Just a heads up that some of the newer type NP water filters with the screw on type cartridge filter have had the wrong filter supplied in the kit. The correct part no. is on the cap on the bottom of the filter, it should be 420420. If you have a 420422 the you are NOT protected against bacteria and virus.
