Do Air Purifiers Get Rid of Dust? | Do I Need to Dust if I Have an Air Purifier?


dust accumulation

Yes, air purifiers get rid of dust and they are quite good at it. Air purifiers are able to get rid of the dust in the air because they capture it in the various kinds of filters that they use. Air purifiers with HEPA filters are the most likely to remove the most dust, but there are plenty of other filters that can also help to remove the dust from the air.

How Much Dust Can an Air Purifier Remove?

Air purifiers are great at removing dust from the air, in fact, an air purifier that has a HEPA filter can remove 99.97% of the particles in the air! In other words, that’s a whole lot of dust. But, HEPA filters are good at removing things other than dust as well. They can capture allergens and even some odors too!

If odors are a concern of yours, then I recommend finding an air purifier that has an activated carbon filter in addition to a HEPA filter. These can be very affordable and are oftentimes already a part of a lot of air purifiers that have a HEPA filter.

Now, back to the original question about dust.

Air purifiers, as I already said, are great at removing dust from the air. They can’t clean the dust out of your carpet, furniture, curtains, or anything like that. Because of that, there will probably be dust in your home no matter what you do. But, air purifiers can work to limit the amount of dust in the air you’re breathing. In the long term, air purifiers will limit the amount of dust in your home as well, but that will be more easy to achieve if you vacuum regularly.

I had to make the distinction about air purifiers only taking care of the dust in the air because there are people who think an air purifier takes care of their need to clean their home entirely. No, these people aren’t insane, they’re on the right track, they just went to the extreme.

In reality, you probably won’t have to clean things as often as you did in the past, if you get an air purifier. All that dusting and all those random odds and ends that you picked up to try to dust quicker and better will be used a lot less when you buy a good air purifier.

But, that isn’t to say that you won’t have to ever clean your home again. You’ll still have to vacuum. You’ll still have to do your laundry. You’ll still have to dust. But, you might be able to get away with dusting and maybe even vacuuming a little bit less often.

Do Air Purifiers Get Rid of Dust Completely?

No. While air purifiers might be able to get rid of the great majority of dust in the air, they can’t get rid of all the dust in the air. You will definitely notice a change in how much dust in the air you breathe, but there will still be some dust. Dust will always be present because we make dust and kick up dust just by living our lives. That’s why air purifiers need to work all day every day.

Air purifiers are great machines that can and do make the air you breathe a lot cleaner, but they’re not God. They can’t just snap their fingers and say “Let there be no more dust.” As nice as that might be, it’s not something that we’ll probably see any time soon.

What Should I Look for in an Air Purifier for Dust?

There are a lot of things that you should look for when you buy an air purifier to help with any dust problem in your home or business. The first thing you should look for is a HEPA filter, then look to see if it’s for the size of room that you’re putting it in, and then look for a pre-filter.

Look for a HEPA Filter When You’re Buying an Air Purifier to Help With Dust.

When you’re shopping for an air purifier to take care of your dust problem, you need to find an air purifier with a HEPA filter. Better yet, a True HEPA filter (which is just a better version of the HEPA filter). HEPA filters are amazing at cutting down on the amount of dust in the air around you.

You don’t have to get a True HEPA filter to take care of dust, you don’t even have to get an air purifier with a HEPA filter. These are just two kinds of filters that will give you the best possible results.

If you’re interested in a “natural” air purifier, then there are actually some air purifiers that ONLY use water as their filter. Literally just tap water. Those are super cool and they actually do a decent job at capturing dust too! You can read up on water-based air purifiers in my article here.

How Big is the Room You’re Putting the Air Purifier in? Is Your Machine Rated for That?

Something else to keep in mind is the size of the room you want to put your air purifier in. Room size is a major part of finding the best air purifier for you. While you can fudge the numbers a bit, we don’t recommend that you undercut yourself too much. That will only hurt you in the end.

How will it hurt you? Well, your air purifier might be unable to keep up and, because of that, you’ll still have dust in your air. Provided, it will likely be a whole lot less, but there still will be more dust than if you just got the right machine in the first place. Additionally, your air purifier will likely need more replacement filters/need its filters cleaned more often.

If you have to replace more filters, that little bit of money that you saved could be a wash. You could end up paying more in the long run.

Please, don’t skimp on your air purifier if you’re really worried about dust. It’s usually just a little bit more to get a few more square feet covered, provided you shop around a bit.

Look for a Pre-Filter When You’re Shopping for an Air Purifier!

Honestly, this is one of the biggest things that I think anyone should look for and I’m surprised more people don’t make a fuss about it. Pre-filters, as the name implies, are filters that air purifiers have that come before the main filter. A main filter, in most cases, will be your costlier HEPA filter.

Most pre-filters are actually washable, which means that you won’t have to buy a replacement, like you do with a lot of HEPA filters.

Ok, but what does a pre-filter do?

Pre-filters are usually fabric, but they can be metal grids as well. Both work pretty well, but I personally prefer the fabric pre-filters because I can toss most of them in a washing machine, whereas the grids mean I have to pick out all the gross dust and other things that it picked up over the course of who knows how long.

Pre-filters are used to capture larger things out of the air, things like dust bunnies, hair, and stuff like that. That’s really important because it means that those larger particles don’t clog up your main filter, which buys you a whole lot more time with that main filter!

Because your main filter is usually a costlier filter like a HEPA filter, every bit of extra time that you can get between needing a replacement can be super nice.

If you have so much dust in the air of your home that you can see it on most days, then a pre-filter is just about an absolute must. Not getting one would mean you will buy so many more filters in the long run to keep your home’s air as clean as it can be.

What Air Purifier Should I Get for My Home’s Dust?

Air Purifiers for Your Bedroom

If you’re looking for a cheap air purifier for your bedroom, then I’ve personally enjoyed the Three Musketeers mini air purifier. You can check that machine’s price on Amazon here. No, this isn’t the best air purifier out there, but it gets the job done well enough.

If you’re looking for a better air purifier for your bedroom, then the Blueair 411 is probably the best air purifier out there right now for that. It even has a pre-filter, activated carbon filter, and it can kill airborne germs! You can pick the Blue Pure 411 air purifier up on Sylvane’s store here.

Air Purifiers for Your Living Room and Kitchen

I’ve got two options for this one as well. The SilverOnyx air purifier is a pretty affordable option for most living rooms and other good-sized rooms in your home. My family and I have really enjoyed ours, but we did fudge on the numbers a bit for the size room it’s in! Regardless of that, we’ve still noticed a really big improvement in our home’s air quality. You can check to see the SilverOnyx’s air purifier’s price on Amazon here.

Blueaire Blue 211 Air Purifier

And, once again, one of the best air purifiers for larger rooms is part of Blueair’s Blue Pure series, just like the 411 I mentioned earlier. This unit’s washable pre-filter is easy to clean, and it’s super good at clearing the air of dust, allergens, odors, VOCs, and germs. You can find this air purifier on Sylvane’s store with this link.
