This is a review of the Qingping Air Quality Monitor Generation 2. My review of the Generation 1 Qingping Air Quality Monitor is here.
I was impressed when I first reviewed the previous version of the Qingping Air Quality Monitor. For $129, Qingping had somehow created an indoor air quality monitor that combined good components with an exceptional touch screen, making it probably the most pleasant monitor to interact with and use that I’ve featured on this website so far.
When I found out Qingping released an updated monitor, I was astonished and excited. My surprise stemmed from seeing Qingping sticking with air quality monitors – a company will often release one monitor and never iterate with future updates and improvements. I also questioned, ‘Why?’ After all, I thought the first version of the Qingping Air Quality Monitor was quite great. I struggled to figure out why Qingping was rushing to update what I already considered a great air quality monitor.
Well, after using the Qingping Air Quality Monitor Generation 2 (which I will refer to simply as the Qingping Air Quality Monitor from here on out), I see why they chose to update the device. At the risk of spoiling my review, this device is fantastic. Even though the price has increased slightly, I think this new Qingping Air Quality Monitor is what many people are looking for.
Now, before I give away the whole review, let’s get started. We will begin by discussing the monitor’s accuracy and sensor tech. After discussing this, we will move on to other aspects, such as the design, connectivity, pricing, and competition. At the end of this review, I will also give the monitor an overall star rating. With that all out of the way, let’s dive in!

Differences Between Generation 1 and 2
Generation 1 (left). Generation 2 (right)
When I heard about the generation 2 Qingping Air Quality Monitor, the first question I asked was, ‘What are the differences?’ Since you’ve probably already asked that question, let’s explore those differences before discussing the monitor in more detail.
- The screen has been upgraded from 3.1 inches to 4 inches.
- The PM sensor is now designed to be replaceable.
- PM10 and noise measurements have been added.
- An alarm clock function has been included.
In addition, the generation 2 device also has a different VOC sensor (SGP30 vs SGP40) and CO2 sensor (now the Sensirion SCD40), but the other sensors remain the same between the two devices. Based on the performance of the previous device, this is not an issue. But let’s discuss that soon.
The most obvious difference is the screen size. While the two monitors look similar in the images, it’s hard to overstate how much of a difference the screen size upgrade makes. Further down the line, I can also imagine the replaceable PM sensor making a difference, but let’s see!
Before we move on, there are a few things to note here. Firstly, the addition of a noise sensor comes with some privacy questions. When I asked Qingping about this, I was told the device only measures the sound energy that the noise sensor detects and doesn’t record, store or upload the sound.
Secondly, the Qingping Air Quality Monitor generation 2 is slightly more expensive than the previous monitor. While you will need to check the exact pricing at the time of purchase to see the difference, I’ve found this new monitor typically costs about $20 more than the first generation. With the improvements, however, I would recommend opting for this newer version if you can afford it. With that said, the first version is still a fantastic monitor!
Accuracy & Sensors
The Qingping Air Quality Monitor Gen 2 uses the same PM2.5 sensor as the previous model, but the VOC sensor has been updated from the Sensirion SGP30 to the newer SGP40, and the CO2 sensor is now a Sensirion SCD40. This means the sensors are from the following brands:
- CO2 – Sensirion
- VOC – Sensirion
- PM2.5 & PM10 – GrandWay
While I’m not sure of the exact model of PM sensor used (I usually do a teardown, but I don’t want to do one until I get my hands on a second monitor), it’s been found to perform well in the previous generation device. Considering the similar design, I can’t see any reason this would be different.
Before we move on, I want to mention that while the Qingping Air Quality Monitor Gen 2 has ‘added’ PM10 readings, these are provided by the same sensor, and there is no additional sensor to include this functionality; Qingping has just decided to enable PM10 readings this time around. While this seems like an artificial limitation so that it could be a ‘new’ feature on the second version of the device, it’s worth noting that PM10 readings from low-cost sensors are often wildly inaccurate as the concentration is estimated based on PM2.5 concentrations.
With this in mind, I assume that Qingping disabled PM10 on its first-generation monitors due to the inherent flaws of measuring such particles with low-cost sensors. However, they may have received enough requests to enable measurements for this particle size now, even if they shouldn’t be relied upon.
