I noticed the reviewer mentioned "false advertising" on these vacuum bags. I received real Dirt Devil bags with my order. Not microfresh, but still real dirt devil packs. They are not generic. Maybe the extra filtering is important for allergy sufferers, but considering they're rated for a Featherlite rack (the cheapest in the range) I'm not sure they'll be of that much use. This is not a sealed "allergy" vacuum cleaner. Cheap plastic machines are fairly dust free whether they have a micro filter bag or not. Good price for good packages. Thank you Rewin! I paid half what I have to pay at the grocery store! Five stars and thumbs up! :)
