Scenta Basic Waterless Diffuser vs BlueHills J02 Waterless Diffuser

The Scenta Basic is the better pick for most homes: it takes standard 5/10/15/20 mL bottles, has three mist levels and four timer settings, and runs up to 48 hours on a charge. The BlueHills J02 claims larger coverage and an aluminum body, but its listing details are thin and it has only 14 ratings. Buy the Scenta for a bedroom, office or spa room; buy the BlueHills only if you want a metal travel diffuser for a car or a bag.

• Choose the Scenta Basic if you want a waterless diffuser for a fixed room up to 600 sq ft and you use standard 5 to 20 mL oil bottles.
• Choose the BlueHills J02 if you want a cordless metal diffuser to carry between a car, a desk and travel bags.
