How Do Air Purifiers Work?
Whole-home air purifiers are integrated into your HVAC system. Before heated or cooled air is dispersed through your ductwork, it passes through a pre-filter, which captures larger particulates. From there, it depends on the type of air purifier you have. The air may pass through an activated carbon filter, HEPA filter, and/or UV light.
High-efficiency particulate air (HEPA) filters are designed to remove over 99.97% of airborne particulates. This can significantly reduce indoor air pollution and improve your home’s indoor air quality.
HEPA filters are pleated and considerably thicker than standard air filters. The dense fibers in the filter allow it to capture particles as small as 0.3 microns, including:
- Mold spores
- Aerosols
- Dust mites
- Pet dander

Portable vs. Whole-Home Air Purifiers
Portable air purifiers work well in small spaces and are easily moved between rooms. However, their coverage area is limited, and you’ll need to maintain them frequently to improve indoor air quality within a certain space, like your bedroom.
Conversely, whole-home air purifiers are installed in your ductwork. They can provide more comprehensive coverage because they work alongside your heating and cooling systems. Whole-home air purifiers provide more reliable results, especially for families where allergies, asthma, or other breathing conditions are a concern.
