AIR PURIFYING APPARATUS, ROAD TUNNEL COMPRISING SAID AIR PURIFYING APPARATUS AND METHOD FOR PURIFYING AIR
Passive air purifying apparatus for along the roadside, comprising at least one inlet, and at least one outlet and an air duct connecting the at least one inlet with the at least one outlet, wherein the at least one inlet is positioned along the roadside, wherein the at least one outlet is positioned remote from the roadside, wherein the inlet is provided with a one-way valve that is biased towards a closed position, wherein the bias is such that the one-way valve opens when a valve pressure difference between a side of the one-way valve that faces away from the air duct and a side of the one¬ way valve that faces towards the air duct exceeds a threshold value, wherein the threshold value is chosen such that an over-pressure generated by a passing vehicle leads to a valve pressure difference that is greater than the threshold value.
