How to Use Air Quality Monitors for Accurate Indoor Measurements

Air quality monitors provide insight into the health of your indoor environment by measuring particles and gases that can affect comfort and wellbeing. To get meaningful data, proper use and placement of these tools are essential.

Begin by locating your monitor in a representative part of the room — away from direct airflow vents or windows. Placing the device in a central, open area helps ensure that it captures typical ambient conditions rather than localized anomalies.

Understand what the readings mean. Many monitors track particulate matter (PM2.5/PM10), volatile organic compounds (VOCs), and other indicators like CO₂ or formaldehyde levels. Familiarize yourself with what levels are considered healthy versus concerning so you can interpret trends rather than reacting to isolated spikes.

Consistent monitoring over time provides the most reliable picture of indoor air conditions. By using a quality air quality monitor correctly, you can make informed decisions about ventilation, filtration, and behavior changes that support a healthier indoor environment.
