I need a replacement RO membrane. I have seen the Filmtec models at several on line sites. Salty Supply has one that is 100 GPD for around $40. That seems cheap? I have heard the higher volume ones are not as efficient? I think the rejection rate on the Dow Filmtec is 90%
It seems like the models that produce less water per day are more efficient?
The Spectrapure seem much more expensive, is there anything comparable that is cheaper?
Also, shoud I be using the 1 or .5 micron pre-filter and carbon block?
Thanks.
