Air Purifiers: Combating The Surge In Asthma Cases
Asthma statistics in the United States are quite alarming. If the data is to be believed, 7.3 percent of Americans are suffering from asthma. The chief culprit behind this exponential rise in Asthma cases has been identified as pollution.
Indoor Pollution As A Causative Factor
The Environmental Protection Agency, EPA in 1990 identified indoor air pollution as the biggest cause of airborne diseases. The EPA also came up with several suggestions for dealing with the problem. Few of the suggestions laid down by the EPA are:
● Limit indoor pollution by ensuring adequate ventilation systems at home.
● Maintain control on sources of indoor pollution, such as paints, heating equipment, pets, etc.
● Use efficient indoor air purifiers.
Why Air Purifier Use?
Air purifiers come highly recommended as an ideal solution for regulating and eliminating indoor air pollutants. There are various crucial points that should be kept in mind before the installation of air purifiers can begin. Some of these points are — every nook and corner of the house should be clean and smokers should be kept out of the house.
While buying air purifiers and air filter accessories, remember that for air purifiers, there are no established standards, however, the Food and Drug Administration has ranked some air purifiers as Class — II medical devices. This means the fact that air purifiers have medical benefits is fact and not the case of medical quackery. One more point, you should keep in mind is — the rating system used by manufacturers of these devices has no relation to the performance of the devices.
Before the purchase, installation and optimum usage of air purifiers it is important to understand the varieties of available air purifiers and their specific usage. In this article, we look into different types of air filters and will also discuss about their features and use.
Types of Air Purifiers
Generally there are five types of air purifiers. These are as follows:
Mechanical Air Purifiers
Mechanical air purifiers are like the fan-driven High-Efficiency Performance Assistance, HEPA filter, which forces air through specific barriers, trapping irritant and allergen particles in the air. Good quality HEPA filters are able to trap approximately 99.7 percent of all particles.
Electronic Air Purifiers
Electronic air purifiers are ion-type purifiers and uses electronic charges to attract and trap particles. Though, these air purifier produces hazardous ozone by-products that can risk human-health at a great extent. These ozone by-products have potential to cause lung-related diseases. Therefore, before buying this air purifier, ask the manufacturer to prove that the device is in the line with the code set up by Code of Federal Regulation.
Hybrid Air Purifiers
Hybrid air purifiers are the combination of mechanical and electronic air purifiers. These air filters capture dust, allergens and microorganisms. The germicidal Ultraviolet or UV lamp used in this air purifier is lethal to hazardous microorganisms such as dust mites. Hybrid air purifiers are a perfect choice for large spaces such as office or commercial complexes.
Gas Phase Air Purifiers
Gas phase air purifiers are not good at extracting allergens or irritants from the air. This device is used to remove odors caused by non-particulate pollutants, such as perfume, paint, cooking gas, etc.
Ozone generators produce ozone as a direct product. Technically, ozone generators extract pollutants from the air — however, due to the high levels of ozone generation, this device is not recommended at all.
