How to choose the best air quality monitor for you?

Air quality monitors break down into two main types. We’ll mostly be looking at indoor models designed to sit within one room and provide continuous monitoring of the air quality within that space, but there are also portable devices designed for indoor and outdoor use. They’re often used by professionals or those with respiratory conditions to provide a quick assessment of air conditions wherever they are.

Beyond that, the main distinctions come down to the style and size of the monitor, any displays or connectivity, the software it hooks up to and what pollutants and conditions it detects. This last point is particularly important, as while most air quality monitors track levels of fine particulate matter under 2.5 microns (or PM2.5) and/or VOCs, some go much further to monitor temperature, humidity, finer particles (down to 1 micron, or PM1), radon gas, mould and carbon dioxide.

The more pollutants detected, the higher the cost, but that’s a price that may be worth paying if you live in an area with high radon levels or specific environmental concerns. That goes double if you or a member of your household suffers from a condition that might be triggered or aggravated by certain pollutants.
