We offer pollution face masks and filters (PM2.5 and KN95) in small and bulk volume. Our PM2.5. and KN95 filters help to improve breathing quality in environments challenged with smog, wildfires, viruses, and air pollution of various sorts.
We all know we need to wear a face mask in Coronatimes, but most cotton or surgical masks are just not for people who have to keep moving and running around all the time. Those masks get quickly sweaty and itchy and are just very uncomfortable to wear. Try our reusable KN95 Face Masks with a PM2.5 filter: they are sweat-resistant and will not cause you chafing. Just perfect for i.e. fire-fighting- and police-force teams, for everybody running around all day long and for all types of gatherings.
Did you know that more than 50 percent of medium particles can still be found in the air after 20 minutes? According to the latest study from the TU Berlin particles from 0.01 microns to 1500 microns occur when speaking, coughing, or sneezing. After the 'beam of sneezing', for example, has been completely mixed with the room air, the distribution takes place. The smaller particles largely follow the airflow of the room, while larger particles gradually fall to the ground. The fact that humans emit very large particles only when spelled is often ignored. Normal speech and coughing generate almost exclusively small aerosols. In connection with the resumption of day-to-day work in an office occupied by several people, the scientists also simulated the particle propagation in an office occupied by four people with and without mechanical ventilation. It showed that smaller particles under 50 microns, in particular, spread far in the room without mechanical ventilation and linger for a long time. Under those circumstances, any increase in outdoor air supply makes perfect sense.
