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.

strange smells in home ,always not feeling well purchased to check air quality ,found all to be within parameters I am now happy to rule that out.

Won't sense below 32° F, but other than that I like it

Very useful. Worth the price. .

I Love Temtop products, I also own the M10i but this M10 Plus is a big step up compared to the frustrating M10i.The biggest improvement on the M10+ in my opinion is the battery life compared to the M10i it's night & day. The M10i wouldn't last one day but I have my M10 Plus running for a week and it hasn't dropped a bar. In addition the M10+ uses USB-C compared to the outdated Micro USB of the M10i.The product page claims the battery can last up to 60 days, I haven't own it for that long so I can't confirm that but already I'm impressed with it's battery longevity, I can leave it anywhere in my home without having to worry about charging it every day.The M10+ doesn't measure HCHO unlike the M10i but what it does that the M10i doesn't is :CO2 LevelsTemperature and HumidityTimeFirst the time is a simple, yet useful addition since allowing the device to act as a clock.Temperature & Humidity are 2 great additions it eliminated the need for a 2nd device to measure those things that are important for the overall comfort of your home. From what I can tell by comparing the reading of the M10+ with a standalone device, the temperature & humidity reading are accurate.The addition of the CO2 monitor is also a great improvement and from my testing you can see how well it works when I ventilate a room by opening a window for example you can rapidly see the levels drop.Also it uses Bluetooth connectivity instead of WiFi (might of been one reason for the poor battery performance of the M10i) The Bluetooth works well, but it doesn't seem to stay on, the Bluetooth seems to turn off after some time of inactivity so when I open the APP to connect to the device I often need to press the button on the back. This might be a power saving feature.The display is easy to read even in relatively low light, but there's no backlight so you can't read it in the dark. Again this is probably a power saving decision, but a button to turn on a temporary backlight would of been nice. One thing about the display I like is the addition of a colour coded bar (Green, Yellow, Red) you can quickly & easily know if your reading is good (Green) fair (Yellow) or poor (Red).The device is easy to operate, there's just one button, a long press will turn it on/off a single press will change to change what is being currently displayed and cycle through the readings. Finally a rapid double click will start a cycling mode where each reading will display for a few seconds (about 6) and then change to the next one in a constant loop. There's also one button in the back to turn the Bluetooth on.The APP is okay, it works well it's the same APP as the M10i so if you have multiple devices you can all access them there. On the main screen you see at a glance all 6 readings from the M10+ you can click on one an see a graph of the fluctuations during the day. You can have weekly & monthly graphs.The data can also be exported into an xls format.The device is fairly small and compact and can be place pretty much anywhere.Overall this is a great air quality indoor monitor and a huge improvement on the M10i, the extra 40$ is well worth it in my opinion.

I was quite pleased with this air quality sensor. We live in Florida and suffer a closed house for most of the year. So being how long we live in AC with little fresh air I was expecting the air quality to measure poorly. Surprisingly it measures pretty well. The APP gives good data plots on each factor, and the sensor response to change is quite impressive. One afternoon we were cooking a dish that smells up the house, so we lit a candle, Within minutes the PM started climbing along with the VOC. The battery truely does perform well. I've ran it for days right out of the box and have plenty of charge left. It's not a large device, about the size of a pack of cigarettes. I recomend it. Buy one of these and measure the AQI before you spend a bunch of money on air purifiers. I found I don't need them.

The marketing for this product discribes itself as "meticulous" and "real time" to imply it is fast to respond and doesn't miss anything. I have sat infront of a fire for close to 30 minutes now and it's still saying the air is clean. It seems to turn on once every hour takes a few samples then turns back off missing everything between. It's rather useless for everything but long term averages in a static environment. Also find the claim of "comprehensive" alarm to be funny. It has 1 toggle for the alarm, on or off. That's it, it in fact could not be simpler. You can't even change what reading the alarm goes off because of. Rather disappointing for 130$. I will be returning it most likely. Much better is available for slightly more and the same quality is available for lessOne thing I can say is the co2 sensor seems real and isn't a virtual one. It's difficult to see how it responds to tests because it doesn't respond to anything for nearly a hour

This product potentially just saved my life, I was always curious of the quality of air in my room but never really wanted to delve into the complication of understanding how air quality affects your overall health and what products can help me check the quality of air in my room.Maybe I was just lazy or just had other stuff going on in my life. And that was a grave mistake I was making without really knowing about it either.Once this product arrived it came with the monitor itself, along with usb type c for charging and a user manual for the basic information needed for using this device. I checked the user manual for all the information this product has to offer.This product monitors temperatures, humidity, CO2 (Carbon Dioxide), VOC (Volatile organic compounds), and PM2.5 (Fine particulate matter).The product can be set up to your phone using Bluetooth but doesn’t require it. Once I plugged it to a power source it immediately started giving information for temperatures, humidity, CO2, VOC, and PM 2.5.To my shock, my room was extremely high in PM2.5, CO2 and overall the quality of air in my room. I immediately used an air purifier as soon as I could and over a couple of hours I notice the quality of the air get better and better.Upon researching the harmful affects of CO2 and PM2.5 I really regretted not using a product like this sooner.One disclaimer to note is, this product does mention if the quality of air in poor in the area. It is recommend to turn it off and place in a safe area due to the particles potentially giving an inaccurate reading later on.Overall this product is definitely recommended. I do want to also recommend researching products like these more and finding the best value because to some it does seem to be expensive. But if it’s potentially life saving, I would say it’s definitely worth it.

