Without access to calibration equipment it is of course inpossible to tell the accuracy of the device. But readings closely follow environmental changes increasing / decreasing particle levels such as cooking, applying an air cleaner, vacuum cleaning, opening / closing windows etc.Measuring continuously over a couple of weeks shows patterns of variation corresponding to the changes we make (windows etc.) over the day. Measuring like this has also provided us certainty about the efficiency of air cleaning ( we use an Electrolux EAP300) which is able to reduce PM2.5 and PM10 to near to 0 levels in about an hour. The data export feature is very important and works well. I miss separate particle counts for OM2.5 and PM10, though. Logically, there must be separate counters for the two particle size ranges, so why not let the device display the separate counts instead of pooling them?

Accurate and easy to use. Battery lasting longer than I thought it would.

I saw an YouTube video with a guy testing the air quality on the tube in London (which as it turns out is very unhealthy) and wanted to test it for myself and also wanted to see what is the air quality is in my office and at home and I was shocked. I am seriously considering wearing a face mask again on my commute to work as breathing the air in the tube in London is worse than smoking. At least the air on ground level (12-15 AQI) and around where I live in Loughton (7-10 AQI) is safe. I like the temperature and humidity functions and the ability to export the data so you can see the change over longer periods. The price is high but I hope this monitor lasts at least few years.

hello in short i have found it easy to use and data easy to interpret. only issue is could the print be in a larger font on instruction paper work?

This is a brilliant bit of kit. Very accurate readings of air quality and serves up some surprising results, even in the home, esp the kitchen when cooking underway.
This unit has also proved that London has perfectly healthy air quality and that the powers at large are using propaganda to fleece the proletariate ULEZ my Backside!!!! Thanks to Brown Car Guy, I have this unit and another weapon to undermine the conspiracy theorists!!!
