4 options

Alen, BreatheSmart 75i_V2
A high-CADR premium purifier with a deep Fresh carbon filter, broad sensor suite, wheels and a well-developed app.
Winner whenLarge rooms needing certified HEPA, smoke airflow and more gas media than a typical smart purifier
The purifier and Fresh replacement filter are both expensive.

Levoit, LAP-EL551S-AUS
A premium rectangular Levoit with strong large-room airflow, wheels, an adjustable outlet and unusually detailed particle sensing.
Best forLarge smart homes that want directional airflow, mobility and PM1, PM2.5 and PM10 readings
Independent testing supports strong particle removal, but the current filter is not presented as formally HEPA-certified.

IQAir, HPPXE / 123.AB.11.02
A serious particle-and-gas machine with a large HyperHEPA stage, five pounds of carbon-alumina media and current XE sensing.
Best forSmoke, particles and persistent odors when filter depth matters more than size, price or silence
The 35-pound tower is expensive, large and louder than style-led competitors at high airflow.

NuWave, 47001 / OxyPure Smart
A large rolling purifier with smart automation and several washable stages that can reduce: but not eliminate: consumable filters.
Best forLarge rooms where wheels, automatic operation and washable filtration stages matter more than compactness
The washable marketing can obscure that its HEPA-carbon combination still needs periodic replacement.
