Panel Pre Air Filte Ventilation System AC Furnace Clean House Paper Frame G1 G2 G3 G4 Folding
Efficiency:
The filtration efficiency of pre filter is G3 or G4, corresponding to 90% of the weight method and 40% of the colorimetric method. These filters are usually used for primary filtration of air conditioning and ventilation systems, and also suitable for simple device of air ventilation systems.
Replaceable:
Users can easily replace the filter to reduce the trouble of transportation and storage.
