Frequently Asked Questions
Cloth and surgical masks prevent the spread of COVID-19 by blocking exhaled breath, but they don't filter the air you breathe. N95 respirator masks, on the other hand, protect the user by filtering inhaled air, but they’re uncomfortable and make breathing difficult, so valves are often added that allow unfiltered exhaled breath.
The JustAir advanced face mask system features a filtering system that includes both carbon and medical-grade HEPA filters for filtering inhaled air at a higher filtration level than N95 material (99.97% instead of 95%). The battery-powered air filtering system provides clean, filtered air for up to 12 hours on a single charge, while the JustAir mask features an electrostatic filter and multiple cloth layers that filter the air you exhale with a 99.9% viral filtration efficiency.
The JustAir mask was designed for comfort. The soft, comfortable cloth mask is adjustable. When used with the air filtering system, it delivers cool air, keeping humidity from building up. Fresh, clean air for up to 12 hours and no fogged glasses.
Air flows from high pressure to low pressure areas. When an area is kept at a pressure higher than its surroundings, you have positive pressure. Cleanrooms and bio-labs use positive pressure to push contaminants out by filling them with clean, filtered air. The JustAir system uses the same positive pressure principle. Air is filtered by medical-grade HEPA filters in the blower pack and pushed into the mask to maintain positive pressure. The filters are designed to trap 99.97% of particulate matter as small as 0.3 microns.
The blower pack is able to provide up to 150 L/min of air through the tubing. For reference, the average breathing rate of someone exercising peaks at about 120 L/Min.
JustAir works best on a clean, shaven face. A beard will prevent the JustAir mask from properly fitting, which may prevent your exhaled air from being filtered, thus reducing the goal of protecting others.
