Best Air Quality Monitor: Buying Guide

Indoor/Outdoor Usability

Air quality monitors are made to test out the concentrations of pollutants or gases in the air. Some of the models are good to check indoor, while some are meant for outdoor use. However, some of the high-optimized models can check the air quality both indoor and outdoor. The sensors used by this monitoring device make it suitable for both outdoor/indoor use. However, almost all the air-quality monitors handle it pretty well for indoor use since the pollutants are usually lesser.

LED Display

The display panel of an air pollution meter should be large enough to display all measurements at a time.  

Pollutants Detection

An air inside or outside contains various pollutants such as PM2.5, HCHO, TVOC, etc. Different low-end models do not quickly check these pollutants. This function is essential you must pick the right product that comes with all the necessary sensors and can detect all different kinds of contaminants and show the right results.

Battery Life

This function is one of the essential factors to check on before purchasing an air quality monitor. Some air quality monitors are meant to work on the direct power supply, while several portable options come with an in-built battery. Check for the model that offers the pro-longed usability.

Connectivity

Most AQM(Air Quality Monitor) devices come with support for Android and iOS devices. It is pretty helpful as you can get all the live updates right on your phone wirelessly, so there’s no need to go and check for the results on the air quality monitor itself. In fact, with dedicated applications, you can keep track of past observations and compare the details. On the other hand, some AQM devices even support Alexa and similar AI devices, which can pair the AQM with Air Purifiers.

Smart Integrations

Some of the models offer smart integration on their devices for extended usability. They provide “Google Assistant” or ”Alexa” support for easy control and use. 

Air Quality History

The device should be smart enough that it can record and store the measurements taken over time. This function will guide you if the steps you are taking to improve are working or not.

Night Light

This function is an important feature to notice before buying an air control monitor. This function helps to get the reading even at night or in dark areas.


Various Indoor Pollutants

PM(Particulate Matter)

Particulate matter or PM is the mixture of particles and droplets in the air. It varies in shape and size. These particles are measured in micrometers or microns. PM having the size of 10 micrometers or more minor can adversely affect your health as you can quickly inhale it. PM2.5 is referred to as delicate particulate matter. It has a diameter of about two and one-half microns. At the same time, PM1 is the particulate matter measuring 1 Micron.

Sufficient exposure to PM2.5 can irritate the eyes, nose, throat, and lungs, leading to allergy-like symptoms and shortness of breath. It can also aggravate the existing medical problems such as asthma and heart disease. WHO considers PM2.5 as the world’s most significant environmental health risk.

Cooking, smoking, burning fireplaces are some of the familiar sources for PM2.5.

VOCs

VOC stands for the ”Volatile Organic Compounds”. According to the Environmental Protection Agency, concentrations of many VOCs can be up to 10 times higher indoors than outdoors. Sources of VOCs include many everyday household products, including hairspray, cosmetics, cleaning fluids, disinfectants, paints, and varnishes. Burning fuels like wood and natural gas also produce VOCs.

Formaldehyde is one of the most common VOCs found in many building materials, including plywoods, glues, and insulation. It is also used in some drapes and furniture fabrics. Short-term exposure to the low levels of VOCs can cause throat irritation, nausea, fatigue, and other minor complaints. Long-term exposure to high concentrations of VOCs has been linked to more severe respiratory irritation and liver and kidney damage. Products can emit VOCs even when they’re in storage.

Carbon Monoxide

This is a high concentration colorless, odorless gas. Fuel-burning appliances generally release it. This gas can cause adverse reactions, including confusion and memory loss. 

Carbon Dioxide

The most significant source of indoor CO2 is people themselves, as it’s a byproduct of our respiratory function. Coupled with poor ventilation, this commonly leads to high levels of CO2 in many homes. Fortunately, you can find CO2 sensors on most air quality monitors.

Radon

It is a naturally occurring colorless, odorless gas that is a leading cause of cancer. 

It’s a byproduct of the naturally occurring breakdown of uranium in soil, rocks, and water. It’s ubiquitous both indoors and out. Typically, indoor radon levels must be checked using charcoal-based kits and require you to test your classes for up to 90 days. You then need to ship the equipment to a lab for analysis and wait for the results.

An indoor air quality monitor with a radon sensor can provide faster results by monitoring levels in real-time. Currently, the Airthings Wave is the only monitor in our guide with this capability.


Air Quality Index

0-50

The color of the air quality monitor blinks ”Green”. The green color means ”good” or the air quality is ”satisfactory”. The air pollution poses is low or at no risk.

51-100

The color of the air quality monitor blinks ”Yellow”. This color is a sign of ”moderate”. The EPA(Environmental Protection Agency) defines this level as ”acceptable”. However, this can be a risk for middle-aged or people who are unusually sensitive to air pollution.

101-150

The color of the air quality monitor blinks ”Orange”. The EPA suggests this air quality is less likely to affect young people. However, those people in sensitive age groups can be affected by this air quality level.

151-200

The color of the air quality monitor blinks ”Red”. Both the “sensitive groups” and the healthy population can be affected by this air quality level.

201-300

The color of the air quality monitor blinks ”Purple”. This range indicates there is an increased risk of health for all populations.

301+

The color of the air quality monitor blinks ”Maroon”. Try to stay indoors. This range is classified as a “health warning or emergency condition” that could impact everyone in the area.
