Pros & Cons
What We Like
- Reverse-osmosis membrane certified to remove 84 contaminants, including PFAS
- Under-sink install keeps the counter clear versus the countertop AquaTru
- Smart leak detection guards against under-cabinet water damage
- RO-grade filtration handles well water and municipal supplies alike
- Dedicated faucet delivers on-demand purified water for the whole household
Watch Out For
- $395 ($420 alkaline) is a significant outlay versus pitcher and gravity filters
- Requires under-sink installation and a dedicated faucet, unlike a countertop unit
- RO systems produce brine wastewater during filtration
- New 2026 second-generation release — limited long-term owner reviews at launch
