Even if you don't have allergies, HEPA bags are a must. Have you ever worked on the motor (torn it down completely) in one of your old Lux's? The fans are packed in dirt. Why? Paper bags. Paper bags leak dust. That dust goes into the fans, and then into the exhaust. I vacuum my house to remove dust. The vacuum should NOT have ANY dust in the exhaust, or I'm wasting my time dusting the furniture with it. To that extent, I have a Vac U Flo central vac - absolutely no recirculated dust. My Elux Platinum, Tri-Star MG2, Rainbow 75th Anniversary Edition, and Air-Way Signature Series all have HEPA filtration - and leak no dust. It's not about allergies, it's about not having to redust my television screen tomorrow. That's why HEPA makes sense to me.
