Air Purification to WHO IAQ Standards

The World Health Organisation has designed official air quality guidelines (IAQ – Indoor Air Quality) to offer a common standard for reducing the health impacts of air pollution worldwide. Air purification to WHO IAQ standards means a significant reduction in the levels of pathogens and toxic substances generated indoors (everything from building material fumes to cooking stove gases) as well as air from outdoors.

Air quality standards are set by each country to protect the public health of their citizens and are an important component of national risk management and environmental policies. National standards will vary according to the approach adopted for balancing health risks, technological feasibility, economic considerations and other political and social factors, which in turn will depend on the level of development and national capability in air quality management. Air purification to WHO IAQ standards varies in relation to each individual region in which the Organisation operates. For example, the guide published by the WHO’s Regional Office for Europe has extensive separate guidelines for biological pollutants, chemical pollutants, tobacco smoke and more.

Based on regular reviews of international medical and scientific evidence, a range of the most common indoor air pollutants has been identified. These include suspended particulates, toxic gases but also viruses, bacteria and mould. The guidelines stipulate the safe levels for these pollutants and Health and Environmental Ministries adopt these standards around the world.

At present and according to our knowledge, Oxyvital air quality systems are the only air purification technology in the market tested and proven to provide air purification to WHO IAQ standards.
