Works fine in my KitchenAid refrigerator. Water does seem much better filtered compared to before, though I had left the old filter in considerably longer than I should because I forgot about it and the replace filter light never came on.
Based on the product packaging, this filter really is rated as NSF 53 (and not just unofficially claiming to filter 53 contaminants).
