The Science of Household Dust
Household dust isn't just skin cells and lint. In fact, it is a complex reservoir of chemicals that have shed from furniture, electronics, and even the shoes we wear inside.
What's Hiding in Your Dust?
- Flame Retardants (PBDEs): Used in older foam furniture and electronics.
- Phthalates: Shed from PVC flooring and plastic toys.
- Heavy Metals: Lead and arsenic tracked in from outside soil.
To reduce your exposure, use a vacuum with a HEPA filter and damp-mop hard surfaces regularly. Removing shoes at the door can reduce lead levels in dust by up to 60%.
