I worked in an Oreck store part time for 8 yrs. and the Hepa bags have been around for a long time. First they were gray, similar to the "new" odor fighting bags from Kirby, then they went white, and I think they were better. A couple of weeks ago I visited the store where I worked to get a charcoal filter for my air purifier and they just got an order in from Oreck. The bags have changed material/color again, the new one being kinda purple/magenta-ish, 5 layers, and nothing in print about them fighting odors, and get this only 6 in the newly designed box, and went up 2 bucks! I asked the mgr. if they were the new odor fighting bags and he said yes, but hadn't read the box, but nothing mentioned about fighting odors. I have a shedding dog, so I really appreciated them. Sooo, I go out to a friends vacuum shop who normally orders my bags for me, and low and behold, the new ones came in, from Oreck, and nothing about odor fighting on them either, ugh. Oy vey, thank God I don't pay retail. Thank you TTI!
Devin, I hear ya about the noise comparison between the Tacony versions and the XL21. I found the green one like in the above pic in a thrift store for 20 bucks, and nothing wrong with it. While it cleaned well, it was louder and seemed to have a higher pitch to the motor. I took it out to the shop I frequent and they tore it down to check the fan, again, nothing wrong. I resold the RSL3 I believe it was. When I use the XL21, my dog doesn't freak, but if I use one of the other Orecks, and when I used the Tacony version, she left the room! There is something pleasing to me with the sound of the XL21, the original. Once they changed to the Platinums, the plastics became cheaper as well as the bag material. Thanks again TTI!
