The Smart Air Purifier 400S is an intelligent air purifier.
It can be connected to WiFi (2.4GHz only) or operated remotely via the companion mobile app.
Controlling different settings via an Echo smart speaker is possible by connecting it to Alexa.
It is very easy to use the app and offers all the same settings as the control panel. In addition, you can set a timer (for 1, 2, 4, or 8 hours) and schedule the purifier to turn on or off at a particular time.
Many owners who had verified their ownership complained that there was no way to turn off the bright display light a few months back. This issue has been solved.
You can set the time when the light will turn on and off according to a schedule.
To voice-control the unit via Alexa, you will need to enable the Airmega skill in the Alexa app.
You can then tell Alexa:
- Turn Airmega on/off
- You can activate a particular mode.
- Change fan speed
- Turn the light on/off
- Set a timer
- Check the filter’s lifetime
- Get an air quality update.
- Monitor Real-time Air Quality
The Airmega 400S has an integrated pollution sensor, which continuously measures the air quality.
The brightly colored LED ring on the front can show you how your home’s indoor air quality is. It will change color depending on how dirty your air is.
The app is useful to check for current air quality readings and a history of air quality reports.
