Basically air purifiers are appliances that aid in removing pollutants from air. They are very helpful devices for people who suffer from asthma or allergies. Air purifiers help in getting rid off second hand smoke, hence it is very useful if you have a smoker at home.
Air purifiers serve residential as well as commercial needs. Commercially air purifiers serve various industrial, medical and commercial industries.
Air purifiers have HEPA (high efficiency particulate air) filters that aid in cleaning the air around that is circulated. They help get rid off contaminants and impurities from the air. It is possible for the HEPA filter to remove about 99.9% of dust particles bigger than 0.3 microns (the standard measure for microns). HEPA filters can clear the air of dust, pollen, pet dander, smoke and almost all pollutants present in the air.
Following are the advantages of air purifiers:
Air purifiers actually clean the air around us purifying it by removing microns of 0.3 and larger size to render it 99.9 percent dust free.
Some purifiers are designed keeping in mind people suffering from asthma. Such purifiers can make the air free from all kinds of particles causing allergies and even other impurities so that the patients get to breathe pure air.
When you are about to buy an air purifier ensure that your appliance is in sync with the Room Air Cleaner Certification Program standards listed. There is a standard set for air purifier appliances. Clean air delivery rate or CADR is a measure that evaluates the percentage of dirt free air in cubic feet.
Air purifiers can suck up second hand smoke and even eliminate any smell in the air.
Iconic purifiers are of great aid to people who have health issues as they help in cleaning the tiniest particles in the air.
To ward off bad odors from the air ozone purifiers are effective as they are capable of removing medicinal odors, heavy cooking smell and cigarette smoke also.
Preserving room dcor, protecting furnishings, reducing maintenance and housekeeping and even hazards of fire from heating equipments are also some functions of air purifiers.
On the downside, air purifiers require constant maintenance and cleaning and can produce ozone and ions. The problem with these devices is that some purifiers clean dust but are not helpful with odors; others remove odors but don’t do much for the dust.
Research has proved that air purifiers might support in removing impurities and contaminants from the air but it is very complicated to free the air of odors and gases. For instance air purifier might remove the various particles present in tobacco smoke; it is not possible to remove even the gas compounds from it. Actually, such appliance will eliminate smoke but not the smell from the air around.
Everyone who considers purchasing an air purifier must know that such appliances come with their own limitations. A general rule as such for air purifiers does not exist. You must be fully aware of your requirement before you choose on the suitable device.
