Indoor pollution

Pollutants can build up inside your home. But you can't always see them.

In fact, indoor air quality can be up to 7X worse than outdoor air quality.¹

Close-up of allergens in family home

The air we breathe can contain pollutants called Particulate Matter (PM), measured in microns. A human hair measures around 100 microns. Inhalable particles under 10 microns in diameter, such as pollen, are known as PM 10, while cooking gases and other pollutants can be PM 2.5 or less.

Because our houses tend to be more sealed these days, pollutants and allergens can't always escape. But they can be captured.

It's not just visible pollutants that can be harmful.

It's also those you can't see.
