Synthamax Air Filters do not require oil. Ser­vice air filter as needed by cleaning with com­mon non-petroleum all-purpose household
cleaner and water. Simple Green®, Formula
409® or equivalent works great. Apply cleaner
to outside of air filter and allow to soak. Then
flush filter clean from the inside out with a gar­den hose and repeat steps if necessary. Do not
apply high pressure water or air to clean filter.
Allow filter to air dry and reinstall.
