Diffusers & oils · sized by the cubic foot
Most diffusers are the wrong size for the room they sit in.
A 160 ml desk unit cannot scent an open-plan floor, and a big one in a bedroom just gives you a headache by 9 pm. Measure the air first. The machine comes after.

That is a refill most days. Fine on a nightstand; annoying in a shop — the next size up holds three times as much.
The machines
Three, not thirty
Same glass tank, same quiet pump, same 120 V UL-listed adapter. The only real difference is how much air each one can keep up with.

Why size matters
Nose blindness is
an overdose problem
Put too much scent into too little air and you stop smelling it within twenty minutes — then you turn it up, and everyone walking in gets hit in the face. An under-run machine in a correctly sized room stays noticeable all evening.
