Rowe Casa Glass & Concrete Diffuser vs Now Ultrasonic Real Bamboo Diffuser

Buy the Rowe Casa Glass & Concrete if you want a larger tank, longer timer options and a diffuser that doubles as decor; its 4.8 rating from 295 owners is strong, though a few report the touch button is finicky and units that quit after a few months. Buy the Now Real Bamboo if you want a proven ultrasonic design with a one-year warranty, auto shut-off and a smaller footprint for a desk or office. The Now runs longer per fill in intermittent mode and covers a stated 400 square feet, but its 3.9 rating from 39 ratings is thinner and lower.

• Choose the Rowe Casa Glass & Concrete if you want a 200ml tank, 4- and 8-hour timer settings and a glass-and-concrete look that suits a living room.
• Choose the Now Real Bamboo if you want a compact BPA-free diffuser with a one-year warranty, auto shut-off and up to 14 hours of intermittent run time.
