Aluminum or wood hepa different?
    #19268772 - 12/12/13 11:59 PM (10 years, 1 month ago)

Does it matter if the HEPA filter is built with an aluminum or wood case?

Also, the depth of the filter only correlates to the size blower that I would need correct (e.g. 5.25" depth would need less cfm and a smaller blower than a filter that has a 12" depth which would need a larger blower)?

Thanks again everyone for your help

see "Match a blower to the filter"

Quote:

1. Find out the area of your filter by multiplying the width and the hight in feet (for instance the smallest reasonably usable filter would be 2ft x 1ft)
2ft x 1ft = 2 ft2
2. Multiply the required air speed(the one Stamets specifies, 100 ft/min) with the area of your filter
100 ft/min x 2 ft2 = 200 ft3/min
So 200 ft3/min(= cfm = "cubic feet per minute") is the amount of air your blower must deliver at the sum of the STATIC PRESSURE of the HEPA filter + prefilter.
NOTE: 1 cfm= 1.7m3/h
So if you use the above filter with 1"(250Pa) static pressure and a furnace prefilter with a static pressure of 0.2"(50Pa) your blower must deliver 200 cfm(340m3/h) of air at a static pressure of 1.2"(300Pa).






also, no real difference no real difference concerning housing of filter, still preferr alu personally
