Who the Smart Air Blast Mk II is for

Good fitBedrooms and light sleepersAt 29 dB on its lowest setting, the Smart Air Blast Mk II clears the 30 dB bedroom bar — roughly a whisper.
Keep in mindParticles only, not odorsWithout a substantial activated carbon stage, the Smart Air Blast Mk II won't do much for cooking smells, pet odor, or smoke gases — it handles particles like dust, pollen, and dander.
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.
Keep in mindCADR is self-reportedThe Smart Air Blast Mk II isn't AHAM Verifide, so its CADR and coverage figures come from the manufacturer rather than an independent lab — treat them as a ceiling, not a promise.
