How Do Air Purifiers Work?
Although it may seem like a new innovation, air purifiers have been around for over 200 years. At first, such as protective masks for firefighters, air purifiers have developed the ability to protect yourself and your family against pollutants in the air. Allergies and asthma affect more than 50 million Americans, concern about indoor air quality and safe has increased rapidly. Now more than ever, Americans are looking for ways to improve indoor air quality. Air purifiers the ongoing initiative to improve air quality. Allergens such as smoke, mold spores, pollen, bacteria, viruses, animal dander and other pollutants harmful to the lungs and immune system. Unfortunately, most of these irritants can not be seen with the naked eye. Air purifier filter allergens and pollutants seen or unseen by human eye. To remove these objects, air purifiers typically use filters, electrical attraction, or ozone. Air filters using fine sieves that filter particles. As the air circulates through the air purifier, plus the sieve used, the more traps the particles. The benchmark for air filters has been fixed by air high-efficiency particulate air (HEPA), which are guaranteed to trap 99. 97% of particles suspended in air above the 0. 3 microns. Micron is the standard unit used to measure the particles of air. Each micron is equal to 1 / 25, 400 cm. The naked eye can not see anything so small, so that pollutants such as bacteria and viruses to escape detection. Air conditioners filters only capture particles 10 microns or more. HEPA filters remove smaller allergens like dust, smoke, chemicals, asbestos, pollen, pet hair, pet. Many times the air passes through the HEPA filter, the cleaner the air becomes. The capacity of the room of a HEPA air purifier will determine whether the air filter that can handle your needs in filtered air. Top-of-the-line brands like Austin Air purifiers will provide approximately 15 air changes per hour in an average room and contain an average of 15 pounds of activated carbon / zeolite mixture which chemicals and absorb odors. In addition to the HEPA filter, and Alleri brands like IQAir offer an optional medical grade ultra-violet (UV) light system, used to quickly kill viruses, bacteria and fungi to enter the air cleaner. UV protects the HEPA filter to a biological contamination and viral infections. Electrical attraction is another technology used by air purifiers to trap particles. Three types of air cleaners work using electrical attraction: electrostatic precipitating cleaners, electret filters and negative ion generators. Cleaners or electrostatic precipitators, air cleaners electronic draw particles by fans and a load with a series of high-voltage son. Several plates (precipitating cells) carry opposite electric charge and attract the contaminants passing through the plates. Electronic air cleaners are perfect for those who do not want to worry about expensive replacement of HEPA filters. Electrostatic Air Cleaner Friedrich remove about 95% of all particles in suspension and exhaust energy costs low for you. Electret filters in air purifiers use synthetic fibers that create static charges to attract particles. Electret filters are offered in a variety of forms, including plain, pleated, disposable or reusable. Depending on the type of filter is necessary, determines how often the filter should be replaced. Some brands like Blueair HEPA combine technology with its own technology to support an electrostatic filter, which charges particles entering the place of the filter. Combining the two purification systems whole, created a Blueair air cleaner and more efficient. Negative ion generators or ionic air purifiers use small, dependent child or needles to create gas molecules with negative charges or ions that adhere to particles in suspension and accumulate in the filter. However, many ions end up back in the air, the sign of furniture and other surfaces that can be colored by them. Ionic air purifiers only remove certain types of particles and are not always effective against gases, chemicals or odors. Some ionic air purifiers have been shown to re-circulate dirt particles that they themselves design, making them much less effective than air purifiers with HEPA filtration traditional. Instead of using filters to capture particulates, ozone generators use electric current to high voltage for converting oxygen to ozone, which acts as a powerful oxidant and breaks down the molecules in the air and microorganisms. Several tests have shown that ozone generators are not very effective in removing indoor allergens. Ozone air purifiers, in fact, may be hazardous to health, and two ozone generators and ionic emit ozone. In nature, lightning creates ozone when it crosses the molecules of oxygen in the air. The atmosphere, ozone helps to protect against harmful UV rays, but at ground level, ozone is a strong lung irritant. When created artificially, ozone can aggravate asthma and allergies, damage to the lining of the nasal cavity and lungs, causing coughing, throat irritation, chest pains and shortness of breath. The Environmental Protection Agency and American Lung Association advises against using ozone generators. Asbestos and radon are growing problems in homes today. Heaters produce carbon monoxide and other dangerous gases and chemicals such as formaldehyde and ammonia are increasing in the home. Like most Americans remain within an average of 90% of the time, providing fresh air has never been more important. Finding a solution that respects the environment has become much easier.

The air purifier will provide asthma and allergy sufferers, with air pollutants and free to determine the quality of indoor air healthier for you and your family.
