Does the filter stop automatically once the tank is filled?

Yes, once the tank is full and pressurized to its maximum, the filter automatically stops filtering and storing more water. Once water exits the tank for use, and space is created, the filter starts working again.

How often should the filters be changed?

Filters of stages 1,2,3 should be changed periodically between 6-12 months. The stage 4 membranous filter and the stage 5 polishing filter can be changed once every 2-3 years. This is an estimated amount that depends on the contaminant level in your water supply. If you feel chlorine levels run high in your area, then changing filters 1,2,3 will retain your filter 4 for a longer period.

Is there a need to clean the tank regularly?

No, the tank does not require regular cleaning. If you feel the system has not been in use for a long time, you can clean the tank, and even then flushing it once would be more than enough.
