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
