Breathe Airmonitor Plus Review: An 8-in-1 Smart Air Monitor That Tracks More Than Most

Breathe Airmonitor Plus, an 8-in-1 home air-quality monitor, was tested during Canadian wildfire smoke and fall allergy season to evaluate household pollutant tracking. The Breathe Airmonitor Plus tracks PM2.5 and PM10, measures CO2 with an NDIR sensor, and monitors TVOCs and formaldehyde. It supplies audible alerts and app-based Wi‑Fi visibility but does not detect carbon monoxide. Optical particle counting and a compact, 3.3 x 2.8 x 1.7-inch design support room-to-room use on a 1,600mAh battery. Placement guidance recommends breathing height, away from vents, windows, sunlight, and purifiers for accuracy. The app keeps up to 90 days of cloud data with CSV export over 2.4GHz Wi‑Fi. Pricing runs about $100–$130, with a two-year warranty and 30‑day returns; it monitors air but does not clean it.
