Prefilter (5-Pack) is rated 4.0 out of 5 by 5.
Rated 5 out of 5 by from Seems fine I used duct tape (cut a hole in it to allow air thru the filter) to attach it to the hood I bought from HD, since I did not buy the mask system that goes with the hood.

Rated 1 out of 5 by from bad The 5 pack had 2 filters and the black piece that holds the filter was not included. Shows a picture of it, but does not come with it. Had to go somewhere else to buy the hood because this one is useless for sandblasking without all the parts.

Rated 4 out of 5 by from photo totally misleading. Filters only. No plastic black 'keepers" to hold filters in place. Parts were missing. I need to return to the store.
