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.
