Expert Reviews


What reviewers liked

You can go into the app to pick up these readings, or you can have alerts sent to you when reading go outside of thresholds that you've set. Most of the time, during the day, with a window open I have a consistent set of green — all levels were fine. But in the evenings, things would shift — particularly one night where we cooked and baked for the holidays, and I saw carbon dioxide level raise substantially. Opening a window? That helped within minutes. You can also see when readings are fair, with the details turning to a mustard colors, and poor, when numbers are displayed in red.
Its biggest highlight stands in the integration capabilities it boasts as you can pair it with smart thermostats, automatic air purifiers, and other IFTTT devices. It even works with Alexa, so you can conveniently learn how healthy your home’s air is at any moment. Furthermore, the manufacturing company backs it against defects for 1 year after you make the acquisition.
Integrating Alexa with a smart indoor air quality sensor like uHoo can make the sensor even more useful and valuable in taking care of your family’s health. Aside from showing a real-time report on the app, uHoo also gives you useful tips on how to properly manage your indoor air quality. Furthermore, it can also be connected with other smart home devices inside your home through IFTTT.
The UHOO is perhaps the most technologically superior and detail oriented air quality monitor on the list. It does not limit itself to usual suspects like dust, toxins, and humidity, etc., going into much more detail instead. We all know the downsides, high levels of volatile organic compounds (VOCs), Particulate Matter (PM2.5) and humidity. But UHOO takes it a step further. It assesses the environment across nine different parameters.
Its ability to connect to smart devices like Alexa, Nest, Google Assistant, or IFTTT is an exciting perk, especially for those who use other smart home devices.

This device has 9 built-in sensors and is advertised as the world’s most advanced monitor. If you have asthma or other respiratory problems, the uHoo is a perfect fit. It goes beyond the basic sensors and gives you readings for other pollutants that are especially prone to cause respiratory issues and flare-ups.
It provides users with a thorough analysis of their indoor air quality so that they can identify invisible but harmful materials, and know when they need to take the steps necessary to rectify their polluted air. The reality is that you won’t be able to feel when your air is polluted — you need a comprehensive analysis like the one offered by this air quality monitor to identify the issue and make changes accordingly.

What reviewers didn't like

We did not get an instruction manual in the box. Compared to other air monitors, uHoo is priced on the higher end.
Does not work without an internet and Wi-Fi connection.
There were some complaints of a difficult set up, but that may be because customers did not realize that it has to connect to 2.4 GHz WiFi, not 5.0.

Since the device has no display, you need to rely on its Android/iOS app to monitor the air quality. A big downside is it has no built-in battery, so you have always need to keep plugged in. Expensive.
Its price probably needs to come down slightly in order to be competitive. While customers have left rave reviews about the actual performance of the sensors, it appears that the initial set-up has been cumbersome for some.
Requires ios 9 or Android 4.3. Costly. Little set up information or information about sensors on website.
