Serene House Cosmos Diffuser vs Airomé Silver Metal Leaf Oil Diffuser

Buy the Serene House Cosmos if you want a simple, well-built diffuser with a metal cover and a long continuous run. Buy the Airomé Leaf if you want a decorative ceramic-and-metal look and more light colors. The Cosmos runs up to 4 hours continuously and 8 hours intermittently; the Airomé runs 3 hours continuously and 6 hours intermittently. The Airomé has a modest 3.5 out of 5 from 10 ratings, so owner feedback is mixed, while the Cosmos has little public feedback to go on.

• Choose the Serene House Cosmos if you want longer run times, a clean white metal look, and a diffuser made in the USA.
• Choose the Airomé Leaf if you want a decorative leaf design with 8 light colors and a removable cord.
