Where do you buy your RO/DI filters?

Ive bought from air water ice for the past dozen years but they are so expensive. I have a 5 stage including the membrane. Where do you buy from? Anyone buy direct from Amazon?

You can buy from anywhere but have to watch the micron ratings.
Just bought a membrane other than from regular supplier & it does not appear to be as good.

True. Id also be interested in knowing what others use. Besides the DI and the membrane. I use a 1,5 and 10 micron

I use .5 micron sediment and .5 micron carbon block. You should change these every 6 months. They protect the membrane. I also get them from BRS.

I'm not saying I'm Batman. I'm just saying nobody has ever seen me and Batman in a room together.

Current Tank Info: 80 gallon rimless Deep Blue lagoon
