If you are dealing with large rust and other sediment particles in your water you should be fine with a 5 micron sediment filter. For wells I like pleated filters like this: https://amazon.com/dp/B074FW96PG. If iron is dissolved in your water, you need something that filters iron/manganese like this: https://amazon.com/dp/B09JWP92PD **Q: How do you contact customer support? The inlet and outlet ports leak no matter how much ptfe tape or thread sealant used.** A: I put an O-ring (# 18) inside each port before the brass bushing. Then I coated the threads with sealant and 10 wraps of teflon tape. I think there may be a design flaw, it shouldn't be that difficult. **Q: The filter housing leaks profusely. i checked the o-ring/tested it without a filter to no avail. anyone had this problem and been able to fix it?** A: Try to lube the o-ring with some coconut oil or silicone lube and reassemble. Also, if you are using carbon filters, I have seen that sometimes they are just a bit too tall, and so removing one of the gaskets allows the tank to be tightened a bit further, causing a seal. If you write to the company for support, they have a support rep out of Canada who is fantastic. Be sure to include your Amazon order number and you may want to request a call back (specifically by phone) so that they will route it to him early. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***Y on 15 December 2022* ### ⭐⭐⭐⭐ Review *by M***Y on 14 January 2026* ### ⭐⭐⭐⭐⭐ Review *by N***N on 24 January 2026* ## Frequently Bought Together - SimPure Whole House Water Filter Housing (DB20P), 20" x 4.5" Sediment Carbon Filter Universal Housing, Pre-Filtration System for Well and City Water, 1" NPT Port, Pressure Release - 10" x 4.5" Whole House Sediment Water Filter, SimPure 5 Micron 10-inch Big Water Filter Replacement Cartridge Compatible with W15-PR, DGD-5005, FP15B, HD-950A, GXWH35F, GXWH30C for Well Water 4-Pack - 5 Micron 10" x 4.5" Sediment and Carbon Whole House Water Filters SimPure Replacement Cartridge for GE FXHTC, GXWH40L, RFC-BB / 155141-43, FC15B, HB18B, WRC25HD, WDGD-5005, W10-PR, W15-PR, 3-Pack --- ## 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.sn/products/298586684-upgrade-whole-water-filter-housing-20-inch-big-blue-filter](https://www.desertcart.sn/products/298586684-upgrade-whole-water-filter-housing-20-inch-big-blue-filter) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-09*