A screenshot from AQMD’s AQ SPEC program. Notice the inaccuracy of PM10 from the different low-cost monitors.
Another caveat we should discuss before proceeding is how the VOC sensor performs. Current popular VOC sensors such as the Bosch BME688 (found in PurpleAir, for example) and the SGP40 (in AirGradient, as well as this monitor) use an index to show VOC values by default. While you can change the units to parts per billion or mg/m3 on the device, these approaches are imperfect for reasons discussed in much more detail here.
By default, the Qingping Air Quality Monitor will show VOC values between 0 and 500. What is somewhat confusing, and not limited to the Qingping device, but rather any device with the SGP40, is that this is an index, where 100 is the average 24-hour exposure and anything below 100 indicates decreasing VOC levels, while anything above indicates the opposite. This means that the VOC measurements shouldn’t be used as absolute values (even if you enable ppb as the units, for reasons mentioned in the linked article) but for identifying relative increases and decreases. To their credit, Qingping has been very transparent about this in the manual, and this isn’t an issue unique to its monitors.
Now, with the caveats out of the way, how does the monitor perform regarding the accuracy of other parameters? Well, as you know, I typically love to do my own testing in these reviews, but I’ve encountered so many problems over the past two weeks of my testing that I will instead refer to the AQMD results for this section. At first, I had wanted to compare it to some monitors that use SPS30 sensors, but after a week of data collection, I realised my comparison monitors had somehow disconnected from the WiFi and hadn’t uploaded anything. I then tried for a further week and ran into many other issues that made me give up on my comparison – at least for now.
The good news is that AQMD does some of the best and most trusted testing on the internet, so we can use its results for this section instead. While the generation 2 device has not yet been tested, the first-generation device correlated well with reference-grade PM2.5 monitors in real-world tests. While it performs a bit worse than monitors from PurpleAir, it also performs much better than more expensive monitors such as the AirVisual Pro.
I also referenced some graphs from SmartAir in my review of the first-generation monitor, which further shows that the Qingping Air Quality Monitor correlates well with reference-grade equipment but that it does tend to understand PM2.5 concentrations. Since the first monitor couldn’t measure PM10, there are no results for that, but I wouldn’t expect much, seeing as the Qingping Air Monitor Lite uses a sensor from the same brand and shows only a 0.37 – 0.43 R-squared value (1 indicates a perfect correlation).
As for carbon dioxide measurements, I expect this monitor to perform well as it houses a Sensirion SCD40 sensor – the same brand you will find inside many devices, such as the AirValent CO2 monitor. Luckily, I was able to record some CO2 data so I could share it!
In the graph above, I compared the carbon dioxide readings from the Qingping Air Quality Monitor to the Aranet4 Home, which is generally regarded as the most accurate consumer-grade CO2 monitor. As you can see, both devices read similarly, but there were some deviations. That said, these were within the stated accuracy of both devices.
These results are very similar to what I found during my review of the first Qingping Air Quality Monitor, and this leads me to believe the performance between the two is more or less identical – despite using a different sensor. However, considering that consumer-grade CO2 sensors are quite accurate these days, this makes sense. It is also worth noting that you can manually calibrate this sensor from the device, meaning it’s easy to set a new baseline when needed.
That brings us to the temperature and humidity sensor. While I don’t have something I can consider ‘reference-grade’ to compare to, Qingping has placed the temperature and humidity probe behind a separate vent that can be found away from the other sensors in the device. While I can’t speak to its accuracy, Qingping has clearly thought the placement through enough to place the probe away from temperature-generating components where possible.
Overall, the Qingping Air Quality Monitor Gen 2 is a solid performer regarding accuracy, both in my own testing (which has, admittedly, been messy and limited) and according to AQMD, the PM2.5 results are accurate and on the better end of consumer-grade air quality monitors. The CO2 readings are also accurate when compared to an Aranet4. While there are some caveats to the PM10 and VOC readings, these are consistent across all low-cost air quality monitors and are not an issue unique to this device.
