Levoit Air Purifiers for Large Rooms

For open-plan living areas and larger bedrooms the figure that matters is CADR — how much filtered air a unit actually moves per hour — rather than the square-footage claim on the box, which usually assumes a single air change. Levoit's Vital and Eleva models sit at this end of the range, with higher flow rates and correspondingly larger filters. The practical trade-off is noise: a unit sized correctly for a big room can run on a lower, quieter setting, whereas an undersized one runs flat out and is more intrusive.
