  Notice that there are different HEPA filter categories, just saying HEPA
should not suffice when choosing a vacuum for museum use (a minimum of H13
is required for museum use).
     https://urldefense.proofpoint.com/v2/url?u=https-3A__en.wikipedia.org_wiki_HEPA&d=AwIFaQ&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=CLFZJ3fvGSmDp7xK1dNZfh6uGV_h-8NVlo3fXNoRNzI&m=Gwlz1WWzyiQO7AHw8dUUQNlF2HwbHdh86pSyVk7zJoU&s=cBpWz8YqdBXlQ8kxcvwh_M3v72q29N4H63yWlciU_0Y&e= 

   Notice about ULPA filters as well (surpassing HEPA in filtration)
      https://urldefense.proofpoint.com/v2/url?u=http-3A__www.nilfiskcfm.com_vacuum-2Dfiltration_HEPA-2Dvacuum-2Dfilter.aspx&d=AwIFaQ&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=CLFZJ3fvGSmDp7xK1dNZfh6uGV_h-8NVlo3fXNoRNzI&m=Gwlz1WWzyiQO7AHw8dUUQNlF2HwbHdh86pSyVk7zJoU&s=gAeoFrW2SnY7RUwziiilDRYCluF7ynCCN60HnlgiPHU&e= 

 also remember that "HEPA/ULPA filter are only as good as its gasketing and
framing when installed and because all HEPA filters are used in critical
applications, in-place HEPA filter testing should be mandatory."
An important reminder of the many HEPA advertised low-end vacuums that do
not have good fittings/gaskets/silicone rubbers or framing in their built,
this makes the filter to be loose and all particles are expelled between
the smallest of gaps.


Hope this helps
