The 7 Best Air Purifiers of 2022

There is something in the air and it isn’t good. Consumers are buying air purifiers as if their lives depend upon them, due to wildfires and coronavirus. Although they aren’t the only way to improve your health and wellbeing, air purifiers can make it easier for you to breathe.

Kenneth Mendez (president and CEO of the Asthma and Allergy Foundation of America) says that air purifiers are used to remove small particles or air pollution from the air we inhale. These tiny particles can be small and irritating to the lungs. They can also trigger allergic reactions if inhaled. These pollutants can be found almost anywhere. Mendez noted that the main sources of pollution are “cooking,” automobile emissions, dust, and burning of coal.

It can be difficult to shop for an air purifier due to all the options, terms and confusing numbers. Dr. John McKeon is the founder and CEO of Allergy Standards Limited (ASL). He suggests that shoppers look for some basic things when shopping for an air purifier.

Find one that has a high-efficiency particulate filter (HEPA). McKeon states that a device with a HEPA-filter is a good option for people suffering from asthma and allergies. It can remove 99.97% (including pollen spores, dust mites, and bacteria) of particles measuring 0.03 micrometers in size. McKeon suggests activated carbon filters to remove odors and gases. Activated carbon filters can be combined with HEPA filters for enhanced filtration. McKeon also mentions clean air delivery rate (or CADR), which McKeon states “indicates how much filtered air an air cleaner delivers, with separate scores to smoke, pollen and dust.” The cleaner purifier filters the air faster if the CADR is higher. However, it is important to remember that the CADR shows the purifier’s efficiency at its highest fan speed and the loudest setting. These are the top-rated air purifiers in 2022.

Do Air Purifiers Work?

Air purifiers do work, in short. Air purifiers remove particles from the air that could cause allergies and other health problems. They also improve indoor air quality. However, they are not a panacea for perfect indoor air quality. They can’t remove all unwanted particles from your home, especially those that stick to hard and soft surfaces. Air purifiers can have a significant impact on your respiratory health.

What is the working principle of an air purifier? 

Air purifiers use filters and fans to trap particles in the air so you don’t breathe them in.

Mendez explains that some air cleaners trap allergens such as pollen and pet dander within their carbon or media-based filters. Other air cleaners use an electrostatic filter to give the particles an electric charge. The particles stick to the metal plates of the filter, which can be washed to remove them.

Different filters can be used to trap large or small particles and eliminate odors. You should be on the lookout to find purifiers that release oxygen. This can cause respiratory problems for people with asthma.

Are Air Purifiers Good for COVID-19?

This is a difficult question. True HEPA filters are effective in removing COVID-19 from the air. However, COVID-19 can only be spread by direct contact. Although an air purifier may be effective in filtering the coronavirus-infected air, it won’t make you immune to the virus if you are sitting next to someone with the virus, mask off. The Environmental Protection Agency explains that HVAC filters and portable air cleaners are not sufficient to protect against COVID-19. Air purifiers are more effective when combined with social distancing, wearing masks in public and other measures to protect your family against the virus.

Can Air Purifiers Help with Wildfire Smoke?

Air purifiers are able to remove both cigarette smoke as well as wildfire smoke. Fine particles pose the greatest threat to your eyes. They can cause irritation, stinging, and worsen respiratory problems. According to the Environmental Protection Agency, smoking can also lead to chronic lung and heart diseases.

McKeon states that if you don’t have an HVAC system equipped with a high efficiency filter, a portable cleaner or purifier may be recommended. This will remove fine particles from your air and reduce your exposure during wildfire smoke events.

Air purifiers that have carbon filters can remove smoky smells, which can cause irritation to the nose and throat. The Environmental Protection Agency warns against air purifiers that emit ozone. This can lead to indoor air quality problems. The California Air Resources Board maintains a list of certified air purifiers that do not produce excess ozone. It can be found there.
