Indoor Air Quality Monitor for Allergies and Asthma

Indoor Air Quality (IAQ) monitors have come a long way in the past few years. Air pollution sensors used to cost several hundred dollars and was used only by researchers, but as with any technology, such sensors have become cheaper and smaller which have led to a whole slew of compact monitors geared towards consumers who can purchase to monitor their own home air quality. Keep in mind, many portable air filter units now have such sensors built-in.

These monitors have become useful for patients with severe allergies and asthma who can now monitor indoor air quality along with weather checks and outdoor pollen levels. Most devices can connect to WiFi and have an app where you can see the results in real-time and over time.

Depending on the device, built in sensors can measure:

• PM2.5: very small dust particles
• PM10: larger particles like pollen
• VOCs (Volatile Organic Compounds): chemical pollutants like cleaners, gasoline, and paint
• Temperature and Humidity: promotes the development of mold and mildew
• Carbon Monoxide (CO): produced by any appliance in your home that burns fuel
• Carbon Dioxide (CO2): released by your home’s heating system

Do your homework regarding what the device will measure before purchasing as not all devices will detect all these things!

So here are a few IAQ monitors one can purchase on Amazon that range in price from under $100 to several hundred dollars:
