Bests & Worsts Reviews from Amazon

so far this air purifier is performing beyond what I expected. My daughter has a ferret and a mouse and fish in her room. Many times after the door is shut for long periods the smell is horrible. One night of this running so far with the fan on medium, and the odor seems to be almost completely gone. We ordered a second purifier for a room downstairs. I haven't investigated purchasing replacement filters quite yet, but we are pleased.
