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

Sturdy rubber ball. Noise maker could be improved
Color: Red
I would have given it five stars because of how much, my dog loved it in the beginning. And shut us up holds true as a sturdy rubber ball. My only complaint is at with one of my dogs being a heavy chewer, she was able to bust the noise making part. The ball never broke open or anything. It just no longer makes noise. You can hear the piece rattling on the inside. The ball itself is still solid tho

POOR QUALITY WHILE OVER PRICED
Color: Brown
Like so many others said, the sound box in this ball is faulty. lasted ONLY for 30seconds. My dog loves the giggle ball I purchased prior so I knew she would like this as well. Well, she did, for that whole 30 seconds. Both of us were so disappointed we could not further our play. Plus this ball was so much smaller than expected for the cost. I would not have minded the cost had this ball been on the ball! Don't purchase this item. Buy the giggle ball instead if you haven't already. UPDATE... Ran across this message at a later date and I would like to thank the sellers at Mewlmart for their response and showing the best business practices as stated in their response below. ----------------------- We sincerely apologize for any inconvenience regarding your order and would like to offer you a full refund for your purchase. If you would like a full refund: please reply 'Full refund'. We hope that you give us another chance. Thank you very much. Best regards, Mewlmart ----------------------- Only thing is I wish I had seen their message earlier, as I believe the window of opportunity for a refund may no longer be applicable. But who knows, they may reach out and still honor it when they review this review. Will update if that happens as it is worth mentioning the extra mile they may take. I am sure I would just then turn around and buy another product from them, giving them another try:)
