Q:Can AirPro Mask HEPA filter Covid-19 virus?
A: Yes, The virus that causes COVID-19 is approximately 0.125 micron (125 nanometers) in diameter. It falls squarely within the particle-size range that HEPA filters capture with extraordinary efficiency: 0.01 micron (10 nanometers) and above. Filters meeting the HEPA standard must satisfy certain levels of efficiency. Common standards require that a HEPA air filter must remove—from the air that passes through—at least 99.95% (European Standard) or 99.97% (ASME, U.S. DOE) of particles whose diameter is equal to 0.3 μm; with the filtration efficiency increasing for particle diameters both less than and greater than 0.3 μm;
Q: What is the AirPro filter martials?
Q: What micron level does Broad airpro mask filter down to?
A: 0.01 micron (10 nanometers) and above. Broad Airpro mask air filter meet the HEPA13 standard, the filter must remove 99.97% or more of all particles which are 0.3 microns (micrometers) in diameter, with the filtration efficiency increasing for particle diameters both less than and greater than 0.3 μm;
Q: What is the Broad airpro mask air flow in cubic ft./min?
A: Three speed adjustment, low-level 1.18 CFM for 12 hours; Mid-speed 1.77 CFM for 8 hours; High-speed 2.35 CFM for 4 hours.
Q:How long does Broad airpro mask on one charge?
A: About 3~4 hour on one charge.
Q: I understand that a person has to have a fit test in order to wear a N95 mask so how can we be sure we are properly fitted?
A:Broad airpro mask is the Powered air-purifying respirator (PAPR) provide positive airflow respirator, means excess air or “positive air” being pushed into the mask and out through its vents. Because of this solution positive air pushes out exhaled air increasing the overall effectiveness of the mask by removing unwanted bacteria from the breathing zone. even face mask is not perfect fitted, not affect the protection. And With excess air being produced on-demand, always have access to fresh, filtered air.
Q: how Long first Battery charge?
A: 6 hours.
