Professional air quality sensor for indoor & outdoor use

The invisible dangers of air quality

The air inside and outside your home is invisible. Even when it is dangerous. Breathing polluted air can lead to serious health issues, especially in children and adults with respiratory and health issues.

Know what you breathe

AirLink accurately measures particulate matter for PM1, PM2.5, and PM10 to give you easy-to-understand graphs and color-coded Air Quality Index (AQI) readings based on inhalable particles that are small enough to penetrate deep into the lungs and enter the bloodstream.

Versatile mounting options

Place AirLink on a desk or countertop, or mount on a wall inside or outside. Outdoor housing provides protection.

Global air quality indices

Choose from a growing list including US, Canada, Mexico, China, EU, UK, Australia, India, and South Korea.
