Today, high quality filtration must be used to protect building users from airborne particulate and micro-organisms that can cause sickness, dizziness and allergic reactions. Air filters are the first line of defense and must perform the following functions:

Preventing micro-organisms from entering the system.

Protecting building users from re-circulated air that has been contaminated by micro-organisms that may have grown in the building or entered through unfiltered openings.

Arresting particulate from the air, thereby removing a transport mechanism for smaller micro-organisms and protecting equipment from damage.
