*The PIXEL is currently on backorder and has an expected ship date of February 1st.

Featuring the Bosch BMV080, the world's smallest particulate matter PM2.5 detector, this revolutionary new type of air quality sensor has no moving parts. Using convection, air moves gently through the sensor, so it is absolutely silent. The multi-colored LED lights illuminate with the color of the AQI, providing immediate and at-a-glance particulate (PM2.5) air quality readings.

Powered by USB, this simple device has no WiFi or Bluetooth, which ensures plug-and-play simplicity with no additional setup required.

PurpleAir PIXEL

Compact and very responsive to air quality change.

least expensive and smallest Purple Air device

No wifi. The colors, green, yellow, orange, red, may overlap in the display. I guesstimate the reading. If it's plugged into my PC, I use the "Purple Air Tools", and my visual reading may be 10-20 points lower than the digital reading. YMMV.
The Pixel has seven brightness levels, bright to very bright. It's too bright for my room at night, so I cover one side of the Pixel with Scotch Magic Tape.

Good, but not great...

Four stars only because it only works as designed: The actual fulfillment of purpose is more nuanced:
* If it had a male USB-C could it just be plugged into a phone?
* How much more expense or increase in form factor would there be if it displayed numbers instead of or in addition to colors? Colored numbers? This is obviously critical because AQI 49 is green and 99 Is yellow, etc. (I like that blends colors as with the rest of the PA communication system.) I see a review that mentioned this issue from 10 months ago...
* The unit seems strong and solid, perhaps even if dropped... The weak point of course is the USB... Some type of tiny protector for it would be great... A custom case?... I would love to wear it around my neck, could be beneficial for the brand if it's colored purple...

***

There's a larger issue of course which is the responsibility of EPA: the current rating and color scale is completely inadequate as it simply makes things seem better than they are. A small part of the reason is that the colors abruptly shift, and I appreciate that you guys do that blending thing. But according to EPA, AQI 62 is at the safer end of Moderate... 62 is also the recommended maximum by the WHO for 24 hours of exposure.

Super Useful

I need to be able to check air quality around town on the go. I can easily jack this into my notebook at different places around town and instantly check the air quality. With the PurpleAir tools app, I can also gather the real-time readings and logs should I need them.

Smoke Report from Winnipeg Canada

An air quality health index search in Google brought me to purple air.com. I was amazed at the map presentation of the air quality. The summer in Winnipeg this year has been extremely smokey. I bought the unit to measure & monitor interior home air quality. Using a portable USB battery pack I was also able to monitor outside and in the car. It verified the inside of my car air is also know better than ambient despite a new premium cabin air filter. I’m very happy to purchase this device I would recommend anyone get it.
