Swift Green SGF-W01 Rx-3P water filtration 0.5 micron NSF 42 53 401

Certified refrigerator water filter

The Swift Green SGF-W01 Rx-3P is a replacement cartridge certified to NSF/ANSI 42, 53 and 401. It uses a 0.5 micron carbon block to reduce chlorine taste and odour, lead, cysts, mercury, volatile organic compounds and pharmaceuticals. The filter is manufactured in the USA from BPA-free, lead-free and arsenic-free materials. It fits compatible refrigerators as a direct alternative to original branded filters.

Households wanting certified contaminant reduction

This cartridge suits owners of compatible refrigerators who want independently verified reduction of the listed contaminants without removing beneficial minerals. It is not for buyers whose refrigerator uses a different filter model or who require a filtration system certified to standards other than NSF/ANSI 42, 53 and 401.

0.5 micron carbon block with NSF 42 53 401

The 0.5 micron carbon block construction combined with NSF/ANSI 42, 53 and 401 certification is the specification that determines whether this filter matches the required contaminant reduction claims. Compatibility with the specific refrigerator model must also be confirmed before purchase.
