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.
The Whirlpool WHERPM RO Membrane WILL NOT fit the Whirlpool WHER12 or WHER18 reverse osmosis systems.
The Whirlpool WHERPM is a 24 Gallon Per Day RO Membrane that comes with installation instructions.
The Whirlpool WHERPM membrane should be changed every 1-3 years based on water quality and usage.
