Customer Ratings & Reviews

I purchased uHoo - Smart Indoor Air Quality Monitor to analyze the air quality both in my office and at home. Suffice it to say, I am both pleased and dismayed by the results!

Very upset! I recently found out that this monitor is not providing correct readings. 2 of the readings started to show the highest level at all times. I contacted uHoo and they “remotely recalibrated” it. Now the readings are around zero which I know is incorrect due to several other monitors. Very disappointed that I counted on this expensive machine and it was wrong.

Other sensors I have in my home don’t correspond with this device - not sure if I trust the data produced. Even the thermometer is off greater than 5°F! Item feels cheap and zero information about the sensors.

This is a neat little device that monitors the air quality of the room that it's in. It's aesthetically pleasing and does not stick out like a sore thumb. The smart app that is used in combination with this device makes monitoring and checking on the air quality statistics very easy. One of the best part about this device is how easy the setup was. All that was needed was to follow the step-by-step guide provided by the application and you are up and running within 5 minutes. The application itself has a helpful guide that shows you what every statistic means. It is up to you, the user, which statistic matters to you. Personally, I was most interested in the amount of particles in the air. While the application is great in many aspects, it is also disappointing in some. Once such case is that there is no way to set alerts when measurements hit a certain level. You can only turn on or off alerts that doesn't tell you when it will alert you. The help page is also a little wonky, in that some of the bars do not display correctly so you do not get the full picture. I also wish you could customize the graphs a bit more, like being able to set a time period for the charts instead of being limited to hour, day, and month. Since this device is so heavily dependent on the application, they should put more usable features on it. Overall, the device itself is great but the application is a little lacking.

Recently and almost on schedule lately my area has been in the middle of terrible fires. I live in Northern Bay Area California and for the last few summers (this one being no exception) we have had multiple large scale fires. So much so that we currently have family here that had to evacuate their house. And despite the sky being shockingly beautiful around sunset with a red looking sun the air is terrible. So its great to have a device that not only lets us know what are air quality is, but gives recommendation on how to improve it, although opening a window in this situation isnt the best idea. The device itself has a very nice build quality and fits right in with most settings. Set up was fairly easy, but it does take awhile to calibrate. Now there might be people that think this device somehow can detect Covid and that just isnt the case. But with Covid being everywhere now it does cause most of us to be home a lot more often than normal, even more so with us due to the fires. Were in a no win situation currently. Cant go out and do things due to the virus, and risk lung and respiratory issues from the air. So having a way to detect what the air quality is in our house where you will be spending 95% of your time at is nice. Overall I would say this device is a piece of mind giver. Its one of those devices you hope you dont need like a fire alarm, but when you do have it it can be a life saver. Getting notifications of a change of, or an alert for some toxin, etc can literally save your life. So its definitely a worthwhile addition to the house. Hopefully these fires cease soon, but in the meantime its nice to know the air in the house is being monitored just in case it gets worse before it gets better.

The uHoo air monitor is an exceptional option for anyone looking to get a visualization on their indoor air situation over time. The only real decision here is whether the peace of mind is worth the cost of admission. There really isn't much to this thing. It's a small-ish, unassuming tower that does its job silently in the background, relaying all information to the app. The app does a decent job of displaying the wealth of information the uHoo has stats for, including: temp, humidity, air pressure, CO2, TVOC, PM2.5, CO, NO2, and Ozone. It's an exhaustive list of measurements that's tracked over time on a series of bar graphs. The UI isn't necessarily the most polished thing I've seen, but it does an adequate job of showing the information at hand. They've included some helper text to inform users on each of the aforementioned values being tracked, a nice touch which helps to understand what the various PPM values really mean. Finally, they also list a "Virus Index." This seems to be a calculation based on air pressure, humidity, and other related measurements to determine how likely it is for viruses to survive in your indoor space. One thing I've noticed while playing around with the app is that it offers quite a surprising amount of customization. You can display the UI in list or grid view, you can set alerts, you can adjust the thresholds for each measurement, etc. It's a nice touch to help fit a wide number of usage scenarios. I left mine at the defaults with the assumption that they're a good marker for the average user. My only negative in dealing with the uHoo was the setup process. It's admittedly convoluted; you download the app, plug the device, connect to the device's Wifi (which obviously has no internet connection, which may trip some phones up; make sure you select any "Stay connected anyways" options that may arise on your phone), and theoretically let the thing do its setup job. This didn't work the first time, though, and it took repeated resets to get things to finally work. Other gadgets have devised more pain-free ways of doing this (using bluetooth for the initial connection, for instance), and it's the one area I could see an improvement warranted. Otherwise, this gadget does exactly what it says it's going to do. You already know if you want or need this device, and if you're like me (a parent who went into full on paranoia mode and got this for my newborn's nursery), you'll enjoy the peace of mind that comes with being able to track your indoor air quality over time, albeit at a cost.

