  • Good fitBest in large bedrooms, dens, and mid-size living roomsRated for 361 sq ft, with a smoke CADR of 233 CFM — enough for rooms up to about 350 sq ft by the two-thirds rule, which delivers the 4–5 air changes per hour allergists recommend.

  • Good fitOdors, pets, and smokeAn activated carbon stage traps the gases a particle filter can't — cooking smells, litter-box odor, VOCs, and wildfire smoke gases.
  • Good fitAllergy and asthma householdsA True HEPA filter captures 99.97% of particles at 0.3 microns — pollen, dander, dust mite debris, and most smoke. Run it continuously for real symptom relief.
  • Good fitSet-and-forget operationListed features include air quality sensor, auto mode, eco mode, timer — handy for letting the purifier manage itself, though none of it replaces CADR headroom.
