Air Purifiers FAQs: Do air purifiers help with dust?

While trees are continually cleaning outdoor air, indoor air needs the help of filters and purifiers to stay unsullied. While air purifiers are excellent at removing pollutants from the air, do air purifiers help with dust? Let’s take a look.

What Is Dust?

Before we can determine whether air purifiers remove dust, it can be helpful to learn what dust is made of. What appears to be a uniform gray substance, dust is actually made up of everything from soil and organic materials to skin cells, food debris, pet dander, and even insect parts. Most of us work to keep our homes dust-free for a variety of reasons, and now we can add the fact that dust is made up of nasty stuff to the list.

Do Air Purifiers Help With Dust?

Along with being a foul substance, dust can also cause respiratory problems and other illnesses, especially for people with existing health conditions and allergies. Reducing the amount of dust in the home is important for your overall health and the appearance of your home, but cleaning dust can be a tedious task.

The good news is that air purifiers are designed to attract and trap dust particles as small as 0.3 microns. For comparison, a single strand of hair is between 100 and 150 microns wide, so air purifiers are picking up most of the tiniest particles floating around our homes and settling on our surfaces. The process is simple, too: as air moves through the filter of an air purifier, these microscopic particles are captured and clean air moves into the living area.

Getting the Best Results

To get the cleanest air in your home, the filter of an air purifier must be changed regularly as a clogged filter will be unable to trap as many particles. A HEPA filter will also help ensure the cleanest air possible as their design is such that 99.97 percent of dust matter is caught. In fact, HEPA filters were designed to trap radioactive material in the air as part of the Manhattan Project so we can certainly trust them to remove most of the contaminants in our home’s air!

The Bottom Line

If you want cleaner air in your home, an air purifier will do the job. For the best results possible, choose a model that has the option for HEPA filters, and breathe easy when you’re at home.
