Portable Air Purifier Equipped on a mask to provide you 24 Hour Fresh and Cool Air anywhere.
Filters PM2.5 by 99.9%. The filter should be replaced every 500 hours (about 2 months of a M-F 8 hour shift).
An axial flow fan runs at 1650 RPM, and clean air volume passing through the filter can be adjusted. Innovative honeycomb air intake cover, three-dimensional strengthened air intake, and spiral widening air duct design make airflow more smooth.
High-level 2.35 CFM for physical labor and sports, mid-level 1.77 CFM, and low-level 1.18 CFM for daily use. A continuous stream of fresh air is sent to the mask, alleviating the stuffiness in typical masks.
Comfortable three-dimensional non-woven mask, the outer contour fits tightly to the face, preventing outside air from entering, and makes each breath clean and fresh. Adjustable nose clips.
The air pump is rechargeable and can be worn around the neck with a lanyard, or it can be attached to the helmet using Velcro.
