Why would you use BOTH? Hoover WindTunnel Upright Type Y Vacuum Bags Microfiltration with Closure – 9 Pack Hoover and
# Hoover 4010100Y WindTunnel Allergen Filtration Bag ?? What are the difference? I am trying to learn which on I need… which one is for dust mite, dead skin, allergy ???
The allergen-filtration bags filter out small particles so that they don’t re-enter the air in your room. Good for allergies. They are very expensive, though, so I use the regular ones and try to vacuum more often to get out most of the allergens.
