<p class="MsoNormal"><span style="mso-bookmark:_MailEndCompose"><span style="font-family:"Arial",sans-serif;color:black">We did not design air showers into the gowning room at KAUST’s Nanofab. Data taken in the 1990s through the 2000s indicated that air showers
stir up particles from both street clothing and from street clothing under cleanroom garments, particularly dacron polyester cleanroom garments with conductive fibers woven into them. We have found that laminar downflow Class 100 (high to full HEPA coverage
at 80 fpm) creates a downward sweep of particles shed by people and their clothing that is much more effective than air showers.
<o:p></o:p></span></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailEndCompose"><span style="font-family:"Arial",sans-serif;color:black">Pausing at the stages of gowning to allow this “air washing” of particles to the floor should be part of the gowning process.
<o:p></o:p></span></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailEndCompose"><span style="font-family:"Arial",sans-serif;color:black">This is the concept behind the original design and construction of the KAUST nanofab gowning room from 2008 through 2011.<o:p></o:p></span></span></p>
