THE SCIENCE OF CLEAN AIR

RUTGERS STUDY DEMONSTRATED PROVEN EFFICIENCY OF AIRPURA AIR PURIFIERS AGAINST SARS-COV-2

The SARS-CoV-2 virus that causes COVID-19 is transmitted by both small and large particles. Larger particles can also be expelled from infected individuals when they cough or sneeze, however these heavier particles fall to the ground, so an air purifier would have limited usefulness in this case. Your primary line of defense against getting infected with SARS-CoV-2 is to maintain social distancing whenever possible, washing your hands regularly and wearing a mask.

HEPA FILTERS IN THE FIGHT AGAINST COVID-19

The HEPA filter can trap the virus on the surface of the filter and prevent it from escaping back into the airstream.

Air filtration using high efficiency particle arrestance (HEPA) filters has become a critical weapon in the fight against the spread of COVID-19.

THE ADVANTAGE OF CIRCUMFERENTIAL OUTFLOW DIFFUSERS

A recent study concluded that the circumferential air outflow design of the Airpura air purifiers makes them less likely than air purifiers with vertical directional outflow to disperse droplets from coughing or sneezing throughout the air. This unique air outflow process of our air purifiers reduces the potential of one infected person causing an infection cluster.

AIRBORNE & AEROSOLIZED VIRUSES

Airborne transmission occurs with other viral respiratory diseases. Emission of infectious particles is common during aerosol-generating procedures such as tracheal intubation, bronchoscopy and dental procedures. The World Health Organization (WHO) recommends airborne precautions for medical workers during these procedures. Over the recent years, SARS-CoV-2 represents the 5th pathogen where hospitals have employed the same air safety protocol as they have used previously in the treatment of SARS.

  • CORONAVIRUS COULD TRAVEL 27 FEET, STAY IN AIR FOR HOURS: MIT RESEARCHER

    Pathogen-bearing droplets of all sizes can travel 23 to 27 feet. Droplets that settle along the trajectory can contaminate surfaces. Residues or droplet nuclei may stay suspended in the air for hours.

  • AEROSOLIZED VIRUS

    “SARS‐CoV‐2 remained viable in aerosols throughout the duration of our experiment (3 hours), with a reduction in infectious titer from 103.5 to 102.7 TCID50 per liter of air.”

NOT ALL HEPA FILTERS ARE CREATED EQUAL

A HEPA FILTER THAT REMOVES NEARLY 100% OF AEROSOL PARTICLES AS SMALL AS 0.01 MICRON

In studies conducted by McGill University, it was confirmed that the material used in Airpura's HEPA filters showed close to 100 % aerosol particle removal efficiency for nanoparticles. These particles are as small as 0.01 micron (10 nm).
