How does an AHU filter indoor air?

Points on how AHU filter indoor air:

• An AHU or Air Handling Unit filters incoming and recirculated air to remove dust, pollen, and airborne contaminants.
• Air passes through multiple stages of filtration, starting with coarse pre-filters and moving to fine particulate or HEPA filters for deeper cleaning.
• This layered filtration system significantly improves indoor air quality and reduces the spread of allergens and respiratory irritants.
