Dusty Table

Do you have a dust mite allergy?

Or are you just tired of dust collecting in your home and want it to stay cleaner?

If either of those is the case, then you’re probably wondering, “Will an air purifier remove dust?”

If you are, then you landed on the right page.

In this post, we’ll answer that exact question so you can determine if an air purifier is a good product to buy or not.

We’ll first start with the short answer so you know what’s ahead, then we’ll go more in-depth on how do air purifiers reduce dust.

Will an Air Purifier Remove Dust or Help with Dust Mites?

Yes, an air purifier can remove dust and reduce dust mites. To be effective against dust the air purifier must have a HEPA filter. This filter removes microscopic particles that form dust before it has time to accumulate. The less dust there is, the fewer dust mites you’ll have to contend with.

A More Detailed Answer:

First, What is Dust?

Dust is so much more than just dirt, and it’s one of the most common irritants on the planet. To make matters more complicated, most dust particles are microscopic.

The tiny size of dust makes it very hard to get rid of by regular dusting or vacuuming. It also makes it easy for you to stir these particles up when you clean your house.

Dust particles are made up of dozens of different things. Because of this, dust won’t ever truly go away no matter how much you try to do a deep clean.

Common sources of dust include pet dander, hair fibers, fabric fibers, carpet dust fibers, construction materials, human skin, outdoor elements, and much more.

Second, Do Air Purifiers Reduce Dust?


Simply put, an air purifier is designed to take the dusty air and turn it into air that is clean and healthy for you to breathe.

So, how do air purifiers reduce dust so well?

Inside the best home air purifier units, you’ll find an electric fan that draws air into the unit and then forces the dirty air toward a filtration system as a way to clean it.

There are two main layers of this filtration system that this air will pass through. The first filter layer that the dust hits contains a larger more coarse material that traps the bigger dust particles, called a pre-filter air filter. Anything that is small enough to slip through this pre-filter goes to the second part of the system, the HEPA filter.

HEPA stands for High-Efficiency Particulate Air, and this is a very dense layer of material that traps even tiny dust particles and keeps them out of the air you breathe. An air purifier with a HEPA filter can filter out and trap up to 99.97% of dust particles. That’s why it’s considered the most best air filter for allergies.

To keep your air purifier operating at peak performance you’ll need to change or clean these filters every couple of months unless you buy an air purifier with a washable or permanent filter.

The best air purifier with reusable filter can work to remove dust particles from the air, but it’s not going to be as efficient as a device with a replaceable HEPA filter. That’s because the filter material is not as dense to trap microscopic pollutants.

The difference in efficiency for a reusable HEPA filter is around capturing dust particles as small as 2 to 5 microns in size versus 0.3 microns for a replaceable HEPA filter.

Third, Will an Air Purifier Help with Dust Mites?

Now, if your air purifier traps dust, the next logical question is, “Will an air purifier help with dust mites?”

Again, the short answer is yes.

Dust mites feed on the dust particles that float around your home. If you reduce the number of dust particles indoors, the dust mites will have less to feed on. You should start to notice fewer and fewer dust mites around your home the longer you use your air purifier and keep the filtration system clean.

This is great news for anyone with a dust mite allergy or other respiratory issues like asthma and COPD.

Lastly, How Do You Find the Best Air Purifier for Dust?

Now that you know how well an air purifier can tackle dust and dust mites, you’re probably curious to find out which products are best made for dust.

Summary – Can an Air Purifier Remove Dust and Dust Mites?

The answer is yes. Here’s a recap of what you learned:

  • Dust particles are one of the most common things on the planet, and dust mites eat dust particles.
  • Dust is extremely hard to get rid of via cleaning methods only because it comes from multiple sources.
  • An air purifier will cycle your home’s air through a coarse filter first and then a HEPA filter to trap up to 99.97% of microscopic dust particles.
  • Filtered air is healthier for you to breathe, especially for people with allergies or respiratory conditions.

Now you know the answer to the question, “Will an air purifier remove dust?”
