Re: The cheapest RO membrane on market

I am trying to find the smallest and cheapest membrane w/housing (same dimensions of course). I was thinking of using a high pressure washer as my pump - with does things in place I basically have a water maker.... but will add sediment filters pre membrane (20 and 5 micron), psi gauge and one-way vales.

As stated in my last post, the smallest sea water membrane I have found is 2.5" x 21".. But the 2.5" x 21" housing I found only handled 300 psi. I thought the latter might be meant for brakish water. Maybe I have misunderstood how pressure works.

Thanks for your reply and link coleMJ.. Will definitely look into the company!

The company you suggested was exactly what I was looking for!! They have 2.5" x 21" membrane and high pressure vessel in the same size. Now, I just need to cross my fingers they ship internationally for a good price.
