There are several filters but only a few companies that actually make them.The best thing to do is decide which filter(s) you are interested in and then ask about them.
The top makers of filters are in no certain order:
1.Affinia/WIX-They make WIX,Affinia,NAPA Gold,Carquest Blue,Auto Value and many other name filters.WIX makes house brand filters for other companies.
2.Champion Laboratories-They make Super Tech,Mobil 1,Champ,Luber-Finer,Mopar(Some),Kleener,Imperial,E-Core,STP,TRD,MXM,K&N,Petro Clear,Deutsch,VW,Motorcraft(New vehicle only),Royal Purple Service Champ to name a few.They make house brand filters for other,
3.Bosch/Purolator-Bosch,Purolator,Mopar(Some),Motorvator(K-Mart brand),Motorcraft(aftermarket),and others.They also make house brand filters for others.
4.Fram-Fram,Honda(OEM Filter) and they did make Pennzoil filters,not sure if that still applies.There may be others.
Most filters made will fall under one of these companies.The filters will have varying degrees of construction depending on the price point and who they are made for.
There are others but these are probably the top manufacturers.
