Yellow 3 3/4" x 6" Foam Pre Filter. This pre filter fits over a standard filter and prevents dust and debris from entering the main filter.

Each filter is sold as pictured, and comes ready to install. We do recommend oiling this pre-filter for best performance. 

Note that this filter features a closed end to fit completely over another filter.
