Filters for home use

Small filters for residential ventilation applications constitute a filter group with many varying designs and appearances. In this case, low pressure drop over the filter is of particular importance because smaller ventilation units often have weak pressure frames. Low pressure drop and/or frequent filter replacement are essential if they are to provide the air exchange for which they are dimensioned. Replacements are especially important in those instances where unit upgrades to fine filters in classes M5-F7 are concerned.
