Whirlpool — WHEERM Reverse Osmosis Replacement Membrane NSF Certified Contaminant Removal Our WHEERM Reverse Osmosis Replacement Membrane fits our most advanced filtration systems that meet the requirements set by the National Sanitation Foundation (NSF). The NSF Standard for water filtration systems requires devices to reduce up to 15 contaminants that are commonly found in drinking water. This means our filtration systems are certified to remove contaminants such as copper, cysts, lead, sodium and chloride. How Does Reverse Osmosis Work? Reverse osmosis filtration works by applying high pressure to the water source, forcing pre-filtered water through a semipermeable membrane at a high rate leaving dissolved contaminants behind. The water then goes through another filter and is stored in a tank before coming through your home’s faucet cleaner than ever before. you need to change the system’s filters and membrane regularly. You can start by replacing your filters twice per year to ensure your system is working correctly. The membrane can last four times longer than the filters, but that depends on the condition of your water before it goes through the filtration system. Highly contaminated water will require more frequent membrane and filter changes. Simple Membrane Replacement The UltraEase Filter & Membrane Replacement system does not require you to shut your water off. Simply turn the membrane a quarter turn and it will release. Replace it with a new membrane, and reverse the quarter turn until the membrane clicks into place. Designed for use with municipal and private well water supplies.

It fit my Dupure RO system.My Dupure RO system was discontinued and looked just like this one. It fit! Works fine. I ordered the filters and they didn’t fit😥. But I had 2 of my Dupure new filters so will change my system to Whirlpool when these are old. Dupure wanted $900 for a new system.

Perfect RO replacement filtersThese are exactly the correct replacement filters for my WHER25 Under sink Whirlpool RO system. After installation my TDS (Total Dissolved Solids) is down to 14 for the RO water vs. 195 for the untreated tap water.
