Can Dust Be Good For You?

Are there any benefits to dust in your home?  Most of us would instantly say “No!”  But Wendy Leung makes a good argument for the opposite – read her article from The Globe and Mail  – This article was published more than 9 years ago. Some information in it may no longer be current.

Can Dust Be Good For You?

“Bad news, neat freaks. All that work you’ve done to keep your homes dust-free may be counter-productive.

A new study has found that household dust actually purifies the air by neutralizing harmful ozone, according to The Canadian Press.

The gross part is it’s the flakes of human skin in dust that gives it its ozone-fighting power.

Researchers from the American Chemical Society found that dust containing high amounts of squalene, a component in human skin, can reduce up to 15 per cent of ozone in the air. (Ozone, when present in the air we breathe instead of high up in the atmosphere, is a pollutant that can damage our lungs, The Canadian Press explains.)

“Dust is parts of…people that have been in that room,” researcher Charles Weschler told The Canadian Press. “I mean, that’s a gross way of thinking about it.”

Squalene is present in the oils of our skin, which makes humans “remarkably good ozone sinks,” Dr. Weschler said.

Humans shed up to 500 million skin cells per day, so just think of all the ozone-neutralizing bits of your body that are scattered around your home.

The Canadian Press warns you may not want to retire your feather duster just yet, though.

Sure, it may clear up some of the ozone in the air, but the dust itself can leave allergy-sufferers wheezing.”
