A healthy indoor climate is threatened by human influence, microbiological factors, moulds, yeasts, bacteria and particles from building materials, such as asbestos (see below).

Indoor air quality has a direct influence on people's wellbeing and productivity. The health of the workplace and other premises is affected by their temperature and humidity, as well as chemical, physical, and biological conditions. In a healthy building the indoor climate is clean, providing a good environment for living and working.

Is indoor air the cause of health problems?
Poor indoor air can cause health problems. With an indoor air inspection you can ensure that the workplace is safe and locate the factors decreasing the air quality.

Chemical conditions

Indoor air may contain chemical compounds that are health hazards. These contaminants can be particles or gaseous, and either organic or inorganic. Health hazards can be caused by ammonia, asbestos, formaldehyde, carbon dioxide, carbon monoxide, styrene, volatile organic compounds, dust and cigarette smoke.

Physical conditions

The quality of indoor air decreases when the room temperature is too high or too low, as well as with humidity and aridity. Radiation and draft can also adversely affect air quality.

Microbiological conditions

Microbes in the building can also reduce indoor air quality, the most frequent of which are moulds, yeasts and bacteria.
