"2 Use the compressed air to remove the dirt from the other side of dirty side."
"4 Allow cleaner to soak into both sides of air filer for 10 minutes; afterward use the compressed air to remove dirt and cleaner. (Repeat step 3 and step 4 until all spots of dirt are cleaned.)"

hmm.. i don't have compressed air machine to wash this.

are there any alternative method to wash the filter? i'm thinking of buying for Axia since KNN is not available.

Can i hv the quotation of the cleansing kit and air filter for works.
