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

In fact, indoor air quality can be up to 5X worse than outdoor air quality.




The air we breathe can contain pollutants called Particulate Matter (PM), measured in microns. A human hair measures around 70 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. Particles under PM 10 can get deep into your lungs, and some may even get into your bloodstream. And 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 – like allergens and pollen.


Potentially harmful, particles and gases can be found throughout the home, these include…


PM 10

Pollen and allergens from plants and flowers

PM 5.0

Bacteria and mould spores

PM 2.5
