   Clear display, easy to use

   I was shocked to discover the air purity is reduced so much when room not being ventilated. It’s made me so aware of the importance of opening windows and doors.

   Co2 levels … what’s not to like?

   Arrived and set up easily, it gives a reading once calibrated that seems accurate- mind you, how would you know?Sits at around 400+ppm which is atmospheric. However, and the point is, it goes up over the course of sitting in your kitchen wherever of an evening, and starts to glow orange [rather than green] at about 700 ppm which may ‘induce you do something about it’. Options vary at this point, but I’d heard that over 1500, [red] should definitely mean you’re outa there smartish.Will operate for several hours unplugged in to power source , longer if display [ zone indicator light still shows] is off.Is fun and slightly puzzling and disconcerting how it can still be raised above 500 in a downstairs room, first thing of a morning. And nice to see a bedroom level [dual occupancy] isn’t through the roof in the middle of night.Humidity and temp not quite the same as my separate temp-clock-humidity meter, which considering is not this unit’s main purpose is acceptable to meDare I sneak it into the pub?

   Would recommend

   Very clear display, a quick glance gives you all the information you need. Have tried it in different rooms and environments and found it to be quite accurate, for instance travelling in the car ,sleeping with a window closed, at a social gathering etc ,rather pricy but very beneficial to see the quality of the air we breathe.

   Easy to use, worth the price.

   Very easy to use straight out of the box. I found out what the reading for fresh air was (around 400ppm) then used it in a closed room with people. The readings went dramatically up over an hour (900ppm) then I opened a window and the levels dropped back to around 400ppm and stayed there. Which proves that opening a window really does refresh the room.This may seem a pricy bit of kit, but it is helping me prove to folk how to avoid potential Covid build up in an unventilated room, but at the same time reassuring others that measures to ventilate are working.
