Muji Ultrasonic Aroma Diffuser vs Halo Home Diffuser

Buy the Muji if you want a small, quiet, water-based mist diffuser with a clean minimal look and simple controls. Buy the Halo Home if you want to scent a larger space, move the unit between rooms, and skip refilling and cleaning a water tank. The Muji has the longer track record and a loyal following for build and ease of use, but owners call it small for the money and say the tank runs dry fast. The Halo Home scores higher with far more ratings and offers cordless, waterless operation, though it is a newer brand with less independent testing behind it.

• Choose the Muji Ultrasonic Aroma Diffuser if you want a compact, quiet mist diffuser for a bedroom or desk and prefer the simplicity of water and a few drops of oil.
• Choose the Halo Home Diffuser if you need to cover a bigger room or want to carry the diffuser from room to room without a cord or a water tank.
