HELDA / Air pollution MASK


One of the problems while using air masks is the moisture and unpleasant odor in their inner space caused by user's exhalation. HELDA have two filters with two different functions.An air filter to clean up the inhaled air and another filter that is filled with medical and aromatic herbs like grinded leaves and sublimated tablets to refine the inhaled air.This extract is activated by the moisture of the exhaled air and reduces the humidity and refreshes the air inside of the mask and prevents unpleasant odor.Besides in common cold, one can use the mask to prevent the transmission of disease and apply Eucalyptus extract to facilitate treatment.
