Look no further, Allergyfreebags.com has located a bag that will work in your Defender F-16 vacuum cleaner!
This one of a kind vacuum made by Mark O'brian in St. Johnsbury VT.
These bags are single ply which means not multiple layers. We are hoping someone will make a higher filtration bag in the future.
If you are needing filters for your Defender F-16 vacuum check out the cut-to-fit material listed above. You can use the thick micron 3 layer by itself or for added filtration combine with a layer of the charcoal material.
How hard it is to make the filters using the cut to fit material? Simply take your old worn out filter and trace its dimensions on a piece of paper. Then cut out that shape carefully. Next pin the clean paper pattern on the cut to fit material and cut of the shape. You now have a new filter! You should have enough material in a small sheet to make a few filters.
