Air Up There – The Real Technology of Air Purifiers

Air purifiers are appliances that aid in removing pollutants from air. They are highly helpful and effective devices for people who suffer from asthma or allergies. With the power to clean the air that you breathe at home, most people simply don’t have any understanding on how air purifiers really work.


Though some think that you are only going to need air purifiers to keep you and your family from lung diseases, there is actually more to it than that. Learn how the machine works, what are the myths and truths behind air purifiers, and how you should be using them.

How they work

Here’s the idea behind the technology of air purifiers: no matter how much you clean your home, you cannot rid the air completely of allergens and other airborne irritants. Air purifiers are devices that are designed to clean the air in your house and improve the quality of air you and your family breathe. Using filters to rid the air of pollutants and allergens, like pollen, mold and pet dander, these machines also clean the air from other harmful particles, odors and irritants, such as cigarette smoke.

Air purifiers use HEPA (high efficiency particulate air) filters that aid in cleaning the air around it, ridding of contaminants and impurities. 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.


Air purifiers actually clean the air around you, purifying it by removing microns of 0.3 and larger size to render it almost dust-free. Some purifiers are designed taking into consideration people who suffer from asthma. These purifiers can make the air free from all kinds of particles and other impurities that cause allergies, so that you get to breathe pure air as naturally intended. The best air purifier for allergies is not difficult to find as a lot of suppliers are putting focus on machines that target allergens at home.

However, there are still limitations for air purifiers, especially when people don’t understand how they work, and still believe in myths behind these machines:

Air Purifiers Aren’t Magic Vacuum Cleaners

The most common misunderstanding is thinking that air can literally lift the dust off all the surfaces of your furniture so that you will never have to dust again. If that was the case then the fan in an air purifier would be so strong that it would create a dust storm in your home. Exactly the opposite of what an allergy sufferer would want. As such, you still need a good HEPA vacuum cleaner and microfiber dusting cloth to dust your furniture and floors.


Air Purifiers Aren’t Home Deodorants

A surprising number of people think that if they have an air purifier, it gives them a get-out-of-jail-free card to not empty the cat litter, leave a dirty clothes hamper or rotting food in the kitchen for months on end, while expecting an air purifier to pick up the slack. Air purifiers only work for odors if they have several pounds of high grade carbon in them. At the end of the day, good hygiene and removing the cause of the odor are still the best solutions.

Having an Air Purifier is an instant relief to allergies

An air purifier is only part of your allergy control program.  The problem is that some allergens like pollen are heavy, and fall to the floor or furniture before an air purifier has time to catch them. Some remedial actions require clean up and rearranging your home environment to be more allergy friendly; others require the use of allergy relief products, such as a steam cleaner for chemical free cleaning, or washing sheets in hot water above 140º.
