Let’s Clear the Air: Understanding HEPA Filters vs. Carbon Filters

Which Filter is Best?

When it comes to choosing an air purifier, the number of choices and variety in filters can be overwhelming. The most common types are HEPA and carbon filters, each with its own set of benefits. Let’s delve into the differences between the two to help you make an informed decision for your air purification needs.


HEPA Filters

HEPA, or High-Efficiency Particulate Air, filters are known for their ability to capture microscopic particles with efficiency. They can trap 99.97% of particles as small as 0.3 microns. This includes dust, pollen, pet dander, and mold spores, making them a valuable asset for allergy sufferers and anyone concerned about indoor air quality.


Advanced HEPA Filters

Advanced HEPA filters take filtration to the next level as they often capture even smaller particles than standard HEPA filters.  This means even tinier pollutants and allergens are effectively captured from the air. Advanced HEPA filters provide unparalleled purification and relief for allergy sufferers.


Carbon Filters

While HEPA filters excel at capturing particulate matter, they may not be as effective at eliminating gasses, odors, and volatile organic compounds (VOCs. This is where carbon filters come into play. Activated carbon filters are highly porous with a large surface area. This allows them to absorb many gasses and odorous molecules, effectively neutralizing unpleasant smells and harmful chemicals.


The AirDoctor Difference

This is where AirDoctor’s cutting-edge filtration technology comes in. AirDoctor air purifiers are equipped with a 3 stage filtration system comprised of an UltraHEPA filter, a carbon VOC filter and pre-filter. The UltraHEPA filter captures 99.99% of particles as small as 0.003 microns, ensuring the capturing of even the smallest airborne contaminants.

Additionally, AirDoctor utilizes an advanced carbon VOC filter specifically designed to target volatile organic compounds and odors. This filter is engineered to maximize adsorption capacity, effectively trapping harmful chemicals and neutralizing unpleasant odors, leaving your indoor air fresh and clean.

When compared to competitors, AirDoctor’s UltraHEPA and carbon VOC filters stand out for their superior performance and advanced filtration capabilities. While other air purifiers may offer basic carbon filters that provide limited odor control, AirDoctor goes above and beyond to ensure comprehensive purification, tackling both particulate matter and gaseous pollutants with unmatched efficiency.



In conclusion, while both advanced HEPA filters and carbon filters play vital roles in air purification, combining the two offers the best of both worlds. With exceptional particle removal and superior odor control, AirDoctor’s 3 stage filtration remains unparalleled. With AirDoctor, you can breathe easy knowing that your indoor air is free of allergens, harmful gasses and unpleasant odors.
