Why do we need to remove VOC (formaldehyde) after renovation?
Formaldehyde (HCHO) is dangerous to human health. Building materials, home furnishings pressed woods, wood floor finishes, paints, upholstery fabrics are often the major sources in homes because materials off-gas formaldehyde over time.
People often spend more than eight hours a day in their homes; infants, kids and the infirm sometimes even spend the entire day inside their home. WHO (2000), Guidelines for Air Quality suggests that the level should below < 100 µg/m3 to avoid acute effects in such individuals.
What is formaldehyde?
Formaldehyde is one of the Volatile Organic Compounds (VOCs). Formaldehyde is a colorless, flammable gas at room temperature, has a pungent, distinct odor, and may cause a burning sensation to the eyes, nose, and lungs at high concentrations. The U.S. Environmental Protection Agency (EPA) has classified formaldehyde as a known human carcinogen. There is some evidence of asthma or asthma-like symptoms for children exposed to formaldehyde in homes.
Why do we measure TVOC reading together with formaldehyde reading?
World Health Organization defined volatile organic compound (VOC) as any organic compound whose boiling point is in the range from 50 °C to 250 °C. VOC can be found within nature environment, furnishings, building materials, glues and carpets. Formaldehyde, acetaldehyde and benzene are examples of VOC.
HK Environmental Protection Department & Finnish Society of Indoor Air Quality and Climate set the TVOC at 200 & 600 μg/m3 or 0.087 ppm & 0.261 ppm as Excellent Class and Good Class respectively.
If we adopt formaldehyde (CH2O) as the only measuring unit, other VOC gases like acetaldehyde and benzene may still be found in homes or offices. For example, if 0 ppm is recorded for formaldehyde, it doesn’t mean there is no other toxic VOC within the space.
