The filters that came with your Aquasafe RO/DI unit are made by Dow, as well as the FilmTec. Now we are talking about the ro/di filter itself the one that will determine your waste water %. Both of these filters are tested @ 50 psi(so much for lower pressures) and a norm for house pressures are about 20-25psi, but can be lower. As with all ro/di filters they sell a booster pump or even better a
Permeate Pump (needs no power) to increase the efficiency of your filter. All of the filters will work better (less waste water) at a higher pressure (the more water you can push through the better it filters).
The longevity of your filters is in the amount of water used and the starting TDS(amount it needs to filter). I change my filters about every 18 months when the TDS goes from 0 to about 2. using a ton of water for top-up, water changes and drinking as well as ice. So...so much for craping out...... What you need to know is a flush once in a while helps to maintain your filters.
But I bet you can buy FilmTec at Gold's.
To replace your filters....
I saw what your looking for on E-Bay but I would think there should be someplace closer.
