Watch-outs

No significant weaknesses flagged.

Who it is for

· Homes with lead service lines or older plumbing (certified for lead)

What to know before buying

· The Brita faucet system (unit model FF-100) reduces lead and chlorine; its certifications to NSF/ANSI 42 and 53 are held through WQA, the accredited certifier, rather than NSF directly.
· Each filter (cartridge FR-200) lasts about 100 gallons or 4 months, whichever comes first, and the system includes a filter-change indicator.
· It clicks onto a standard faucet without tools; Brita advises running the tap about 5 minutes to prime a new filter, and it does not fit pull-out or sprayer faucets.
