When Shawn Ellis tests the air in parts of a house where cleaners are stored, he is measuring volatile organic compounds (VOCs). His meter won't tell you how strong or harmful the chemical particles might be. It will provide clues as to how many particles there are.

'Can always smell the cleaning products'

"You can always smell those cleaners even though they’re all tightly sealed."

Everywhere the cleaning products are kept, the readings jump. The average home normally reads about 50 parts per billion.

We asked Ellis to test three products that are often advertised on television: Pledge, Clorox Wipes and Lysol Disinfecting Spray.
