Volatile Organic Compounds (VOCs)
Understanding the impact of different sources of indoor VOC pollution is central to Dyson's research and development. Made up of carbon, hydrogen and sometimes oxygen, VOCs are potentially harmful compounds that can emit from common household items. DIY and personal care products, cleaning sprays, candles and perfumes are all common offenders.
A colourless gas that can be released from materials such as plywood and fibreboard, insulation and do-it-yourself products like paint, wallpapers, varnishes and household cleaning sprays. Formaldehyde is 500 times smaller than 0.1 microns and particularly difficult to capture. When left undetected, it can be trapped in a home for years.
A reddish-brown gas released into the home through gas appliances, open flames, wood burning stoves and cigarettes. Fossil fuel combustion is a huge source of NO2 and it can enter through windows and ventilation.
A complex mixture of extremely small solid particles and liquid droplets suspended in air. PM10 particles such as pollen and allergens, are small enough to pass through the throat and nose and enter the lungs. PM2.5 are microscopic particles from sources such as industrial emissions, bacteria and fungi. PM0.1 are inherently unstable particles that can easily grow into larger particles through coagulation and condensation. They’re mostly found in vehicle exhaust emissions and tobacco smoke.
