The Flow is an amazing invention.

The Flow is an amazing invention. It is an excellent 1st-class quality product. Been searching for a long time looking for something like Flow. Exactly what I am looking for. Very excited with the 24/7 data on air pollution. I now have solid evidence/control to decide what to do with regards to avoiding/minimizing air pollution. I could be wrong but I believe it is the only consumer grade pollution device that measures NO2, the toxic gas mostly coming from vehicles I have received Flow one month ago. I use it all the time, everywhere I go. Very surprised (actually shocked) to find areas having heavy pollution which I have never expected. I have since learned to steer clear of such places. I used to worry about the pollution within and near my house. Now I can see clearly it is not so bad. So glad and relieved. Highly recommended.

Gorgeous, lightweight, highly effective

Gorgeous design in a super-lightweight package, with an intuitive app to manage setup and data. Most importantly, it has a slew of high quality sensors for all the atmospheric nasties you might care about. As far as a personal air quality sensor goes, it’s an excellent addition to the market.

Good purchase for environment-minded consumers

I primarily check air pollution through my Apple Watch (my wife is very sensitive to air quality/pollution), but I purchased a Flow (through the initial campaign) to try and get a more local measurement. It works well and the design of the product is super nice. I wish they would build an Apple Watch app or complication as it would be the killer feature for me. If the team is reading this, keep up the good work!

Highly recommended. Truly revolutionary device when it comes to air pollution!

Flow is an innovative, user friendly way for concerned citizens and scientists to extract quality air pollution data. Plume Labs created a device that allows for users to understand the impact of the air quality on their everyday life. It allowed me to create a narrative regarding the air that surrounds me from my commute to work, daily errands, outdoor activities, to everything in between. It puts air pollution into digestible data that is incredibly easy to understand. Flow tracks PM2.5, PM10, NO2, and VOC with a small, sleek design that is ideal for carrying around. Flow is easy to set up and the app is extremely helpful when it comes to starting up the device. Data transfer occurs via Bluetooth connection. Flow takes air quality measurements every minute, providing extensive data, which is beyond what I could’ve hoped for. Flow is a wonderful invention that allows people to measure and understand the air they are breathing. I cannot recommend this product enough for concerned citizens and scientists alike.

Data is Gold, stock up on it

Few products allow you to quantify really important things in life. This device is giving me the data I need to go to my representatives and show them how toxic my daily biking commute is through Chicago. I did an unboxing here as there seemed to be some confusion from the last reviewer. This is packed as a premium product, and priced like one, so that is good. The device is USB-C powered which was a nice suprise and it has a nice base station to rechage at as it tells me it will need a charge about 1x a day. The flow is right on my backpack like their photos and so far so good. The app is very useful and let's you know the devices charge, air quality, what the numbers mean, adjust settings, etc. Cons: At first I couldn't wake the device up per their instructions, so I plugged it in and it immediately woke up. Not sure why, but could be confusing to those who strictly follow instructions. Will update in a couple months.