The uHoo is a "smart" indoor air quality monitoring sensor. It covers 9 different things (temperature, humidity, air pressure, CO, CO2, Ozone, NO2, VOCs, and PM2.5). That last one is essentially just dust and about the only questionable measurement it gives. What makes it smart is that there's an app that goes along with it which can give you alerts for different types of scenarios using a combination of measurements of those nine quantities. In the context of COVID-19 and recent fires in the area, this kind of device can be useful but the ecosystem around turning that data into useful action is not really there. The uHoo package is pretty simple. The monitor, usb cable, and power adapter. You set up the device in one room, I'd recommend a family room or other main room in the house that gets decent usage, download the app and use it to configure the uHoo (pairing it to your wifi), and then you're off to the races checking out air quality and getting alerts. You get a colored (red, yellow, green) view of the quality of the 9 different monitors but you can also look at the actual numeric level that was measured. Some measurements aren't truly ready immediately, so plan on having this sit for a couple days before relying on all the monitors. I'm not sure what that means if you take it traveling - does it need another 2 days of warm up or is it just a first time thing? I don't have a good way to verify the numeric values reported by the uHoo. Qualitatively, I can verify a few monitors did change in response to environmental conditions. We've had fires in the area, about 3-4 hours away but waves of smoke which blanket the city. Enough that it's become a regular thing to come out in the morning to a car coated in a fine mist of ash. The uHoo definitely saw the change in CO and CO2 and NO2 emissions. On a day where the city was issuing ozone warnings, the uHoo did have it's ozone monitor go into the yellow at home. The PM2.5 has always been in the green - I suspeect it would work but the uHoo is designed as an indoor sensor and my own response, based on what I can see and smell is to close my windows when there's obviously poor air quality. So, while the uHoo does report things and seemingly it is responsive and likely accurate, on it's own, at the level that I'd notice the poor air quality myself, there's no beenfit over having yet another notification telling me something I either already know or would know from the radio, digital billboards, or other announcements in my normal day. So, it seems the big utility for this is in its integration wiht other services, IFTTT, Google assistant, and Alexa to name a few. If there was a recommended action that I could take with this in conjunction with my HVAC or some other device, perhaps an air purifier. However, aside from acting as another temperature sensor input to the HVAC, I don't really see this as a useful data source for my home automation. And my other devices already bundle environmental data from other sources in the area that I'm not sure I get much benefit from having the uHoo locally. I can see this being more usefull if there was a system in place to automatically close windows, purify air and take some action to combat bad air quality but at best, it seems it can serve as a warning that something is wrong when you're away from home for an extended period of time. The uHoo does a good job of monitoring and reports measurements in an easy to understand interface. But that's where things currently end. Without a way to make good use of this information, it's at the level of a home weather station - just duplicates information you likely already see when you glance at your phone or smart thermostat.

Overall the uHoo device is an interesting mix of sensors for monitoring air quality in a room, what I'm unsure with the device is the calibration of the sensors. For things like particles in the air or even CO2, I don't have anything else to compare it with, so the measurements it provides me I take with a grain of salt only because I can't verify the readings. That was my biggest problem, I just don't know off hand how accurate within a reasonable range they. I didn't see anything so out of whack that I doubt it, I just wonder how best to verify the data. That said let's get onto setup with the uHoo. That was very well done. I was using the Android version, but unlike a lot of other IoT devices this walked you through setup and it was easy without an issue and the device came online first try no needing to figure out how to reset it and try again. It just worked, that was very nice. Once that is done, you just leave the device in whatever room you want to monitor. I'd recommend at least for the first week you turn off the alerts in the app since a few of the sensors took a few days to calibrate according to the app, like the volatile compounds. Once its dialed in you can adjust the alert thresholds and monitor the air quality. I do appreciate the app allows me to set alert levels, since you can customize your thresholds. Now the app does take this information from all the sensors and gives you a score from 1-10 on the ability of viruses to live in that area. Interesting information and that is all it is. Nothing something that will prevent them. Just gives you an idea of what you might want to adjust. The overall sensor package is small, and looks ok and can fit anywhere where it can get power and Wi-Fi. This can be handy to monitor spaces for dust or should I open a window, or what the temperature is. The graphs in the apps are nice and a handy way to track trends for the month. Overall if you are looking for a sensor package to monitor the diverse things this covers from CO/CO2/Volatile Compounds/Temperature/Humidity/Air Pressure/Dust/Ozone/NO2 this might be something you can use.

