How to Pick the Right Air Quality Monitor
Choosing an air quality monitor depends on what you want to measure and where you plan to use it. Here's a breakdown to help guide your decision:
1. Decide What You Want to Measure
- CO₂ – Indicates ventilation levels indoors.
- PM2.5 – Measures fine particles like smoke and dust.
- TVOCs – Tracks volatile organic compounds from cleaning supplies or furniture.
- Temperature/Humidity – Helps with general comfort and mold prevention.
2. Choose Between Indoor or Outdoor Use
Indoor models are more common, but if you need outdoor readings (e.g. wildfire smoke), look for weatherproof options like PurpleAir.
3. Look for Key Features
- Display type – Some have screens, others app-only.
- Smart integrations – Check for Alexa, Home Assistant, or Apple Home support.
- Battery vs. plug-in – Portable units are great for spot checking.
