Measure from edge to edge in inches, rounding up to the nearest inch for each measurement. For example, if your measurements are 19.5″ x 24.5″ x 0.75″, your filter size would be 20″ x 25″ x 1″.
CFM = Length x Width x Height x (Air Changes per Hour) / 60 min. Calculating the CFM is measuring the air volume velocity and it is a relatively simple calculation. You need to know the length, width and height (measured in feet) of the given space as well as how many air changes per hour are required.
Filters can be broadly categorized by their function (e.g., low-pass, high-pass, band-pass, band-stop) and by their construction (e.g., mechanical, absorption, membrane, active, passive). Electronic filters manipulate frequencies to pass or reject them, while mechanical and physical filters separate particles based on size or chemical properties.
