Air filters are essential components in keeping the air that enters the engine and cabin clean and free from debris. They are designed to trap contaminants such as airborne particles, dirt, dust, and even harmful fumes. Filtering air purifiers pass air through a filter, where polluting particles or gases are trapped, and return clean air to the room. There is some popular controversy surrounding the extent to which air filters can reduce the presence of larger particles (such as pollen, household dust allergens, mold spores, and animal dander), but most of these large particles settle on home or office surfaces and an air filter cannot remove them unless they are altered and re-suspended in the air.
Therefore, the best way to eliminate larger allergens is to clean them regularly. In a commercial environment, air filters are crucial, especially if you handle food and other living products. Electrostatic air filters are superior to more common filters, and their MERV rating depends on the manufacturer and the quality of the air filter. Electrostatic air filters perform the same filtering functions as other types of filters, but they do not clog. Air filters have three main responsibilities: trapping dust, pollen, pet dander, and other small particles and pollutants found in the air; reducing the spread of viruses and bacteria in a normal office; and removing gaseous VOCs from the air. In most homes, electrostatic air filters are superior to more common filters due to their higher MERV rating.
This rating indicates the filter's ability to capture larger particles between 0.3 and 10 microns. Particles also become a health hazard as they accumulate, as they can enter along with the air and produce bad odors. The Home Appliance Manufacturers Association (AHAM) recommends that the CADR of your air filter be equal to at least two-thirds of the room area. This fact sheet provides information on air purifiers, including the different technologies used, the selection and use. When the heating and cooling system draws air and expels it, these particles are trapped in the filter to prevent them from being recirculated throughout the house. With proper care and maintenance, the portable air filter will continue to function properly and filter the air.
The higher the CADR number for each pollutant, the faster the unit will filter the air for contaminants in a given size range. In conclusion, an air filter is responsible for filtering dust, pollen, pet dander, other small particles and pollutants found in the air; reducing the spread of viruses and bacteria in a normal office; and removing gaseous VOCs from the air. Electrostatic air filters are superior to more common filters due to their higher MERV rating which indicates their ability to capture larger particles between 0.3 and 10 microns.
