This year, it would seem that everyone wants to buy an air quality monitor. Which is a good thing as it raises awareness of the air pollution problem. But which one to buy and where to buy it? Prices vary a lot and they each have their own advantages and disadvantages. In addition, can you really trust them to do a good job? Particularly if they are so cheap? As people keep asking me where I bought my air quality monitors from, I thought I would gather information together on this one page to help answer that question. At this moment I am not saying which ones I like the best. But, as I gradually start doing reviews of these monitors, I will also add a star rating with pros and cons for this page.
