Synthamax Air Filters do not require oil.
Service air filter as needed by cleaning with
common non-petroleum all-purpose house-
hold cleaner and water. Simple Green®,
Formula 409® or equivalent works great.
Apply cleaner to outside of air filter and al-
low to soak. Then flush filter clean from the
inside out with a garden hose and repeat
steps if necessary. Do not apply high pres-
sure water or air to clean filter. Allow filter
to air dry and reinstall.
For your Oiled media filter we
suggest using the AIRAID Filter
Tune-Up Kit!
