Necessary Filter Replacement
Your review: The Pullman-Holt vacuum that uses this filter is a solid, reliable vacuum and this filter is reasonably priced. We collect fine particle size powder that this filter becomes loaded with, yet is able to be cleaned out with the use of compressed air. As a system this filter provides the rated HEPA filtration we require.
Pros: Solid reliable construction
Cons: Not the easiest to remove and replace as it is built into the lid. Care is needed if you do attempt to blow out any collected dust so as not to tear the media.
