PM2.5
AeraSense sensing technology
accurately detects and quickly
responds to even the slightest
particle change in the air. It provides
you with reassurance with real-time
PM2.5 feedback.
Most of the indoor air pollutants
fall under PM2.5 – which refers to
airborne particle pollutants smaller
than 2.5 micrometers. Common
indoor sources of fine particles are
tobacco smoke, cooking, burning
candles. Some airborne bacteria
and the smallest mold spores, pet
allergen and dust mite allergen
particles also fall under PM2.5.
