The Culligan D-30A water filter reduces extra fine dirt, sand, sediment, silt, rust particles, and turbidity. The Culligan D-30A water filter cartridge fits in undersink water filter systems. The Culligan D-30A water filter is tested and certified by NSF International to NSF/ANSI Standard 42/53 in model US-600A and US-600 which means that the Culligan D-30A replacement filter has passed rigorous testing standards. The Culligan D-30A is recommended for use with city and well water supplies.

Note: Culligan has changed the model number of this filter from D-30 to D-30A due to a design change. The contaminant reduction remains the same. The D-30A has a flow restrictor which will reduce the flow rate more than the original D-30. The original D-30 is no longer being manufactured.

  1. The Culligan D-30A under sink water filter life is up to 12 months or 1000 gallons (depending on the quality of your water)
  2. The Culligan D-30A should be installed with the end of the filter with the hole facing up
  3. If no water is passing through the system, the filter is likely installed upside down
  4. If the flow restriction in the Culligan D-30A is too great, you can increase the flow rate by drilling a larger hole where the existing hole is, with a 1/8-inch drill bit
