The Frizzlife SK99 is the best value under-sink water filter, delivering NSF 42 and 53 certified filtration at just $75 with direct-connect installation that requires no separate faucet or drilling. With 1600-gallon filter capacity, 99% lead removal, and PFAS reduction, this system provides excellent protection at a fraction of premium system costs.
RRenee's take
“I installed the SK99 in our rental before committing to whole-house filtration in our new home. Two minutes of installation, $75 invested, and our water tasted completely different. When we moved, I simply disconnected it and took it with us. This is the filter I recommend to friends who are just starting their filtration journey.”
What we love
- Best value at $75 with NSF 42 and 53 certifications for lead and chlorine
- Direct-connect installation requires no drilling or separate faucet
- 1600-gallon filter capacity means annual replacement versus monthly/biannual
- 2-minute installation is legitimately achievable for most homeowners
Worth knowing
- No NSF P473 PFAS certification - PFAS reduction based on company testing only
- 2 GPM flow is lower than under-sink systems with dedicated faucets
- All cold water from kitchen faucet is filtered - cannot switch to unfiltered
- Limited to cold water only - separate system needed for refrigerator line
