Will An Air Purifier Get Rid Of Dust In My Home?

You might think sweeping behind the couch and under the carpets can rid you of household dust, but the truth is, high levels of dust remain in the air, this can cause dust allergies in certain people, and also enter peoples lungs, leading to health conditions.

Luckily, an air purifier for dust can help reduce the amount of hidden indoor dust in your home by trapping dust particles up to 0.3 microns in size before they settle on a convenient surface, this will help make the air cleaner to breathe in and lead to an overall dust reduction in the household. 

So as you can understand more about dust, where this creator of dust comes from and how an air purifier can help, we've composed an informative article below that will give you all the knowledge you need for tackling dust removal at home.

What Causes Dust In Your Home

First of all, let's take a look at what causes dust within your home. Thousands of dust particles can come from unexpected materials, not just your dead human skin cells as many would assume. 

Most of these dust particles are normal but can affect air quality and become irritating dust particles in excess. 

We have listed out some common dust sources below that can lead to the accumulation of dust in your household, most of these sources of dust are from organic material which consists of humans and animals.

  • Matter from the outside air. 
  • Dry soil stepped inside. 
  • Pet dander - Many people tend to be allergic to pet dander, rather than pet hair itself, this is due to the saliva and protein found within the skin cells dropped by your animal, which over time, can lead to dust.
  • Dust mites - House dust mites are pretty much present in any home and can cause symptoms of dust allergies when breathed in if there is a high dust mite population, the droppings of these dust mite particles are what cause dust.
  • Insects - Dead insects parts and trails can leave dust over your household.
  • Mould - Mould spores and mould, in general, are at risk for dust accumulation and don't tend to be harmful to most people, unless you are allergic to the indoor dust particles. 
  • Pollen - Even small pollen airborne particles can potentially make their way inside your household to form dust.

Is Household Dust Bad For Your Health? 

As we have mentioned above, mould, pollutants, and dust mite allergens can all be bad for your health when breathed in excessively, but how bad is dust particles for your health when they enter your lungs in general? 

Well, most dust particles that are in the air come from organic material and are nearly impossible to eliminate, even with an air purifier. Most people are used to dust particles, but for those people who already have respiratory health problems, a high percentage of dust can start to trigger asthma symptoms and dust lung issues. 

Types of smoke such as cigarette smoke can affect the type of air quality, and high exposure to dust over longer periods will become a harmful lung irritant for many, potentially leading to severe asthma attacks one day. 

Many dirt on dust has chemicals that we can breathe in too, and over time, our natural defence mechanism defending our respiratory system against dust can be weakened, making us vulnerable to getting repository illnesses more often. 

If you have allergies to dust from surfaces and the air, then you might experience some common allergy symptoms such as - 

  • Coughing. 
  • Sneezing. 
  • Watery eyes. 
  • Tightness in the chest. 
  • Itching.

Can An Air Purifier Help Me Remove Dust From My Home? 

So now we know all about dust and where it comes from, let's explore what types of purifiers for dust you need and whether they can or cannot improve the quality of air in your household by reducing dust particles floating around. 

An air purifier can help reduce dust build-up in your household as it traps the grey dirt with ease through its HEPA filter, removing not just dust from surfaces, but also the dust in the air which you cannot see. 

The trapped dust particles in our filter for dust will separate the fibres from the air, helping you rid of dust in your home which would have settled on to surfaces. 

As dust particles are so small, an air purifier that has a HEPA filter will be the best option for dust control in your home, HEPA filters can catch particles up to 0.3 microns in size which is what travels into our lungs the easiest, they are 99.97% efficient against trapping these dust particles too, and can get rid of large components of dust around too with larger particle size. 

It is important to note that an air purifier will never be able to remove dust from your home entirely until you tackle the source collector of dust, and there will always be some particles here and there, but an air purifier will help in the reduction of dust and can improve air quality dramatically for those suffering from allergies. 

We have listed several other benefits you can get from using an air purifier for dust in your home - 

  • Removal of bad odours. 
  • Get rid of harmful airborne chemicals in the air. 
  • Helps with sleep. 
  • Increase lifespan. 
  • Reduces allergy symptoms.

There are many different options of air purifiers for dust on the market, but one type of air filter alone you should avoid are filters made with a carbon filter, as these are only effective in trapping gases, not larger particles such as dust and dust mites. 

We have listed out some other specs and considerations you should be thinking about when looking for your best air purifier for dust below. 

  • The filters - Most of the time, the more filters that your air purifier comes with, the better, as this means and filter out more types of bad particles in the air. You should look for a purifier that has; a pre-filter, HEPA filter and active carbon filter, this should help you reduce dust and other chemicals in the air. 
  • Size - Make sure you measure the size of your room in your house and get an air purifier that can clean the air fives times over within an hour for effective dust removal around the home, getting too small of a purifier will likely prove ineffective and you will see/feel little difference in the quality of the air. 
  • Noise - Some air purifiers for dust can be pretty noisy, so check the dB rating of your model before you buy to make sure it's suitable to live with. You can always set the purifier to a lower setting if it is too noisy.


How many micrometres in size are dust particles? 

Most dust particles have a size of five microns or even less, which makes them very hard to trap in standard purifiers with regular filters, that's why HEPA filters are very effective against reducing dust as they can trap particles of smaller sizes. 

Is a HEPA air purifier effective against dust? 

Yes, a HEPA air filter can remove up to 99.97% of dust particles in the air, from dander to pollen and dead skin cell dust, helping improve the overall quality of air in your household. 

Can cigarette smoke cause dust in the air? 

Cigarette smoke can be found in dust particles and can contribute to dust debris found in the home, whether it is brought inside from the outdoors or smoke inside of the house.

What else can I do to reduce dust in my home? 

Some other ways you can tackle dust is by vacuuming around your home, wiping down surfaces and washing bedding, however for dust in the air you will need a purifier to help you out.

What is an organic material and how does it cause dust? 

Organic material is made up of us and refers to debris from food, skin cells, pets and more, this organic material is present in every household at moderate levels or high depending on the cleanliness. 

Final words 

To conclude, air purifiers cannot remove dust entirely from your home but can assist in the reduction of dust particles in the air, by trapping them with their HEPA filter, which stops dust from having a chance to settle on surfaces around your home. 

An air purifier can additionally help with reducing allergy symptoms related to dust around the home and keep the air fresh for members of the household.
