The Dyson HEPA Big+Quiet Formaldehyde air purifier addresses air quality issues in shared spaces to take indoor air purification further. It features more than double the airflow of previous Dyson purifiers at up to 90 liters of airflow per second of purified air. A carbon dioxide sensor reports CO2 in real time, indicating to people in shared spaces when to ventilate.
A re-engineered motor bucket ensures quiet operation, measuring just 55.6 decibels of noise on maximum airflow speed. The three-phase filtration system captures up to 99.97% of fine particles, removing odors and gases like NO2, benzene and VOCs and permanently destroying formaldehyde.
