For your Oiled media filter

we suggest using the AIRAID

Filter Tune-Up Kit!

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.
