Description

This is a foam pre-filter that is used to help prevent dust, pollen, and other debris from clogging the air filters of small engines. One of the most common problems faced by small engines is an inadequate air supply caused by air filters that have become mired with airborne debris. Cleaning or replacing filters can become a tiresome and expensive proposition. If filters are not adequately cared for, they perform poorly, waste gasoline, pollute the air, and cause internal engine damage. A good way to help an air filter do its job is by adding a foam pre-filter in the air filter compartment. Pre-filters are exposed to all the things that clog air intakes, so periodically, they also must be replaced. Foam pre-filters are designed to fit snugly inside the housing of the air filter of virtually all small engine housings. To install a pre-filter, remove the air filter housing by taking off the one screw holding it in place. Remove the air filter from the housing and place the pre-filter inside against the exterior wall of the housing with the arrows pointing up. Reinstall the air filter. The paper of the filter should fit perfectly against the labeled side of the pre-filter. Now simply reattach the air filter housing. Genuine Midwest Engine makes this OEM replacement part, and it is sold separately.
