Follow these simple practices to protect your self and others from active virus particles when changing air filters.

It matters where you place your portable air cleaner and where you place people when trying to reduce exposures to COVID-19.

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.

Filters come in different sizes. Some can only capture large particles, and others can catch very small particles, including respiratory particles containing coronavirus.
