If not cleaned properly, an air conditioner could become a source of air pollution and the people inside that room could be affected by respiratory disorders or infections over a period of time. This is because of the dirt in the air conditioner, which carries bacteria and other harmful viruses. One can be infected if one breathes in such polluted air.

Research has proved that the indoor pollution is as dangerous as outdoor and can cause more infection as compared to the latter. For avoiding ill-effects, all one needs to do is regularly clean the air conditioner. Ideally, one should call a professional technician to do the cleaning and maintenance of an air conditioner.

It is important to examine the air filter at least once a month, or it could become a hideout for all the bacteria and fungus. These are the micro-organisms which, if allowed to remain in the air conditioner’s filter, will ultimately enter the evaporator coil and thus enter the room spreading various diseases.
