M10+ Indoor Air Quality Monitor, 6-in-1 CO2, PM2.5, VOC Detection, Smart Temperature & Humidity Sensor, with App Connectivity for Home Air Quality Testing & Analysis

I’ve been using the Temptop M10+ for a while now, and I’m really impressed with how well it performs. The accuracy of the readings is spot on—I’ve compared it against other monitors and it’s consistently reliable, which gives me confidence in the data I’m seeing. The battery life is fantastic. I can run it for long stretches without worrying about constant recharging, which makes it super convenient whether I’m using it at home, in the office, or while traveling. I also love the display—it’s clear, bright, and easy to read at a glance. The layout is intuitive, so I can quickly see all the important information without fumbling through menus. Overall, this device has exceeded my expectations. If you’re looking for a dependable air quality monitor that combines accuracy, long battery life, and an excellent display, the Temptop M10+ is a great choice!

This is a very good product. I moved to another state that has poor air quality and I had some breathing issues. I am using this all the time to check and adjust the air quality in the house. It really seems to work well and the charge is amazing. I have had it since October and have had to only charge it twice. The first time I just took it out of the box and just starting using it. The display on the unit is very easy to read and you can make several adjustments to customize it for your liking. It has alarm sounds so if you want to have an alert when something needs your attention it will do that. Clock, temp and humidity is very nice feature as well. The app is absolutely a plus as well as it tracks your air quality over time. This unit for the money will be well worth it for years of service. It may cost a little more but I have gone through a few that only last days before the charge just gave out. Nice materials for the outer casing it used as well and just sitting on our fireplace mantel it just fits in with the room.

The app doesn't do a whole lot feature-wise, but the device on its own is great. Lasts an eternity on a full charge! EDIT: I noticed that if you set it to constantly rotate through the different measurements, the battery drains much, much more quickly. I just leave it on CO2 PPM and it can go weeks without a recharge. If I want to see other measurements I either manually switch on the device itself, or check the app.

Bought the device for the CO2 sensor, which can be calibrated for accurate readings. Had suspected that the bedroom may be “stuffy”; after the first night, the sensor had readings close to 2000!. From that point on, kept the window slightly open and that made a big difference in the readings, e.g., unhealthy to good. In my mind, the other sensors are an added bonus, and I primarily look at the VOC, PM2.5 and AQI readings. They seem to stay in the healthy or moderate range. The only thing missing is WiFi connecttivity; you connect via Bluetooth with your phone or similar. More expensive than the “inexpensive” devices sold; but the sensor technology seems to be of very good quality. If you need a CO2 sensor and others, I would recommend this device!

Worked great until last week. It completely stopped working. I contact their support to see what’s wrong with it. No help from them given that I bought it a year ago.

Neat tool for checking air quality. I knew the circulation I my room was bad, but I didn’t know it was this bad until checking. It let me know what was bad so I could take steps to improve it. I was happy enough that I got a second one for the garage to alert me if the air quality drops or the temp and humidity are out of range for some work. At the time of writing this, you don’t need the app if you don’t care about the data tracking or time. If you still want to use the app, you can just use a guest account. It’s nice to know if you don’t want to keep giving companies your information.

Was really an eye opener for the co2 levels in my house which led me to getting better sleep by changing the air circulation. Also was helpful in making me aware of the ppm and poor air quality after cooking which again helped when I improved the fresh air circulation.

I don't think it is terribly accurate, I was able to compare it to another device that costs more (a neighbors) but it was within the range enough for the price point, I wouldn't have paid what my neighbor paid, I just want to have a reasonable baseline.
