1-Year Filter Replacement Kit with RO Membrane for RainSoft UF22 Reverse Osmosis System

INCLUDES:

  • STAGE 1 - 1x Carbon Block Pre Filter (OMB934-5M) - Replace Every 12 Months
  • STAGE 2 - 1x RO Membrane TFC 22 GPD (TFC-RS9-22) - Replace every 24 months
  • STAGE 3 - 1x Carbon Block Post Filter (OMB934-5M) - Replace Every 12 Months

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 found on this page (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 (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 water contaminant levels and volume of water being treated.

My picky dog loves them.
Size: 3.5 Ounce (Pack of 2), Style: Chicken Chips, Size: 3.5 Ounce (Pack of 2), Style: Chicken Chips
I try to give my dog, whom I love so much, the healthies food and treats that i can. She is so very picky and it's difficult to find things she likes. She loves these treats and expectes one every morning. She litterally waites by the pantry door for one. The are healthy Human grate chicken chips. Makes me feel better about giving her a treat. I would Highly recommend.