Design
One of the aspects that makes the Qingping Air Quality Monitor have such a great user experience is the large, 4-inch touchscreen that dominates the front of the device. This significantly improved over the first generation, which sported a ‘mere’ 3.1-inch touchscreen. It’s this touchscreen that makes this indoor air quality monitor so unique. There are other air quality monitors with large screens, such as the IQAir AirVisual Pro, but very few monitors merge this large screen with touch capabilities.
Of course, a touchscreen alone isn’t particularly useful in many cases. However, Qingping has ensured that this touchscreen is a pleasure to use by ensuring it’s responsive and creating a complete UI built around the touch capabilities. Even if you’ve never used this monitor before, it’s intuitive to pick up and use, and I think anyone can navigate the UI, even with no prior experience.
An issue that many low-cost touchscreens encounter is a lack of responsiveness, but I can confidently say this isn’t the case here, as navigating the UI on the Qingping Air Quality Monitor is a breeze, and the monitor is very responsive. While you might notice a few dropped frames occasionally, it’s never had a significant hiccup over the three weeks I’ve used it.
In addition, the screen is high-resolution with a pixel density of 254 ppi. If you’re unsure what this means, it essentially means that there are 254 pixels for every inch of screen – while significantly lower than many modern smartphones that sit at 400 ppi and above, this is fantastic for a low-cost monitor, and the screen looks beautiful. It also appears to have much better viewing angles than the first-generation device, making it easier to see the screen at an angle.
The touchscreen is a pleasure to use, and I wanted to focus on this aspect of the Qingping Air Quality Monitor first, as it’s what you will spend most of your time interacting with and looking at. This screen also makes the monitor fantastic as a standalone device. While it does feature good connectivity, there’s no need to pair this monitor with your phone if you don’t want to, as everything can be done on the device itself – even connecting to WiFi!
Other than the screen, there are a few other features on the front. Above the touchscreen is a light sensor, which can be somewhat misleading as it looks like a camera (but thankfully, it is not). This sensor adjusts the screen brightness when automatic brightness is enabled. Below the touchscreen is a small, horizontal vent that allows air to enter the device and be measured.
Turning the device around, you can see its interesting form factor. While the front of the device makes it look rather large, as soon as you turn it around, you can see that it is the shape of a capital L (or a reversed capital L if you turn the device around the opposite way!). At the bottom of the L is the chamber that houses the sensors, mainboard, and a small battery. Despite being an interesting shape, I’ve come to like this form factor, and it looks nice on a bedside table, desk, or otherwise.
That brings us to the back of the device – normally an uninteresting part, but something that is a highlight with the updated Qingping Air Quality Monitor. Why? Well, similar to smartphones of old, the Qingping Air Quality Monitor Generation 2 has a removable backplate that hides the removable and replaceable PM sensor module. You may be wondering why they chose to make only the PM sensor user-replaceable, but it makes some sense as these modules tend to have the lowest lifespan due to their reliance on moving parts – in this case, a fan.
I assume Qingping had some issues with failing PM sensors on their previous model, which is why they made this significant change. However, I’m all for it. Being able to replace the sensor that is most likely to fail is a huge step in the right direction, which, in this case, is user repairability and increasing the lifespan of devices. Maybe I’m asking too much, but imagine a version three device with a user-replaceable battery or CO2 sensor in the bottom slot. I’m just throwing around some ideas, but wouldn’t that be cool?
Either way, I love this change, and Qingping has made it exceptionally easy to replace the PM sensor. However, since it’s housed in a proprietary housing, you will need to purchase the replacement module from Qingping – you can’t just buy an off-the-shelf sensor as a replacement. I’ve been told the replacements will sell for $25.
Overall, the design of this product is yet another strength and it’s a very pleasant device to look at. Before concluding this section, it is worth mentioning that you can purchase a white monitor if you prefer. I opted for black as I wanted a device that stands out against my white walls, but I’m sure many people will prefer the white design.
