From the Manufacturer
Not all sensors are created equal - and where health is concerned, precision matters! The Node combines cutting-edge laser technology, airflow control, and a crafted calibration algorithm to achieve the most accurate data available on a consumer device.
Compare indoor ratings from the Node’s sensor with outdoor ratings taken from your nearest monitoring station* to discover sources of pollution and know when to open or close your windows. *Check airvisual.com/world for outdoor station availability.
Use the Node’s internal battery, storage and high precision sensors to take measurements at home, in the classroom, car and beyond. The Node was developed with researchers, HVAC professionals and curious individuals in mind. Retrieve your data wirelessly, analyze it and reach your own conclusions.
Be proactive in avoiding harmful outdoor air pollution. AirVisual uses in-house data and machine learning to forecast air quality in 8,000 locations worldwide*, helping you stay prepared and plan your activities for the healthiest times. *Check airvisual.com/world for outdoor station availability
Many places around the world still lack local air quality data. By placing your Node outdoors and designating it as a public outdoor station, you become a data source - providing neighbours, researchers, and policy advocates valuable information about your local community.
The Node’s bright 5” screen uses easy to understand, color-coded symbols to quickly convey your air quality at a glance, without having to rely on an app. Watch the display rotate through indoor and outdoor AQI, CO2, air quality & weather forecasts and personalized advice.

How did you come up with the idea for this product?
Having lived in Beijing for two decades, a city with 8 times the WHO-recommended pollution threshold, we sought to better understand the risks in the air we and our families were breathing, indoors and out. With a background in big data, sensors and IoT devices, we were able to bring a novel approach to the pollution problem, empowering people to improve their health and productivity by providing them with the data and information they need. The Node helps localize the air pollution challenge down to the individual, making a seemingly daunting task as manageable as a single room.
What makes your product special?
The Node goes a step further than other monitors, giving you the biggest picture of your air quality. It shows you exactly where you stand, considering indoor and outdoor air, and showing you both historical, real-time and forecast data. It takes professional-grade, accurate measurements and visualizes these in a colourful and easy-to-understand way on-screen so that children, parents and passers-by alike can benefit from knowing their environment, and how to respond. Its internal battery allows people to pick up the Node, walk around and immediately see changes in your air quality on the Node’s screen.
What has been the best part of your startup experience?
Critical to launching the project off the ground was a successful crowdfunding campaign via Indiegogo. Through the campaign we were able to connect with supporters in over 35 countries worldwide, offering tools to improve their wellbeing and democratize their local air quality. The Node’s unique ability to be placed outdoors and listed as a public outdoor station has helped provide local communities which previously lacked air quality data, with the information needed to generate awareness and help improve people’s health. AirVisual is now the first to report live outdoor air quality in Saudi Arabia, Cambodia, Pakistan, Italy and the Philippines - with significant results! Sound interesting? Let us help you get your local air quality on the crowd sourced map!

I bought this device because it measures PM2.5. The popular Awair device, though it's hard to find specs for what it really measures (it's not even in the manual - that's not a good sign), apparently measures PM10, and PM10 as far as I know is not a good indicator of the kind of pollution that most impacts your health, that's what I care about.
It's been very useful to know when to open the windows and when to keep them closed. Since I don't (yet) own an air purifier, I can only open the windows when pollution outside is low (which the PM2.5 sensor lets you know if you put the device outside for 10 seconds).
The first surprise was to learn just how fast CO2 builds up when the windows are closed. I live in a small, 500 sq. ft. apartment. When the windows are open for a while CO2 gets down to about the outside level (below 500ppm) and in just a few hours with the windows closed it's over 1300ppm and rising - and that's assuming I don't close the room's door. Too bad even levels as low as 900ppm have been found to degrade mental performance in some cognitive tasks. (Keep in mind that the degradation of performance is only temporary. I don't think there are long-term effects of exposure to high CO2 in these ranges.)
So the first thing I learnt is this: I should keep the room's door when possible. Otherwise, CO2 goes up pretty fast in these small rooms.
The second surprise lesson was this: the stove, and even more so the oven, raise CO2 levels really fast. Someone cooking a pie for 40 minutes in our natural gas-powered oven takes CO2 levels in the entire apartment over 3000ppm. I knew that natural gas combustion produces CO2 but I didn't know it produces so much.
Another lesson was that the morning is an ideal time to open the windows, however cold it may be outside, since PM2.5 pollution is low in the morning all the way to around 4pm, when houses in the neighborhood begin firing up their fire places and emitting smoke -- and then it gets really polluted! (And that was another surprise. I know wood smoke is bad but I didn't know the pollution here in winter is SO bad.)
I would like to have another brand of sensors to compare the measurements for accuracy, but so far I haven't seen anything to make me doubt the accuracy. The measurements make sense.
Well built, stylish, looks like Apple designed it.
An added bonus, the node’s forecasting ability is wonderful, letting me know if it’s safe to open windows for fresh air.
