<div>Hi Antoine,</div><div>Did you have to up size the fan or are you on lung power only? I will put a charcoal filter on just because it seems practical and it is pretty cheap.</div><div>What did you use for the filter?</div><div>Hank</div><div><br></div>

<div><div><div>Hi Hank<div>I have installed one on the intake hose of the scrubber. With a dedicated cannister.
