No ... their purpose is to transfer the heat from inside to the outside. No harmful chemicals are released to the air in this process unless the A/C system has a leak, in whic…h it would no longer be cooling the interior of the space and people would notice that right away and get it fixed. Yes! they do if they are faulty or the freon gas escapes when they are scrapped or not serviced correctly. Not to mention the coal, natural gas or oil used to produce the electricity needed to operate them. (MORE)
Ash released from a volcano, carbon monoxide released from avehicle's exhaust, and sulfur dioxide released from factories allpollute the air we breathe. Nitrogen oxide is prod…uced duringthunderstorms by electric discharge. (MORE)
Anything that adds material to the air that isn't oxygen, nitrogen, water vapor or argon can be said to be polluting the air. This would include air freshener, cologne, perfum…e, the aroma of peanut butter cookies, or flowers. Generally though "pollution" is used to describe things that we don't enjoy or are bad for us - bad odours, dusts, poisonous materials, smoke, or greasy vapors. With attention to air fresheners. They work in several potential ways: .
Adsorbing the odours onto activated carbon or similar materials .
Chemically neutralizing the odour .
Destroying bacteria that cause odours .
Obscuring odours with a perfume .
Anesthetizing the sense of smell .
Many of these compounds are associated with health impacts like asthma, are toxic or are not pleasant to smell, so air fresheners could be said to pollute the air (MORE)
Air pollution has many affects. If it is in the form of gases inthe atmosphere, it can cause global warming and Ozone Layerdepletion. These gases can also condense within clou…ds and pollutethe rain that falls, subsequently polluting the water and land thatthe rain falls onto. Also, air pollution can be very harmful ifbreathed in by humans. While there are many different levels of howsevere the air pollution is and different people have varryinglevels of sensitivity, but an alright AQ I (Air Quality Index) can cause irritation in sensitive people,like those with asthma or breathing problems. A bad AQU can causelung problems in all people, and can be deadly if left for too longor if breathed in too much. Bad and polluted air can kill offanimals that depend on fresh oxygen, like fish and microorganisms,and can also harm plant life and vegetation. (MORE)
If you mean "on air" as with radio and television, mobile telephones etc., then no they do not. They are part of the electromagnetic spectrum and are transmitted through this.… I suppose you could say they pollute the electromagnetic spectrum. (MORE)
Air conditioners do not pollute the air when working but it is at the time of manufacturing when refrigerant is filled. During dis process some refrigerant escapes to atmosphe…re and thus for every day around the world ac/fridge production causes huge damage to Ozone layer. (MORE)
cent % is not possible, but certain level we can i.e. .

Clean air and polluted air... they are two very diffrent things.. The diffrence between them is clean air is good for our enviorment its fresh and clean good to breath. But po…llusted air is bad air that makes the cloud black. It then rains acidic rain which is extreamly bad for our earth...! (MORE)
Everyone pollutes the air to a certain degree. Everytime someone uses a cooking fire, electric stove, automobile, throws away trash or garbage, or even excretes bodily waste, …or passes gas they (we) are producing pollution of one or more types. It isn't that we all pollute but to the degree that we all pollute. Some pollute more than others, for various reasons. (MORE)
