Clean, fresh air is important for your health and well-being, and if you’re like most people, you probably don’t give it a second thought until it’s taken away.

Lack of fresh air can cause a variety of problems, from asthma and allergies to nausea and headaches. And one of the best ways to get fresh air is to use an air purifier.

What is Dust?

Dust is tiny bits of matter that float in the air.

Dust is made up of different materials, but the vast majority of it is composed of small bits of organic matter (like skin cells and plant pollen) and inorganic matter (like dust mites, fibers and spores).

Dust can cause allergies and asthma attacks, and it’s also a major contributor to indoor air pollution. Dust can also contain harmful chemicals like lead and mercury.

Dust is more than just dirt or dead skin cells, as you may have previously believed.

The dust you’ll find in your home is made up of a variety of substances, including:

  • Soil that is tracked into the home
  • Particulate matter from outside air
  • Organic material

Plants and animals produce organic material (scientists use the term “organic” to refer to carbon-based compounds).

  • Skin particles
  • Food debris
  • Pollen
  • Mold
  • Pet dander
  • Insect body parts
  • Dust mite allergens

Do Air Purifier Remove Dust?

Our home is filled with small particles that float around in the air until they land on a suitable surface. Many of these particles will be captured by an air purifier before they have a chance to settle, making the air more pleasant to breathe and preventing the collection of dust on our tables, bookshelves, and other surfaces.

The short answer is yes, air purifiers remove dust.

A true HEPA filter is the most important tool for removing dust from the air. To protect Manhattan Project scientists from microscopic radioactive particles, HEPA filters were developed in the 1940s and gradually became utilized commercially in filters and vacuums because of their high efficiency at eliminating particles from the air.

With 99.97 percent effectiveness, a true HEPA filter can capture particles as fine as 0.3 microns, although it can also capture larger and smaller particles. Sizes smaller than 0.3 microns are the most difficult to catch and the most likely to enter the lung.

All the small particles floating in the air, including dust, are drawn in by an air purifier as it circulates the air in the room. Particles are caught in the fibers of the filter, preventing the air from flowing freely through it.

If inhaled, these dust-producing particles can trigger allergies or asthma attacks in those who are sensitive to them. The usage of an air purifier can greatly reduce the amount of dust in your home, even if it doesn’t eliminate all of the particles.

The Dangers of Dust

Dust is a major problem in many homes and it can be a serious hazard to your health. Not only does it make your home look and feel dirty, but it can also cause allergies, asthma, and other respiratory problems.

One of the best ways to combat the dangers of dust is to install an air purifier. These machines work to remove dust and other particles from the air, making your home a safer and healthier place to live.


The answer to this question is a resounding yes – air purifiers remove dust particles from the air. However, it’s important to note that not all air purifiers are created equal. Some are better at removing dust particles than others. So, when shopping for an air purifier, be sure to select one that is specifically designed to remove dust from the air.
