Add to BasketInquirePrimary filter sponge, a filter sponse with alternate blue and white, is mainly applicable to collecting the larger dust molecules in the air to prevent the medium filter from being filled and blocked with larger dusts so early and to keep longer service life and better filtration effect. It is made of super hard fiber and is sprayed with a kind of adhensive evenly for strengthening, and so it has a better primary filtration.
