Frizzlife SK99: The Countertop RO Option
The Frizzlife SK99 ($200--$280) is a countertop tankless RO -- it sits on the countertop rather than under the sink and connects via an adapter to a standard kitchen faucet aerator. No dedicated faucet, no drilling, no permanent installation. For renters or households who do not want any under-sink modifications, the SK99 provides the same filtered water quality as the PD400 in a fully reversible countertop format. RO water output through the SK99's own faucet spout; tap water continues through the kitchen faucet as normal via the diverter valve.
