There’s an Advanced Method to Protect Against COVID-19, Without Masks

N95 masks depend on making a perfect seal with your face. If there are any imperfections, a poor fit, or a leak, the effectiveness drops to almost zero. Masks are also notoriously uncomfortable, aren’t sized to fit children, and people often take them off in public to eat, drink, or adjust the fitting.

HEPA filters have similar problems: their effectiveness varies with particle size and is susceptible to imperfections in sealing. And most filters don’t actually inactivate viruses or bacteria.

Other approaches, such as UV light and ozone fumigation, have their own set of drawbacks. They require more time to treat the air, and UV effectiveness varies as bulbs age and as standoff distance from the bulbs increases.

Taza Aya’s Direct Air Treatment Module Is the Next Level of Pathogen Protection

Our Direct Air Treatment Module (DATM) removes pathogens and inactivates them more reliably and effectively — and economically — than other air treatment solutions. The DATM can be used in a large-scale HVAC format or as a wearable device, with far less intrusion and discomfort than N95 masks.

By directly exposing contaminated air to a non-thermal plasma (NTP), the DATM both removes airborne particles and inactivates them instantly. 

Non-thermal plasmas have been used for years to generate ozone as an indirect form of contaminant treatment for drinking water or to sterilize surfaces — similar to disinfecting with chlorinated water. Ozonation, like UV treatment, requires seconds to minutes of treatment time to be effective. Such treatment times translate into meters-long treatment chambers when dealing with air flows of 3-10 meters per second.

Taza Aya’s DATM uses a non-thermal plasma for direct treatment by exposure to the NTP itself,  instead of indirect treatment by exposure to ozone as an NTP byproduct. The DATM operates at lower power levels and yet generates powerful radicals and excited molecules that inactivate airborne viruses rapidly. The result is greater sterilization in an instant.

not a particle filter

Particle filter performance, including HEPA filters, depends on particle size.  Most viruses are exceptionally small. NTPs inactivate viruses of any size. 

works in an instant

DATM inactivates viruses in an air stream on the fly. There’s no need for extended treatment times using UV or other inactivating agents.

low power & compact

10X to 1000X lower energy means lower power consumption and lower ozone concentrations.

National Academies report calls for rethinking who has a right to respiratory protection - and how

June 24, 2022

Important report from a National Academies of Science, Engineering, and Medicine (NASEM) committee recommending future frameworks for expanding the availability of respiratory protection (historically, N95 masks but potentially newer approaches such as Taza Aya’s in the future) that go beyond the current limited list of professions to all workers potentially exposed to respiratory hazards (including airborne pathogens) and the public at large, including children.

A mandate for rethinking how we view - and what we demand of - personal respiratory protection!

Covid loses 90% of ability to infect within 20 minutes in air – study

Herek Clack / January 20, 2022

Coronavirus loses 90% of its ability to infect us within 20 minutes of becoming airborne – with most of the loss occurring within the first five minutes, the world’s first simulations of how the virus survives in exhaled air suggest.

The findings re-emphasize the importance of short-range Covid transmission, with physical distancing and mask-wearing likely to be the most effective means of preventing infection. Ventilation, though still worthwhile, is likely to have a lesser impact.

“People have been focused on poorly ventilated spaces and thinking about airborne transmission over meters or across a room. I’m not saying that doesn’t happen, but I think still the greatest risk of exposure is when you’re close to someone,” said Prof

“We envisioned the need for future pathogen protection to go beyond traditional respiratory devices, and integrate seamlessly into our daily lives, becoming an ‘invisible shield’ against pathogens.

We believe Taza Aya demonstrates ingenuity and exceptional vision in their aim to deliver respiratory protection to individuals, families, and communities around the world.”
