APPLIED MEMBRANES Reverse Osmosis Membrane and Filter Replacement, 50 GPD Membrane with Pre and Post Filter, Complete RO Filter Set and Membrane for 5-Stage Water Filtration Systems

I titled this (no problems yet) because it’s only been like three months that we’ve replaced these. Skeptical because the system is atleast 10yrs old, and we couldn’t find the exact filters anymore, so after extensive research these were the closest to our system we could find, and we wanted to take a chance at changing the filters one more time to determine if it was time for a new system. Well so far we’re keeping our old system, the water flows great, water is clean and taste fresh. If in the next three months it continues the same , I would have no problem buying these filters again.

I installed these filters when my RO was not as efficient as it should be (< 20%). My tap water here is 880ppm. After installing these replacement filters my RO water was 30ppm. It's good. Note that I use a smaller flow restrictor knowing it can foul the membrane faster but I only waste about two gallons per gallon of clean water. I reverse flow to rinse my membrane once a month and they last 2 years still. I contacted GEEKPURE to ask what size flow restrictor to use and they responded quickly but it was a boiler plate template that didn't answer my question with a number of ml/min. I will buy these again!

Worked perfectly for 20-year old Eden Filters RO system.

I used this to replace my Nugen RO system filters. It went smooth until the 5th filter. I had 3/8" tubing with a 1/4" hole. I ran to ACE Hardware and got the appropriate connectors. I am docking 1 star for not having a trouble shooting section on the instructions.

Muy buen producto la calidad excelente

I have not tried them yet, but they looked exactly like the factory ones that came with the water system. These are approximately 1/2 the price.

Just install them in a customer's home don't know how the water tastes cuz I don't live there

We have been ordering these membranes for a number of years. They keep our drinking/cooking water as best tasting water, fresh, cool and clean. We order them twice a year and one can definitely taste the difference. They are easy to install. Keeping our drinking water clean!
