Double Cartridge Filters:
Once the filter is opened, it should compulsorily be changed within 6 months even if it is not used. Even when the cartridge filter is not in use, if it is open, it will keep on absorbing contaminants from the environment. If the filter is not opened and is safely stored, they have a shelf life of up to 5 years.
