Although natural ventilation is good for achieving a minimum degree of purification of a space, it is not the most appropriate solution. Some concentrations of pollutants, such as nitrogen dioxide (NO2), are very difficult to remove with natural ventilation. On the other hand, the air that normally enters your spaces is the same polluted air from the streets, so you would be substituting one problem for another. Thanks to the technologies in our products, an AIR8 purifier guarantees you purified and healthy air without the need to open the window. Due to its high Clean Air Delivery Rate (CADR), the air that will be breathed in your space will be of much higher quality than the air you would breathe just by opening the windows.
