Auto mode reads a particle sensor and speeds the fan up when the air gets worse. That's the "smart" part worth paying for.

| Pick | Notes | Source |

## What to check

- **CADR for your room size.** The [AHAM Verifide](https://ahamverifide.org/) program lists tested numbers.
- **Filter cost per year.** This is the real price over time.
- **Sensor type.** PM2.5 is standard; some add VOC or gas sensing.
