Air Cleaner Filters

Air Cleaner Filters

Air cleaner filters are used to remove a range of contaminants from the air including pollens, dust, dirt particles, allergens, and undesirable odors. Filters help to improve the conditions of the air which is important in living and working spaces, as well as for machinery, engines and appliances. Air filter devices utilize screens or meshes made of various materials, including cotton, polyester, gauze, and metal mesh. Air cleaner filters such as HVAC filters or exhaust filters help to keep air clean and contaminant-free and are commonly used in conjunction with home or commercial heating and cooling systems. In public spaces, the rise of asthma and allergy sufferers has led to a rise in the implementation of filtration systems to create a cleaner air environment. By removing allergens and contaminants from the air, affected people are able to breathe more easily. Air cleaner filters are therefore commonly used in conjunction with home or commercial heating and cooling systems. Another important use of air cleaner filters is in the protection of delicate machinery and engine components as inline filters or membrane filters. In industrial settings, debris and contaminants in the air are a common occurrence. These particles can enter into the inner compartments of machines and tools and build up over time to create an obstruction, or to wear down materials and parts. Using air filters to clean the air entering the inside of these motors or engines allows for easier maintenance and a longer lifespan for components.

When determining the best type of filter for an application, there are a number of important specifications to consider. Filter fiber length and size affects the efficiency of a filter screen. The fibers in air cleaner filters can be of various sizes and densities and depending on the porosity of the filter can allow for different airflow speeds. In general, filters that are designed to capture larger particles and contaminants have large fibers, while those designed to catch the smallest of unwanted particles have small fibers. Materials which are typically used in filter construction include acrylics, carbon, wire and metal mesh, fiberglass, fabrics and polyurethane foam. Air filters can be designed to meet specific filtration needs. For example, HEPA filters (High Efficiency Particulate Air) have particular standards that are regulated by the government in order to ensure a consistent quality of filters marketed as HEPA. HEPA filters are used to catch the smallest particles of any type of air cleaner filter. Air filters designed for industrial environments are typically high capacity and constructed from relatively heavy-duty materials.
