With the constant fires in our region, we've long trusted Purple Air to help us know if we've properly sealed off our house when disasters strikes outside. It's how we keep safe and healthy. I've had one since 2018 that still works fine, and have bought a number for friends and relatives over the years. I recommend them to anyone who asks.
Charging us for data is wrong wrong wrong.
We are really mad. We have 12 outdoor and 5 indoor monitors. We will not be purchasing any more. We were so happy that we finally found someone to analysis our data and then the charging for data downloads happened, shame on you. You know that citizens and community groups are using these monitors to bring relief to the air pollution we are seeing in our overburdened communities and then you charging is adding insult to injury. Shame.
Cynthia, please reach out to us on contact@purpleair.com and we will give you points to access the data for your devices. Why do we charge for data now? Up till now, you have been supporting the network by paying for your sensors. Lots of data was then downloaded by anyone and everyone for free. You supported that. So now, to make it more fair, we are getting the data consumers to pay their share to help support the network. Anyone with this same type of concern should reach out to us to get some points or a discount to access data. We certainly want to help you.
Yes, it is expensive. For the money, should I have bought another outdoor version and used it inside (so I would have the dual lasers) ? Probably. Are there cheaper competing products that would also give me a simple indication of indoor air quality? Certainly.
However, this is simple and attractive. The LEDs are adjustably visible, and give that wonderfully effective non-technical feedback that is easy to explain.
Installation was a breeze - exactly as described in the guide.
Knocking off a star for the price, even with the discount. But I enjoy the Purpleair ecosystem, so there is pleasure in adding this to the existing outside sensor that has worked without a single hiccup for 5 years.
My Outdoor sensor from Purple Air gets a "brother" for Air Quality Indoor measurement. A new eyecatcher for my living-room.
A short look to the green light, evertything fine, and it doesn't need much energy, <1 Watt!
High quality without further action!
Only installation, that's it.
And it works, it works, it works...
WUNDERFUL
Purple air indoor sensor helped determining that using the front burners of my stove every morning for cooking breakfast was a air quality killer as the fans were not venting the smoke properly . Moving to the back burners had a significant difference. I don’t understand why the manufacturers aren’t doing anything about it.
