Frizzlife makes two types of under-sink systems: RO (removes dissolved contaminants including fluoride) and non-RO carbon filters (removes chlorine and improves taste only). Here's which one to choose.
The Frizzlife SK99 is a popular under-sink 3-stage carbon filter. It improves taste and removes chlorine, but it is NOT reverse osmosis. It does not remove fluoride, nitrates, heavy metals, or PFAS. If you have specific contamination concerns, you need the PD600 RO system.
600 GPD tankless under-sink reverse osmosis. Removes 1,000+ contaminants including fluoride, lead, arsenic, PFAS, and nitrates. NSF 58 certified. Requires electricity and a drain connection. Best for households with genuine water quality concerns.
3-stage under-sink carbon filtration. Removes chlorine, chloramine, bad taste, and some heavy metals. Does NOT require electricity. Much cheaper upfront. Best for households with clean source water who just want better-tasting water.
