Integration simplifies your workflow by connecting air data to active solutions for a healthier environment.

Battery Life and Power

Consider whether you need a battery-powered portable unit or a plug-in model. Battery life varies from hours to days, affecting where you can place the device.

How to Use and Care for Your Indoor Air Quality Monitor

Place your monitor in a central location away from direct sunlight, vents, or humidity sources for accurate readings. Ensure it is elevated on a table or shelf rather than directly on the floor.
