TFC-RS9-22 Reverse Osmosis Membrane

Purchased this filter from you in 2015 and was surprised that it had to replace so quickly. Have replaced this old filter about a week ago that I again got from you and hoping to get more use out of this replacement. Just to let you know the original that came with the under sink system lasted at least 4 years!

Thank you for a cost-effective replacement for an expensive membrane filter. The prevuownwra has already voided the warranty with bad replacement filters, so it was a no-brained for me to buy a replacement membrane at a fraction of the OEM price. Fit perfectly and works to keep my water crystal clear and fresh tasting.

It is alot thinner than the original Rainsoft filter that came with the sysyem. The tds is still in the mid 150's, I believe it should be in the below 50 but I am not an expert. It is waaaay cheaper than the rainsoft filter though.

The Rainsoft Membrane was an exact fit and exactly what I needed, the process for ordering was easy and the product shipped quickly and arrived on time... would definitely recommend.

This product does not fit my Rain Soft Purerator 2. Three stage only reverse osmossis. System.

Works good

Fit well and much cheaper than the Service Company prices

Looked simular to the factory cartridge, but diameters were wrong to fit and seal to the manifold.
