Scentiment Diffuser Air 2 LE vs TANOXI Smart Waterless HVAC Diffuser

The Diffuser Air 2 LE is the better-built machine: recycled aluminum housing, an interchangeable motor, and a large base of 332 ratings at 4.6. The TANOXI covers more space on paper, holds a much larger bottle, and runs up to 30 days per fill, but it is ABS plastic and has only 13 ratings. Buy the Air 2 LE for a living room or office where build quality and a proven app matter. Buy the TANOXI if you have a large open floor plan and want to refill rarely.

• Choose the Diffuser Air 2 LE if you want aluminum build, a replaceable motor, and a diffuser with a long track record of owner ratings.
• Choose the TANOXI if you need to scent a very large space and want the longest possible run time between refills.
