What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Coway AP-1512HH Mighty
HouseFresh's chamber test rates the Coway AP-1512HH Mighty a strong cleaner — clearing incense smoke in a 728 cu ft lab in 26 minutes at top speed with a 247.7 CFM dust CADR — but flags it as unusually power-hungry (75.3W) and now dated, with better-value rivals available. (1 sourced review, 1 lab-tested.)
Praised: Strong, fast air-cleaning performance (26 min to clear room at top speed) with decent value when the ionizer runs at full speed; Very cheap and widely available OEM/generic replacement filters.
Flagged: Much more power-hungry than similarly performing purifiers (75.3W at Speed 3), raising long-term running cost; Design is dated versus modern units; performance-per-dollar drops sharply without the ionizer and at lower speeds.
Blueair Blue Pure 211i Max
Only one whitelisted tester, Wirecutter, published hands-on measured results for this exact model, naming it their large-room upgrade pick. Wirecutter found it a stellar, quiet, energy-efficient large-room performer (>99.9% smoke reduction), with a durability caveat on the washable fabric cover. (1 sourced review, 1 lab-tested.)
Praised: Stellar large-room particle/smoke reduction (>99.9% in the 30-minute test); Very quiet for its power (<=41 dBA on its four lower speeds); Energy efficient (41 W max; 11-18 W in normal everyday use).
Flagged: Fabric cover looks shaggy over time and lost elasticity after a few washes, needing replacement; Shorter filter replacement cycle (6-9 months vs a typical year); Relatively high price and overkill for small-to-medium rooms.
