01Look beyond the big-room headline
The listing describes 237 square feet in about 12.5 minutes and up to 1,138 in an hour. Those describe different circulation rates, not two equally intensive room sizes.

THE DETAILS THAT MATTERA good find.
A good find.
A closer look.
What it does, who it suits,
and what to check before you choose.
01
02A pre-filter that changes the look
The fabric outer pre-filter gives a softer appearance than a plastic grille. Check the washing and drying directions before refitting it.
03Useful controls at a distance
The app can monitor air quality, adjust settings and show filter reminders. Treat app convenience as a separate decision from airflow capacity.

- App setup and replacement filter availability still matter.
