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 between humans and plants to ensure the healthy survival of the human species. Plants and trees, nature's natural mechanism to purify the air that we breathe, have been successfully doing the job of air-purification 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.
However, mankind's progress in the last hundred years has hindered this long standing arrangement with our natural environment. Mankind's progress towards 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 are trying to control the air pollution by introducing regulations on permissible emission levels of industries.
Today we've 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 are commonly known as are air-purifiers.
Development of home air-purifiers
You will be surprised to learn that there are many sources of indoor air pollution. These include combustive sources such as oil, gas, kerosene, coal, wood; cigarettes 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 care and cosmetic products; central heating and cooling systems such as air conditioners; outdoor sources such as pesticides all contribute to air-pollution. Some release pollutants in the air continuously while others like cleaning solvents and paint strippers do so intermittently.
Many homes are designed to let in and out as little outside air as possible. Unless they are 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 air-purifiers have today become essential to enhancing indoor air quality.