This indoor air quality monitor exceeded all my expectations. And at the end of my review period, it has become particularly essential. Measuring indoor air quality as it deteriorates with all the smoke from the fires here on the west coast. So, I'll start with that. As the outside air has been mostly on the hazardous scale since Labor Day with the monitor showing slowly increasing dust in the air and buildup of carbon dioxide most noticeably. This is because we are unwilling to exchange more air from the outside, so carbon dioxide is not getting diluted as much with fresh air. I think the dust reading is just from the finer particles that are getting in when doors are opened. We have made several more air cleaners by putting furnace filters on box fans to go along with some of our more fancier air filter systems. After we did that we watched as the uHoo showed lowering dust/fine particle levels in the air. This has helped us to quantify what is going on with the air that is getting inside from the wildfires and help us see how our attempts to keep the air quality as good as we can have been doing. So, now the main review. The Uhoo helps you see trends about things you can't readily observe. Setup was very easy and through the smartphone app, which you must use. Upon setup being completed, the app shows how long till the various sensors will be done with calibration. The longest takes 2 days, and that is the Carbon Dioxide sensor. The uHoo should be left in the same place for this initial 2-day period. So, I set it up in a large bedroom that has good airflow during the day and slightly less airflow at night when the door is closed. All the readings were good and well in the green except for the Carbon Dioxide readings which were in the red. The default settings are pretty good for the levels, and there are Green for Good, Yellow for Borderline, and Red for Concerning. You can set alerts for different levels to keep you updated. After two days and initial calibration was completed, I moved the sensor around the house every couple of days and the Carbon Dioxide levels were about the same throughout the house, but the highest in the large unfinished room in the basement where the furnace is. It was a bit higher there, and that room does not have any central air duct outlets in it, just the huge furnace stack and fan. We left the uHoo in that room for monitoring, since it had the worst air quality in the house. You can buy more units if you want multiple rooms monitored at once, but that will get very expensive very fast. The app shows data from all the sensors. You can see the trends by the current hour, by the current day, or the month. You can easily swipe to the left when seeing the current hour for instance, to see the full data chart form the previous hour, works the same with the day chart, and I assume with the month chart. This led me to airing out the house, and with box fans to pull in fresh night air upstairs and push out air downstairs in the mudroom exit, the carbon dioxide levels would drop well into the green after about 20 minutes. And then when we shut the house back up for overnight, they would slowly creep up back into the red, mid 1500s or even a bit higher. The uHoo helped me realize something I had completely overlooked about our big old house. It was built in 1960 and we have lived in it about 5 years now. What I didn't realize is that it does NOT have an air exchanger built into the Central Air system. I was so use to ones on timers or otherwise set and forget at my previous houses, that I didn't even think about it. Well, we have made the house a lot tighter as far as energy efficiency since we moved in, so we are keeping the same air longer, and carbon dioxide builds up from all the people and I learned from all the plants at night when photo synthesis is not happening. Since we have started airing out the house, complaints of headaches and random fatigue have gone down noticeably. You really need to keep on top of air quality when a lot of people are stuck in the house, either due to quarantine or the really bad outside air this September from the fires. The uHoo has helped tremendously with these issues and I wholeheartedly recommend this to give your family a sense of how things are trending with the Air quality in your home.

It is challenging to write a review for a product like this without having a laboratory to backup the data. However, the sensor seems to be accurate. Once connected to WiFi and the phone app, the data is easily accessible and sortable by hour, day, or month. From there, the app explains what each reading is, why it is important to measure, and how to improve that component of the air quality if it is bad ie open the windows, turn on air purifiers, get a humidifier or dehumidifier. This is extremely beneficial for someone like me who suffers from severe environmental allergies along with some asthma. The better the air quality, the easier it is for me to breathe. In the two weeks the sensor has been running, it has not proactively alerted me to any dangers, but I have air purifiers running nonstop. According to the sensor, they are working well. Via IFTTT, I can have the sensor control my purifiers based on need instead of running continuously. And, I have it linked to Alexa to be able to ask random questions like air quality, temperature, humidity. Overall, this device can be a valuable tool for someone who is extremely sensitive to air quality. I really love how detailed the app is when it comes to descriptions and solutions. While I have a science background, I think it is written well enough that anyone should be able to understand it. Hopefully it will help a lot of people out when they are not sure how to fix the air problems at home.

