Hi Leslie,
<div><br>
<div>As I mentioned in my earlier email, the impact may not be as severe as your nose thinks it is. Your pre-filters may possibly be in dire straights, but the CR envelope may be okay. Please click the following link and read the paper.</div>

<p class="MsoNormal"><span style="color:#1F497D">I’m very sorry to hear of your misfortune.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">First and foremost we would recommend replacing the filters on your air handler – you may have already done that, and a thorough cleaning of the air handler including the coils and even down to the fan blades.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Internal to the lab – downstream of the air handler, suggest you some of your HEPA filters in the cleanroom. In my limited experience with smoke contamination, those filters will need to be replaced, but if
you can inspect a few for damage (discoloration of the media), and also test a sample of the media. At that point you will have a better idea of the level of contamination between the air handler and the final filters – and that may drive you to inspect and/or
clean that ductwork. Without knowing the material that burned, you are faced with the insidious nature of smoke that “sticks” to everyplace it is exposed. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Lastly, within the cleanroom proper you may want to do a thorough cleaning including HEPA vacuum then wipe down of all walls, ceilings, floor and tool surfaces with an IPA/water solution (sometimes called a “super
clean”).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The labnework community is full of folks with great experience and I’m sure you’ll get additional suggestions.<o:p></o:p></span></p>
