Discover How Air Purifiers Help Eliminate Germs And Viruses

Nowadays, indoor air quality is more crucial than ever, particularly with the growing concern for people's health and safety. In general, air purifiers are a good approach to preserve your health because several ailments are spreading through the air.

But how exactly do air purifiers for germs and viruses work? This article will explain the general advantages of air purifiers, how they work, and what pollutants they can help you get rid of in your house.


How Air Purifiers Work

An air purifier can target the air in a specific room rather than the entire house. For example, most air purifiers only work in a small space, like one room or a particular portion of your home. However, some houses and businesses have separate whole-house air filtration systems from their HVAC systems, while others have them incorporated.

Nowadays, most portable air purifiers are made to remove both particles and gases. However, one filter cannot handle the full workload. Many air cleaners have numerous filters: one for particles, another for gases, and another for chemicals or odors.

Despite their variances, portable air purifiers generally function similarly. Fans in air purifiers bring air in and pass it through one or more filters. The filters pick up different types of dirt and then send the cleaner air back into the room.

Portable air cleaners vary in weight but can typically be transported from room to room. Some can be installed on a wall.


Types of Air Purifiers

  • Electrostatic Air Purifiers: Electrostatic air cleaners pick up dust and dirt and get rid of them.
  • Filtered Air Purifiers: One or more screens in filtered air filters catch dust and other things in the air.
  • UV light air purifiers: UV light air screens might be able to kill some germs and viruses.

However, researchers are concerned that electronic air cleaners may produce ozone gas and other hazardous pollutants that affect human health. As a result, filtered air purifiers are regarded as the most safe for use in the house.


Different Contaminants that Air Purifiers Can Help Remove

Particulate matter, or PMs, or airborne particles, is the name for most contaminants. Here are some possible indoor air pollution causes and how air filters can help.


People who already have breathing problems, like asthma or allergies, can get symptoms from allergens. Infestations of indoor places, like your home, are common and can be brought on by:

  • Pet dander: These are small and flaky skin or hairs that come from cats, dogs, birds, and other common house pets.
  • Animal dander from involuntary infestations (rats and mice): Similar to pet dander, but much more concentrated and unpredictable. According to research, 75% to 80% of homes in the United States contain detectable mouse allergens.
  • Cockroaches: During their life cycle, cockroaches lose substances like allergens, chitin, endotoxins, and more.
  • Dust mites: Microscopic mites that feed on people shed skin and do well in damp places. Based on research, 30% to 60% of children with asthma are allergic to dust mites, and their symptoms intensify when exposed.
  • Pollen: An allergen that comes from the outside and can get into rooms through doors, windows, and other air flow systems.

Pollen, house dust mite (HDM), and dog dander are just a few of the indoor allergens that can be reduced with the use of a high-efficiency particulate air (HEPA) air purifier, according to one study. However, not all studies reach the same conclusion regarding dust mites and animal dander in particular.

Dust mite allergens travel on bigger particles that swiftly settle to surfaces, making them impossible for air cleaners to capture. Animal allergies and pollen were also shown to decrease greatly when air cleaners were used, according to the report.

Gaseous Pollutants

Gaseous indoor pollutants could include the following:

  • Inorganic gases are things like carbon monoxide and nitrogen dioxide
  • Organic compounds that do not have a physical attachment to particles
  • Ozone

To filter gases, use a portable air cleaner equipped with an activated carbon filter or other gas-removing filter. HEPA filters are often poor at removing VOCs. In addition, some air cleaners are exclusively designed to remove certain types of gasses or VOCs.

Many air purifiers claim to minimize VOCs in the house. However, when the American Chemical Society examined four consumer-grade portable air cleaners that claimed to remove VOCs from indoor air, researchers discovered that the actual VOC removal was negligible.

Furthermore, it was found that some air cleaners "cleaned" the air but added more VOCs and other pollutants that are known to be bad for people's health. To get an air cleaner that can eliminate the VOCs you want to eliminate, carefully read the box or label.


Mold can be dangerous to people with asthma and other lung disorders. As a fungus grows, mold shows up on wet surfaces and moves to other areas. Its presence implies an issue with excessive moisture.

Mold releases spores into the surrounding air. You could develop a mold allergy if you come into contact with mold or breathe in these spores. Some symptoms include sneezing, mouth and nasal pain, red or itchy eyes, and a runny nose.

The Environmental Protection Agency (EPA) says that portable air filters don't get rid of mold. They might eliminate some mold germs, but they don't kill the mold itself. To do so, you can remove the extra moisture and clear away the mold.


Indoor smoke can originate from a variety of sources, including:

  • Tobacco products include cigarettes, cigars, and other smoked drugs like marijuana
  • E-cigarettes or vaping
  • Leaving cars, buses, and other vehicles to idle
  • Incense
  • Fireplaces and stoves that burn wood

However, an air purifier for smoke is ineffective at removing nicotine from indoor air, according to one study. HEPA air purifiers are good at getting rid of small particles in the air, but they can't get rid of the gaseous parts of smoke, like nicotine, because they don't appear in particle form.

Air purifiers can help with brief interior smoke from landscape fires, but they won't protect you from marijuana's major and secondary health dangers. Instead of using an air filter at home, you should just stop smoking in your homes or inside vehicles. A high-efficiency particulate air (HEPA) filter could help reduce smoking particles if this isn't possible at home.


How Air Purifiers Can Improve Your Health

According to the World Health Organization, taking in dirty air in your home can make you more likely to get these diseases:

  • Cardiovascular illness
  • Chronic obstructive pulmonary disease (COPD)
  • Lung cancer
  • Neurological disorders

The EPA says there is evidence that portable HEPA air cleaners can improve heart health, ease asthma and allergy complaints, and do other things. However, the benefit may be minimal, and other factors may be also at play.


Benefits of Using Air Purifiers in Home

The advantages and disadvantages of air filters depend on the same things that make them different, such as:

  • Type and number of filters
  • Clean Air Delivery Rate (CADR)
  • Targeted pollutants
  • Regularity and suitability of the device's usage

But here are some reasons why you should have an air cleaner in your home:

  • Allergies: An air filter for allergies can help you deal with your allergy issues better. They work by making the air in your home less full of allergens.
  • Animal dander: Some houses have problems with pet dander, like dogs, cats, or birds.
  • Asthma: Pollen, smoke, and dust can cause asthma, but air filters can help reduce symptoms.
  • Dust: Most high-efficiency particulate air (HEPA) screens can trap dust that is 5 microns or less. Your air purifier may lower the number of these particles.
  • Particulate matter (PM): Indoor PM (those with smaller particles) concentrations can be cut in half or more with the help of a HEPA air cleaner with enough CADR.
  • Viruses: Certain air filters can reduce the amount of virus-carrying particles in the air. This entails being able to remove particles that range in size from 0.1 to 1 micron, according to the EPA.


Safeguard with Air Purifier for Germs and Viruses 

Maintaining high indoor air quality should be a primary priority. That's why air purifiers are so important for making your environment healthier. Air purifiers are a good way to keep the air in your home, office, school, or healthcare center safe and clean.

An excellent air purifier can fight airborne pollutants, so you should buy one. With clean air, you can create a healthier and safer indoor environment for yourself and your loved ones.