Easy to setup, not so easy to get connected to to Google Home. I tried a few times but it just didn't work. It gives good amounts of data, but to what end? Most of the problems it detects there is nothing I can do about....Above avg CO2??? Guess I should just stop exhaling? They recommend I open a window, but the other alerts are that my higher room temperature of 76'F is causing higher humidity which would not be helped at all by an open window in North Carolina. Overall I think it's interesting data, but nothing highly actionable. I think this would be far more useful in a business than here in my home. I wouldn't recommend the purchase at this price point. Someone will do this cheaper at some point.

We purchased the uHoo Smart Indoor Air Quality Monitor due to concerns related to air quality in our house. Issues with moisture/drainage in our neighborhood and the discovery of furnace problems that could have caused CO issues (our stand alone CO detector never indicated a problem) led us in search of more in-depth, ongoing readings of our home air quality, especially in our basement workspace. The uHoo provides us with that detail and piece of mind. Setup was easy. Download the app, sign up for an account. Then power on the uHoo (power supply and cables included) and follow the app to connect discovered uHoo devices to your wifi (2.4Ghz only, I believe). The only part of this process that could be confusing to some is that in order to connect your uHoo to your home network, you briefly have to disconnect your phone/tablet from the home network and connect directly to the "factory wifi network" emitted by the uHoo. If you follow the (well written and illustrated) instructions and know how to use your phone, you will be fine. It would appear, however, that moving the device to a new wifi network will involve essentially a factory reset to the device itself. That could make it difficult to use if you want to travel with it. Once functioning, you will see statistics for your room. We have tested in two different parts of the house and saw numbers change (slightly) so we can safely assume it is working. (No CO, thank goodness.) As a side note, the device does not make any noise and any indicator lights that appeared during setup go dark after a few seconds so you don't have to worry about the uHoo blinking or glowing 24/7. The app readings are very clear and color coded to alert you to "danger zones" (green for ok, yellow for "not ideal" and red for "danger"). There are bar charts showing trends over time. The "virus index" is a composite reading that gives you both readings and tips to help "clean your air." The other 9 sensors (temp, humidity, air pressure, CO2, TVOC, pollution, CO, NO2 and ozone) are scientific readings. It is important to know that this device does not purify air. Nonetheless, it gives you good readings about the quality of the air in your home. I wish there was a "mold" or "allergens" component but at least we can get humidity under control and have a backup tool for reading CO levels, should they ever be a problem. CO2 is always high in our house (perhaps because of extended summer a/c use) but other than that, we were "relieved" to see that our air quality in multiple rooms has been good on the whole. This is a good device for anyone with medical/breathing issues, an "alarmist," or anyone who has the need or desire to keep tabs on room air quality via a remote app. I could see applications for this in areas such as a wine cellar, home brewing room, basement or attic office, garage, or other confined space where air quality/temp could pose a risk to an individual or product. Because I do not have any smart HVAC applications to tie the uHoo to, I did not try IFTTT or Google Assistant. Nonetheless, I can see how this device could be used (with IFTTT) to do things like automatically turn on a smart ventilation fan or turn on/off a smart (de)humidifier to further help maintain good air quality.

Although I'm still trying to understand what each unit measurement means to overall air quality, those which I've been able to understand and follow have been very helpful. This journey began with me waking up with dry, sometimes bloody, nostrils several weeks throughout the year. I assumed it was a lack of humidity so I bought a humidifier, which helped, but then my wife started to smell mildew in the mornings. Turns out the humidifier may have been working too well. In comes this wonderful little gadget. Over the past few weeks, we have had several weather swings in California each bringing their own unique set of air modifications. Now, I don't allow the alerts from the uHoo to drive me nuts, but they do guide me in small things I can do to improve current air quality. For example, I was cooking indoors on a very hot afternoon. I received an alert that my CO2 levels were getting pretty high, my temperature was getting high, my humidity was low and my virus index(likelihood of viruses spreading) was fairly high. Solution: open windows and/or adjust thermostat and use a humidifier. Trying to save energy on the AC, we opened the windows and turned on a fan in the kitchen, and ran the humidifier in the bedroom for a bit. Lo and behold all factors dropped after a while, given instantaneous results and satisfaction. Going back to my initial example, it even lets me know when humidity may be too high, thus increasing mildew growth, which triggered my wife's nose. A few simple adjustments, and we both are happy campers until the next warning. The app is fairly intuitive with plenty of explanations of what each measurement entails. I have all alerts on, but you can easily modify frequency and/or specific measurements. During the fire season, we are keeping a close eye on several measurements due to the irritants that come with air quality changes due to burning. Overall, I am very satisfied with this device. It makes no sounds, has no distracting lights and very little maintenance. You just set it up and forget that it is there. Definitely recommend if you want to keep an eye on air quality for allergens or any other harmful irritants that may be in the air.

