The only eliminator I will ever trust again! I got ripped off by the other guys already! It functions like a dream! I bought two more the second I opened the package, I was ordering two more! That's the value you get for the initial investments super worth it, you get a step by step directions on how to make sure it smells nice, cleaning is a snap. It's a HEPA filter so I don't think you're going to get much better. If you follow the directions I'm sure it's going to last way longer than any of the competitors, which in my opinion has no equivalent. It's great lifespan and filter quality with the docking station just in case, you are going to be feeling great about this purchase! I would like to add the customer service and support is top notch!! I got a human right away and he was very knowledgeable and eager to see me happy and made sure I was satisfied with everything. He definitely deserves a good rating for leaving the rest in the dust and you deserve to take back your crumbs. Dennis C. Is giving his crumbs to this amazing product
