The PUR FM-3333B Faucet Water Filter System is a 2-stage white plastic vertical faucet mount filter system. This PUR faucet filter snaps on to your sink faucet with one easy click. The PUR FM-3333B comes with one 2-stage PUR faucet filter (RF-3375) which removes or reduces lead, mercury, sediment, dirt, the bad taste and odor of chlorine, and numerous other harmful impurities and contaminants.
The PUR FM-3333B faucet system is a tilt up design which can be installed easily and quickly without tools. Using a bypass feature, this PUR faucet filter allows you to switch between filtered and unfiltered water for drinking, cooking, and so on. The built-in filter life indicator reminds you when it is time to replace the filter.
The replacement filter for the PUR FM-3333B faucet filter system is the 2-Stage RF-3375, though it can also use the 3-Stage PUR RF-9999 filter. The RF-9999 faucet water filter is more advanced and removes more impurities and contaminants. Both the PUR RF-9999 and PUR RF-3375 work for up to 100 gallons or about 2-3 months before needing to be replaced.
