Do Air Purifiers Help with Dust? What You Need to Know

There are many more things in the air than just oxygen. Indoor air is especially full of dangerous allergens and dust. These particles and germs can irritate our eyes, noses, and throats.

Air filters are made to deal with these problems, and they eliminate harmful pollutants from the air. However, a few things can affect how well your air filter works. Let’s find out how well air filters work and what other things you can do to improve your home’s air.

What Are Air Purifiers?

A study from the Environmental Protection Agency (EPA) air inside our homes is five times more polluted than outside air. Air purifiers are specially made to remove any pollutants and clean the air in your home from smells and things like smoke, dust, and allergens. Do air purifiers remove dust? Different types of air purifiers are used to eliminate different kinds of pollutants. They also come in different models and different shapes, sizes, and square footage.

There are different types of air purifiers, but their main purpose is to filter the air by passing it through one or more internal filters. These filters catch dust, allergens, mold, pet hair, bacteria, and other particles in the air.

How Do Air Purifiers Work?

As dust particles move through the air inside your home, your air purifier pulls the air inside your home in an air purifier by fan, and then the filters eliminate most of the harmful pollutants. It passes through the filter and comes out from the other end clean and refreshing with fewer contaminants and bacteria in it.

So filters are the most important part of an air purifier. Most air purifiers use a high-efficiency particulate air (HEPA) filter, that can catch 99.9% of particles that are 0.3 microns or smaller. Do air purifiers remove dust? Different houses have different sources of pollution and sizes of dust particles, but most of them are no smaller than 0.3 microns. HEPA filters are best to remove small particles.

Some air purifiers have extra filters, like odor filters and pre-filters. These filters can be washed and used again to eliminate pollutants. Before buying an air purifier, ensure you have a considerable amount of knowledge about different kinds of air filters. This way, you can choose the air purifier that best suits your needs.

Do Air Purifiers Remove Dust?

The answer is yes. Most air purifiers eliminate up to 99% of dust from the air inside your home. However, air purifiers are not the only answer to bad indoor air quality.

Many air purifiers on the market promise to remove most pollutants from your indoor air, including dust and allergens. However, the success rate of an air purifier is determined by other criteria. For example:

  • Positioning your air filter is important. Some air purifiers have a larger square footage. If the position of your air purifier is in a high-traffic location of your home, it will capture more pollution particles because more air is coming into the filter.
  • You should also pay attention to the filters in the air purifiers you are using. Many experts recommend that patients with respiratory disorders use an ASL—or AAFA-certified air purifier.

Other Ways to Get Rid of Dust in Your Home

The term “dust” refers to more than just the thin layer of gray film that covers your furniture and appliances. Dust contains both indoor and outdoor pollutants, such as dead skin cells, pet dander, and other toxins that can be harmful to you, like pollen and smoke. It doesn’t matter how many dogs you own, at times you leave your windows open or clean your home, there is still some dust mixed with allergens are there in your home.

Air purifiers can remove dust, allergies, and other pollutants from the air, but there are many other ways to clean and improve air quality.

  • Frequently sweep, mop, and vacuum the floor.
  • Have a regular washing schedule for all your bedding, including blankets and pet beds.
  • Regularly clean your carpets, rugs, and other fabric furniture. If you want easier-to-maintain furniture, then replace the cloth with leather or vinyl.
  • Open the windows and doors occasionally to let in some fresh air, because the air quality inside is usually lower than outside.
  • Keep the humidity within the house below 60%.

How Air Purifiers Pass Dust The Test?

Do air purifiers remove dust? How do I know?  Is it possible to test an air purifier for dust? How do I know how much dust the air purifier catches from the air and see how well it works? An air purifier with a HEPA filter has a 99.97% efficiency rate but it still can’t remove all the dust, Removing dust from the HEPA filter depends on its model and filter. Not all of them need to be as “efficient” to remove dust from the air.

This filter is great for capturing particles but it can’t do anything about gasses. HEPA filters only capture contaminants but dont eliminate them. This means any mold or bacteria trapped in the filter can proliferate before being discharged back into the air.

Why the dust in the air is important

You will learn that dust isn’t just dusty bits of dirt from the outside; it’s made up of a bunch of different things. You’ll be shocked at where dust comes from. Dust can be annoying if you have allergies, asthma, or other breathing problems because it can hurt your eyes, nose, or throat.

Do air purifiers remove dust? There’s a good chance you are allergic to dust if it makes your asthma or allergies worse. Small pieces of dust often float in the air, which worries everyone. If the pieces are small enough, they can get into the lungs and hurt your health.

There’s more to dust than you think.

You were wrong if you thought that dust was just dirt or dead skin cells. 

According to Layton and Beamer (2009), the dust in your home is mostly made up of the following:

  • Particulate matter from the air outside
  • Organic matter
  • Scientists legally define “organic” as carbon-based compounds and organic matter comes from plants and animals.
  • Soil that gets tracked into the house

This living matter has the following:

  • Dull pet hair
  • Particles of skin
  • Allergens in dust mites
  • Food scraps
  • Parts of insects
  • Mold Pollen

Pamela Beamer told NPR that the indoor dust parts can include things like carpet or clothing fibers.

Another expert on dust, Andrea Ferro, told NPR that some dust particles are so small that they can float in the air, some are big enough to land on the floor, and some are made up of just one inorganic or organic compound.

Frequently Asked Questions

Air purifiers, especially those with HEPA filters, are good at catching dust like pet hair, pollen, and mold. However, they might not get rid of gases or some chemicals.

It’s best to follow the maker’s instructions about filter care. Usually, you should check them often and change or clean them every 3 to 6 months, as instructed.

Yes, air purifiers can improve allergies and asthma symptoms by removing dust mites, pollen, and pet hair from the air, making the air inside better to breathe.

Air purifiers’ energy consumption can vary depending on their size and filter type. However, many new ones are made to use less energy.

If you follow the manufacturer’s instructions, air purifiers are usually safe to use. However, they should be kept away from water to avoid shocks, and the filters should be cleaned or changed often to keep the air clean.

Conclusion

Do air purifiers remove dust? Air purifiers remove dust, allergies, and pollutants to improve indoor air quality. HEPA filters catch dust, but air purifiers may not eradicate all contaminants, especially gases. Regular cleaning, bedding washing, and humidity management help air purifiers create a healthier house.

By understanding dust composition, you can tell the importance of indoor air quality in reducing allergies, asthma, and respiratory diseases. Thus, air purifiers must be used with other cleaning methods to remove dust and clean indoor air quality.
