Reverse Osmosis Membrane 50GPD Water Filter Replacement for Reverse Osmosis System 11.75"x1.75" Under Sink RO Drinking Purify for House

Fits great! Water tastes good. Was easy to install and a good value.

We use to have a company come out and replace these but Amazon had the perfect fit filters work great easy to install would 5 star and recommend!!

I haven't used them yet but they look like they should work just fine

Simple replacement of my RO membrane. I do this about every 3 years, and replace my 3 filter set once a year. Its an easy DIY job to save you a bunch of money. One time I had a plumbing company do it, and it was around $150. Its under $50 to DIY it.

This was a direct fit to my iSpring Reverse Osmosis systems. I will test the total disolve solids reading later.

Started with 110 ppm. Changed sediment and carbon filters and reading went down to 70ppm. Changed membrane using this filter. Emptied R.O. 3 times over 36 hours. Reading went up to 360ppm. Put back old membrane and restored to 70ppm. Unfiltered cold water tap is 475 here in Henderson NV.

Fit perfectly
