Short answer
Small room size and dirty air filter is the cause of dusty bedroom.


Why Is My Bedroom So Dusty?

It is because dust has a higher density in a bedroom than in any other place. This is because the bedroom is smaller than other rooms yet you have tons of stuff left open. Hair, clothes/ bedding fiber, dust mites, pet dander, and microorganisms are some of the common bedroom dust contributors. These airborne particles will often fall on the wardrobe cabinet, bedside table, underneath bed, and makeup table. Another common reason is the central ventilation system or air conditioner filter is clogged. When you operate for long hours, the dirty filter will end up spreading more dust in a room instead of clearing it.

Even with all the hard work cleaning and you still feel your master bedroom is dustier than the rest of the house. Look out for these 3 culprits.

  • Bedding and paper fiber – From clothes, towel to magazine and children book, all these items consist of microscopic fiber. The fiber materials will break down in due time. The dormant fiber will then become airborne when you make your bed or simply sleeping on it.
  • Skin flakes and hair – This is the big one that is leading the dust contaminants. No matter how hygienic a person is, there will be millions of dead skin cells and hair follicles dropped every day. Since we spend 1/3 of our time in bed, The excessive particles will begin building up in our bed or floor and become airborne when disturbed.
  • Other biological contaminants – Occasionally we will bring in uninvited guests into our bedroom. Those guests include pet dander, dead insect, mold, mildew, pollen, bacteria, and viruses. The biological contaminants will tag along on our shoes, clothes or backpack when we remove them in the room.

How Can I Make My Room Less Dusty?

Dusty bedrooms can be a big annoyance for many people. If your walk-in wardrobe is covered with an inch of dust even if you just did the cleaning or ceiling fan blades get dust up quickly despite rarely turn it on? We have the ultimate dust removal solution for you.

  • Change your bedding at least once a weekDust mites thrive in warm and humid temperatures which is usually the case for an indoor environment. The microbes will dwell in bed sheets, pillows, and mattresses and continue to grow if is untouched. Changing and washing your bedding will ensure all existing dust mites will be wiped out.
  • Tuck everything inside the closet – Garments, clothes, and towels all shed lots of fiber over time. Anything that is unused should be stored in the closet, drawer, container or closed wardrobe.
  • Get a HEPA air purifier – The only device that will make airborne dust magically disappear! If you have severe allergies from dust, mold, pollen, pet dander and germs, an air cleaner will do wonders. But make sure the dust air purifier is equipped with a True HEPA filter that traps particles as small as 0.3 microns. You will need that to capture all the dust contaminants.
  • Vacuum thoroughly from top to bottom – Vacuum every couple of days if you feel your bedroom is stuffed with dust. Do it from top to bottom particularly on top shelf, wardrobe or wall. If you need a good handheld HEPA vacuum like Dyson to achieve that. That way, there will be less fallen dust and it will make your next vacuuming duty a lot easier.
  • Avoid using a feather dusters – Using a duster will only transport the dust from one place to another within the same room. Instead, use a damp cloth or old rag to wipe out any settled dust.
  • Switch to the hypoallergenic cover – Costly but worth it in the long-run. From bedsheet, pillow cover to mattresses, whatever things you can opt for allergen-proof or mite-proof, go for it.
  • Avoid carpet and faux – Carpet is a dust magnet that should not be placed in a bedroom. If your sleeping spot comes with carpet flooring, you may have to vacuum more frequently or re-floor it with tiles, hardwood, vinyl, or linoleum. Make sure there are no cracks on the floor as dust and mites can creep their way in it.
  • Clean the filter – Whether is your air conditioning or HVAC system, make sure the filter is clean so fresh air can push through. That way dust that is sucked into the ventilation will be trapped by the filter for good.

Dust is a mixture of dirty particles including dust mites, pollen, dead skin cells (skin flakes), insect, fibers, and germs. Since dust consists of different microscopic bits, it will accumulate rapidly on walls, shelves, ceiling, and floor. Typically, ground dust will not cause any problem until it is disturbed and up in the air. When the dust is airborne, we are at risk of breathing or ingesting into it. This can lead to symptoms like wheezing, sneezing, chronic cough, runny nose, red eyes, and nasal congestion.