Before moving on to the next section, it’s also important to note the Qingping Air Quality Monitor has an internal battery. While the monitor’s design clearly shows that it isn’t intended to be a portable air quality monitor, having an internal battery means you can move the device around your house to test the air quality of different rooms without needing a power source. While the battery life is only a few hours, it’s also long enough to keep the device powered through power outages, which I appreciate (they’re quite frequent here!).
Typically, I also discuss the user interface in this section. However, since it’s such an essential and prominent part of the Qingping Air Quality Monitor experience, I felt it would be best to dedicate a section to it. If you want to learn how intuitive the device is, read on!
User Interface
As I mentioned above, I typically wouldn’t cover the user interface in a dedicated section, but I think this device needs this section for two reasons: first, it’s very well thought out and has received a lot of attention. Second, anyone wanting to use this device without the accompanying smartphone app will rely purely on this UI, so it’s worth discussing.
The device’s home screen will change to a screen saver after a few minutes. The user can set this screen saver, and it can be customised in an almost identical way to an Apple Watch. The time will feature prominently, but you can edit every other widget on the screen and the order in which the pollutants are displayed. This is a fantastic approach and lets the user set only the information they care about the show on the home screen. You can choose from three layouts, mainly focusing on whether you want to show an analogue or digital clock.
As soon as you ‘wake’ the screen by touching it, you will be met with a screen like the one in the image above. Tapping on any individual pollutant or environmental parameter will move it to the prominent position at the top. From here, you can tap the graph icon in the top right (again, shown in the image above) to see a detailed graph of your indoor air conditions over the past 24 hours or 30 days.
While you can see some information on this screen, and it’s great for a quick overview, you will want to export data via the app for a full breakdown. That said, I’m glad you can see some historical data on the monitor itself, even if it is limited. One aspect that I really appreciate about this device, however, is that you can tap on the information ‘i’ to learn more about the pollutants and the thresholds.
For anyone who is already aware of the intricacies of indoor air pollution, you won’t find yourself tapping on this information button very frequently. However, these snippets of information make this monitor so much more accessible for anyone who is using an indoor air quality monitor for the first time.
For example, tapping the information button for PM2.5 will raise the thresholds and allow you to switch between the U.S. EPA PM2.5 standard and the China Standard. There is also a short description of the dangers of PM2.5 and common sources of this fine particle pollution. Overall, this is an excellent user experience, and I think it makes this monitor perfect for first-time users.
Unfortunately, for some things, such as carbon dioxide, the thresholds are based on the relatively lenient China Standard GB/T 18883-2002 (which is helpfully mentioned on the device). I wish there were another option for CO2, similar to how you can change standards for PM readings, but I also don’t think this is too big of an issue for two reasons – firstly, you can read the absolute concentration in parts per million easily, and you can set up entirely customisable alarm thresholds for every pollutant – but more on that soon.
While I don’t agree with all of the standards, I love how Qingping has been completely transparent about which standards they are using to base the thresholds on. Every air quality monitor should be like this, and I appreciate how they go even deeper to explain to everyone the dangers and sources of every pollutant. Let’s move on to a few other features that make the Qingping Air Quality Monitor unique!
If you swipe left from the home screen, you will get to a weather station screen which shows the time, weather forecast (when connected to the internet), and local AQI and UV index. To view more information about the weather forecast, you can tap on the block and be led to the screen shown in the image below. This shows how Qingping has tried to make this device an indoor air quality monitor and a weather station for your home – they’ve certainly done a better job than some manufacturers, too!
It is worth noting that you might not get all of this information if you live in a smaller town or city. For example, when I was in a small town in the Philippines, I couldn’t view AQI or weather information as there were no monitors in whatever network Qingping was relying on for this information. However, in a larger city such as Davao, I can get all of the information I need on this screen.
Swiping left once more will bring you to the settings screen. This screen has four buttons which allow you to set an alarm (yes! This monitor also acts as an alarm clock, which the first version did not), change device volume (pollutant alarms and the alarm clock volume can be adjusted separately), change screen brightness, and delve into the complete device settings which are partially shown below.
You can adjust the device’s settings from this screen without relying on the accompanying app. I absolutely love being able to do this, and you can even perform advanced functions such as calibrations here on the device. While there is much to talk about here, I want to focus on a few particular aspects.
