What Are Dust Particles Made of?

When you hear the word dust, you probably visualize grey-colored dirt settled on various surfaces at your home. Contrary to popular belief, dust isn’t just small particles of dead skin cells and dirt. It’s far more complex than containing different types of particles originating from a wide range of sources!

Dust usually generates outside and finds its way into our homes via air. Organic materials like mold spores, pollens, soil particles, dust mites, insect body parts, etc., are commonly regarded as outside dust that we can find inside.

On the other hand, dust can also originate from indoor elements. If you’ve got pets, your room will naturally fill up with pet dander and fur. Hair fiber, dead skin cells, and food debris are also commonly found inside households.

Why Should You Reduce Dust?

Dust doesn’t just make your room look dirty; it can negatively affect your health, especially your respiratory system. While most of the dust particles are harmless, some of them can be detrimental to your health.

The effect of breathing in dust-filled air can range from slightly irritating eyes, nose, and throat to more severe problems like asthma, allergies, and even cancer! Dust often contains dust mites that can trigger allergic reactions to make your life hellish.

As you breathe in an environment loaded with dust, many of the harmful elements found in dust will find their way into your lungs. After years of such exposure, your respiratory system will take a hit, and you’ll start suffering from a wide range of health conditions. You can prevent all that by making your air cleaner.

So, How Does Air Purifier Reduce Dust, and Does It Work?

The tiny particles of dust keep floating in the air inside your home until they find a suitable surface to settle in.

Now, if you’ve got an air purifier set up inside, those particles won’t get to do what they do best. That’s because the device is designed to trap the pollutants before they get a chance to settle, allowing you to breathe in fresher air. Many air purifiers come integrated with mechanical filtration systems to capture the dust particles. The most effective filter is known as the true HEPA filter, commonly found in high-quality products.


Now, this filter offers remarkable dust-capturing performance as it can trap tiny particles that are as small as only 0.3 microns. You won’t be able to see them with your naked eyes, but any air purifier fitted with a true HEPA filter will be able to capture them with ease! It will offer 99.97% efficiency.

An air purifier pulls the air inside and causes it to pass through the filter before circulating back into the room. The filter captures most of the air pollutants and prevents them from going back. So, the air that comes out of the purifier contains significantly fewer dust particles.

As a result, you get to breathe in an air that is much more pleasant, safe, and clean! While air purifiers cannot obliterate the dust, they can definitely get rid of most of the pollutants!
