How Do I Choose the Best Air Quality Monitor?

Many people spend almost 90% of their time in closed spaces such as offices, shops, restaurants; some people hardly ever leave their own home. The quality of indoor air can be 5 times more toxic than the outdoors air, which can have a big impact on your health. Experts have identified about 8,000 chemicals that contaminate the indoor air, the most important pollutants being CO2, cigarette smoke, radon, asbestos and biogenic particles, odors and humidity.

All these toxic agents in your home can affect your health; they may aggravate your existing conditions such as asthma, allergies and other respiratory problems, causing headaches, eyes and skin irritation, sore throat, colds and flu, memory loss, dizziness, fatigue and depression. More dangerously, the long-term effects of exposure to toxic particles in the air may include heart disease, sterility, reproductive dysfunctions and more.

Air quality monitors are really useful in any home as they show you the CO2, humidity and temperature levels. If you feel humidity in your house all the time you should consider getting a dehumidifier that’ll extract the excess moisture in the air. Similarly, a ceiling fan would be a good idea if you want to vent the air in your house a little more with just the push of a button. This is good for indoors, but it’d be great to improve the air quality in your car too. To this end you can use a car air purifier that removes odors, pet hair and other particles in just a few seconds.
For the most part, air quality monitors with the standard features are affordably priced, unless you’re looking for a high-end product that can be used in large spaces or industrial areas. A good air quality monitor starts at around $30 and can go up to $500 for one made of durable materials that’ll be with you for a long time.

There are also cheap air quality monitors on the market, but we advise you to ignore them as they don’t give accurate readings and are made of poor quality materials. They’ll also likely end up costing you more in the end, too, given their tendency to break down early.
Air quality monitors are user-friendly devices that help anyone measure the levels of carbon dioxide inside their home. They can also measure the temperature and humidity levels. These devices have multiple other built-in features that make them function properly. Check out the most important ones you may want to consider before making a purchase:
  • Multi-use — Air quality monitors should be used for multiple purposes such as measuring temperature, humidity, toxic particles and CO2 levels
  • Accurate — They should give highly accurate readings and alert you when something is wrong
  • Display — Air quality monitors should have an easy to read LCD where it displays all the readings
  • Mounting technique — These devices can be placed on your desktop, on a shelf or wall mounted
If the air quality monitor you’re looking to purchase is made of good materials and looks durable, you certainly won’t have to worry about it breaking down any time soon. Read on to learn about the construction and design aspects of an air quality monitor.
Construction and Design
Air quality monitors are usually made of plastic and can be placed on your desktop or mounted on the wall. Before getting one decide where you want to place it and choose the one that fits. The style isn’t really an issue when purchasing such a device because it isn’t that important. What is important about it is to be accurate, to include multiple readings such as humidity, temperature, dew point and if it works on batteries and, if so, whether it has a good battery life. Most of the air quality monitors come in circular or rectangular designs and are usually featured in white or black to easily blend into home or office decor.
Performance and Ease of Use
No matter what air quality monitor you will pick, be sure that it’s multi-functional and can also read the humidity and temperature levels, in addition to the CO2 levels. They’re really easy to mount and to install, but if you have troubles with them you can look at the user’s manual they come with.
