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
