Filter Design Guide - bndhep.net

It is hard to find a 1% accurate capacitor, but a 1% accurate resistor costs only a few cents. If we want to change the filter function, we just buy new resistors. With the help of our Filter Tool, we can try out different resistor values and see what the response will look like. The result is a compact and versatile filter with a precise response.

So 200 ft 3 /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= 1.7m 3 /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(340m 3 /h) of air at a static pressure of 1.2"(300Pa).
