Let’s start today’s topic where does dust come from? As soon as the sun rises, dust builds up in homes. It gets on our things and messes up the carpets. Sloughed-off skin cells, hair, and clothing fiber are just some of what makeup house dust. There are also dead bugs and soil particles in the dust and microscopic plastic particles. It’s our trash, and, as it turns out, it can tell us a lot about how we live.

For one thing, dust isn’t very stable. Those hairs and old skin cells that fall out can pick up a wide range of contaminants from the things we buy for our homes. Other pollutants can be brought inside the soles of our shoes. We can bring them inside with us. This is why dust can be full of things like persistent organic pollutants, metals, endocrine disruptors, and hair that’s fluffy and dirt from the garden.

What is dust made of?

Dust in your home is made up of many different types of particles, like dirt that has been brought in, your skin cells, and tiny particles that have been thrown away from your carpet. People living in certain places may see coal dust or dust from a desert. Arizona is known for having a lot of this kind of thing happen. In the same way, dust from Africa can spread through the air and reach North America and Europe.

It is thought that most dust is made up of human skin among people. It’s not true, says science writer Luis Villazon of Science Focus. Skin cells fall off. Most of them are washed away in the bath or the bathroom, not spread around the house.

Most of the time, dust in your home comes from outside sources, like dirt. Dirt and other small particles are on the bottom of your shoes and your clothes and skin when you walk into the house. Afterward, these particles are spread around the house, becoming household dust. A lot of dust will also be made up of fibers from carpets that get into the air and land on different surfaces.

If you have pets in your home, you’re likely to have pet dander, a type of dust that can cause allergies.

Dust is made up of almost everything. It’s even been found that dust may be full of chemicals, like DDT (an insecticide that hasn’t been used in decades) and pesticides. If these chemicals are ingested, they could cause major health issues for people of all ages.

Dust doesn’t only live in your house. Dust is a big contributor to particulate matter, tiny solid particles that float in the air. Particulate matter is a big source of pollution in the air outside. It is made up of many different things, like ammonia, sulfate, black carbon, and mineral dust.

Where does a house’s dust come from?

The amount of dust in a house varies greatly from one house to the next. It’s usually dirt, skin cells, or clothing fibers, but it may be anything that dries and flakes off. Dust is generated by books, carpets, rugs, fireplaces, upholstered furniture, and dogs. Outside dust can be brought in by dirt, pollen, smoke, exhaust, sand, and various other factors. Mold, germs, and dust mites, for example, are all known to live in and flourish in the dust. “Dust is a mixture of all sorts of stuff,” says Paloma Beamer, an environmental policy professor at the University of Arizona, in a Time article. Making a list of all the potential objects would be impossible.”

Fighting dust may seem like an endless war, but it is one worth fighting. Essentially, a mixture of indoor and outdoor particles that hovers in the air and settles on surfaces.

The specific dust mix in any household varies according to climate, the maturity level of the house, and the number of individuals who live in it — not to mention the occupants’ cleaning, cooking, and smoking habits,” according to Beamer’s research, and “the majority of household dust — about 60% — comes from outside, through window panes, doors, vents, and, importantly, on the soles of your shoes.” Even though her study is nearly a decade old, no recent investigations have found many flaws in her conclusions.

This means that it’s not simply the presence of dust in our houses that matters, but the type of dust. Let’s look at some of the most regular dust components:

Insects and insect droppings

Insect body pieces and feces, particularly from cockroaches, are frequently found in dust. This could increase allergy reactions if you’re allergic to cockroaches. Cockroaches don’t discriminate when it comes to which homes they infest. Even if your home is clean, bugs can enter from the exterior, the neighbor’s house (especially if you live in apartments), or through the plumbing.

Food Debris

It’s easy to spill some crumbs when you eat in front of the TV. If you clean up the food waste right away, you won’t have much problem. Small food particles often fall and get lost, making them part of the dust.

Dead skin

A widespread misunderstanding holds that most dust is composed of dead skin cells. Even though dust can and frequently does contain dead skin, people overestimate the amount of dead skin in the dust. Instead, dust mites and other airborne contaminants are drawn to the dead skin that floats around in your house.

Pet Dander

Another typical allergy found in the dust is pet dander, the small particles of skin that animals shed. Even if you don’t own a pet, visitors to your home may be carrying pet dander on their clothes. Pet dander draws dust and dust mites as it circulates through the air and settles, aggravating the present issue.

Dust Mites

There are naturally occurring microscopic pests known as dust mites, which flourish in humid conditions. Even if your home isn’t overly hot or wet, dust mites are likely to be lurking in your beds, carpets, and curtains. Pet dander and dead skin are favorite food items of dust mites; thus, the more dust you have, the more dust mites you’re likely to have.

Pollen, soil, and particulate matter

Sixty percent of the dust in the average home comes from outside, as previously stated. Because pollen is a well-known allergy, your shoes, clothes, and hair can bring it into your home. When you walk around your house, you disperse pollen, which floats through the air and lands on various surfaces. Soil, particulate particles from smoking, and any other outside contaminants you can think of are all examples.

How to take action against dust?

Life is full of dust. Although the air inside your house is kept at a constant temperature, it will seep into your home through the cracks around your windows or ceiling cornices and attic spaces. In the end, all airborne dirt, smoke, fibers, and crushed materials fall like dust.

However, you have a lot of options.

We can make an effort to keep the interior dust-free. Indoors, use doormats, and remove your shoes. There is a doormat for mud-splattered youngsters and pets and a changing area for dirty work clothes.

What chemicals we allow into our houses and how they are used can be controlled by us. Plastic, insecticides, and water proofers contribute to a greater chemical load if used less. Don’t buy any more antibacterial products than you have to. A damp cloth with detergent or soap is effective in cleaning a surface.

Vacuuming regularly is a huge assistance. For allergy-causing dust, vacuum cleaners equipped with a fine particle filter (such as a HEPA filter) are more effective. Use a damp cloth instead of a dry cloth or feather duster to remove dust from surfaces. As a bonus, wet mopping also eliminates fine dust left behind by sweeping or vacuuming.

Conclusion:

Many things make dust, like dead skin that people and pets shed (yuck!), fibers in carpet, bedding, garments, upholstery, and dust from the outside. Study after study has shown that about 60% of the dust in our homes comes from outside. If you don’t want to get rid of all of your carpeting or leather furniture, get rid of the curtains, or make Fido sleep outside, your preferred option at reduce dust.
