Alen, BreatheSmart 75i_V2
Premium and high in CADR, it comes with a deep Fresh carbon filter, a wide range of sensors, wheels and a well-developed app.
Top pick ifLarge rooms that need certified HEPA, airflow for smoke and more gas media than the typical smart purifier provides
Both the purifier itself and the Fresh replacement filter are costly.
Levoit, LAP-EL551S-AUS
This premium rectangular Levoit delivers strong large-room airflow and adds wheels, an adjustable outlet and unusually detailed particle sensing.
Best forLarge smart homes where you want directional airflow, a unit that rolls and PM1, PM2.5 and PM10 readings
Independent testing backs up its strong particle removal, though the current filter isn't presented as formally HEPA-certified.
IQAir, HPPXE / 123.AB.11.02
Built for both particles and gases, it combines a large HyperHEPA stage, five pounds of carbon-alumina media and the current XE sensing.
Best forSmoke, particles and persistent odors, if you care more about filter depth than about size, price or silence
Expect a 35-pound tower that is expensive, large and noisier than style-focused competitors when airflow is high.
NuWave, 47001 / OxyPure Smart
This large purifier rolls on wheels, automates itself smartly and has several washable stages that cut down on consumable filters without removing the need for them.
Best forLarge rooms, if wheels, automatic operation and washable filtration stages outweigh compact size
Talk of washability can hide the fact that the HEPA-carbon combination still has to be replaced from time to time.
