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.
