The Italian lemon cuts through the eucalyptus in a way I didn't expect — it's bright without being sharp. I've got one running in the bathroom and the whole hallway picks it up within a day.

The 2-pack means I'm not swapping cartridges every couple weeks, which is exactly why I switched to a refill bundle. The Italian lemon cuts through the eucalyptus so it doesn't smell like a cough drop.

I grabbed the 2-pack so I wouldn't run out mid-month, and the refills click in just as easily as the originals. The eucalyptus oil smells clean and sharp without being overpowering, and I like that it's pet-friendly since my cat naps in that room.
