A perfect replacement for the expensive and hard to find paper filters. This is the second one I bought. The first one is also the same model No.but for a different mower. After one year of weekly service, the filter is clean and non restrictive. Unlike the paper and foam cover unit, which would have been replaced 2 times during the season and the paper element was plugged, causing the mower to run rich. One of these is equal to 2 years worth of filters and I have cleaned the filter and oiled it and had it back running in a hour.
