If you are allergic I would recommend skipping these and buying 12 Electrolux Upright Style U Allergy Vacuum Packs Aerus, Epic, Prolux, Discovery, Genesis, Lux Vacuum Cleaner, 2500, 3500, 4000, 6000 which are also available at Amazon are available. They seem quite thin in comparison and don't seem to have multiple layers to filter the air. They go quite well with my Electrolux 6000, I just don't think they're that effective.
