Do your homework when picking a portable air cleaner: it should be safe for people, big enough for your space, and have the correct filter rating.
Size Matters
Filters come in different sizes. Some can only capture large particles, and others can catch very small particles, including respiratory particles containing coronavirus.
How Filtration Reduces Exposure to COVID-19
Filtration is the process of capturing particles (including virus) on a filter surface, where they cannot be inhaled by people…
Give Your Space a Break
Balance times of occupancy with periodic intervals to give ventilation and filtration systems a chance to clear out pollutants, including virus particles.
Measuring Ventilation
Ventilation can reduce the number of airborne virus particles by exhausting them out of an indoor space. You can’t see ventilation, but you can measure it!
Use Mechanical Ventilation
Ventilation can reduce the number of virus particles by exhausting out of an indoor space. Using mechanical fans to ventilate ensures that fresh outdoor air is brought in and that stale air and pollutants, including virus particles, are exhausted out.
How Ventilation Reduces Exposure to COVID-19
Ventilation can reduce the number of airborne virus particles by exhausting them outdoors, thus reducing exposure to people indoors.
Why Handwashing Works to Prevent COVID-19
When you have direct personal contact with an infected person or touch a surface that has virus on it, the virus particles will “stick” to the oil on your skin and remain there until washed off. Soap has physical properties that loosen the particles from your skin. When you rinse your soapy hands, you wash the soap and virus particles away.
