Homedics SereneScent Flow Diffuser vs Aviva Waterless Diffuser

The Aviva is the better pick for most people: it runs on standard 5 ml and 15 ml essential oil bottles, covers about 400 sq ft, and has continuous and intermittent timers with auto shut-off. The HoMedics SereneScent is the step up for a living room or bedroom where you want set-and-forget scent and a remote, but it locks you into SereneScent oils and never mists continuously. Owners of the Aviva praise the no-mess, no-buildup diffusion and long service life, but complain about slow charging, a hard-to-grip bottle, and units that failed after being tipped or after extended use. The HoMedics is fabric-wrapped and cordless with three intensity levels, and its waterless design means no water to measure and no heat.

• Choose the HoMedics SereneScent if you want a cordless, fabric-wrapped unit with a remote for a larger room and are happy to buy SereneScent oils.
• Choose the Aviva if you already own 5 ml or 15 ml essential oil bottles and want timed continuous or intermittent diffusion in a small, portable unit.
