Not ALL air returns have filters because mine doesn't and never has . The filter goes on the furnace or the airconditioner. This is perfect for a change up . I'm thinking it would have to be removable but then I haven't removed mine in years . I clean them in place.

Doesn't it have to be removed to change the filter? Don't all air return vents have filters? Looks pretty but seems very impractical.
