A whole-house KDF and catalytic carbon filter that SpringWell guarantees keeps chlorine and chloramine below detection for 6 years or 1 million gallons, at 9 gpm.
The catch: No certifier we checked lists it, so the guarantee is SpringWell’s alone.

Our verdict
The SpringWell CF1 is a point-of-entry filter: it goes where water enters the house, so every faucet, shower and appliance gets filtered water. Water passes a 5-micron sediment filter, then KDF (a copper-zinc media) and catalytic carbon. SpringWell rates the media for 10 years or 1 million gallons, and guarantees that it keeps chlorine and chloramine below detection limits for 6 years or 1 million gallons.
The problem is that none of this is certified. NSF International, WQA and IAPMO R&T don’t list the CF1, and SpringWell doesn’t publish a lab report on its product page. Without a certified or lab-tested claim, our scoring puts it at the floor for contaminant reduction, which is why it scores well below certified filters despite low running costs and an easy life once it’s installed. If you want chlorine taste gone from every tap and you trust the guarantee, it does that job. If you want certified lead or PFAS reduction, filter your drinking water separately with a certified filter. Our NSF certification guide explains how to check a certifier’s listing yourself.
You’re on city water and want chlorine and chloramine taste and smell gone from every tap, including showers, with almost no upkeep.
You want certified reduction of anything, or you need hard water softened.

Common questions
Is the SpringWell CF1 certified?
Not by any certifier we checked. NSF International, WQA and IAPMO R&T list no SpringWell system. SpringWell says it uses “certified components” but doesn’t say which, or who certified them. Its chlorine and chloramine guarantee is SpringWell’s own.
Does it remove lead or PFAS?
It isn’t certified for either. For certified reduction at your drinking-water tap, see the Epic Smart Shield (lead) or the AquaTru Carafe (lead, fluoride and PFOA/PFOS). See our lead guide and PFAS guide.
Does it soften water?
No. It’s a carbon filter, not a softener, so it won’t stop scale. SpringWell sells the FutureSoft conditioner for that.
How long does the media last?
SpringWell rates it for 10 years or 1 million gallons, and guarantees its chlorine and chloramine performance for 6 years or 1 million gallons. The 5-micron sediment filter needs changing more often.
The bottom line
The CF1 is a low-upkeep way to take chlorine and chloramine taste out of every tap, backed by SpringWell’s guarantee rather than a certification. Buy it for that, on city water. For certified lead or PFAS reduction, add a certified drinking-water filter like the Epic Smart Shield or the AquaTru Carafe. Compare options in our whole-house guide.
