After using the Sebo D series vacuum cleaner for the past year, I no longer sneeze after vacuuming. The bags are easy to install and easy to dispose of. Allergy sufferers will appreciate this machine and bag filter. Once I lost a diamond and couldn't find it. I vacuumed the bedroom then opened the top of the vacuum and here it is. The bags are a bit more expensive but I save by not having to take any medication.
