BIAOLING Multifunctional Air Quality Monitor

Our Expert Score


Our Take

Portability is important, which is why this air quality monitor has a built-in rechargeable battery. Homeowners can check several rooms with the device, as well as hotel rooms when on vacation. The monitor has a large LCD screen the reports on carbon dioxide, formaldehyde, volatile organic compounds and particle matter.

Our Buying Guide

It’s estimated that most people spend 90% of their time inside. That means almost all the air we breathe throughout any given day is indoor air. It makes sense then to learn exactly what is in the air that we breathe and what the levels of those potential contaminants are. Once a person is armed with this information, he or she can take steps to change the environment for the better.

Air quality monitors are now made for home use, but you’ll need to do your homework before deciding on a specific model. This is because not all air quality monitors test for the same things. Some models are also more tech-savvy, which may not be ideal for those who prefer a simple readout that is easy to understand.

Start off reviewing which contaminates the air quality monitor is capable of identifying. For example, the BIAOLING Multifunctional Air Quality Monitor tests the air for formaldehyde, total natural and synthetic volatile organic compounds, carbon dioxide and fine particulate dust matter. Other monitors also track the temperature and humidity of the air, as well as the air pressure and ozone levels.

Determine whether you need a stationary air quality monitor or one that is more portable. Some models can actually be used for both purposes, as they have the ability to spot-check a hotel room or continuously run for two days to provide you with a more accurate picture of the air quality in your bedroom.

Look at how the results of the air quality test are provided to the end-user. For example, some monitors are more simple to use and feature an easy-to-read LED display. The units are color-coded with green indicating that the air quality is good, yellow revealing moderate air quality levels and red showing that the air has reached unhealthy levels.

Individuals who are more tech-savvy and who prefer a more detailed report will want to go with a unit like the Awair Element Indoor Air Quality Monitor. This device connects to an app on your smartphone, so you can log in and review your results. The app is also able to provide feedback and helpful tips to improve the health of the air in your home. The device is even compatible with Amazon Alexa and Google Assistant. Other models also work with Nest and Roomba.

Simplemost Fun Fact

Did you know that since the year 1990, the Environmental Protection Agency (EPA) has listed indoor air pollution as one of its top five public health risks? In fact, the organization points out that there are an astounding 1,000 different pollutants in the air that could be making you sick. It’s no wonder there are over 50 million Americans suffering from allergies each year.

Some of the most common pollutants found in the home include cigarette smoke, mold, dust particles, carbon dioxide and volatile organic compounds (VOC). VOCs include everything from formaldehyde to pesticides to the odor that is emitted when you sauté onions. They even encompass your body odor.

If you’re concerned about the air quality in your home, the first step is to purchase an air quality monitor. This is the best way to learn which of the above pollutants are plaguing the areas where you relax, spend time with your loved ones and sleep. Armed with this information, you’ll be able to make important changes, such as replacing your home air filters or installing an air purifier in the rooms most affected.

The Tips and Advice

  • Air quality monitors that are powered by wall adapters often have cables that are difficult to hide.
  • Some air quality monitors pair with a smartphone app, so look for compatibility with your phone’s operating system when making a purchasing decision.
  • Most air quality monitors do not test for things like carbon monoxide and mold, so you’ll still want to install carbon monoxide detectors in your home, too. If you suspect you have a mold problem, you can also buy mold detection kits.
  • You may find some air quality monitors are off by a couple of degrees or micrometers. For the most part, this isn’t too much of an issue. If you need more accurate results, however, you’ll want to invest in a more top-of-the-line model.
  • It is important to note that some air quality monitors run loudly, while others are much quieter. If you have an infant at home or you consider yourself a light sleeper, you may want to search for a quiet model.
  • Some air quality monitors are battery-operated. You’ll need to check whether the batteries are included or whether you need to purchase them separately.
  • Portable air quality monitors can be used to test the air quality in your car, office, basement or hotel room.
  • If you suffer from severe allergies or asthma, an air quality monitor is an excellent investment. You’ll have the information you need to keep your attacks to a minimum. For example, if you notice the dust matter levels rising, you’ll know it’s time to change your home air filters.
  • Monitors that connect to an app on your phone are often able to track the changes in your air quality over a specified period of time. This is a great way to identify any unhealthy patterns, so you can make any necessary changes.
  • Some of the apps used in conjunction with the air quality monitors are only compatible with 2.4 G Wi-Fi. They won’t work over Wi-Fi or 5.0GHz connections.
  • Many of the monitors can also be taken outside to get a snapshot of the air surrounding your home.
  • Air quality monitors vary slightly in price based on their design and integration with today’s technology. The BIAOLING Multifunctional Air Quality Monitor comes in at an affordable rate. Both, the Huma-i Advanced Portable Air Quality Monitor and the Awair Element Indoor Air Quality Monitor, are moderately priced. You’ll pay more, however, for the Airthings Radon Air Quality Monitor, which works with Alexa, Google Assistant and the app on your phone.
