HEPA filters are designed to capture particles like the small PM 2.5 particles. Activated carbon, though, captures odors and gases like volatile organic compounds (VOCs). VOC is a big category and includes harmful carcinogens like formaldehyde and benzene.
Does everyone need a carbon filter?
Not necessarily. Not all homes have dangerous levels of harmful gases or VOCs that would call for a carbon filter. VOCs are more common in homes:
- with recent home renovation or repainting
- with smoke or other offensive odors
- near a source of gas pollution like a factory
If you have inflammation or asthma symptoms, you may also consider using a carbon filter.
Purifier companies have a financial incentive to convince people to buy carbon filters. They make more money if they can scare people into buying carbon. We won’t do that.
