Purifiers are excellent when it comes to cleaning contaminants and particles from the air.
They even go as far as removing foul odors and reducing air-borne bacteria and viruses. However, do air purifiers reduce dust, too?
In this article, we’ll look at this significant question and why it’s vital to remove dust from your home.
Do Air Purifiers Reduce Dust?
Many purifiers hold a True HEPA filter as one of the many layers inside. This captures most pollutants, one of which is dust. Studies have shown that this filter can remove up to 99.97% of dust particles that are 0.3 microns in size.
These tiny particles are the ones that end up in our lungs and are the most dangerous to our health. The dust lingers in the air or settles in your carpet or curtains, sometimes hidden deep within fabrics. One slight movement dislodges it into the air, which is where the purifier draws it in to remove it.
How an Air Purifier Can Help Reduce Dust
The reason a purifier is so effective against dust is due to the many filters on the inside. While the activated carbon layer mainly focuses on foul odors and VOCs, the other three layers are effective against dust. Let’s take a look at each one and how they function.
Sometimes purifiers will have a grille or fabric layer on the outside. It isn’t merely for decoration. This section acts as the first filter and the initial defense, removing the largest dust particles before they even enter the device. You can generally wash these clean.
Before the dust finds its way to the HEPA filter, they’ll encounter a pre-filter. The netting or mesh is larger, capturing the particles that manage to escape the initial layer. You’ll also be able to wash this filter, but it may require replacement from time to time.
The HEPA filter is the ultimate item that protects against dust, mostly because it deals with contaminants that are 0.3 microns in size. It’s the final layer in the purifier, after which clean air goes back into the environment through the exhaust. This filter may become clogged and leave a foul smell from the machine, so make sure you maintain it regularly.
What is Dust, and Why Should I Get Rid Of It?

Have you sneezed near cats and dogs, or been told that you’re allergic to their hair? It’s a common misconception and one that we’ll quickly clear up. The dander and saliva have proteins that may be triggering your allergies, not the actual substance.
It’s this component that travels with dust at times, causing you to sneeze when the dust reaches your nasal passages. If you don’t remove it from your home, it can irritate your lungs and lead to you becoming sick.
Mites make a home on fine dust particles when there’s loose skin to be found. After consuming this delicious meal, they often leave droppings that float with the dust in the air. It’s a common cause of allergic reactions, causing issues with your breathing.
Pollen is the number one irritant for asthmatics. When flowers bloom, the strong winds sometimes carry fine pollen particles in the air into your home. It can cause your chest and trachea to swell up, which is something a purifier is excellent at resolving.
People and pets love to walk soil into the home, which sometimes lodges into the carpet. As you traverse your house, you break these large particles into smaller ones.
