R/O Filter Still Ok?

[NorCalFor20]

Had a R/O sytem I used for about two months then disconnected for a faster flow once i realize i get near zero ppms with just the pre evoloution, im wondering if after they sit for a year do they go bad from just sitting or is it ok to reconnect and use now?

I doubt it. I guess you could run it for awhile then check EC, pH. Guy at Marine Depot told me not to buy an RO filter till you need it, because they don't store well. Good luck. -granger
