This is a Hunter Air Purifier, Model 30010. It is a HEPAtech filtration unit.. It is 12" wide and long and only 6" tall weighing only 6 pounds so it is made for tabletop or desktop usage but can be placed on the floor or shelving. It is quiet and doesn't make a lot of noise and has two speeds. It is in good physical condition and working order. It needs a new filter but they last 12 months and only cost about $10.
