Rated 5.0 out of 5.0 by Best I have ever had!!!!!!!!!!!!!!!!!!!!!!!! This filter is the most outstanding filter I have ever used. It has been 5 years since we bought it, the only reason we needed to get a new one was because I tipped it on its side to clean out the blades. The filter filled with gas and oil...................not very smart huh? June 12, 2010