Firstly, the over-limit alert settings will allow you to set alerts for every parameter this device measures. That means you can set alarms for everything from PM2.5 concentration to noise levels. The best part? You can manually set the exact thresholds and even adjust if the alarm is a minimum or maximum threshold. Why can’t more companies introduce this completely customisable alarm functionality? It’s fantastic.
Secondly, you can update the device from this screen. This is worth noting because a community member found some bugs with the device and reported them, and the Qingping team fixed them within two weeks. Based on this, the support of this device again appears to be fantastic, and there may be more updates to come down the line.
Overall, the Qingping Air Quality Monitor Generation 2’s UI is fantastic and feels much improved over the first generation (which I still liked). I know this section may seem overly positive, but I really appreciate this device’s UI and overall user experience. Besides a few questionable standards, there is so much to like here, and I think this might be the best monitor to recommend for new users.
App & Connectivity
While the Qingping Air Quality Monitor Gen 2 is a great standalone device – and perhaps the best standalone air quality monitor I’ve tested to date – it also has connectivity. It works with one of two apps: the home-focused Qingping+ app or the team-based Qingping IoT app. While having two apps is somewhat confusing, I’ve been told that the Qingping+ app is for most users, whereas the Qingping IoT app is better suited when you have a team that needs to view data (such as in an office building).
To add the monitor to either of these apps, you must first download one and then add a monitor. From here, go to your device and select your chosen app from the settings menu. This will give you a code to enter in the app to connect. The process is super straightforward, and I’ve never had any issues with this onboarding process despite having four separate Qingping monitors. Of course, you must first ensure the monitor is connected to WiFi.
Above are some screenshots from the Qingping+ app. One of my pet peeves with these kinds of apps is that they often require you to log in. While Qingping does try to make you log in, you can skip this process and use the app without any account. I am a fan of this approach, and I hope it will stay so in the future.
From the app’s home screen, you can see the data from your connected Qingping monitors and some suggested actions. Tapping on a monitor will take you to a more detailed screen that breaks down all measurements and provides a historical graph. While the graph in the app is limited, there is an option to export data, which is much better for anyone who wants to break down their air quality trends. Unfortunately, exported data can only be shown in 15-minute increments, so I hope this is adjusted in the future.
What surprised me the most about this app is its few settings. Sure, it makes sense since everything can be done on the monitor, but you can’t do much other than export data and change units in the app. For example, you can’t calibrate CO2 from here (which would be nice, as I like to leave my monitor near a window and trigger a calibration that way).
Is this a big deal? Probably not, considering the settings are there – they’re just housed on the monitor instead of in the app. That said, I would love to have duplicates of all settings in the app for the sake of simplicity and convenience. After all, sometimes I don’t want to get up to change monitor settings.
Overall, the Qinping+ app is fast and straightforward to use, and I have no qualms with it. However, it does feel very simple and almost lacking. Of course, you can change all of the needed settings on the device itself, but I can’t help but feel like it would be nice to also have these options in the app. Thankfully, this doesn’t impact the device’s usability much, as everything is there, just not on the app.
Moving onto the Qingping IoT app, we find a very similar-looking interface with the same simple, clean, and easy-to-understand layout. However, it also suffers from a lack of settings. This app’s biggest benefit is adding multiple team members to view data from the monitors on their own devices. While I haven’t seen a need for this yet (especially as the monitor has a screen, which ensures everyone can view it), I imagine this would be ideal in offices, classrooms, or even houses with many residents.
I don’t feel like there is much point in delving too much deeper into the Qingping IoT app because, for one, there isn’t much to it, and second, the features are almost identical to the Qingping+ app. I love how easy both apps are to use and how they convey information, but I would like more advanced settings (such as the ability to set temperature and RH offsets). At least that ability to export data is there!
