Yes it reduces Odors!
We own and love other GermGuardian products. It definitely does reduce Odors, we have it in our kid's bathroom (with diapers). It is very quiet. It could work on just the top outlet and keep the bottom outlet available for a slim plug. It has a light that is not bright enough to be a nightlight nor bright enough to disturb anyone but it actually is nice since we have it in a bathroom it provides a little light at night.
