About this app

Introducing Air Score 2.0 and support for PECOAir and PECOAir+. See what's in your air and how to improve it.

KNOW YOUR AIR SCORE
One number for the air in your home, updated as conditions change, with a color band so you know at a glance whether things are good, moderate, or need attention.

CONTROL ALL OF YOUR MOLEKULE DEVICES
Adjust fan speed, switch modes, and manage all your Molekule devices from anywhere. Connects with new PECOAir and PECOAir+ purifiers, Glow Humidifier, and legacy Air, Air Mini, Air Mini+, and Air Pro purifiers.

LOCATION MANAGEMENT
Monitor your air quality by room or by property, wherever you are. If you’ve got a Molekule purifier there, you’ve got a reading.

KNOW WHAT'S IN YOUR AIR
Fast readings from PECOAir's sensor suite: fine particles (PM2.5 and PM10), VOCs, humidity, and temperature. Indoor readings alongside outdoor conditions, so you always have context.

TRENDS THAT MEAN SOMETHING
Get notified when pollutant levels rise, and see what triggered the spike. Look back by day, week, or month to see what's really shaping your air, from cooking and cleaning to pollen and wildfire smoke.

NEVER MISS A FILTER CHANGE
See how much life your filter has left and get notified when it's time for a replacement, so your purifier keeps performing at its best.

*Update 8/24 - I updated to the new app and was able to finally reconnect to the machine. Being able to adjust my dark mode schedule and see the filter status was a relief. Bumped to 3 stars and if it continues to work it'll be a 5!* Great device. Poor app. Same issues as most users. It only connects occasionally. I've been able to control the device through this app maybe three times in the year I've had it. Can't even remember the last time it worked. Disappointing.

We're glad you like the device itself Margaret but we want you to be able to enjoy the full experience consistently and reliably. We have a new version of the app now that's seen an increase in total connection time and we'd love for you to download it and give it a try to see if it's more stable. If not, email reviews@molekule.com so we can help.

Once upon a time I was able to connect my purifier to the app. Ive had my first device for a while now, going on my 3rd filter set since I got it. App hasn't worked for me since the first set. I would have liked to utilize the schedule and filter options on the app, but I've had to deal with just writing the date on the filter and checking it myself. The app can no longer connect to my Full size OR mini purifiers no matter how much I uninstall, unplug, or reset everything.

I've had the product for over a year. I no longer experience connectivity issues when opening the app. I appreciate the app shows you what % you have left for each of the filters. I very rarely log into the app except to check the filter life. Why doesn't this app have notifications to let me know it's time to change the filter(s)? I love the product but the app is very annoying. Please add a Notifications section!!
