I live in California and last year we had a horrible wildfire season. The smoke from the wildfires made it difficult to breathe. Unfortunately, all the air purifiers sold out at Home Depot and Lowe's, so I had to tough it out. This year, I'll be prepared.
This purifier can sync with your phone and measures air quality. You can also sync it to Google Home by linking your Smart Life account with your Google account.
I initially had issues syncing with my phone, but I didn't read the instructions correctly. To sync, make sure the power button is red before you press and hold the WiFi button for 5 seconds. The WiFi sign will then continuously blink and you can sync with the Smart Life app from there.
In terms of noise, this purifier can be pretty quiet. It has 3 fan speeds:
-Level 1 is very faint. I would have no problem sleeping with this on.
-Level 2 is moderate.
-Level 3 is pretty loud, similar to an AC unit. I'd have to talk a little bit louder if I wanted somebody to hear me.
Anyways, this year I'll be ready for wildfire season in California.
