Help figuring our RO system and needed filters

[anonymouse]

I just recently bought a new home that has a Rainsoft RO system that is about 2 years old. I need to replace the filters, and the alarms state that they have not been replaced yet. The manual shows that it is a Ultrefiner II-FMV. The Rainsoft part numbers for the filters are 51635 (Pre-filter), 51637 (Membrane), and 51636 (Post-filter). I am looking for compatible filters, but cannot find any corresponding compatible filters based on these part numbers, but then again, Rainsoft part numbers seem very ambiguous (I'm sure purposefully), based on my searches so far. Any help with this would be appreciated!

And on another separate note, does anyone know if there are re-mineralization cartridges available for this system? I am worried about lacking minerals in our drinking water.

First off, minerals in your drinking water do not account for any significant number of your daily intake. In short, if you're counting on your water to get minerals...you're doing it wrong. That's not the role of water in your body. Second, Rainsoft is generally a proprietary brand. You will more than likely have to call your local dealer and get the filters from them. Ask about a mineral cartridge option. I've seen third party options in the past that go inline after the RO that look like a TCR filter. Other RO's such as the K5 from Kinetico have an optional filter slot to add one on. But, again...the mineral thing is a non-issue. You would have to drink more gallons of water a day than is humanly possible to get any sort of mineral benefit from your water. I forget the number. But, it's a big one. I'd have to go back and look it up. Best of luck with the filters!
