IETT launched a fragrance application on buses operating in the metrobus line, which exceeds the number of trips per day. Placed in the air blowing points in the Metrobus, mixed aroma flavored fragrances are distributed evenly inside the vehicle, which will not disturb the passengers.
In summer the air conditioner will be distributed with air blown through the apparatus placed in the heating unit in the winter. The smells are lavish, tangerine and sandalwood. According to the IETT statement, smells that are approved by the Ministry of Health are antibacterial and do not harm human health in any way.
