No noticeable difference
I ran this plug-in unit in my large bedroom with the door open and closed and in a small bathroom with the door closed - both with a cat litter box inside hoping to clear to associated odors. I am sorry to say I did not notice any difference in odor with or without the unit. Closing the door did not help and switching it to the smaller square footage area did not make a difference. It is not silent - it makes a moderate amount of noise. I definitely needed to move it away from the head of my bed to not disturb my sleep.
