I have a 5 stage RO DI unit and all the filters need replaced. Like a lot of people these days, I have to stretch every nickle. Anyone know who has a good deal on a good product?

I wouldn't skimp on the actual membrane (( just try to find the best price for a good one )). I would look for the Dow Filmtec 75 GDP one. It has a 96-98 rejection rate, so while it will cost a bit more now, it will pay off in the long run --- with a higher rejection rate you will go through your DI resin slower.

I would look for a Filmtec and see what store has the best price on that brand. IMO those membranes are the best in the industry. FWIW that membrane should only need replacing every 3-5 years if properly kept.
