VOC sensors detect volatile organic compounds (VOCs)—gases released into the air from many everyday products and activities, including household cleaners, paints and solvents, cooking odors, fragrances, and personal care products.
VOC readings indicate the presence and concentration of gases, not whether those gases are harmful at typical household levels. A temporary rise in VOC levels during fragrance use is common and usually decreases once diffusion stops or fresh air is introduced into the room.
If you see a VOC spike after using aroma oils, it means:
The sensor is functioning as intended
Fragrance-related gases have been detected
The purifier may automatically increase fan speed to help refresh the air
VOC levels should gradually return to normal once the source is removed. To minimize spikes, avoid placing aroma diffusers directly next to air purifiers.
