HVAC (Heating, Ventilation, and Air Conditioning) air filters are designed to capture and filter out various airborne particles, including dust, pollen, pet dander, and some pollutants. The primary purpose of these filters is to improve indoor air quality by trapping and removing these particles from the air circulating through the HVAC system.
However, typical HVAC filters are not specifically designed to absorb candle output or the byproducts of burning candles. The emissions from burning candles are mainly in the form of particulate matter (soot) and volatile organic compounds (VOCs). While some of the larger particles may be captured by the filter, most HVAC filters are not efficient at removing VOCs.
To address specific concerns related to indoor air pollution from burning candles, it's better to consider alternative solutions such as using candles made from natural, non-toxic materials, limiting their use, and ensuring proper ventilation in the area where candles are burned.
For more efficient removal of VOCs and other indoor air pollutants, some advanced HVAC systems may have specialized filters or air purifiers with activated carbon or other technologies designed to target volatile organic compounds. These filters can be more effective at absorbing certain gases and odors, but they still may not be able to completely eliminate all emissions from burning candles.
