MUJI Ultrasonic Aroma Diffuser vs Serene House Twilight Glass Diffuser

Buy the MUJI diffuser if you want a small, quiet unit for a bedroom or desk and value a warm, dimmable glow. Buy the Serene House Twilight if you want longer runs, a bigger tank and colored mood lighting. The MUJI is the more compact, minimalist object and owners report units lasting years. The Serene House covers more room time per fill, but its glass cover is heavier and more fragile, and its colored LEDs suit ambiance more than sleep.

• Choose the MUJI Ultrasonic Aroma Diffuser if you want a compact, quiet diffuser with a warm two-level light and simple timers for a bedroom or small office.
• Choose the Serene House Twilight if you want longer mist sessions, a larger tank and colored rotating lights for a living room.