Pricing & Competition
The Qingping Air Quality Monitor Gen 2 sells for around $150, costing around $20 more than the original monitor. At this price range, it’s comfortably in what I would call the ‘mid-range’ or air quality monitors. There are much cheaper options out there, such as the Amazon Smart Air Quality Monitor, IKEA’s monitors, or even the Qingping Air Monitor Lite, but there are also far more expensive monitors, such as the Airthings View Plus. Below is a table with a few other popular monitors that people often consider alongside the Qingping Air Quality Monitor:
| Monitor | Price | Pollutant Sensors |
|---|---|---|
| QP Air Monitor (Gen 2) | $149 | PM2.5, PM10, CO2, tVOC |
| QP Air Monitor (Gen 1) | $129 | PM2.5, CO2, tVOC |
| QP Air Monitor Lite | $99 | PM2.5, PM10, CO2 |
| uHoo | $399 | PM2.5, PM10, CO2, CO, tVOC, NO2, Ozone |
| AirVisual | $295 | PM1, PM2.5, PM10, CO2 |
| Awair Element | $299 | PM2.5, CO2, tVOC |
| Wave Plus | $299 | CO2, tVOC, Radon |
| AirGradient ONE | $138 – $195 | PM2.5, PM10, CO2, tVOC, NOx |
Of course, most of these monitors are far more expensive, and I think the most direct competition in this price range is the AirGradient ONE (the DIY kit costs $138). Now, I do want to make the disclaimer that I now work with AirGradient, but they’re fully committed to transparency, and I am able to speak my mind – and even encouraged to!
While the AirGradient ONE and Qingping Air Quality Monitor are similar in price, that’s where the differences end. If you want a customisable, open-source air quality monitor backed by a team of scientists, the AirGradient ONE is a great option. However, nothing comes close to the user-friendliness and accessibility of the Qingping Air Quality Monitor – especially as performance is roughly the same. It really comes down to how much of a ‘power user’ you are.
If you want to be able to export data in different time intervals, be able to have the option to change all components (not just the PM sensor) and be able to integrate with platforms like Home Assistant, the AirGradient monitor is a better choice at this price point. On the other hand, if you want a fantastic monitor that provides a much more hand-holding experience while also acting as a great standalone device, the Qingping is the way to go. For my recommendation, I think Qingping is undeniably better for people getting involved in air quality monitoring for the first time. However, it lacks some more advanced options that ‘power users’ might want.
Conclusion
If you’ve read this review through completely, I’m sure it probably comes across as overly positive. However, I can promise that this article has not been sponsored, and I am genuinely excited about this monitor. When I reviewed the IKEA Vindstyrka and Amazon Smart Air Quality Monitor, I was excited because they have the power to make indoor air quality monitoring more accessible by lowering the prices of such monitors.
However, Qingping does the same, but through a different method. While it’s much more expensive than either of the monitors mentioned above, it’s capable of making air quality monitoring more accessible by being easy to use and holding the hands of new users. If I were to recommend a monitor to someone without experience with air quality monitoring, I think this is now my go-to. Why? Because it provides explanations and details on-device about everything. This removes a significant knowledge barrier and details why each metric is important to monitor. It even goes as far as to detail common pollutant sources for each parameter.
As with any air quality monitor to date, it isn’t perfect. I think the app functionality is somewhat lacking, and I would like to see an update with stricter CO2 thresholds (or let the user set them) and user-adjustable offsets. With that said, this monitor really excels at being easy to use while still providing some advanced functionality, such as the ability to set alarms based on any value you want and the ability to export data (albeit in 15-minute intervals). I haven’t yet seen the former option on many air quality monitors.
Qingping has quite a unique value proposition here, and I don’t think there is any direct competition in this price range. Of course, there are similarly priced air quality monitors with potentially better components, like the AirGradient ONE. Still, they don’t compete directly because they have completely different use cases due to the large touchscreen and standalone functionality of the Qingping Air Quality Monitor Gen 2.
The biggest question you must ask yourself is this: Do I need the more expensive generation 2 model, or will generation 1 suffice at its cheaper price point? They share nearly all of the same strengths, but at around $20 more (likely more in the future as the generation 1 price drops), are the extra features like the alarm clock and bigger screen worth it? I definitely wouldn’t upgrade from generation 1 to this, but if you’re buying Qingping Air Quality Monitor for the first time (or purchasing a second or third monitor), version 2 is very tempting. At the end of the day, they’re both great devices.
