IN 4 STEPS TO OPTIMAL AIRING
AVOID INDOOR AIR CONDITIONS THAT ARE HAZARDOUS TO HEALTH!
Occupational accidents are often caused by fatigue and lack of concentration. Here, fresh indoor air plays an often unrecognized, important role.
Irregular or permanent ventilation has been shown to be significantly more ineffective and can result in energy waste of up to 20 percent.
Poor indoor climate and lack of ventilation lead to high CO2 and aerosol concentrations in the indoor air and thus contribute to more severe infections, including respiratory diseases.
Meetings, conferences and training sessions are often less efficient and productive when participants’ ability to concentrate is limited by poor indoor air.
