It is accurate and showing low level of CO. This morning it was in the yellow region. I got worried and started looking in the house but then realized here in Colorado we have 4 raging fires in our foothills. So I guess it works too good.

I have the Temtop M2000 hand monitor. I added this model because it has a longer battery life so I can leave it on all night hoping to get alerts if the C02 goes into a red zone. The readings between the 2 monitors differ by over 100 ppm so accuracy is questionable. Also this model doesn't have a backlight so you can't see it during the night unless you turn on a light. At this price point I can deal with not having a light but I'm not sure which of the 2 monitors is most accurate. Customer Service is excellent and responsive but we were not able to solve this problem. Since the monitor hasn't gone into the red zone I can't say whether or not the alert works. I'm keeping it but can't give it 5 stars.
UPDATE: I recalibrated both monitors and they are syncing more often now, to within 50 ppm. The long battery life is impressive but this monitor rarely goes over 800 ppm when the handheld monitor is beeping in the red zone at much higher levels. Not sure why this particular monitor doesn't go high enough to hit the buzzer. Since the handheld was tested and approved by EPA I trust it more. For the price point this monitor is adequate but if you have issues with high C02 levels I recommend getting the Temtop handheld.

Ich wollte das Gerät eigentlich gleich nach dem Auspacken zurückschicken, da nach dem ersten einschalten das auf dem Bild gezeigte 5000 ppm erschienen ist. Da müsste ich ja binnen Stunden in meiner eigenen Wohnung schon in Ohnmacht fallen... Dann die Kalibrierung gestartet, danach immer noch der gleiche Wert. Erst nach der Kalibrierung nach ca. 3 Stunden ist dann mal ein normaler Wert herausgekommen.

Seitdem habe ich das Gerät in meinem Gärkeller und es zeigt plausible Werte an. Jedoch habe ich es mal in den Gärschrank kurz hineingelegt und es waren in kurzer Zeit auch wieder die 5000 erreicht. Jedoch macht mein Gerät keinen Ton, dass obwohl der Modus aktiviert ist. Keine Ahnung ob mein Gerät kaputt ist oder der Lautsprecher gar nicht eingebaut ist.

I turned it on and just like expected we had a very high co2 reading. Over 2600 ppm
I was sceptical so I put it in an open widow and it dropped to low 400
Now we have installed a new ventilation unit and we’re good and actually feel better

Vine Customer Review of Free Product( What's this? )
I never even considered monitoring the CO2 level in our home until I found this portable monitor. We have air purifiers in various locations so I assumed the air quality was good but didn’t consider the oxygen and CO2 levels and how it could affect us. Apparently, exposure to too much CO2 can affect both your brain (lack of concentration, headaches, and even slowed cognitive functions) and sleep quality. Unfortunately, this device doesn’t monitor VOCs (volatile organic compounds), but hopefully, the air purifiers will help.

This monitor gives you pretty accurate insights into how healthy the air is in your home or specific rooms. The crazy thing is that the CO2 level can change over a short period of time and you wouldn’t notice it, unlike a temperature change. Fortunately, this monitor even has an alarm when the CO2 level reaches unhealthy levels.

You get a nice 55cm x 65cm LED display that’s easy to read and understand showing you the CO2 level, temperature, and relative humidity. I like that there’s a color bar that runs under the CO2 level and the indicator level arrow moves between the green (good), yellow (average), and red (unhealthy) segments in addition to the numeric display that shows you the CO2 level in ppm.

It was interesting or a little alarming that the CO2 level was in the yellow when I started working in my office and with the door closed and I watched it slowly climb towards the red! Yikes! In about 15 minutes after opening the office door, it came back to the mid-yellow area.

There are 2 vents, one on either side that monitor the air quality. You can select the Auto mode which will sample the air every minute or the Eco mode which will sample the air every 10 minutes (and will prolong the battery life… up to 70 days). Charging it is done via USB-C and it still works while charging.

It has a nice design feature with a magnetic back so you can attach it to any metal surface plus you get a little stand with a metal plate so the monitor snaps to it and can be placed on your desk/bedside table and with it being so compact, it’s easy to move from room to room for testing. I think it would have been nice to have the option to hang it too.

I think this CO2 monitor is an essential device to keep your home air safe and healthy and I would definitely recommend it for your family’s well-being.
