Particles as small 0.3 microns, including respiratory droplets, are collected with 99.99% efficiency.

HEPA filters are 99.999% effective at removing particulate 0.3 micron and larger.

When it comes to emerging IAQ technologies, exercise caution and do your homework.

Air filters are very capable of removing airborne viruses contained within small droplets (along with other particulate of concern) when applied properly in conjunction with an HVAC system design that balances airflow, air exchange, ventilation rates, ventilation effectiveness, and air-distribution along with other important dynamics that comprise a truly functional filtration system.
