You have truly highlight that how when will inhale unfiltered air in which there would be germs then we may feel a lot of respiratory zone and especially they would start from shortness of breath and many time we don't understand and don't think about air in which we are living and ultimately our environment in which there is dust and poisonous chemicals and gases becomes the source of our respiratory disorders that's why I am happy that you highlight the importance of clean and clear air.

Thanks for sharing...
