They are designed to allow maximum contact between the water and carbon, ensuring optimal adsorption. The construction of the cartridge allows water to enter at one end and pass through the entire length of the carbon bed before exiting the other end of the cartridge, while an internal expansion pad minimizes channeling or bypass. Before the water exits the cartridge, a post-filter helps reduce carbon fines and other suspended particles from the filtered water. The post-filter is permanently fastened to an innovative support basket ensuring that it is firmly se d and eliminating any potential for bypass. GAC Series Cartridges are available in a variety of sizes and flow rates, and effectively provide good general-purpose drinking water filtration. ## Features - EFFECTIVE REDUCTION OF BAD TASTE & ODORS to provide good general-purpose drinking water - FITS ALL 10" Pentair Pentek Big Blue or other 10" heavy duty housings and can replace any 10" x 4.5" carbon filter cartridge - POST-FILTER HELPS REDUCE CARBON FINES and other suspended particles from the filtered water - NSF INTERNATIONAL tested and certified for your peace of mind - 12,500 GALLON CAPACITY.

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. ### ⭐⭐⭐⭐⭐ Awesome filter ! *by on Reviewed in the United States 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 ... --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/601280635-pentair-pentek-gac-bb-big-blue-carbon-water-filter-10](https://www.desertcart.jp/products/601280635-pentair-pentek-gac-bb-big-blue-carbon-water-filter-10) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-07*
