Installation & Smart Home Integration
Unboxing and Setup
All three recommended models are designed for plug-and-play installation. Here's a general guide:

- Install filters (if not pre-installed). Most units have a simple latch or magnetic door.

Smart Home Integration Tips

- Geofencing: Some apps allow the purifier to turn on when you're within a certain distance from home.
- IFTTT: Use triggers like "If outdoor air quality drops below 50, turn on purifier at medium speed."
