Like the sensor, support, and community

I only purchased it about two weeks ago but so far very happy with it. Also, unlike with purely commercial manufacturers there is great community to get answers and learn and someone will pick up the phone when support is needed.

My initial impressions

I like the idiot color indicator's that gives a rough idea of the air quality. I can always look at the web portal for en exact AQI level. USB cord is short, so I purchased a USB extension (might be a good option to have available on website). WIFI signal weak, I had to move several times to get a decent signal strength (my other devices have no issues). Lastly, my device shows grayed out a lot. I have to set conversion to “no” so that it shows zero instead of being grayed out. The annotation says check WIFI, it’s good. After reading on the community board, I believe it’s a PurpleAir issue that needs to be fixed, looks like it’s been lingering for awhile.

I’m still glad, I purchased it. Customer support has been first rate.

Hi Duane,

I know we've corresponded in other areas. But I want to let others know here that the offline sensor is a bug affecting the US EPA conversion on our map. It will be fixed in the next map version.

You might want to show the type of USB plug it needs!

Just one photo showing the type of USB plug is all we need to see. There are a LOT of different USB plugs out there.

Hello,

Thank you for your review and your feedback. For others, all PurpleAir devices use a micro-USB for power.

3rd time is a charm!

I have two outdoor monitors at 2 different properties and I love being able to check in on them especially during wildfire season. I recently purchases an indoor monitor for our offgrid cabin and it's excellent. I was a little worried about the LEDs being too bright and annoying but they aren't bad at all. It nice to be able to walk in the room look over and get an idea of the air quality. Especially when using the wood stove or cooking. I can also monitor it from home when we aren't there!
