Where Does All That Dust in Your Home Really Come From?

Ever wondered where all that dust comes from? Here’s a clue: it’s been with you since birth… literally.

Most of the dust in your home isn’t just dirt tracked in from outside — a significant portion actually comes from your own body. Every day, humans shed millions of tiny dead skin cells, and these cells become a major component of household dust.

What Makes Up Household Dust?

Dust is a mixture of many tiny particles, including:

• Dead skin cells

• Fabric fibers from clothing, upholstery, and carpets

• Pet dander and hair

• Pollen and plant debris

• Soil and dirt tracked inside

• Dust mite waste and insect parts

• Tiny particles from paint and plastics

While dead skin cells typically account for about 10–15% of dust, they’re often the biggest single contributor.
