Air-Way
Ken,
I'll be glad to share with you what I know about the bag situation at Air-Way as I am a distributor for them in Charlotte, NC.
The paper that was being used for the original 14 and 28 layer bags is not longer made in the U.S. Air-way found another manufacturer outside the U.S. but the cost was prohibitive and they actually took a loss on the last "batch" that was made.
They did find a paper, the new current blue color, that they assured me was of superior filtration over the wood pulp cellulose paper. I have not done any scientific testing and take their word for it. The new bag only comes in one layer type because of it's superior filtration.
Contrary to what may have been said or posted, it is NOT a filtrete paper but more of spun fiberglass type material and in using it in my own home seems to be just fine. Also, contrary to rumors, the equipment made to sew the bags is also NOT the reason they changed paper.
As with any large business, changes are bound to occur due to availablitly of product needed for manufacturing. Air-Way still makes one of the finest, (arguably if not the best), canister/tank vacuums available. As long as you continue to use genuine Air-Way bags and filters, the vacuum will last your lifetime...........unlike many others.
I'm not sure why your bags are two tone other than Air-Way is using up their inventory of the wood pulp cellulose paper. I was told that the double layer bags would no longer be available. I need to call Air-Way for ordering and will inquire. Also, I will ask about the stickers.
Hope this helps somewhat.
