Title: The air stinks, but my sinuses are clear
Review: The title says it all. The smell that the filter emits is hard to describe but certainly unpleasant. On the other hand, I no longer have clogged sinuses and a post-nasal drip. My sense of smell is more acute (I can smell how much I stink now) and my bad breath is disappearing.I wish I'd bought a higher-quality one, but I'm just glad I bought one!
