Indoor Air Pollutants


Pollen can be a problem for people suffering from indoor allergies.

Smoke Particles

Secondhand smoke is a mixture of particles and gases that contain over 250 harmful compounds.

Airborne Chemicals

Cleaning products can easily evaporate into the air, creating an unhealthy indoor environment.

Dust Mites

About 20 million Americans have dust mite allergies.

Pet Dander

People can be allergic to the protein found in pet dander, skin flakes, saliva, and urine.

Viruses & Bacteria

Indoor air can make it easy for airborne organisms, like viruses and bacteria, to spread from person to person.

Mold Spores

Mold spores live in moisture-rich or damp environments, such as basements, bathrooms, and kitchens.

Cooking Odors

It is difficult to get rid of unwanted cooking odors, such as fish and garlic odors.
