Candlelight Flame Ultrasonic Diffuser vs Serene House Twilight Glass Diffuser

Buy the Candlelight Flame if you want a flame-effect diffuser for a nightstand, desk or small bedroom and want the longest run time per fill. Buy the Serene House Twilight if you want a taller glass piece that looks like decor and gives you timer and color-light control. The Candlelight is smaller, lighter and quieter on paper, with a 120ml tank and up to 6 hours of mist. The Twilight is a 19cm textured-glass tower with 7 LED colors and 60/90/120-minute timers, but its 0.9L volume figure and its 4-hour continuous rating don't line up, so treat the run time as the safer number. Owners of both types praise the quiet mist and the auto shut-off.

• Choose the Candlelight Flame if you want a compact, near-silent diffuser with a realistic flickering flame glow and a full night of mist from one fill.
• Choose the Serene House Twilight if you want a taller glass diffuser that doubles as decor and lets you set a timer and pick from 7 light colors.
