    Membranes Short life
  

*by M***O on Reviewed in the United States on December 9, 2021*

They only last about 3 months then the water flow slows significantly. Although they are much cheaper than the hydro-logic 300 RO replacements. I’ve used both and the life on them are exactly the same. This garbage that the water is dirty and that’s the reason of its short life is simply not true. The manufacturers on both membranes replacement systems just like overselling there products. If there is truly a Warrenty for there life, I would challenge all of it!

    Big improvement
  

*by A***S on Reviewed in the United States on August 19, 2023*

I didn’t realize how old my RO filters were. Checked the TDS at around 100 after filtration and ~325 before. I thought this was fine. Got an ad for these replacements and thought it was probably time to do it but I didn’t expect a change. I was wrong - TDS between 8-12 after the swap and the flow rate was noticeably faster.

    Great Value
  

*by R***S on Reviewed in the United States on May 7, 2021*

I run a pair of 50 GPD RO membranes in parallel in a modified Watts Zero Waste system.  I used other budget membranes before but they didn't last very long before restricting the flow to the point my pump broke.  I used Watts membranes for about a year and they still flowed well but the TDS readings started to creep up to around 18.  Just put these in and they started out with about 300 TDS which is normal.  I ran 5 gallons though them and the TDS fell down to 6 on one and 8 on the other.  So far so good.
