What Type of Air Purifiers Are Best for Fighting Viruses? Air Purifiers Can Remove Many Pollutants & Bacteria From the Air. Continue Reading to Discover All the Benefits…

The importance of clean air is something that the medical community has well understood for decades.

Cleaner air means cleaner lungs, and cleaner lungs mean better health outcomes and a happier life.

But what about viruses?

Air purifiers can also help fight against viruses in your home or office with their efficient filtering systems.

Through this article, you’ll discover:

    Let’s take a deeper look into the world of air aurifiers for some astonishing facts on viruses vs. air purifiers…

    Why Does Air Quality Matter?

    The first thing to understand is the importance of air quality1.

    The World Health Organization reports that almost 7 million people die every year from diseases associated with indoor and outdoor air pollution2.

    This means it’s vital to maintain clean living spaces to keep these pollutants out.

    Air purifiers operate by filtering particles like dust, smoke, pet dander, and pollen before release into your home or office space.

    So they’re an ideal solution for those looking for a healthier environment as they remove these particles.

    COVID-19 Airborne Transmission

    We were made to believe that COVID-19 can only be transmitted through close person-to-person contact with saliva or respiratory droplets.

    But many experts think that these aren’t the only modes of transmission.

    Get this…

    239 scientists wrote an open letter to the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), and other health agencies regarding the spread of the coronavirus.

    The letter suggested that an infected person can produce aerosolized micro droplets that spray from the mouth and float into the air.3

    In a CNN interview, Donald Milton, a professor of environmental health at the University of Maryland, said, “They don’t want to talk about airborne transmission because that is going to make people afraid.”

    This is exactly why wearing a mask is very important when controlling the spread of not only COVID-19 but also the common flu and some respiratory diseases.

    Choose the Right Air Purifier

    HEPA Filtration Is Effective but Not Quite

    The Governor of New York City, Andrew Cuomo, advocated the use of high-efficiency air filtration systems in malls to trap the COVID-19 virus.

    Still, the question lingers…

    Is it possible to capture the virus through the use of an air purifier?

    Various air purifiers on the market are equipped with a HEPA filter.

    This filter effectively removes at least 99% of dust, pollen, mold, bacteria, and any airborne particles that are 0.3 microns in size.

    Some HEPA filters trap ultrafine particles as small as 0.01 microns.

    High-end HEPA Air Purifiers can eliminate particulates 0.01 microns in size by using a patented air purifier technology called Photocatalytic Oxidation or PCO.

    This method uses a catalyst, germicidal UV light, and other advanced components to effectively kill airborne viruses and bacteria.

    The coronavirus is approximately 0.125 microns in diameter which are up in the alley of particle sizes that a highly efficient HEPA filter can capture.


    Before you storm out and buy one, remember that an air purifier shouldn’t be considered the first line of defense against the COVID-19 virus.

    As of June 2021, the CDC said, “COVID-19 is thought to spread mainly through close contact from person-to-person,” through “respiratory droplets produced when an infected person coughs, sneezes, or talks.”4

    So, wearing face masks is still king!

    Air Quality Matters

    How Air Purifiers Fight Viruses

    Air purification systems filter out particles that cause many health problems, so it’s no surprise that they can help with viruses too.

    An air purifier is an effective way of killing airborne pathogens like the flu virus or a cold virus and bacteria and mold spores, which can lead to respiratory illnesses.

    Here’s the deal…

    An air cleaner removes 99.95% of the particulate matter from your air, and a HEPA filter can remove 98% of airborne particles like pet dander or pollen that might trigger allergies5.

    The filters also release negative ions, which produce positive health effects for those in the surrounding space.

    Air purifiers filter out pollutants and contaminants so you can enjoy the benefits of clean air.

    Clean and fresh air offers various benefits like strengthening your immune system and improving sleep quality.

    How Air Purifiers

    Benefits of Air Purifiers

    The benefits of air purifiers include:

    • Cleaner air.
    • Improved lung function and respiratory health.
    • A reduction in allergies caused by pet dander, smoke, or other particles.
    • A reduction in infectious disease.
    • A healthier environment for your family or roommates.
    • Improved air quality inside and out.
    • Air purifiers are great for achieving a healthy home environment for all those living there.
    • They’re very efficient, which means they save energy too.

    How Do Air Purifier Filters Work? 

    The filter works by trapping the particles and releasing clean air.

    The filters remove almost 100% of airborne mold, bacteria, fungi, pet dander, and smoke particles as small as 0.12 microns in size.

    The Activated Carbon Filter (ACF)6 is a common type in most HEPA filter systems today.

    This ACF eliminates organic gases, such as formaldehyde, from the environment.

    Keep in mind…

    These types of gas can cause eye irritation or aggravate allergies like asthma because they irritate tissues inside your nose and throat.

    The ACF also removes odors from the air caused by cooking, pets, or cigarette smoke.

    The particles in these smells range from 0.12 microns to 50 microns, so they would be removed much more quickly than those at .2 micron size.

    Last, Activated Carbon Filters remove chemicals such as benzene, a known carcinogen found in many household items like detergents and cleaners.

    These substances can affect your immune system7 over time if you’re exposed to them regularly.

    How to Use Your Air Purifier to Fight Viruses 

    Air purifiers are an efficient and effective way of fighting against viruses, but it’s important to understand how they work best.

    For example, HEPA filters must be replaced every 12-18 months for them to continue working at peak efficiency, which might not seem like a lot until you realize some models require filter replacement after just 6 months.

    Air cleaners should be cleaned regularly with the help of a clean cloth or vacuum cleaner attachment.

    This helps remove any dust build-up from furniture around your home or office space and prevents allergy triggers before they happen.

    Use Your Air Purifier

    What Air Purifier Features Should You Look For When Purchasing?

    The 4 key features you should look for in an air purifier are:

    • HEPA filter.
    • Electronic controls.
    • Ionizer8, is only necessary if allergies or asthma are present.
    • Long filter life for the best quality of air.

    In order to provide the best quality of air, it’s necessary for your home or office space to have an air purifier that has a HEPA filter.

    This will eliminate up to 99% of airborne particles such as mold and pet dander that can trigger allergies or asthma symptoms9.


    You should also look for features like electronic controls with auto-timer shut-offs if you want something more heavy-duty than a portable device.

    Last, keep in mind how often each type of filter needs replacing when purchasing your new unit, so you know what kind is right for you.

    If allergens are a big concern in your area, then choose an ACF model that removes both organic gases and odors from the environment.
