Housings hold and protect filters in multi-stage purification systems. If the housing on your pure water system gets cracked or damaged, you can easily pick up a new one at WCR. In addition to housings we also carry RO Membranes, Carbon & Sediment Filters and DI Resin. Check out the entire selection of Replacement Filters for your system to keep it working like new. XERO, Tucker, IPC Eagle, and Unger are just a few of the industry leading filtration brands. Want to learn more about pure water systems? Check out our free Understanding Purification guide.
