Items received was not what was advertised or pictured. First you do not get the 3 layer/3 color filter you expect to be Hoover. It is all white and thin. Until you read the back of the package it's for use in most Hoover product "EXCEPT" upright wind tunnels. Item is virtually useless and too cheap to bother returning. It went from my mail to trash.
