I pay attention to how strong the scent is. Some diffusers spread fragrance gently, while others are more powerful. I usually choose based on room size. For a small space, I don’t need a strong output, but for a larger area, I want better coverage.

7. Refill Type and Compatibility
I make sure the diffuser works with the kind of scent oils or refills I want to use. Some models only work with specific cartridges, while others allow more flexibility. I usually choose the one that gives me more options.
