1-Year Filter Replacement Kit with RO Membrane for RainSoft 21179 Reverse Osmosis System

INCLUDES:

  • STAGE 1 - 1x Carbon Block Pre Filter (OMB934-5M) - Replace Every 12 Months
  • STAGE 2 - 1x RO Membrane TFC 50 GPD (TFC-RS9-50) - 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 (shown here):
    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.

Perfect for hot summer days
I have purchased 8 pairs of these shorts ★★★★★. Summers where I live have average daily highs of 90° and high humidity. US medium normally fits me perfectly, but I buy 2XL/34-36 in these shorts to keep the fabric away from my skin on hot days. The 34-36 are not baggy and look nice. These short are perfect. Thin stretchy fabric makes them very wearable. Material quality is exactly what I want. The pockets hold everything I want to carry. The price is right.

Pretty nice for a China product!
These are very nice polyester, light weight shorts. Of all the Chinese options on Amazon Ive ever ordered, these are probably the nicest ones. The fit is good, and they're comfortable. Reference- I'm 6', 200lbs, athletic build. I bought size 34.

Comfortable, casual shorts.
These are lightweight with a great fit, perfect for lounging or casual wear. They are also good for light hiking sessions or beachwear. And the price point is well worth picking up a few pairs!
