Works great and a lot cheaper than buying it from a professional window cleaning store
These are great to use for helping improve the purity of water. It essentially helps purify the water down to 90 or 95% purity which is fantastic and it lasts you forever. We’ve only bought it this year so we don’t know how long it last but if you take good care of it, it should last a good five maybe seven years.

Garbage membrane
Installed this membrane and right out of the package it would not produce any permeate. Membrane was installed as per RO systems instructions. Spoke to systems manufacturer and was told membrane was defective. Emailed RO membrane distributor and they were very quick to point fingers as to it not been the membrane. The water this membrane is allowing through is still full of iron and very hard. Would not recommend this product or the distributor as they don’t stand behind there product

Lasted Less Than 30 Days
We used this as replacement membrane in on whole house RO system and it failed in less than a month. Previous membranes have lasted a year or more. Support tried to blame our system until we sent them our setup and then they said there is no warranty because of a "high likelihood of factory failure"
