Note - the following is an example, only for the largest size of filter. I can also assist with all other sizes though. How powerful should my fan be for this filter. Long answer: it depends if you add a pre-filter to your project, and what the resistance of that filter is. This will determine the fan velocity needed to reach 70-110 feet per minute coming from the face of the filter, as per iso cleanroom standards. This item is made of aluminum and pleated cellulose.
