Brita Faucet Mount vs PUR Faucet Mount
Bottom line
In our scoring the Brita Faucet Mount edges it at 7.0/10 to the PUR Plus Faucet Mount's 6.4/10, and running cost is the whole margin - roughly $0.18 a gallon against $0.25 on identical 100-gallon cartridge life. On certified protection they are close enough that we would let your water decide. The PUR adds certified mercury and pesticide reduction the Brita does not carry; the Brita adds certified VOCs the PUR does not. Both are certified for lead by an accredited body you can look up, which is the thing most faucet filters cannot claim. In our view either is a sound buy: take the PUR if your water report flags mercury or pesticides, and the Brita if you want the cheaper gallon.
Good news first: both of these are genuinely certified, which is more than most of the filter aisle can say. The Brita FF-100 uses the FR-200 cartridge, WQA Gold Seal certified to NSF/ANSI 42, 53 and 401 for chlorine, lead, asbestos, benzene, VOCs and microplastics. The PUR PFM400H uses the RF-9999, NSF certified to those same three standards for chlorine, lead, mercury, asbestos, benzene, pesticides and microplastics. Both are tool-free, both flow at 0.5 gpm, and both cartridges are rated for 100 gallons. The everyday difference is the cartridge price: $17.99 for the Brita against $24.99 for the PUR, which works out to about $0.18 a gallon versus $0.25.

FAQ
- Is the Brita Faucet Mount (FF-100) better than the PUR Plus Faucet Mount (PFM400H)?
- In our scoring the Brita Faucet Mount (FF-100) rates 7.0/10 and the PUR Plus Faucet Mount (PFM400H) 6.4/10. In our scoring the Brita Faucet Mount edges it at 7.0/10 to the PUR Plus Faucet Mount's 6.4/10, and running cost is the whole margin - roughly $0.18 a gallon against $0.25 on identical 100-gallon cartridge life. On certified protection they are close enough that we would let your water decide. The PUR adds certified mercury and pesticide reduction the Brita does not carry; the Brita adds certified VOCs the PUR does not. Both are certified for lead by an accredited body you can look up, which is the thing most faucet filters cannot claim. In our view either is a sound buy: take the PUR if your water report flags mercury or pesticides, and the Brita if you want the cheaper gallon.
- Are both certified to reduce lead?
- Yes, and by accredited bodies you can verify. The Brita FR-200 cartridge holds a WQA Gold Seal certification under NSF/ANSI 53 covering lead; the PUR RF-9999 holds an NSF certification under the same standard. That is a different thing from the 'tested to' language many filters use, which we credit at zero.
- Which is cheaper per gallon?
- The Brita, by about a third. Both cartridges are rated for 100 gallons, so the difference is purely price: $17.99 works out to about $0.18 a gallon against $24.99 and roughly $0.25 for the PUR.
- Do either of these handle PFAS?
- Neither one's certified list includes PFOA or PFOS, so we credit neither for PFAS. That is a statement about what has been certified, not proof that either filter does nothing. If PFAS is your specific reason for filtering, look for a product certified for it under NSF/ANSI 53 - among the pitchers we score, the Brita Elite carries that certification.