It's pretty amazing the amount of insights this little unit gives you. I love the detail + the recommendations on how to improve your air quality. One thing I constantly get reminded to do is open my windows when CO2 levels get too high. I'm not an expert, but I did cross-ref this with a LEED engineer I know and he confirmed the levels and recommendations for me. With the current state of the world, I also greatly appreciate their "virus index" which tells you, based on the combination of factors in your air quality, how likely viruses are to survive for any long period of time in your home - very useful! The app is pretty, but the navigation can be a bit frustrating; just a minor nit, though, IMO. I'd love to see the unit extendable with "satellites" you could place around your house, though, because it's hard to find the "perfect" place to put something about as big as a 16oz aluminum can of soda.

If you don't know already, you set this unit up in a place where you'd like to check air quality based on 9 (10 if you count the Virus index) different metrics. The system tracks each metric on a periodic basis, and keeps that data over time which you can review via line charts. Each metric also gives you an idea if you're in the green/yellow, or red for each (because the numbers won't mean anything to most people). It will give you an explanation for yellow or red, to give you some idea of what you should do to mitigate the issue. The device will also send a notification via the app when a metric changes to yellow or red. Setup of the device and related app was simple on my iPhone. It took about 3 days for all calibrations to be be completed once I had the unit in place. I've placed mine in the basement, as this has become my 'work from home' area as well as where one of the kids sleeps. One metric which didn't surprise me too much was CO2 levels - which the device said were high. It said I should increase air flow in the area. Well we normally don't open windows down there but I decided to see if it actually changed, and it certainly did. Levels went into the green state the first day the windows were opened. There are a couple of things I'd like to see for this device: -Forcing it to be powered via wall jack seems like a miss. I didn't necessarily get to place it where I wanted to, simply so I didn't string an electrical cord to it. I don't know how much juice this thing actually uses, but it SEEMS like it isn't much and maybe could run on a rechargeable battery. -On a related note, I don't now what happens if the device loses power. I assume it will have to re-calibrate as if I had moved it. Why no battery backup? -Maybe there's a reason I'm not aware of, but it seems like Radon would be the perfect addition to the device if feasible.

I live in the Midwest where the air quality is generally good. I was interested to see how our in-home air quality is. The uHoo air quality monitor is a very interesting device. The app download and setup process was simple and I was able to read information within minutes. It takes up to 48 hours to calibrate the readings for air quality once the device is set up. During the first week of operation we had very hot and humid weather so the device was reading “conditioned” air. When the heat wave passed, we saw a noticiable difference in the reading once the windows were open. As it turns out, there were fires burning in the western states and we were getting smoke coming through our area from fires that were over 1,000 miles away. When the smoke layers blew through our state, the readings for air quality improved. Our takeaway was that it’s good to have a device that can monitor our air quality. We’re still learning some of the meanings of many of the metrics the device measures but we’re glad we have this device in our home.

Bought it to monitor indoor air quality. Not fully satisfied. Leaves a lot to be desired. Has a few bugs that need to be fixed.

getting it set up can be kinda awkward, but it gives some great information. We had a humidity problem and it allows us the track when the numbers were too high.

The PM 2.5 and TVOC readings are completely inaccurate. For example, my unit was measuring TVOC levels rising rapidly into the hundreds, at which point it reboot itself and started showing levels close to zero. Regarding PM 2.5, the readings are noisy -- ranging from 2 to 10 ug/m^3 from one minute to the next (with no change in conditions). They also are inaccurate compared to several IQair AirVisual monitors and a Dylos. Note that uHoo is rated poorly by government studies [http://www.aqmd.gov/aq-spec/product/uhoo].

Do not buy!! Product does not work, will not connect to internet. Apps have low ratings, understandably because they will not connect to monitor. Customer service is poor. Will not allow refunds even though product does not work
