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).
A bedroom or office up to about 258 square feet where you want standards-grade HEPA filtration with automatic operation, from a brand whose parts and filters will still be purchasable in a decade.
You need whole-home coverage, in which case a ducted or multi-unit approach beats any single tower; you want a comparable CADR number before buying, which Vornado does not publish; or the recurring cost of HEPA and carbon replacements is the thing you are optimising away, which is Airdog’s washable-plate argument.
