Dust mites watch scary. Therefore you can ask, “Are your air purifiers for dust mites? deserve to air purifiers kill dust mites?”


Apparently these creatures are most likely in mine home, due to the fact that they’re in many people’s homes. A survey discovered dust mites in 84% of us beds and also 68% of europe beds.

You are watching: Size of dust mites in microns

Yet it’s tough to understand for certain whether castle in our residences or not since they’re greatly too tiny to see through our eyes. The more I write, the an ext OCD i’m becoming. Can an purifier because that dust mites pertained to our rescue?


Will waiting Purifiers kill Dust Mites?

I need to say I’m no an professional in air pollution. I’m just a devoted data nerd who was act psychology research in Beijing and then obtained (kind of) compelled into structure DIY waiting purifiers come fight the crippling air pollution I was breathing.



Most waiting purifiers usage HEPA filters, for this reason let’s begin there.

These fiber filters record over 99% of corpuscle 0.3 microns and also above. That’s great news because that my probably-dust-mite-infested home since dust mites room 200 come 300 microns long.


That’s conveniently in the variety that HEPAs capture. Now, i’m not certain if acquiring stuck in a filter would kill a dust mite. They dice in settings with low humidity, and also getting constantly swollen by wait might execute the job, but that’s speculation.

Bottom line: Most wait purifiers will catch dust mites, but may no kill them.

Wait, Dust Mites have to Be in The Air

Hang on, dust mites should be in the air for an air purifier to capture them. The problem is castle live in carpet, bedding, and upholstered furniture, for this reason they’re not generally floating in the air.

It transforms out dust mites do gain thrown right into the air. When we go on carpeting, sweep the floor, dust our homes, and adjust our bed sheets, dust mites get thrown right into the air. And because they’re so small, they continue to be suspended in the air because that 20 minutes to 2 hours.

That means purifiers can capture dust mites if you have the purifier on when dusting, transforming sheets, or even walking around. If you’re shot to target dust mites, you might want come scuff her feet along the floor.

Dust Mites produce Even smaller sized Allergens

But the picture gets more complicated for people with allergies. Dust mites produce allergens through ejecting poop particles and also “partially digested enzyme-covered dust particles.” In other words, your waste is smaller than your bodies.

These particles space as small as 1 micron or also 0.1 microns.

We’re in trouble now, since HEPA filters capture particles 0.3 and also above (according come websites prefer this one).

Fortunately for us air-breathers, this is a common misconception. This misconception would certainly lead world to conclude the HEPA filters and air purfiiers DON’T capture dust mites.

You’ll check out purifier service providers use this myth to try to justify once you need their “proprietary technology” instead, favor Molekule does.

A glance in ~ the Wikipedia web page for HEPA filter (or the data i share in this answer) reveals the HEPA filters capture lots the particles below 0.3 microns.

Heck, also pollution masks favor this one ns wearing capture tiny 0.007 micron particles (1).

Bottom line: Air purifiers with HEPA filter will capture dust mites and the smaller dust mite allergen particles they create.
