## Customer Reviews

### ⭐⭐ 







  
  
    Didn’t fit my Rainsoft
  

*by J***R on Reviewed in the United States on January 31, 2021*

Good and well built. Material seemed to match my Rainsoft ro. However the filter did not fit. It didn't fit due to a yellow nib at the bottom of the original rainsoft membrane. This missing piece did not allow the unit to house snug, causing water to pass around the filter

### ⭐⭐⭐⭐ 







  
  
    It fits my rainsoft RO system and seems to do the job...
  

*by O***E on Reviewed in the United States on January 23, 2020*

It was a drop-in replacement for the original membrane. The only issue after changing it at the same time as the filters was the amount of air in the system took some time to purge. I had to utilise bypass mode several times over the first month to purge the air.

### ⭐⭐⭐⭐ 







  
  
    Not quite same fit as Rainsoft but I’ll likely order again.
  

*by T***N on Reviewed in the United States on September 6, 2019*

I think it’ll work, it didn’t fit exactly right.  That being said, Rainsoft gouges their customers for these and wanted $150.  That and their archaic process of picking up a phone to a dealer will make me order this next time.
