1-Year Filter Replacement Kit for RainSoft 21179 Reverse Osmosis System (RO Membrane Sold Separately)

INCLUDES:

  • STAGE 1 - 1x Carbon Block Pre Filter (OMB934-5M) - Replace Every 12 Months
  • STAGE 2 - 0x (RO Membrane TFC-RS9-50 Sold Separately or Included with Replacement Kit YSM-RS21179) - Replace Every 24 Months
  • STAGE 3 - 1x Carbon Block Post Filter (OMB934-1M) - Replace Every 12 Months

Note these filters are high-quality replacement filters for the Rainsoft 21179 RO system and not genuine Rainsoft parts.

Note: If your Rainsoft reverse osmosis system is from 2013 or newer, it most likely is the Ultrefiner II. The Ultrefiner II requires proprietary filters that must be purchased from a Rainsoft dealer. Conversion kits to generic non-OEM replacement filters are available.

We offer two replacement filter kits so you can get exactly what you need — and avoid paying for filters you don’t.

  • Year 1 Kit (Includes RO Membrane):
    Ideal for your first full replacement, this kit includes all filters plus the RO membrane, which typically lasts up to 24 months.

  • Year 2 Kit found on this page (Without RO Membrane):
    After the first year, you only need to replace the pre- and post-filters, since the RO membrane is still good for another year. This kit helps you save money while keeping your system performing like new.

*Filters may need to be replaced more often than indicated, depending on incoming water contaminant levels and volume of water being treated

Our pups' absolute favorites!
Size: 9 Count (Pack of 1), Size: 9 Count (Pack of 1)
Our two little rescue dogs Molly and Layla are very, very, very picky. However, these lamb strips are their ABSOLUTELY favorite treat. They have other favorites, but sometimes aren't in the mood for one or another. But this one-- never! If they see the bag, but I try to give them something else, they both just look at me as if to say, "Forget that. Give us the really good stuff, Mom!" They aren't cheap. So, I ration them out. It's not a daily thing. That keeps them special, too. Here they are in the photo, waiting patiently to get one of these lamb strips from me.
