This is a serious (but weird) question. I wonder how thin panty liners would work as a filter.
Better suggestions:
1) vacuum cleaner bags with allergen filters
2) coffee filter #4
3) swifter dry sheets
Plastic is generally not a good thing.
Also, need to keep in mind breathableness.
We can’t tell without testing. If you remove the plastic liner, how breathable would they be as a filter? I know some of them advertise that they’re ‘breathable’, but I doubt that’s what they meant for our new purposes.
