BREADEEP Faucet Filter Set - 13 Pieces

The PUR FM-3700 is an entry-level faucet filter with NSF 42 and 53 certifications for basic contaminant removal including lead and chlorine. While it has health effects certification (NSF 53), it removes significantly fewer contaminants than the PUR Plus models (about 30 vs 70+). Lacks NSF 401 certification for emerging contaminants like PFAS and pharmaceuticals. Features easy one-click installation and filter change indicator. Good for basic lead protection but not comprehensive filtration.
