This device is used to purify air and improve air quality. It effectively removes a variety of harmful particulates, effectively isolates allergens, and protects the user's respiratory health. While competing products only remove dust, hair, PM2.5 particles, etc., this air purifier also removes formaldehyde, VOCs, and TVOC. It has a compact body, occupying only the area of an A4-sized sheet of paper, and the particle purification level reaches 350m3/h. The "Eagle Wing" bionic technology air duct design reduces the resistance of the airflow.
