Choosing the right diffuser comes down to three things: how big the room is, how much control you want over scent strength, and whether you need a plug-and-forget solution or whole-space coverage. Here's how our four most popular diffusers compare.
Lumix Plug-in Diffuser: best for small rooms and bathrooms
The Lumix Plug-in Diffuser is built for compact spaces like bathrooms, closets, and small bedrooms up to roughly 300 square feet. It plugs directly into any outlet, uses adjustable intensity settings, and is ideal if you want consistent, low-maintenance scenting in one room without moving parts or a bulky footprint.
Tower Diffuser: best for living rooms and open layouts
For medium to large rooms, the Tower Diffuser uses fan-driven cold-air diffusion to push scent further, making it a good match for living rooms, open-concept spaces, and rooms up to around 800 square feet. It sits on a shelf or floor rather than an outlet, so placement is flexible, and timer settings let you control how often it cycles through the day.
AirLUX Plug-in Diffuser: best for multi-room coverage on a budget
The AirLUX Plug-in Diffuser is designed to be used in sets, so you can place one in each of several rooms for consistent scenting throughout a home or apartment without needing a single powerful unit. It's a strong choice for hallways, entryways, and secondary bedrooms where a lighter, steady scent is enough.
Max HVAC Diffuser: best for whole-home or commercial scenting
When the goal is scenting an entire home or a commercial space through existing ductwork, the Max HVAC Diffuser connects to your HVAC system to distribute fragrance evenly through every vent-connected room. This is the option to choose for large homes, offices, retail spaces, or anywhere separate plug-in units would be impractical to manage room by room.

Still not sure which fits your space? Consider starting with one unit in your most-used room and expanding from there once you've dialed in your favorite scent strength.
