Do Air Purifiers Get Rid of Dust Mites?

Updated: Apr 23, 2020


There are all kinds of mites: itch mites, clover mites, chigger mites, scabies mites, rodent and bird mites, and so on. In fact, there are close to 48,000 known mite species worldwide, and some entomologists estimate that there are many more.


Learn more about the types of mites.


In this article, we are focusing ONLY on dust mites, perhaps the most ubiquitous of all these species, and certainly the one most people have in mind when they talk about these tiny ‘invaders.’

Mites Are Everywhere! (You Just Can’t See Them.)


Actually, calling them ‘invaders’ creates entirely the wrong impression. They’ve always been with us. The main reason being that these microscopic organisms depend on the dead skin of humans, and animals for sustenance. Practically anywhere you find humans and/or animals you’ll find dust mites. Relatives of the spider, mites thrive in warm, humid climates, but they can be found all over the world.


You will usually find them in bedding, upholstered furniture, carpets and rugs, baby cribs, curtains and drapes, but they’re really everywhere! That is, if you can even find them in the first place: they’re minute in size ̶ 0.25 to 0.3 millimeters long ̶ which makes them virtually invisible to the naked eye. Sweep a floor, walk on a rug or carpet, make the beds, dust bookshelves, any of those actions and you’re likely to send your resident dust mites airborne.



Are Dust Mites Dangerous?


When those dust mites soar into the air, so do their feces which, it turns out, are covered in proteins which, if inhaled by humans, can cause develop serious allergic reactions. Add to this the unfortunate fact that mites can produce up to 200 times their own weight in faeces, and it’s easy to see why as many as 20 million Americans develop dust mite-related allergies every year.


And the symptoms are numerous and wide ranging, including:


  • Itchy, watery or red eyes

  • Sneezing and general nasal congestion
