Thanks for the response! To make sure I understand this correctly: If I find a product labeled as &quot;HEPA&quot; (w&#x2F;o a prefix or suffix such as &quot;type,&quot; &quot;like&quot;, &quot;style,&quot; and &quot;99%&quot;) then I can be assured that the product does meet the standard of removing 99.97% of particles that have a size of 0.3 µm?
