NSF certification
The MK99 isn't listed in NSF's database - this brand certifies through WQA or its own testing, not through an NSF DWTU listing we can independently cite. That isn't proof it doesn't filter well, only that we can't verify a specific contaminant-reduction claim for it here.

Frequently asked
What replacement filters fit a Frizzlife MK99?
The Frizzlife MK99 uses 1 filter stage: FZ-2.
Is the Frizzlife MK99 NSF certified?
The Frizzlife MK99 isn't listed in the NSF Drinking Water Treatment Units database as of our last check. That doesn't necessarily mean it doesn't filter well - this brand may certify through WQA or its own in-house testing instead. We only claim an NSF reduction when it's independently NSF-listed.
Does the Frizzlife MK99 remove lead?
We don't have an independent NSF listing for the Frizzlife MK99, so we can't confirm a lead-reduction claim either way. Check the manufacturer's own certification documents.
Should I buy the genuine filter set or an aftermarket one?
The genuine Frizzlife cartridges are the safe, exact-fit choice. A cheaper compatible set can fit the same housings too - just confirm it carries its own independent certification for the contaminants you care about before buying.
