Recommendations for shared diffusers!

With the hot weather and high humidity, the smell of mold and mustiness fills the air during the summer, doesn't it?

I'm trying my best to prevent it by organizing and cleaning, but it's not easy.

So I'm looking into diffusers~ I'd love to get some recommendations from our Unpa members^^

Are there any cost-effective diffusers available that can be used in the living room, bathroom, entryway, and even the car?

I like the scent that isn't too strong and lasts a long time~ haha
