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 on chlorinated municipal or hard well water who want filtered water at every tap - shower, skin, hair, laundry - not just the drinking glass. Pairs cleanly with an under-sink RO for drinking water to cover both the point-of-entry and point-of-use layers.
You are renting and cannot plumb the main water line (an under-sink RO is the right tier for you instead). Or you only care about drinking-water quality - a point-of-use RO is cheaper and sufficient for that single job.
