. Average use 2 people in house.

I run 35000 gallons through them which for a house of 3 lasts about nine months.

Q: Does the 10" filter out Chloramine?

Yes. Chloramine Taste & Odor Reduction (3.0-0.5 ppm) @ flow rate (gpm): 10,000 gallons @ 5 gpm 25,000 gallons @ 2.5 gpm

Q: How long do these last

I replace every 4 months but we go through a lot of water

Much better than the GAC to flow filter

The radial flow cartridges last much longer and work better than the top/bottom flow units. They are easily worth double the price.

Works well for brewing

Use it at a small commercial brewery, does the job of removing the chlorine/chloramine from the water and the beer tastes great so works well for me.

Works fantastically. The final test will be time as I anticipate it working for 2 years before replacement, maybe a little longer even.
