Dead human skin cells. Dust mites and their faeces. Pollen, pet dander, mould and bacteria. Lurking inside house dust is a cocktail of these unpleasant, microscopic particles. They’re called allergens, and just 0.000001g can be enough to trigger the coughing, sneezing and itching of an allergic reaction.
Some allergens are just 0.00005 microns in size. That's 0.0005 centimetres. Or 200 times smaller than a human hair. This means they can easily enter the body through inhalation. When this happens, some people's immune systems overreact to the presence of the particles, producing antibodies to repel them. Subsequent physical reactions include itching eyes, a running nose, sneezing and coughing to combat the allergens.
Your home may look clean, but microscopic dust remains hidden in floor crevices or ground into carpet, rugs and soft furnishings. Within this dust are allergens, and inhaling even a small amount is enough to trigger an allergic reaction. A single gram of house dust can contain around 100,000 mould spores alone.
Removing the hidden dust can help reduce the number of allergens left in your home. Regular vacuuming is an effective way to keep house dust under control.Click the arrow to see how to reduce allergens in your home.
Reduce their food supply – vacuum wood floors, mats and carpets to reduce the amount of skin cells and other organic matter.Target areas where you sit and sleep – vacuum mattresses and sofas to suck up skin cells and dust mite faeces.Stop them breeding – air out your mattress to cool the temperature of the bed. This prevents dust mites from breeding as quickly.
Regularly vacuum floor surfaces – most pollen is actually found on the floor of your home and under furniture, not in the air.Don’t let pollen in – outdoor clothing (like your coat) can bring pollen into the home, so keep it clean. And make sure windows and doors are closed during high pollen seasons.
Avoid a build up of allergens – your pet sheds every day, but vacuuming regularly ensures the hair and dander is trapped before it builds up.Keep pets away from your bedroom – reducing how much pets are around areas where you spend a lot of time can reduce your contact with allergens.
The presence of mould spores is heightened during wet weather and harvesting seasons.The spores are present in house dust as well as air borne.Remove house dust and tackle damp areas on walls, ensuring they are free from mould.
Other vacuums can suck up dust and allergens from your floors and upholstery. But if they don’t have an efficient filtration system, they can disperse those allergens into the air you breathe – making it much easier to inhale them. Click the arrow the find out more.
A filter can be made using HEPA material, but if it’s not designed to cope with a vacuum’s airflow, allergens and bacteria can pass straight through and out into the room.Click the arrow to find out more.
A filter can meet HEPA standards, but if it’s not properly sealed, dirty air can bypass the filter, dispersing dust and allergens into the home.Click the arrow to find out more.
Poor seals throughout the machine result in dirty air leaking straight back out into the room.
