The Whirlpool WHERPM Reverse Osmosis Membrane was originally designed to fit the Premier Reverse Osmosis Unit sold at Lowe's. However this membrane will also fit many standard RO systems including those made by Omni and GE.
This membrane WILL NOT fit the Whirlpool WHER12 or WHER18 reverse osmosis systems.
This 24 GPD membrane comes with installation instructions and adaptor piece. Also known as part number 137856.
This membrane should be changed every 1-3 years based on water quality and usage.
Genuine Whirlpool Replacement part.
