Ventilation is a very important factor in the comfort and hygienic in homes, meeting rooms, offices, etc.
In places that do not have sufficient air renovation, the air is quickly saturated with odors, steam, carbon dioxide, smoke, etc., causing breathing difficulty due to the air pollution.
We breath 36 pounds of air each day. We eat 3.8 pounds of food and we drink 4.3 liters of water. Pollution free air is important for our health and comfort.
