The air that we breathe every day is a mixture of several gases. In contrast, it is oxygen that our body primarily needs. But we also inhale the other constituents of air. The earth’s atmosphere is composed of 78% nitrogen and 21% oxygen, and the remaining one percent of air consists of other gases.
Moreover, many other airborne pollutants also exist in the air like dust, dust mites, pollen, allergen, etc. First, we must understand dust and dust mites before jumping to how does dust get in your house.
What is Dust?
Dust refers to fine particles of solid materials. Dust in indoor areas like home or office may contain burnt meteorite particles, plant pollen, human or pets skin cells, fibers, animal fur, decomposing insects, human or animal hairs, and outdoor soil.
All these tiny particles float in the air for a long time until they lay down on the walls, carpets, or furniture’s and when found in the musty atmosphere, they start breeding dust mites.
You can see this microparticle in a sunlight beam entered the room through the window, how freely they float in the air. However these airborne pollutants can be captured easily through the HEPA (High Efficiency Particulate Air)air filters .
What is Dust Mites?
Dust mites are the byproduct of dust in indoor areas. Dust mites flourish in a dark, warm, and moist atmosphere and are mostly found under carpets, soft furnishers, and beddings. They eat human or pet’s dead skin cells and trigger allergic reactions.
How Does Dust Get in Your House?
Dust is formed from different indoor and outdoor sources, but humans living in the home are a major source of indoor dust particles. The human body replaces its body cells every day. A lot of dead skin cells dispose of in bedding, upholstered furniture, and other living areas.
Human hairs are broken down continuously; after some time, these hairs turned into small particles and became part of dust. These dead skin cells and hairs are very lightweight; they float easily in the air and settle down indoors.
Any floating particle in the air that is larger than 0.3 microns can be captured through the air purifier. So, using a quality air cleaner in your home is necessary to reduce dust in indoor atmosphere like office and home.
The main source of indoor dust is outdoor sources. Some scientists in Arizona did some studies and what they found was that about 60% of household dust comes from outside. So, everything that you open your windows or your doors, or your air ducts, that dust comes inside.
Pollen, soil, mold spores, soot, and other fine particles from outside air are entered through the window, crakes, vents, and air ducts. When we come from outside, these microparticles also entered our home through our clothes and luggage.
Not only yourself but your different activities also contribute to dust, like your clothes made of fiber, and when the fiber is shed, it turned into dust. Fabric softeners, soft furniture, carpets, towels, and even food are a source of dust in your home.
Like humans, the pet is another source of dust. Their dead skin cell, hairs, and dried saliva mix into dust. Pets also bring fine particles like mold spores and pollen from outside. Fine particles from pets are traveled far away through our clothes.
On the other hand, birds also release dust and dander while fluttering. These birds responsible to produce airborne dust with their feathers in the indoor areas.
Heating and Air Systems
Home air and heating system is also responsible for getting dust in your house. Due to poor ventilation, dust comes into your home or office. If you haven’t changed or cleaned your AC filters, they could spread dust in indoor areas.
Furthermore, leaking air ducts are also sources of dust. These leaked air ducts allow the dust to come in from the outside environment.

Our busy lives have resulted in our minds being simultaneously occupied by many things; however, our body doesn’t fail to carry out the vital processes. We need to survive without us even realizing it; our body carries out important functions continuously.
One such process is breathing; we breathe while we’re awake working. Even while we sleep, we are breathing. The main source of this pollution is dust and dust mites.
Dust is found everywhere; no one can hide from exposure to dust. A small amount of dust exposure can be handled through our body self-defense system. Still, when its concentration level increases, the best air purifier becomes essential to use to make your house dust free.
The size of dust particles is also mattered according to their health effects. Dust particles inhaled through respiration and traveled to the lungs, while some small particles under 2.5 micron entered the bloodstream. Some of the major side of effects of dust on human health are listed below:
- Eye, nose, and throat irritation
- Lungs infection
- Allergic rhinitis
- Wheezing, coughing
- Shortness of breath
- Heart diseases
