WHY NOT MAKE AIR PURIFIER COMPULSORY FOR ALL MEDIUM AND BIGGER VEHICLES SAY WITH CAPACITY HIGHER THAN 2000CC
Simple solution: modify the air-conditioning system to emit some part of purified air outside the vehicle for smaller vehicles
One more solution: modify the air path entering through filter to the engine and let some part of it be emitted outside without using for the engine. This can be done for all bigger capacity vehicles like trucks and buses as well as for other vehicles also where ac is not installed.
All vehicles should act as air purifiers by installing a device in the front of the vehicles.
When the speed is more, the polluted air hits the filtering devices installed in the front and keep accumulating dust particles like the filter of air conditioners.
These dust particles are then emptied by adding some water and converted to solid bricks.
These devices will keep cleaning the polluted air on the roads which are biggest sources of pollution.
This device can be integrated with each vehicle’s radiator system and should be made compulsory for all vehicles operating in the cities.
