JustAir’s Advanced Face Mask System features wearable air purifier to protect users and those around them

Technology applies “clean room” principles to create a safe, breathable environment for the nose and mouth while filtering exhaled breath.

JustAir, Inc. has launched its patented JustAir Advanced Face Mask System, the only powered air purifying respirator (PAPR) that filters inhaled air as well as exhaled air, protecting users and those around them.

The system uses positive pressure airflow principles to create a “clean room” type of environment around the user’s nose and mouth, providing fresh, filtered air while pushing away the contaminated air. Inhaled air is filtered by medical-grade HEPA filters designed to trap 99.97% of viruses, bacteria, dust, smoke, and allergens as small as 0.3 microns–a higher filtration level than N95 material, which blocks 95% of particulate matter. A carbon pre-filter reduces odors, another common complaint of mask-wearing. Finally, the mask’s electrostatic filter and multiple cloth layers filter exhaled air with a 99.9% viral efficiency, ensuring those around the user are also protected.

“N95s protect users, but they’re so uncomfortable that manufacturers will often add exhalation valves,” says Dan Burnett, Theranova’s CEO. “The JustAir mask provides two-way protection for users and those around them, and the fresh, filtered air being pumped into the mask makes it very comfortable.”


12-Hour Protection & Comfort

Originally developed to provide portable protection to people who are exposed to airborne substances–viral or otherwise–the JustAir powered system provides continuous COVID-19 protection for up to 12 hours on a single charge. With the filtered air that’s pushed into the mask, users no longer have to deal with fogged up goggles or glasses.

The company expects that dentists and other health care professionals in private practice will be among the product’s earliest adopters, as well as those who travel by air and other public transportation.

JustAir is the 14th company to be spun out of Theranova, LLC, which holds 57 patents worldwide, with an additional 180 pending. Additional information is available at
