A home or place of business can collect numerous contaminants from various sources such as smoke, pollen, and pet dander in its air supply which makes it less healthy for those breathing it in. People with allergies are particularly susceptible to the effects of inhaling these substances. Fortunately there are air filtration products on the market that help make one's home or work environment a cleaner one.
Different types of purification systems are available which effectively remove contaminants from a building's air circulation. Many homes have one such system built into their furnaces or central AC, in the form of an air cleaner. This unit requires a removable filter made of fiberglass or another material that requires changing occasionally. It stops certain particles from entering the airflow throughout the building.
A HEPA filter is one which has been manufactured to meet a specific standard set out by the Department of Energy. HEPA stands for "High Efficiency Particulate Air", and it implies at less than 0.03 penetration or particles which have a size of at least 0.3 micrometers. The amount of airflow permitted by the filter depends on its size. They are very effective for removing dust and allergens.
Another design is the ionizing purifier. This system generates charged ions through an electrical field known as "corona discharge". The largely neutral particles in the air which are drawn into the filter's positively and negatively charged metal plates will either gain or lose electrons, thus creatin polarity in them which causes them to bind together and and fall out of circulation, effectively removing them from the atmosphere of a room.
Ozone generators work similarly to the ionizing system, but the main difference is that the oxygen molecules are the one affected by the corona discharge, which sits them up into individual atoms, some of which will form ozone. When ozone is released into the atmosphere of a building, it is believed to purify the air and also produce other benefits to health.
Some other filter designs work by adsorption, to eliminate unpleasant odors and airborne substances. Most contain activated charcoal or another porous material which serves the purpose of trapping various particles and filtering them out of the environment. UV filters operate by circulating air through a powerful UV beam which rids it of many infectious viruses and bacteria.
Industrial strength purifiers are generally much larger with a considerably higher filtration capacity than those used in residential homes. Sometimes the very nature of the industry calls for removal of contaminants from the air either before or after the manufacturing process. They may use mist collectors, extraction units, scrubbers, and high-density filters to achieve these results.
In order for air filtration products to operate most efficiently, there are other measures one can take to help accomplish this. Keeping the home or workplace clean in general, not smoking inside, and correcting any existing mold problem are all helpful, as well as regularly ventilating the building with fresh outdoor air. The packaging a filter comes in will usually indicate its capacity and which purpose it is most effective for, some are particularly good at removing tobacco, pollen, or other specific particles.
