I have the 3 stage Home Master water filter system, these look to be the same size.** A: Did it fit your home master filtration? Did the filter work as good as the crffe-20bb iron filter? It is such big difference in price I am tempted to buy this instead of the crffe-20bb **Q: What is the flow rate in GPM through this filter** A: 6 GPM (gallons per minute) is recommended flow rate. **Q: my water has a slight yellow tint when tub filled and leaves orange stain around drain. It only has very slight odour. Will your filter remove this. h** A: There are two parts to the answer. Yes the iron filter removes most of the yellow and smell. When a carbon block is then used, the water is very clean and good. **Q: Does it have Warning 65 on it?** A: It does have a prop 65 warning on it but I do not know if it is because of the filter or the rubber washers that are used to seal the filter in the housing. ## Frequently Bought Together - Pentair Pentek RFFE20-BB Big Blue Water Filter, 20-Inch, Whole House Radial Flow Iron Reduction Replacement Cartridge, 20" x 4.5", White - Pentair Pentek RFC-20BB Big Blue Carbon Water Filter, 20-Inch, Whole House Heavy Duty Radial Flow Carbon Replacement Cartridge with Granular Activated Carbon (GAC) Filter, 20" x 4.5", 25 Micron - Pentair Pentek DGD-5005-20 Big Blue Water Filter, 20-Inch Whole House Sediment Filter Cartridge Replacement, Dual-Gradient Density Spun Polypropylene, 20" x 4.5", 5 Micron, Pack of 1, White --- ## 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.gr/products/3678657-pentair-pentek-rffe20-bb-big-blue-water-filter-20-inch](https://www.desertcart.gr/products/3678657-pentair-pentek-rffe20-bb-big-blue-water-filter-20-inch) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-25*
