CFSCOMPLETE FILTRATION SERVICES - 1-Year Replacement Filter Kit with Membrane for RainSoft UF50 Reverse Osmosis System -

Water tastes the same but the price is about 30% less. Haven't had the water tested yet, but judging by clarity and taste, I won't be going back to the scalpers at Rainsoft.

This does not work for the Rainsoft Ultrafiner RO system (UF50). The RO filter is missing the plastic nipple on the bottom end that keeps the filter seated properly. Without it the RO filter pops out of the connection under pressure and you get no RO filtration and higher pressure than normal. These clearly will not work with the system and the seller is in bad faith.

This was a perfect replacement for my Rainsoft RO system! Easy to install, no leaks, and ppms are down to zero! And no big bills from the Rainsoft service people Enchanted Waters!

Works great for replacement for our reverse osmosis system.

Good value for the money. Came in fast, packaged well. Second time I've ordered this. Pleased with results.

Perfect Rainsoft Replacements. Very easy to install. Just don't forget to shut off the water first. And no I didn't forget. :o)

I searched for a replacement filter set for the rainsoft system according to amazon or the seller this set was supposed to fit, well none of the three fit on the rainsoft system. Waste of money.

This product was an exact fit for my Rainsoft RO unit.

The membrane does not fit, the nipple at the bottom is missing and does not set well. The other two filters is okay.
