I know, I know I haven’t updated the list for quite a long time. The main reason is the lack of innovation lately. Also, many companies have shifted their attention and they have removed their products from the market as they don’t have the desirable sales. It doesn’t make sense for new companies to reproduce the same air quality monitors with the same sensors and technology inside over and over again.
I feel the saturation is noticeable nowadays. However, a change is happening and I see it unfolds in front of my eyes.
Anyway, remember there are two tabs; Air quality monitors for consumers (B2C) and for businesses (B2B). As always, I stay away from knockoffs and cheap products. An air quality monitor needs to function properly for 5 to 10 years depending the sensors − gas sensors tend to have a shorter lifespan. Keep in mind, it doesn’t matter how many sensors an air quality monitor has as long as the implementation has be done correctly.

Thank you for your contribution. The provided spreadsheet is very informative. I have a query regarding the inclusion standard applied. I observed certain low-cost sensors was not included in the table.

Thank you very much for the website which I just found after a few days researching which air monitor to buy. Can I ask, some monitors say they monitor PM1.0 particiles, but there isn’t a box for this on your spreadsheet .. is this an important measure at all? Also is there a particular monitor that would be recommended by anyone right now, or as you say about current ‘innovation’ is it best to wait for something on the horizon? Many thanks

Hello, you don’t need to wait if you need something today. Stick with your choice if it meets your requirements. Regarding PM1: Mass concentration values for sub-micron particles don’t reflect the real impact these particle sizes have on human health because their mass is so small and the values they give per μg/m3 are also small numbers. Nowadays researchers are trying to find a better way to express the sub-micron particles and particle counts per size is one of them. Thank you for your support.
