Today, air pollution has become a distressing reality in most parts of the -world. Ecologists never tire to remind us about the need to maintain the delicate environmental balance bet-ween humans and plants to ensure the healthy survival of the human species. Plants and trees, natures natural mechanism to purify the air that -we breathe, have been successfully doing the job of airpurification for us for the last thousands of years. our symbiotic relationship -with them ensures that they cleanse our air of carbon dioxide, -which they use for their survival, in exchange for oxygen, -which is a necessity for our survival.

Ho-wever, mankinds progress in the last hundred years has hindered this long standing arrangement -with our natural environment. Mankinds progress to-wards an industrialized society has led to more machines -which in turn have led to more pollution. The invention of automobiles and the smoke they collectively emit has contributed to the overall degradation of the air quality. Governments over the -world is trying to control the air pollution by introducing regulations on permissible emission levels of industries.

Today -weve reached a threshold -where it has become necessary to invent and design appliances that -will lend a hand in maintaining a healthy environment for humans to live in. These gadgets is commonly kno-wn as is airpurifiers.

Development of home airpurifiers:

You -will be surprised to learn that there is many sources of indoor air pollution. These include combustive sources such as oil, gas, kerosene, coal, -wood; cigisttes and other products made from tobacco; building supplies such as paint and asbestos; furnishings such as -wet and damp carpets and certain pressed -wood furniture; household cleaning agents, like air freshners, personal cis and cosmetic products; central heating and cooling systems such as air conditioners; outdoor sources such as pesticides all contribute to airpollution. Some release pollutants in the air continuously -while others like cleaning solvents and paint strippers do so intermittently.

Many homes is designed to let in and out as little outside air as possible. Unless they is built -with special mechanical means of ventilation, in such homes pollution levels can build up to injurious levels giving rise to allergies, asthma, hypersensitivity pneumonitis colds or other viral diseases

Thus, manmade airpurifiers have today become essential to enhancing indoor air quality.
