What are VOCs?
Volatile Organic Compounds or VOCs are released into the air through gases and vapors from paints, perfumes, air fresheners, cleaning products, furniture, or activities such as smoking, cooking, or burning wood.
The most common VOCs are formaldehyde, toluene, benzene, and ethylene glycol. Long-term exposure to VOCs raises many health issues, including the risk of growing cancer.
You can learn more about VOCs and their sources in your house.
VOCs Filtering Technologies:
The technologies for controlling VOCs, odors, and gases from the air are:
- Chemical Adsorption (commonly use activated carbon as adsorption material),
- Photocatalytic Oxidation (PCO),
- Plasma, and
- Ozone generator.
Chemical adsorption is the standard method used in portable air purifiers. You can learn more about the eight types of air cleaning technologies used in consumer air purifiers.
VOC Air Purifiers Checklist:
Here is a checklist you can follow:
✓ A thick layer of activated carbon or adsorbent media
The amount of adsorbent material in the gas and odor filter is directly proportional to VOC control effectiveness. Select only those which have more activated carbon or other adsorbent material. Common adsorbing materials are:
- Activated carbon
- Activated alumina
- Zeolite
- Potassium iodide
- Earth minerals
Only select the pelletized or granular adsorbent media filter. Avoid the impregnated-type thin activated carbon sheet filters, which are less effective.
✓ Avoid Ozone Generators
Ozone generators are very effective at neutralizing VOCs and chemicals in the air. But these are not suitable for residential spaces.
Also, avoid other electronic VOC filtrations such as PCO or Plasma. These work slower and produce ozone, which is unsuitable if you have asthma or respiratory issues.
If the purifier has some electronic add-ons, make sure the device is CARB-approved.
✓ Built-in VOC Sensor
You can select an air purifier with a built-in VOC sensor for your convenience. It will automatically adjust the fan speed based on the indoor VOCs level. However, the feature is rare in consumer air purifiers. You can always get a TVOC & Formaldehyde sensor to monitor the real-time VOC concentration in your house.

Final Thoughts
The best way to remove VOCs, odors, and gases from the air is by opening windows where HVAC is unavailable. The fresh air from the outside effectively lowers the VOC concentration from the indoor air. However, when ventilation is impossible due to poor outdoor air, a portable air purifier with effective chemical filters will freshen the air.
