Who should buy which
Founders + healthspan-60 buyers who want set-it-and-forget-it environmental control without the HEPA subscription tax. Apartment biohackers running multiple supplements but ignoring the cheapest mortality-reducing intervention. Anyone in a wildfire-prone region (the no-filter-swap model means unit performance doesn't degrade silently during high-load events).
You have ozone-sensitive asthma (Coway Mighty or Molekule are the safe picks). Or you need a portable unit under $200 (the X3 model at $349 is closer to that price but still above commodity tier, for sub-$200 the IKEA STARKVIND or Levoit Core 300 are reasonable alternatives even though we don't affiliate-cover them).
Homeowners who have run a Tap Score test (or know their municipal water has flagged contaminants) and want to fix the upstream water-quality layer with a permanent RO installation. Also buyers maintaining existing RO systems who need replacement filters at competitive prices.
You are renting and cannot install under-sink hardware (countertop systems work but produce limited volume). Or you have not yet tested your water and might find a $50 carbon pitcher solves your specific contaminant profile.
