Not local out of the box, 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.

Buying reality check
Price notes: Around $300 where it is still stocked. Blueair's US store no longer lists the 5240i at all (the US DustMagnet range is now the 5400 series), and UK retailers mark it discontinued, so treat US stock as remaining inventory. Read 2026-10-24.
