​Buyer’s Guide: What to Look for in an Indoor Air Quality Monitor

Before you spend any of your hard earned money (whether that’s online or in person), there are a few things to look for in indoor air quality monitors. Take some notes in this section to make your shopping experience a bit easier. This will allow you to quickly find which products will or will not work for you.

A few of the things you’re going to want to keep your eye out for are the following:

  • ​Humidity and Temperature
  • ​VOC
  • ​Wi-Fi Connection
  • ​PM
  • ​Price
  • ​CO2

​Let’s talk about each one of these sensors in a bit more detail.

Humidity and Temperature

When it comes to indoor air quality, the humidity and temperature in your home play a big part and monitors that test these two things are some of the most commonly found products. The monitor will be able to tell you if it’s too humid which can make mold grow or cause dust mites which can cause allergies or asthma attacks. The monitors that test the humidity and temperature also save you money from having to buy extra sensors to test those things. If you suspect humidity to be low - or verify it with a monitor! - consider purchasing a whole house humidifier or a cool mist humidifier to resolve this issue.


​Some monitors tests Volatile Organic Compounds (or VOC). These are gaseous pollutants that can be very harmful to our overall health. Have you heard of Formaldehyde? This is one of the more popular Volatile Organic Compounds and can be found in things like glue and garden fertilizer. Monitors with this type of sensor are some of the best on the market.

Wi-Fi Connection

​Having an indoor air quality monitor with Wi-Fi connection can be a big plus if you’re a fan of electronics. This way, you’ll be able to see the results of the monitor right at your fingertips using your smartphone, tablet or laptop. This is merely a preference but a lot of folks like the convenience.


​Some monitors will test particle matter or PM. Particle matter is something you can’t get around, it’s quite literally everywhere. Things like dust or pollen are considered particle matter. When we inhale these things, it can affect our lungs and breathing. You’ll find that the monitors that read PM give you a concentrated number for a specific time period. These are best used for things like seasonal allergies.


​Just like most other things you purchase, price can play a factor. Luckily there are monitors available at just about every price range. Some have features others don’t but it’s good to keep in mind that just because an idea is cheaper, doesn’t mean it isn’t good quality. Just like how more expensive items won’t always have features the more inexpensive ones do.


​Though CO2 is found naturally in the air, when levels are too high it becomes dangerous. There are air quality monitors that use a Carbon Dioxide sensor to help show you the levels for air quality purposes. These could double as C02 monitors, saving you money from buying another product.
