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.

Verdict
The clearest difference is review sentiment: PuroAir at 63% against Molekule's 17%. PuroAir also leads on rating (5.0 vs 4.4). Molekule's advantage is ratings volume (12K vs 4) and monetization model (free vs ad-supported). On price, update cadence, ads and in-app purchases there is nothing between them.
