What Is Dust and Why Is It Such a Problem?

While dust may appear to the human eye as little balls of fluff or gray specks, it’s made up of a bit more than that. Dust can be made up of three different kinds: organic, inorganic and biological. 

While organic dust generally consists of chemicals that contain carbon and inorganic dust may include pollutants from fossil fuel power plants, you’re most likely to find biological dust in your bedroom.

Biological dust is made up of

👉 Dead skin cells
💇 Hair
🔬 Microscopic dust mites and their body parts
🐜 Other insect bodies and waste
🌺 Pollen
🤧 Viruses
🦠 Microbes and microplastics

However, all of this stuff is naturally occurring (if unwanted) — especially dead skin cells. We shed these all the time and their collection partially contributes to the dust in your bedroom.

While you’re less likely to have organic and inorganic dust in your home, it can enter through your open windows or cracks around doors and be attracted to your clothes and shoes, which are then tracked into your environment.

While it’s impossible to rid your environment of dust completely, several health issues are associated with dust accumulation. 

These include

  • Asthma and issues with your respiratory system
  • Allergies
  • Lead poisoning.

As you can see, it’s no joke! Especially for those with asthma, allergies, or respiratory issues, dust in your bedroom exacerbates any underlying conditions and can harm your health in the long run.

Why Your Bedroom Is So Dusty (And How to Fix It)

So now that you know what dust is, what’s causing it, and what can you do about it? Here are a few ideas.

1. The fabrics in your room are creating dust

Did you know that dust can be created by the furnishings in your room, including your bedding? This is because the fibers pill and accumulate, then are released into the air.

🛠️ How to fix it: Ensure you’re washing your bedding regularly and vacuuming any rugs and carpets (ideally with a vacuum fitted with a HEPA filter).

2. Your pets contribute to dust in your bedroom

Do you have a cat or dog that likes to snuggle down with you at night? Their dander and hair are also significant contributors to dusty bedrooms — anyone with a pet will know firsthand how much they can shed.

🛠️ How to fix it: Ideally, don’t let your pets sleep in the bedroom with you. 

If you can’t be parted, just be aware that you’ll need to clean your sheets and vacuum a lot more often. Regularly grooming pets will also help lessen hair and dander shed around your home.

3. Your air conditioning unit might not be ventilating properly

Air conditioning units are great as long as they’re correctly maintained. When they’re not, not only will they be unable to work as effectively (and cost you more money), but they’ll also be unable to filter the air in your room correctly, contributing to more dust.

🛠️ How to fix it: Make sure you clean or change your air filter, and schedule this for regular maintenance.

4. The humidity in your room is too high

If the humidity in your room is too high, dust will tend to accumulate on damp surfaces.

🛠️ How to fix it: Invest in a dehumidifier and make sure it’s set to somewhere between 40%–50%

This will help reduce the dust that can settle in your room.

5. Outside contaminants are coming into your room

Opening your windows during the day is excellent for ventilation but less so for dust contaminants that may come in from the outside. You may also find that you’re tracking it in on your shoes.

🛠️ How to fix it: Keep your windows closed during the day (especially in a bustling area). Ensure you don’t wear outside shoes in your bedroom, as they could track dust in.

5 More Ways to Make Your Room Less Dusty

1. Make sure you dust properly

Most dusters just spread dust around, meaning that you’re just moving it from one place to another rather than removing it. 

🛠️ Instead, use a microfiber cloth to wipe away the dust rather than the traditional duster. Microfibers are excellent at collecting dust and can be used wet or dry. We recommend using them damp to pick up the maximum amount of dust.

2. Clean your appliances regularly

Appliances attract dust to them, thanks to the static charge they give off. This can then result in dust being spread around your environment.

🛠️ To avoid this, ensure you’re cleaning your appliances’ surfaces regularly. This could include things like air conditioning units, fans and extraction fans.

3. Install a dust screen

Dust screens are screens with very fine mesh nets that can be installed in your windows. This helps to prevent dust from outside from getting into your room. 

While installation may block your windows, it will greatly help reduce the outside dust in your environment. They’re usually easily detachable, too, so you can wash them as and when necessary.

4. Remove books from your room

Did you know that paper products, such as books, can also generate microparticles? While reading a book in bed may be a much-loved habit, you could also contribute to the dust in your room.

🛠️ Instead, keep large amounts of paper products and books out of your room and place them elsewhere in your house. Why not look into a separate reading nook? That way, you’ll keep the dust out of your bed and indulge in a unique spot just for reading.

5. Invest in an air purifier

Air purifiers, especially ones fitted with HEPA and carbon filters, are excellent at removing ultrafine particulate matter from your environment. 

This includes dust. They have a series of filters designed to remove dust particles and more from your environment. If dust is a problem in your bedroom, an air purifier will go a long way to helping deal with and remove it.
