6 Best Air Quality Monitors 2021 – Buyers’ Guide & Review

Do you feel suffocated or is it hard to breathe inside your home? Maybe it’s high time you consider buying an air quality monitor.

Air quality monitors usually come with 3-4 inbuilt meters that monitor different gases, generally including oxygen, carbon monoxide, carbon dioxide, and other harmful volatile gases.

The monitors don’t help filter the air, but it’s still great to have a device alerting you about the air quality.

Buyer’s Guide: Best Air Quality Monitor

Multiple Sensors

Any decent air quality monitor should have at least 3-4 filters and measure the common air-related factors, which usually include formaldehyde concentration, VOCs, and PM2.5/PM10. Having multiple sensors makes sure that no harmful element in the air gets left behind while monitoring the house’s pollution level. Many high-end air quality monitors have 5-6 sensors measuring the temperature and humidity level as well.

Make sure to choose the right monitor according to your needs.

Alert Indicator

As air quality monitors don’t help much in filtering the air, their only purpose is to alert you whenever any air factors go beyond a safe threshold. All air quality monitors have a different approach in alerting their users. Some air quality monitors have color-coded indicators to alert you at varying levels of danger. In contrast, some have a single alarm to alert you when the cumulative air quality level goes beyond safe limits.

Wifi/Bluetooth

Wifi or Bluetooth connections are not very common in air quality monitors. Still, you will likely find it in the high-end monitors with their apps to give you more detailed data of all the air quality parameters. If you need easy accessibility or more comprehensive data, you should consider spending some extra bucks on an air quality monitor with Bluetooth or wifi.

Battery Life

As air quality monitors work continuously to measure all the air parameters, they need to have adequate battery life. An air quality monitor should at least have a battery with a 2000 mAh capacity.
