do you change oil filters anytime you change the oil?

ABSOLUTELY! There is almost a quarter of a gallon of dirty used oil inside the filter, just waiting a cold day morning when you are rushing to work, thus the cold oil increases its viscosity several times from the cold, and the fast turning engine pumps the filter contents around the pressure relief valve directly into the fresly changed oil !!! ALWAYS CHANGE THE FILTER TOGETHER WITH THE OIL CHANGE, each and every time.

Also, some particulates can get through an old filter(like metal particulates) that can damage your engine, that's mostly in a "worst case scenario" though.

You don't have to, but it is greatly suggested especially as waste particulates in the filter can slow oil flow which will reduce the efficiency of the sump system. Not only that but you will be running clean new oil through a nasty old dirty filter... it's like washing with new fluid but an old dirty rag.

You should always 'wet' the rubber ring on the inside of the new oil filter with fresh oil before installing it. This helps maintain the life of the rubber o-ring and prevents leaks. I like the surgical gloves, have to get me some of those :).
