Product review (4 stars): Good charcoal filter - does not remove lead and other contaminates
Great replacement filters. Knocked off 1 star because they are only charcoal filters and do not remove lead and other chemicals like the more expensive original filters. Not 100% sure of the numbers - but these are 42 compliant where the original is 42 & 53 compliant. (Those numbers may not be correct - but not taking the time writing this to go check.)

I think they are made in China... another ding. But, they fit, they remove odors and any bad taste .... and are much cheaper than original 42 & 53 compliant filters.
