Febreze Small Spaces, Plug in Air Freshener Alternative for Home, Gain Original Scent, Odor Eliminator for Strong Odor (4 Count)

The scent is strong enough to cover up the worst bathroom odors without being overpowering, and I love how long each one lasts. I just screwed it into the outlet in the corner and haven't had to think about it since.

My bathroom was always a bit musty, but one of these in the corner completely eliminated that smell. The Gain scent is subtle enough to not be overpowering, yet it really neutralizes strong odors.

I put one in the guest bath and even after a week the Gain scent is still going strong—it actually neutralizes smells instead of just layering perfume on top.
