The Best Air Quality Monitor

Indoor air is sometimes more polluted than outdoor air. Why is that? Well, one primary reason could be that many of us don’t even consider that it’s possible. As a result, we don’t pay enough attention to the quality of our indoor environment.

The problem is that we are incapable of directly sensing many of the common issues in air quality, like dust, humidity, fumes, and emissions. It is precisely why an air quality monitor should be a staple in all modern homes. An air quality monitor will help you ensure that your indoor environment remains healthy.

But, due to their vast availability, it can be challenging to choose the right one. So in today’s guide, we have listed and reviewed the top 5 best air quality, monitors.

The Foobot is intended to work an air quality monitor for home. It means it is not just meant to give absolute values and percentages of substances in the air.

On the contrary, it understands that what you need are practically applicable readings, instead of absolute data. So it has preset tolerance for about 20 percent. It allows the monitor to send alerts only when there is an unusually high percentage of a substance in the air. Better yet, it does not throw random figures at you to cause unnecessary stress. On top of all that, the Foobot helps you identify long-term factor affecting your air quality by identifying patterns over time.

This long-term assessment is excellent when it comes to identifying long-term underlying factors that affect air quality. For example, you may be able to tell that a specific cleaner you use is damaging air quality if you know that a particular trend emerged around the same time you started using it.

  • Saves you unnecessary stress by relaying relevant and practical information
  • Identification of trends helps you narrow down factors affecting air quality
  • 6-day warm-up period allows the device to acclimate itself to your home
