I see no upside to not changing the filter at every oil change, other than cost. I buy in bulk, so cost really isn't that big a deal to me. Some will claim Earths resources, etc. That's fine. Everyone has to decide on their own what's important to them.
As I already mentioned, another benefit is that it makes the oil change less messy if you’re not changing the filter and it shaves off some time as well.
