Yes. Google parts for the model name you have.

"Can I remove the filter? Clean it? Change it?"

It depends on the model. For example, the Whirlpool WMH53521HZ has a charcoal filter which must be changed as described in the User Guide (page 5). The GE JVM3160RFSS has washable filters on the underside of the oven but also has charcoal filters that must be replaced if installed in recirculating mode as described in the Use and Care Manual.

@Sheila Isenberg, you'll get a much better on-target answer if you cite the brand and model of the microwave involved ...

On my Bosch, I remove the filter very easily and clean it. It just slides out.

IMO if it is an OTR MW it has removeable filters and if not get anew hood and a counter MW
