3. RINSE Rinse the filter with warm water, clean side to dirty side to flush out the dirt. 4. DRYING Allow the filter to dry naturally. Try to avoid heat because it might shrink the cotton. If you use an air gun, do not blow closer than 30cm from the air filter and do it carefully, otherwise the air flow will generate holes 5. -
