6 Best Air Quality Monitors for Home 2021

According to The World Health Organization statistics, about 4.2 million deaths are caused by exposure to ambient outdoor air pollution annually while 3.8 million deaths are caused by exposure to smoke from dirty cookstoves indoors annually. Studies have also found that we spend 90% of our time indoors. This means that there is a need to optimize the quality of air in our indoor spaces not just for comfort but also to remain in good health.

However, when you notice that your nose has all of a sudden started to itch, you start sneezing, have trouble breathing, or are experiencing other respiratory-related problems, it’s a cinch that the air you are breathing is polluted. Sometimes, according to The EPA, indoor air can be two to five times more polluted than the air outdoors. Some top common indoor air pollutants include

  • Radon. Naturally occurring radioactive gas that is odorless, colorless, tasteless, and dangerous if it occurs at high levels.
  • Carbon dioxide (CO2). Trace carbon dioxide molecules will always be present in the atmosphere. Exposure to concentrated levels of carbon dioxide can cause drowsiness, headaches, high blood pressure, and other effects.
  • Volatile organic compounds (VOCs).  These include toxic chemical compounds found in the air like benzene, tetrachloroethylene, xylene, toluene, formaldehyde, and methyl chloride often from petroleum fuels, paint thinners, and varnishes, dry cleaning products, and others.
  • Too high or too low humidity levels. Very high humidity breeds molds indoors and very dry air can cause cold and flu. The optimum indoor humidity level as recommended by The EPA is between 30% and 59%.
  • Very high or very low-temperature levels. This interferes with sleep patterns, concentration, and overall comfort.

For this reason, it is vital to consider investing in an air quality monitor indoor, outdoor, in your car, hotel room, or in whichever space you find yourself. An air quality monitor is a device used to measure the level of pollutants in the air.


What should you consider when buying an air quality monitor for your space?

There is a wide range of air quality monitors for sale and getting the right one will be determined by the specific features that you are looking for in a monitor. Here are five questions you will need to ask yourself during purchase.

  • Which elements can they measure? Different spaces have different air quality concerns. Most devices are designed to measure VOC, Radon, CO2, particulate matter, temperature, and humidity. Select a monitor that can measure the right combination of pollutants that are a hazard in your space.
  • How accurate are air quality monitors? Accuracy is the ability of an air quality monitor to consistently give the right readings. This is a very important factor in air quality monitors for home use.
  • Can they be used both indoors and outdoors? Some monitors are designed exclusively for indoor use while others can be used both indoors and outdoors. Where do you intend to use your monitor?
  • How portable are they? Outdoor air quality monitors should be portable. This means that they should be compact in size and come with inbuilt rechargeable batteries or be powered by dry cells.
  • Do they have smart capabilities? Should be able to connect to your smartphone for convenient use via an app or online through the phone. This is usually through Bluetooth connectivity or for some, waving the device in front of your phone. Still, some are compatible with digital assistants like Alexa, Google Assistant, or IFTTT (If this, then that).
