### ⭐⭐⭐ 







  
  
    Replaced in 2015 and again in 2017
  

*by K***R on Reviewed in the United States on April 17, 2017*

Purchased this filter from you in 2015 and was surprised that it had to replace so quickly.  Have replaced this old filter about a week ago that I again got from you and hoping to get  more use out of this replacement. Just to let you know the original that came with the under sink system lasted at least 4 years!

### ⭐⭐⭐⭐⭐ 







  
  
    Fit perfectly
  

*by O***E on Reviewed in the United States on March 29, 2018*

Thank you for a cost-effective replacement for an expensive membrane filter. The prevuownwra has already voided the warranty with bad replacement filters, so it was a no-brained for me to buy a replacement membrane at a fraction of the OEM price. Fit perfectly and works to keep my water crystal clear and fresh tasting.

*by R***S on Reviewed in the United States on September 30, 2017*

It is alot thinner than the original Rainsoft filter that came with the sysyem. The tds is still in the mid 150's, I believe it should be in the below 50 but I am not an expert. It is waaaay cheaper than the rainsoft filter though.
