I hate to be just a copy and paster but this is pretty clear. I would give it a cleaning and put it back in. I like to use the vacuum method with my household vacuum and the soft brush attachment. Just be careful not to damage the media.
Cleaning
EaA filters should be cleaned every year or 25,000 miles, whichever comes first. Carefully remove the filter from the housing. Clean the housing with a shop towel, being careful not to knock contaminants into the air inlet. Filters can be cleaned by carefully vacuuming the filter media on the dirty side, or by holding the filter with one hand and carefully blowing the filter media at a 45 degree angle on the clean side using low-pressure shop air (15-20 lbs. psi).
Service Life
AMSOIL Ea Air Filters are guaranteed for four years or 100,000 miles, whichever comes first. The guarantee applies only if the filter has been serviced according to AMSOIL recommendations. In off-road, frequently dusty or other severe duty applications, clean and change more often as determined by operating conditions or as indicated by restriction gauge.
