What containers are safe for RO water?


New member
Well I have posted this elsewhere and I have not gotten any answers except for what I already know. I know that Rubbermaid Brute containers are safe but I do not want a 40-55g can in my laundry room. I would like a 20g or so container that is tall and slim. Any suggestions as to what kind of container is safe?

Rubbermade makes different size food grade containers you can get at a good restaurant supply store. When I first started out, I bought a nice white one that was about 20 gallons.

Best of luck,

Any that says it is made of polyethylene (PE, LDPE, HDPE, , etc) or polypropylene (PP) is fine. So are many other plastics. :)

Just be sure it doesn't claim to be treated to resist mildew, odors, mold, etc.
