I have been getting them from this vendor for a while and the vendor is reliable and the price is reasonable. ### ⭐⭐⭐⭐⭐ First In Line *by on Reviewed in the United States November 3, 2024* 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. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/3924265-pentair-pentek-epm-20bb-big-blue-carbon-water-filter](https://www.desertcart.com.pa/products/3924265-pentair-pentek-epm-20bb-big-blue-carbon-water-filter) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-08-05*
