There are three main types of air filters:

HEPA Filters

High Efficiency Particulate Air (HEPA) filters remove 99.97% of particles that are 0.3 microns and larger from the air. This makes HEPA air purifiers ideal for removing small pet dander particles, dust mite residue, and pollen from your air.

HyperHEPA units are certified to work even more effectively than traditional HEPA air purifiers. They are ideal for the cleanest residential air possible.  

Carbon Filters

Using activated carbon, carbon filters remove odors and chemicals from your indoor air. These odors and chemicals include cigarette smoke, fireplace fumes, formaldehyde, volatile organic compounds (paint fumes, carpet glues, new building materials, etc.), pet odors, and kitchen odors. The more carbon in each filter, the more odors they will remove.

Pre-Filters

These filters are a great benefit because they help extend the time between filter cleanings or changes as well as maintain the air purifier’s functionality and efficiency. Pre-filters do this by trapping large particles before they reach the main filters of the air purifier.
