How Does an Air Purifier Work?
Air purifiers work by combining an internal filter and fan to pull in unwanted particles from the air in a specific room. The purified air is then circulated back into the room, and this filtration process repeats several times an hour, continually boosting indoor air quality. High-efficiency particulate air (HEPA) filters are particularly effective, capable of capturing 99.97% of airborne particles, including allergens, dust, lint, mold spores, bacteria, viruses, and pet dander.
Types of Air Purifiers
There are several types of air purifiers that use different technologies to clean the air. Based on your selection, the most relevant types of air purifiers for this article are:
HEPA Air Purifiers: These purifiers use HEPA filters, which are mechanical filters that force air through a dense web of fine fibers to trap particles. They are effective at removing both microscopic and larger particles when they’re suspended in the air.
Activated Carbon Air Purifiers: These purifiers use activated carbon filters to capture certain types of gases, including some odor-causing molecules. They are effective at removing odors, chemicals, fumes, smokes, and gases from the air but may be less effective at removing pollen, dander, dust, or mold from the air unless the model includes a HEPA air filter.
Ozone Air Purifiers: These purifiers generate ozone to eliminate odors and neutralize airborne pollutants. However, they can produce harmful levels of ozone, which can irritate the lungs and exacerbate respiratory issues. It’s essential to choose an ozone air purifier that meets safety standards and produces minimal ozone.
Ionic Air Purifiers: These purifiers use electrical fields to trap charged particles. They emit negative ions into the air, which bond with positively charged, airborne particles like dust, making these particles so heavy that they eventually fall out of the air. Some ionic air purifiers have electrostatic precipitators that trap positively charged particles to a metal plate inside the air purifier.
UV Air Purifiers: These purifiers use ultraviolet (UV) light to kill bacteria and viruses. They are effective at eliminating microorganisms but may not be as effective at removing larger particles like dust, pollen, or mold spores.
When choosing an air purifier, consider factors such as room size, specific health needs, maintenance, and energy costs. The best device will depend mostly on room size, plus your lifestyle and purification needs. For instance, if you live with a smoker, choose an air purifier that has a high Clean Air Delivery Rate (CADR) for tobacco smoke.
Choosing the Right Air Purifier
When it comes to purifying the air in your room, an air purifier needs to do two things. It needs a means of removing harmful particles and gases — typically done by a set of filters — as well as the ability to circulate most of the air in the room through those filters multiple times per hour using a fan. You’ll want to choose a device that does both of these jobs well.
The Environmental Protection Agency (EPA) recommends that all the air in your room be processed through your air purifier five times per hour. To help you determine if a given air purifier will work for your room, most manufacturers list a maximum or recommended room size, and some will even mention how many air exchanges for the space per hour. To be sure you’re finding the right air purifier for your space, calculate your room’s square footage by multiplying its width and length, then look for a Clean Air Delivery Rate (CADR) rating that is about two-thirds of that number.
Specific Health Needs
If you live with a smoker, choose an air purifier that has a high CADR for tobacco smoke. Similarly, if you suffer from seasonal allergies or have a constantly shedding pet, you may already be familiar with the positive benefits of an air purifier. Not only do air purifiers help lower airborne pollution like dust, pollen and particulates, but the best air purifiers can tackle smoke and toxic gases as well as helping to filter out bacteria and viruses.
Maintenance and Energy Costs
Since air purifiers should run regularly, if not all the time, you’ll definitely want to choose a model that keeps energy use to a minimum. According to the EPA, a standard room air purifier uses 450 kWh per year, which is more than some new refrigerators. Energy Star rated air purifiers need to be over 25% more efficient than standard models.
