How Do Air Filters Work To Reduce Allergies?

Air filters are a product designed to filter the air in a room or office. Air filters capture air particles on a molecular basis and trap them in a filter material that pulls them out of the air flow. A variety of air filters are available from a number of manufacturers. Most air filters will remove most of the air borne germs and viruses, but some are specially designed to remove dust and particles from the air as well as chemicals and volatile organic contaminants (VOCs). An air purifier will remove particles from the air that the filter cannot trap. There are several different types of air filters available based on their design and use.

Particle traps come in two forms: physical and chemical. A physical filter is simply a material consisting of small pores or struts that catches airborne particles on a molecular level and holds them until they are removed by the air filter. Physical filters can be used to clean the inside of a furnace or other mechanical parts of a space that are continually being used by employees. Chemical filters are generally used in offices where physical filters would be impractical or undesirable because many employees would be unable to clean or maintain their furnaces without assistance.

Air filters can be installed in any home, work, school, or other building to reduce or eliminate allergic reactions, increase air quality, and improve respiratory health. Air filters should be considered a long-term investment in preventing illness and disease. Asthma and other respiratory illnesses are a leading cause of missed days at work. According to the American Lung Association, air filters can prevent as many as 90% of all asthma-related admissions to the emergency room.
These air filters have the potential to reduce or eliminate asthma attacks in children and decrease the number of allergy-related contact dermatitis cases in adults. Studies show that air pollutants, particularly fine dust and pollen, contain at least one protein that has been linked to causing allergic reactions. Asthma and other respiratory illnesses can also aggravate existing allergies and produce symptoms similar to those of eczema or hay fever. Pollen is even more irritating to allergy sufferers because it is easily inhaled. Dust and pollen can contain more than two thousand different allergenic proteins that may trigger an asthma attack.

The question of how do air filters work to reduce or eliminate allergies has been addressed countless times in popular media. Often this leads consumers to purchasing the first air purifier they run across, assuming that all allergy symptoms will be eliminated if they purchase the right purifier. However, the air that passes through an individual's nasal passages is not completely pure. Even though an allergy sufferer may have perfectly fine skin, there is always some amount of dust or pollen in the air that needs to be breathed in. Air filtration removes at least 90% of these microscopic particles before they are able to enter the respiratory system.

There are a number of different types of air filters, but the most common are ionic, wet cell, charcoal, protein, fume and fine particles. Each type works best on a particular particle of pollutants. Ionic filters use positively charged ions to attract dust and pollen particles. This air filters from the best Discount Filters company, work well in most environments and offer good results. Cell filters use negatively charged ions to draw in polluted particles such as lead and other metallic pollutants. Wet cell filters use a wetting process to attract dust and may need to be replaced every so often. Check out this post that has expounded on the topic:
