I'm on a mission to lower/remove the "dog smell" in my house and would love any advice from anyone who's had any luck doing so. My roommate and I have a total of four dogs (beagle, lab, and two nuclear-reactors with fuzzy paws, also known as border collies). They all get fairly regular baths, there are pretty much no "accidents" (but if they do happen, they're SpotBot'ed up immediately), we run the vacuum frequently, and the dogs' beds are washed frequently. My neighbor, who worked many years for a disaster restoration company (using professional ozone machines to get the fire/mold smells out of people's houses), uses a Eqoquest Fresh Air (ozone) machine in her house. She has a ton of pets and zero pet smells. You also can't smell the ozone (which I guess smells like lightening) in her house. I've done a bit of googling on the matter and am fairly confused by the results. Some people swear that ozone, done properly, can remove funky smells. Others rant and rave about the multi-level marketing method that's used to sell a lot of ozone machines (but don't really comment on the machine's effectiveness). Others make it sound like you'll immediately get lung cancer if you turn the machine on in your house. Having seen it in action at my neighbors house, I'm inclined to believe that it really works. Anyone have any experience with these?!
