RainSoft 21179 Compatible RO Filter Kit - Membrane Sold Separately

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
