Pros & Cons
What We Like
- Removes 84 NSF-certified contaminants including PFAS, lead, and fluoride
- True 4-stage reverse osmosis — the most thorough filtration available
- No plumbing or installation required — plug in and pour
- Removes viruses, bacteria, and protozoa without chemicals or UV
- 0.75-gallon clean tank provides drinking water on demand
Watch Out For
- $450+ upfront cost is the highest in the water filtration category
- Requires electricity — not suitable for off-grid without power
- 16.3 lbs is not portable — countertop only
- RO wastes water — produces brine that must be discarded
- Replacement filters add $60-80/year in ongoing cost
