Many factors can play a role in good health, and environment is one of the most important. While controlling external aspects such as temperature and humidity levels are not possible outside, they are inside with an air conditioning system. For many groups of people, having air conditioning can make a life saving difference.
The purpose of an air conditioner is to remove humidity from the air and lower the temperature. By passing the outside air through a filter before bringing it into the house, air conditioners also help to protect from outdoor allergens. Those who are plagued by seasonal allergies are encouraged to remain indoors with the windows shut and the air conditioner running. Doing this can allow those with allergies to breath cleaner air and keep their symptoms at bay.
