I’m looking to buy an AQI monitor to track both indoor and outdoor air quality, but I’m not sure which features are most important. How accurate are consumer-grade AQI monitors compared to official monitoring stations, and are there specific brands or sensors that work best for allergies or asthma? Also, is it better to go for a smart AQI monitor with app support or stick to a standalone device? Any advice from people who use them regularly would be really helpful.