The Temtop M10 plus is a solidly built unit and has a very clear and easy to read front display. The on/off button on the top is easily accessible as well.Once turned on I started getting reading right away but waited a couple of weeks to compare against an air purifier as well as another testing device to see if there were any variances. To my surprise the unit was very accurate and the differences between units was only 0.2 in measurements, particularly VOC, Temp, Humidity. Battery wise, its still going from its original charge over 3 weeks ago!The one thing this unit did have was a CO2 level reader - which my other units did not have. This was an eye opener! The CO2 levels in my basement were quite high and caused me to look at the air circulation and change up ventilation in the house. I've since rectified the situation and the levels are normal again, but I would not have known without this unit.The only gripes I have with this thing is that it doesn't connect to wifi and requires you to push a button to connect the app on your phone via Bluetooth. The button should be placed on the top of the unit for easier access.Other than that, very happy with the sensitivity and the sensor measurements that the unit provides!

The tech is very impressive. It uses E-ink tech, not a screen, so it can be hard to read under dim lights but otherwise is super cool. It not only can tell air quality, temp, and humidity but it also has a clock as well.Easy to set up and worked right out the box. Took around 10 minutes to calibrate. However if you move it to a new room, it can take 1-2 hours to re-calibrate depending on the temperature difference. It calibrates very slowly. For example I moved it from a very hot upstairs (31C) to an A/C'd room (23.5C) and it took almost 2 hours to slowly get to the right temp.As far as accuracy goes, it seems fairly accurate. I put it next to my Ecobee unit and it was off by 0.4C. The humidity was off by about 8% though. You can manually fix this on the phone app if the difference is too big. The only big error was the CO2 reading....it was in the red and showed over 1,500 but I asked it to re-calibrate on the phone app and it fixed itself.It does not display TVOC, CO2, AQI, PM2.5 all at once. It will only display a single air quality results at a time. You can choose to have your preferred air quality test always displayed or cycle through each one. You don't need the app to do this.The graphs that come with the app is neat, showing you the changes throughout the day.The battery life is very long (30 days) and easily rechargeable via usb-C.So despite it's impressive tech, it's hard to recommend for the following reasons:- Very pricey for a temp/air quality device. For over $200, you can get a air purifier that can do all the readings as well as filter the air. Or off-line devices that has all the same readings for less than half the price.- It only has bluetooth. You cannot remote monitor with this as there is no wifi/internet connectivity. The bluetooth automatically turns off when not in use (Most likely to save battery). Each time you open the app, you will need to manually turn the bluetooth on by pressing the bluetooth button on the device.- You are required to make an account to use the app. And it is not a "create with G+/FB/etc.", you need to manually make an account and password.- An account is required for a fair amount of features. This includes changing from Fahrenheit (default) to Celsius. Re-calibrating, turning off sound alarms, manual adjustments to calibrations, etc.- This is currently the most expensive model from the seller but it is also oddly missing features from cheaper models. For example, the cheaper models have HCHO monitoring and WiFi for remote access. Yet this is significantly more expensive but does not have those features.Overall it is a neat and great device. It is hard for me to justify based on the price. If you just need temp/humidity monitoring, there are basic devices for around $10-$20 and works about the same. If you need air quality monitor, there are air purifiers that can do it (Albeit takes more space). Chances are if you need a small device to monitor the air quality, you would want something with WiFi so you can remote monitor which this doesn't have.The features to price ratio for this makes it hard to recommend for most people unfortunately despite the impressive tech. At this price, remote monitoring is absolutely needed to make it worth it. There are offline models for less than half this price, you would essentially be paying $100+ extra for just the graphing features on the app which is not worth it imo.

I have an older version Temtop CO2 meter and this new one has a much more readable display and the CO2 levels that it shows are much lower. I tend to trust the newer one because when calibrated outside it reads 400 ppm which is what it should be.I was really looking forward to the ability to track CO2 over time but the app makes this virtually impossible. When you tap the current value in the app it shows a graph of hourly values from midnight to the last hour. There’s a back arrow and when it is pressed a graph from 2 days ago is displayed. When the forward arrow is pressed nothing happens.The app also has difficulty maintaining the Bluetooth connection and it sometimes displays a 401 authentication error. The iOS App Store states that no data is collected by the developer but it is troubling that you have to create an account and be logged in to use the app.For $80 I expect the app to work better and more reliably.

Highly recommended
