Review: perfect fit - perfect repacement, good price for this filter, it was 2x the price at dealer, no issues.
Review: What a difference - I had a DIY dual filter setup with Pentek 158643 3/8" #10 3G Slim Line Clear Filter Housings for my cold sink water. A while back I downgraded to the cheap generic filters, and noticed a huge downgrade in taste. It was not drinkable water. So to fix it, I added a third Pentek filter housing, and went back to what worked- genuine Pentek filters. The sediment filter I had didn't seem to fit properly, I don't think it sealed at all, so I ditched that completely and used a cheap but working DuPont WFPFC8002 Universal Whole House Carbon Wrap 2-Phase Cartridge as a sediment filter. Second in line I swapped the $6.50 DuPont with the $9.63 Pentek CBC-10 Carbon Block Filter Cartridge, 9-3/4" x 2-7/8", 0.5 Micron, a solid secondary filter w/ a perfect fit. The Pentek feels like it weighs 3x as much as the Dupont, no question it's worth the few extra dollars. The third and final filter was the hardest decision. I have tried both the Pentek ChlorPlus 10 Carbon Block Filter Cartridge, 10" x 2-1/2", 1 Micron, and the Pentek CC-10 Coconut Carbon Drinking Water Filters (9.75" x 2.875"), both of which were fantastic, make a noticeable difference to the taste of the water, and costs about $15-20. Instead, I went with a $12 option, the Pentek GAC-10 Drinking Water Filter (9-3/4" x 2-7/8"), hoping it would deliver similar results, especially considering the town water is fairly clean to begin with, ppm around 48. Would probably go with the CC-10 next time, but I'm very happy with the current results. The Pentek filter and housing combo really restored my drinking water back to amazing. Neighbors knock at my door with 5 gallon jugs because they can taste the difference too.

## Questions & Answers

**Q: Will this filter fit the whirlpool whole home filtration system you purchase at Lowes?**
A: It looks like there are several types of whirlpool systems sold at Lowes - some (such as 84219910) appear to use standard 10" filter sizes and this should fit inside of those.    Other models appear to take specialty or big blue sized filter cartridges.

**Q: Where is the difference between gac-10 and cc-10? which is better?**
A: The GAC-10 is a coal based filter & the CC-10 is a coconut based filter. We feel the GAC is a better filter.

**Q: how often should these filters be replaced**
A: These are rated at 5000 gallons.  Most manufacturers recommend replacing at six months, but based on use, you may be able to get a year or more of service out of it.  When your water begins to taste the same as it does from unfiltered faucets, or if water flow slows noticeably, then it might be time to replace the filter.

**Q: Will this, and the carbon block cbc-10 fit a puromax hr-3?  thanks!**
A: Check your old filter model number and search for your filter.

### ⭐⭐⭐⭐⭐ Awesome filter !
*by A***O on August 17, 2025*

There is a reason why they cost a bit more than most. They have a lot of granular carbon. You get what you pay for.. I have yet to install them in my 5 stage watts RO system. which has been resulting in 4ppm. for one year prior to changing all filters... The RO dow tech membrane i only replace every 5 years... my pre sediment is 1 micron ...
