I have been using the hydro-gear filters as I could get them for less than $10 a piece. Went to place an order for them and I read the specs at 10 micron. Exmark calls for a 25 micron bi-directional filter. The only filter I could find with these specs is the Exmark filter. These cost $35 at all the local dealers. I can get them for $23.xx plus shipping online. What do you guys think of running the 10 micron when the manufacture calls for a 25 micron? FWIW I ordered the Exmark filter.
