Traditional purifiers are not enough to protect baby's healthy breathing. The purifier needs to be used in a confined space. The continuous sleep time at night is as long as 10 hours. 2-3 people are in a confined space of 10 square meters. Long-term hypoxia affects the baby's brain development. When doors and windows are closed in autumn and winter, formaldehyde has nowhere to be released. And the noise is loud, affecting children's sleep. However, this wall-mounted new fan filters the fresh outdoor air and releases it into the room to form a fresh and clean "micro positive pressure shield", which pushes dirty air out of the cracks in the building and at the same time resists external dirty air. Fresh and clean green with gray, more fresh and natural feeling.

Outdoor fresh air is filtered and discharged into the room, and the air volume discharged is greater than the amount of turbid air discharged, and the indoor air pressure is greater than the outdoor air pressure, so a micro positive pressure is formed indoors to avoid backflow of unfiltered air from the door seam. The purification area is 35-40 square meters, pure physical purification, specially designed for children's room! Five-piece filter screen triple filtration, H13 grade filter material, from dust to PM2.5, all resist. Continuous ventilation, ventilation circulation, closing doors and windows can also discharge formaldehyde out of the room.
