This G7 replacement panel filter is designed for use with the Airmiq inline filter box. The pleated filter media captures airborne dust, lint and other particulate matter from supply or extract air, helping improve system cleanliness and protect fans, coils and ductwork from contamination. Its high surface area provides useful dust-holding capacity while allowing air to pass with controlled resistance. Regular inspection and replacement help maintain ventilation performance; the required service interval will depend on air quality, system operating hours and the pressure drop across the filter.
