Kent Maxima Hi-S left sitting

[jond]

I moved back in November and had replaced all of my filters shortly before that except for the membrane. Since moving, I have not got around to hooking it up again and so it has just been sitting in the garage.
My question is, can I use it again after running some water thru it, or do I need to replace filters? And if so, which ones? Is the membrane still good?
Thanks for any help.

If the membrane was just sitting around then it's ruined and needs to be replaced. The prefilters should be fine.

Thanks for the advice. That is what I was afraid of though.
