Thanks, I do also buy NOS genuine 4 ply bags and have Germgrabber and Surething bags that are in my machines. I gave a friend an Electrolux 2100 that I used to have. He has two kitties, one long haired and one short haired. Bags only last a few weeks, due to the amount of cat hair and kitty litter tracked out even with mats in front of each of the covered litter boxes (3). That is why I tried the DVC brand bags and found that they do filter very well. I usually change the bags for him when the automatic control signals a bag change. That is how I know they filter so well, very little dust in the bag compartment. I would not be afraid to use the 4 ply DVC's in my Electrolux vacuums. I wrote about the Aerus bags in detail in a post some time back, noting that their new two ply that they toot to be better than the original 4 ply was not better at filtering. Note: The 2 ply instead of 4 does not hold up well, the 2nd inner layer pulls away and tears away and rips from the outer bag, putting you down to 1 layer filtration.....I haven't bought any since. When I do buy a new machine, I will use the genuine, just to protect my warranty....hopefully they have addressed this problem by now.....I will say this, they did ask me to send them a bag to show them what was happening, which I did. They gave it to research and development to look at. I never received a response back, but did receive a brand new box of C bags at no charge for my effort.
I am a die hard Electrolux fan, no bashing here, just the facts as I know them up to this point. PS This was a few years ago and as I have said, my fix was to buy NOS 4 ply bags.
Sincerely,
