Smart compact unit.
Ordered the Air Balance. Recieved couple of days later. Well packaged with the additional free HEPA filter.
Smart compact unit, great easy to understand touch control panel on top. Instruction manual very easy to understand.
Used on sleep setting first night, very quiet running.
Felt so much well rested the next morning. Seems to have helped me get a proper nights sleep.
Impressed so far, worth the cost? I'd say YES.
