About This

• Universal Compatibility & DIY: The Purevua PWB20 whole house water filter housing features high-flow 1" NPT brass threaded ports and fits all 20" x 4.5" filter cartridges, allowing you to choose the ideal cartridge type for your needs. You can also connect multiple standard housings or other water filtration equipment in series, combining sediment, activated carbon, and other cartridges to build your own DIY whole house water filtration system.
• Enhanced Sealing & Original O-Rings Available: Our under sink filter housing utilizes brass threaded inserts and a double O-ring sealing design for higher pressure resistance and a tighter fit, effectively eliminating leaks. Since many products on the market do not include original O-rings and mismatched replacements often cause leaks, we continue to offer original O-rings for sale to ensure safe, long-term use. For O-ring accessories – please check further down this page or search ASIN B0FBX99TPD on Amazon.
• Premium Materials & Water Safety: Constructed from high-quality reinforced polypropylene with an extra-thick build, our water filter housing delivers superior corrosion resistance and pressure tolerance, ensuring longer service life and stable performance even in high-pressure or harsh conditions. The material is food-grade, complies with NSF standards, and is BPA-free, lead-free, non-toxic, and odorless, providing your entire family with a safe and clean water environment.
• Easy Installation & Maintenance: The Inline housing kit includes everything needed for mounting – 1 heavy-duty steel mounting bracket, 1 dedicated wrench, 1 roll of teflon (PTFE) tape(6 meters / 19.69 feet), and 4 screws – making installation straightforward. A pressure relief button on top allows you to release trapped air or internal vacuum pressure before unscrewing the bottom, making cartridge replacement and routine maintenance safer and easier.
• Note: 1. Product dimensions are 23.5" x 7"; Please carefully consider the space required for installation and future cartridge changes before purchasing. 2. Do not over-wrap Teflon (PTFE) tape during installation. 3. Filter cartridges are sold separately.
