• The recommended replacement schedule for the Culligan D-40A cartridge is every 6 months or after 600 gallons of usage, whichever comes first. Factors that determine when the cartridge needs to be replaced include a noticeable decrease in water flow rate, a change in taste or odor of the filtered water, or the presence of visible sediment in the filtered water.
