Poor quality of indoor air is one of the biggest reasons of health problems caused by our living environment. Houses and other buildings often show excess moisture, high CO2 readings, radon etc.

Additionally, workshops, warehouses, attics, caravans and boats are examples of spaces where we spend long periods of time and indoor air quality is often poor.

Indoor air quality deteriorates if the air is not exchanged sufficiently. Indoor air should change completely about once in every two hours. In most cases this is not possible unless air conditioning and ventilation are designed according to this requirement.

Specially spaces relying only to natural change of air with no assisted ventilation system are the ones with poor indoor air quality. These spaces often have signs of mold, excess moisture, radon etc
