If not, what is the part number for the "o-rings" and where do you order them?** A: The O rings do not come with the replacement filters, you need to buy them from Water Express. **Q: So the pentek, ispring, express, igeek and ect. filters will "all", work as long as the housing is 4.5 x 20"? but filter quality is diff?** A: Well dont know all those but If the housing is the same it should. I had ispring setup and just upgraded the filters to heavy metal filter set and they are great! No issues. Hope that helps **Q: how to open the blue housing ? no matter what I tried I can not open the blue houseing to replace the filter** A: You first have to shut the water off to the system...Next you have to release the pressure in the system, there should be a red button on top of the system press that button and watch the pressure drop on the gauge..Note there will be some water so have a towel ready ..Next use the wrench that came with the system when you bought it ... It looks like a small tennis racket with no strings...slide that up the blue tube and spin it off....Note that the first time I had to change the filter the blue tube was on very tight ,so take your time and be careful....Hope I was able to help.... **Q: Will these cartridges fit the ISpring big blue system that uses the 4.5" x 20" filter cartridge?** A: Yes they will. Cartridge should say in details what size they are. I have used them in mine. Personally tho I feel the original name brand ones are better quality. ## Frequently Bought Together - Express Water Whole House Heavy Metal Water Filter Set – 3 Stage Water Filtration Replacement Kit – Sediment, Carbon Block, KDF High Capacity Cartridge Filters – 5 Micron Water Filter 4.5” x 20” inch - Express Water – 2 Pack Sediment Replacement Filter – Whole House Replacement Water Filter – SED High Capacity Water Filter – 5 Micron Water Filter – 4.5” x 20” inch - Express Water Whole House O-Ring Replacement Kit – 5.5” OD Diameter O-Rings for Filter Housings – 3 O-Rings Pro Seal BPA Free Thermal Resistant O Ring with Lubricant Tube --- ## 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.hr/products/44881487-express-water-fltwh2045cks1-whole-house-heavy-metal-replacment-filter-set](https://www.desertcart.hr/products/44881487-express-water-fltwh2045cks1-whole-house-heavy-metal-replacment-filter-set) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-22*
