Do you need to change filters on your gas fireplace?

It depends on the type of gas fireplace you have. Most gas fireplaces do not require filters, but some models may have filters that need to be changed periodically. If your gas fireplace has a filter, it will typically be located near the air intake or exhaust vent. The owner's manual for your gas fireplace should specify whether or not it has a filter and how to change it. If you are unsure whether or not your gas fireplace has a filter, it is best to consult with a qualified technician.
