According to studies, indoor air is often two to five time more polluted than outdoor air. Even though we don’t notice it, the air contains countless micro particles and bodies imperceptible to the human eye. In addition to the pollutants that may come directly from the outside of an office, air conditioning ducts often play a crucial role in safeguarding and propagating germs, which in some cases can severely affect the health of occupants.
The most frequent symptoms experienced by occupants of a building with poorly maintained air ducts are
Shortness of breath
Itching
Headache
irritation of eyes, nose and throat
Hoarseness
Rashes
Increased incidence of respiratory infections and colds
Mental fatigue
Feeling dry mucous membranes and skin
Nausea, dizziness and vertigo
Cleaning your air ducts will improve the quality of the air and will reduce symptoms in your office. At your house try opening your windows as much as you can to ventilate the rooms.
