Blueair DustMagnet 5240i

Quick verdict

Not local out of the box and included mainly as cloud filler, though an unofficial local API proxy exists for advanced users. It leans on the manufacturer cloud, so treat it as a fallback when local options run short.

Standout: HEPASilent dual-filtration purifier with a distinctive dust-magnet pre-filter design and a community HA integration for fan and AQI control.
