The Momentum HD Pro 10R Replacement Air Filter is an OILED10 layers of progressively finer mesh cotton gauze/synthetic media between 100% polyurethane top and base. We recommend that you follow the manufactures recommended service schedule. You can find that in your vehicle owner’s manual. Once you reach that mileage mark, take a look at the filter. If you can still see the aluminum mesh on the filter then it is still ok and does not need to be cleaned. Check the filter every other oil change. When it gets to the point where you cannot see the aluminum mesh on the filter anymore, then it is time to clean the filter. You should clean the filter around the 25K - 30K mile mark under normal conditions. In extreme dusty or dirty environments, you should check more frequently. Over cleaning the filter will shorten the life of the filter and reduce its filtration efficiency. Accumulating some dirt actually helps the filtration.
*Important Reminder - If you can still see the aluminum mesh on the outside of the filter, it is still fine. Clean the filter when you cannot see the aluminum mesh on the outside of the filter.
