kent maxxima?

I can't remember if the membrane states it or not but a rough way is to see how many gallons it produces in an hour and then multiply by 24 if its over 35 it's probably the 60gpd model. I'm not positive but you may even be able to use either filter in the unit. As for the other filters the Kent replacement schedule is 6 months for the particulate and charcoal filters and for the DI change when the color change is 1" from the top of the canister. RO filter is 3-5 years.
