Quick Answer: Will an Air Purifier Remove Dust or Help With Dust Mites

Air purifiers can be effective in removing dust particles and dust mites that are suspended in the air. Air purifiers with a mechanical filter and ionizers are effective against household dust. Purifiers that have a HEPA filter are the most effective type and ionizers may produce ozone while working and thus are not the best available option.

A variety of air purifiers are available in the market which uses different technologies and have varying capabilities and efficiency.

Different types of air purifiers have their own sets of advantages and disadvantages and might be effective against certain types of pollutants and ineffective against other types.

This article will look at the ability of various types of air purifiers in removing dust and dealing with dust mites.

What are Dust and Dust Mites and How they are Caused

Common household dust is a mix of sloughed-off skin cells, hair, clothing fibers, bacteria, dust mites, bits of dead bugs, soil particles, pollen, and microscopic specks of plastic.

Two-thirds of household dust comes from outside, in the form of dirt stuck in on feet, and airborne particles like pollen and soot. The rest is often carpet fluff, clothe fibres, human and pet hair, dead skin cells, etc.

Dust mites are microscopic bugs that commonly live in house dust. Dust mites eat skin cells shed by people, and thrive in warm, humid environments.

Household items such as bedding, upholstered furniture and carpeting provide an ideal environment for dust mites.

Both dust and dust mites can trigger allergic reactions in many individuals.

How Air Purifiers Can Benefit in Removing Dust and Dust Mites

Dust and dust mites can often trigger allergic reactions in people and since they are present almost everywhere, it is important to control/remove dust and dust mites from one’s sorroundings.

Thus the right air purifier for dust removal can be very helpful.

Many air purifiers in the market are designed to remove large dust particles from air.

Air purifiers with mechanical filters (especially HEPA filters) are extremely effective in removing dust particles by trapping them in filters. They are effective against dust mites in the air too.

Dust particles usually range from 2.5 and 10 micrometers in size, though some fine particles could be even smaller while dust mites usually have are between 0.2 and 0.3 millimeters in size.

Since HEPA filters remove 99.97% of particles that are greater than or equal to 0.3 microns, they are very effective against dust.

Electrostatic or ionizing air purifiers can also be helpful in removing dust particles from air by charging dust particles and making them settle down on surfaces/objects.

What kind of Air Purifiers Work Best for Dust and Dust Mites

While air purifiers are useful in removing dust and dust mites from the air, it should be kept in mind that all air purifiers are not the same. Some are much more effective at removing dust and dust mites than others, while other types of air purifiers might be ineffective against these types of pollutants.

In general, it should be kept in mind that air purifiers can only remove dust and mites that are in the air. Dust on the floor and surfaces cannot be dealt by these devices.

Thus controlling/removing potential sources of dust and dust mites are also important.

This section will take a look at various types of air purifiers and their suitability for removing dust and dust mites.

Air purifiers with mechanical filters

Purifiers with mechanical filters are very effective against dust and dust mites and those equipped with a HEPA filter is the best choice.

These filters trap dust and mites but do not dispose of/destroy them and so filters should be cleaned/replaced regularly.

Ionizer Purifiers

These can be effective in removing dust from air, but the dust settles down on objects and surfaces and may easily re-enter circulation and can make spaces dirty too.

Also, these devices produce ozone and so in short although they are effective against dust they are not the best option.

Ozone generators, Carbon filters, and UV purifiers

Ozone generators, carbon filters, and UV air purifiers are ineffective against dust and dust mites.
