Cleaning up those dust bunnies that hide underneath your couch may be no big deal, but getting rid of the dust that hangs in the air is another story entirely. If you’re able to rid your surfaces of dust, that’s great, but most homes are always going to have some dust particles floating in the air.

If you or one of your family members is sensitive to dust and you don’t know how to cleanse the air of the stuff, then an air purifier may just be able to help. Let’s take a look at the effects of air purifiers in airborne dust.

So, Let’s Cut to the Chase – Do They?

To give the shortest answer, yes, the majority of air purifiers for sale these days are made to remove large particles of dust from the air. Many purifiers make use of mechanical filtration, which is a method that is used to capture air contaminants in filters.

The particles will either attach to the filter or become trapped within the fibers of the filter. Most mechanical filters will either be pleated or flat. An example of a flat filter is a simple furnace filter or the filter in your HVAC system, which is able to trap small amounts of dust in the air. This is, however, too basic of an example, and these filters cannot be used with air purifiers.

Flat filters are also sometimes electrostatically charged, which makes them more ‘sticky’ for dust particles.

Air Purifiers – What They Need to Do

Air purifiers that use mechanical features are ‘good’ if they are able to capture minuscule particles inside of the filter’s fibers. Dust particles are generally smaller than the width of a human hair, and can sometimes be so small that they enter the human lungs, which can be a serious health concern.

There is another, less common air purifier that is specially made to trap particles in the air – electronic air cleaners. These come in the form of ionizing or electrostatic air purifiers and work by transferring electric charges to contaminant particles either to trap them on metal plates or force them to settle on surfaces close to the purifier.

This may sound all fine and dandy, but electronic purifiers have one fatal flaw – they can produce ozone, which is a harmful irritant to the lungs. Furthermore, trapping dust in an ozone generator is not going to work.

What to Do About Dust When You Don’t Have an Air Purifier

Using air purifiers to remove dust is a great method, but you should not neglect to control the source of the dust. This is essential, as large particles of dust can settle on your flooring where they will not be able to be collected by a purifier. These are also particles that are too big to float into the air and will simply continue in the constant cycle of becoming disturbed, rising up into the air, then settling down again onto the floor and your home surfaces.

Source control is precisely what you think it is – destroying the source of your dust. This can be done through dusting and cleaning your house, though you are going to have to be cautious about injecting more dust into your home’s air. It’s also a great idea to replace the filters on your HVAC as frequently as necessary.

We also strongly suggest that you take preventative measures to stop dust coming into your home from outside. You can do this by changing clothes when you get home or wiping down your pets before they come inside. This will significantly reduce the volume of exterior particles that enter your home – particles like mold and pollen.

Why Care About Airborne Dust Anyway?

Dust isn’t simply soil floating around in your air and settling on your floors – it’s a concoction of different materials. It can irritate the eyes, nose, and throat, and become extremely problematic for people who have asthma, allergies, or other respiratory illnesses.

If your allergies or asthma become worse because of dust, you are likely allergic to dust. The most worrisome part for everyone is that tiny dust particles can often float around in the air in your home, and if they are large enough, they could enter the lungs and cause health issues.

Dust can also cause dust mite droppings, which are a common allergy trigger. When you inhale dust with this substance, you could experience an allergic reaction. What’s worse is that dust mites feed on skin particles that are present in dust.

Wrapping Up

If you want your home’s air to be as pure as possible, be sure to get your hands on an air purifier. And remember: don’t neglect source control! Dust can be a cause of many health problems and an air purifier can be a very simple solution.
