The 8 Best Air Quality Monitors of 2020

Have you tested the radon levels in your home lately? Radon is a naturally occurring radioactive gas found in virtually all homes, and it can be potentially toxic at high levels. The Airthings Wave Plus is the first-ever air quality monitoring system is able to detect radon. But that’s not all—the smart monitor also checks carbon dioxide (CO2) levels, total volatile organic compounds (TVOCs), temperature, humidity, and air pressure.

This battery-operated device holds a charge for up to 16 months and can be installed anywhere in your home. It connects via Bluetooth and syncs to the free Airthings Wave app to give you a comprehensive readout and total control over your home’s air quality. The monitor itself has color-coded indicators that tell you the status of your indoor air. It’s also compatible with Alexa, Google Assistant, and IFTTT smart home devices. Once the indoor air quality monitor is installed and set up, a week-long radon calibration period will begin—which is about how long it takes to get an accurate radon reading.

For a more affordable option that gets the job done, consider the Air Quality Monitor from EG Air. This reliable monitoring device accurately measures TVOCs and formaldehyde concentration (CH2O), as well as super-fine dust particles measuring under 2.5 microns in size. When this microscopic dust matter enters the lungs, it can aggravate asthma and make people more prone to illness. 

A standout feature of the EG Air Air Quality Monitor is its built-in fan, which continuously measures ambient air for real-time readouts. This portable indoor monitor can be set up and moved around to any area of your house, and it’s also ideal for on-the-go testing in cars, hotel rooms, and rental homes. It runs on a rechargeable lithium 2200mAh battery or a DC 5V power cord. Readouts are displayed on the device’s easy-to-read LCD screen.

Airborne dust and mold particles can aggravate allergies, cause asthma flare-ups, lead to headaches, and result in several other negative health side effects. With the cutting-edge uHoo Indoor Air Sensor, you don’t have to wonder about the invisible pollutants lurking in your home.

It checks your carbon dioxide levels, nitrogen dioxide (NO2), carbon monoxide (CO), TVOCs, PM2.5, temperature, humidity, ozone, and air pressure.

The Indoor Air Sensor from uHoo has a sleek design and it’s surprisingly compact—not much bigger than a standard coffee mug. This high-tech gadget is powered by a multi-core processor and encrypted with 128-bit SSL. You can sync it with your smart home hub and pair it with an air purifier or thermostat for automatic air quality control. The uHoo app is easy to use and offers personalized alerts, tips, and room-to-room insights about the air in your home.
