I didn't notice a difference until I put it by the sink and it got rid of the smell of dishwater/soaking dishes entirely.  It's small and compact and I like that it plugs right into an outlet without needing a cord.  It's not very loud and it has a very subtle white LED that glows a bit at night.  I'll be buying another one for the catbox room.<br /><br />UPDATE: This thing is AWESOME for the catbox room.  It almost completely got rid of the wafting smell of cat litter (not talking cat poop, just the smell of the litter that accumulates. We have three cats and two very large rubbermaid tubs for cat boxes - even with cleaning every day the smell of the litter can be obnoxious) by itself when two full room sized air purifiers (one a tower and one a tabletop) failed miserably.  I was so excited I ordered one of the newer models by GermGuardian for another room! I'm really impressed, and I'm glad I'm not smelling litter anymore.
