    This worked perfectly to upgrade my RO Buddie from 50GPD to 100GPD. My only issue was the seal was attached about two inches from where the OEM seal was situated. I removed the tape, slid the seal up, put the tape back on. I’m not certain this is required but did it anyways. If the filters are going to be shipped out like this, maybe the filter photo could be updated to reflect the placement.

    I returned this membrane because when it I received it, it was the original membrane and appeared to be a knock off. I did not spend $51 on a cheap knock off. I can go elsewhere and spend $30 if thats what I wanted. Beware, this is not the same as what came with the system and is much more expensive than other replacement membranes on Amazon.

    Just wish these would last longer, or have a longer per gallon output longevity for the price.

RO Buddie & Classic Models

This membrane fits standard residential reverse osmosis units, including the RO Buddie and Aquatic Life Classic 100 GPD RO/DI unit. Use two of the 100 GPD Membranes in the Aquatic Life 200 GPD Hydroponics RO unit.

Industry Standard Membrane Sizes

The 50 GPD Membrane is an industry standard 1812-50 size and the 100 GPD Membrane is a 2012-100 size. Both sizes are rated for ideal pressure of 65 PSI and water temperature at 77°F.

Up to 98% TDS Reduction

With up to 98% reduction in the supply water TDS, these membranes provide quality filtered water. In applications where zero TDS is desired, you will use less DI mixed-bed resin because the membrane will be removing more of the TDS.

Operating Temperature

The membranes will work with water temperatures between 50 and 100 °F. Supply water below 77°F will produce less filtered water while temperatures above 77°F will produce more filtered water.

Operating Pressure

The membranes will work with water pressure between 40 and 100 PSI. Supply water pressure below 65 PSI will produce less filtered water. Supply water pressure above 65 PSI will produce more filtered water.

Total Dissolved Solids Reduction

The RO membrane reduces impurities known as total dissolved solids (TDS) from the water

down to 1/10,000 of a micron.
