How Does an Air Purifier Work?
In America alone, it is estimated that $250 million is spent annually on home air purifiers. They work in different ways and come in many shapes, sizes and even ones that resemble some of your child’s favorite characters. But how bad is your home’s air quality, and how do air purifiers actually work?
The Facts On Air Quality
Allergy and asthma sufferers understand the importance of keeping the air in their home free of dust particles and bacteria. The air inside your home is continually being contaminated by elements such as mold, dust and dirt particles circulating throughout your home by your central air system, pet dander, outside pollens blowing in and attaching themselves to carpets and furniture, cigarette toxins and more.
The air outside your home is commonly healthier than what is inside because pollutants are concentrated in the confined area of your home and not blown about as they are in the large open areas of the outdoors.
The Different Types of Air Purifiers And How They Work
Many systems are simply air filters. They are part of you homes HVAC system and push all the air circulating throughout your home through a particle removing filter. It filters the air and prevents dirt and dust build-up in your heating and cooling system.
Placing different types of filters in each room’s air return vent stops allergens and other particles from passing through and into the air. These filters can be made of fiberglass and other synthetic fibers, each having its own density for different levels of impurity entrapment.
Ionizing purifiers create ions, which are charged molecules. They use a method called corona discharge, which is a powerful electrical field. Molecules receive either a positive or a negative charge and become attracted to one of two metal plates with opposing charges, drawing them from the air.
A process called adsorption, not to be confused with absorption, is also used in air purifiers. Porous substances such as activated charcoal attract and trap larger particles into its pores.
Using ultraviolet radiation is another form of air purification. Air passes through the UV light, which sterilizes it, removing harmful bacteria and other germs.
How Do Air Purifiers Help My Home And Family?
Air purifiers do just that, they purify the air in your home by removing dirt, dust and other allergy-causing particles from the air. Using a high-efficiency particulate air (HEPA) filter will allow your system to trap at a minimum, 90 percent of the particles passing through it.
Trapping and keeping contaminants and other elements out of your air also reduces the amount of dust and dirt that will collect on floors and furnishings, making it easier to maintain a cleaner, healthier home.
