Ionic Ozone
Although they may seem like a new innovation, air purifiers have been around for over 200 years. Beginning as protective masks for firefighters, air purifiers have now developed the ability to protect yourself and your family against airborne pollutants.
As allergies and asthma affect more than 50 million Americans, concern for quality and safe indoor air has increased rapidly. Now more than ever, Americans are seeking ways to improve their quality of indoor air. Air purifiers head platoon in progress to improve air quality.
Allergens like smoke, mold spores, pollen, bacteria, viruses, dander animals and other pollutants harmful to lungs and immune system. Unfortunately, most of these irritants can not be seen by the eye nu. 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 utilize fine sieves that filter particles from the air. As air circulates through the air purifier, plus the sieve used, the more it traps the particles. The accepted benchmark for filters Air was set up by Efficiency Particulate Air (HEPA), which are guaranteed to trap 99.97% of airborne particles larger than 0.3 microns. Microns are the standard unit used to measure air particles. Each micron is 1 / 25, 400 inch. The naked eye can not see any thing so small, so the pollutants such as bacteria and viruses to escape detection. Room air conditioner filters only capture particles 10 microns or more. Filters HEPA remove smaller allergens like dust, smoke, chemicals, asbestos, pollen, pet dander.
The more times the air passes through the HEPA filter, the cleaner the air becomes. The room capacity of a HEPA air purifier will determine if the air filter can handle your needs in filtered air. Top-of-the-line brands like Austin Air purifiers will provide approximately 15 air exchanges per hour in an average room and contain an average of 15 pounds of activated carbon / zeolite blends, which adsorb chemicals and odors.
In most of the HEPA filter, brands like and AllerAir IQAir offer an optional medical grade ultra-violet (UV) light system, used to kill rapidly viruses, bacteria and fungi to enter the air purifier. UV protects the HEPA filter to a biological and viral contamination.
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 electrostatic precipitators or electronic air cleaners, the particles get a fan and charging a son series of high voltage. Several plates (precipitating cells) carry the opposite electric charge and attract the contaminants as they pass by the plates. Electronic air purifiers are perfect for people who do not want to worry about expensive replacement of HEPA filters. Electrostatic Air Cleaner Friedrich eliminate about 95% of all particles in suspension and discharge energy costs low for you.
Electret filters to air purifiers use synthetic fibers that create static charges to attract particles. Electret filters are offered in a variety forms, including plain, pleated, disposable or reusable. Depending on the type of filter you need, will determine how often the filter must be replaced.
Some brands like Blueair HEPA combine technology with their own technology of electrostatic filter media, which charges the particles volume instead of the filter. By marrying the two unique purification systems together, Blueair air created a cleaner, more efficient.
Generators negative ions or ionic air purifiers use tiny, son or needles in charge of creating gas molecules with a view negative charges or ions that adhere to suspended particles and accumulate in the filter. However, many ions end up back in the air sticking to furniture and other surfaces that may be colored by them.
Ionic air purifiers remove only certain types of particles and are not always effective against gases, chemicals or odors. Some ionic air purifiers have been shown to recirculate the same dirty particles that they draw in, making them much less effective than HEPA air purifiers using traditional filtration.
Instead of using filters to capture particulates, ozone generators use high voltage electrical currents to convert oxygen ozone, which acts as a powerful oxidant and breaks down molecules and microorganisms in the air. Several tests have shown that the generators Ozone is not very effective at removing indoor allergens.
Ozone, in fact, can be dangerous for your health, and two ozone generators and ionic air purifiers emit ozone. In nature, lightning creates ozone when it crosses oxygen molecules in the air. In the atmosphere, ozone helps protect us against harmful UV rays, but at ground, ozone is a powerful lung irritant. When created artificially, ozone can aggravate allergies and asthma, damage the nasal mucosa and lungs, causing coughing, throat irritation, chest pains and shortness of breath. The Environmental Protection Agency and the American Lung Association advise against using ozone generators.
Asbestos and radon are growing problems in homes today. Produce heating carbon monoxide and other dangerous gases and chemicals such as formaldehyde and ammonia are increase in the home environment. Like most Americans remain within an average of 90% of the time, providing more air cooler, cleaner has never been more important.
