Take a closer look at the bags. HEPA filters down to 0.3 microns at 99.97% efficiency. This means that 99.97% of particles larger than 0.3 microns are trapped by the filtration media. I'll guarantee you that the bags you have don't trap down to 0.1 microns at the same efficiency rating as HEPA.
It may filter down to 0.1 microns at 80% efficiency, meaning 80% of particles larger than 0.1 microns are trapped. But HEPA filters better than this.
Don't pay attention to things that tell you what micron level they filter down to without telling you what % it filters down to. You will not find a consumer vacuum (or probably any vacuum) that filters down to 0.1 or even 0.3 microns at full 100% efficiency. HEPA is the gold standard for home vacuums, ULPA is a level that's even better than HEPA, but you won't find a dustbag that filters down to that level. ULPA is still only 99.999% efficient.
