Product review (1 stars): FALSE ADVERTISEMENT!
This does NOT have NSF/ANSI 53 rating like the description says it does!

NSF 42 removes non-health-related contaminants such as chlorine, taste and odor, and particulates.
NSF 53 reduces a significant amount of a specific harmful contaminants from drinking water. Such hazardous contaminants may be microbiological (including filterable cysts), chemical (including disinfection byproducts, pesticides, herbicides, and insecticides), or particulate in nature.
This information is from the NSF website.

Don't let these people get you in to buying a filter that doesn't have the rating they say it does.
