First of all, these are not the same filters as in the picture (see photo). They create too much pressure drop and the oven cycles on and off every 10 minutes. The HVAC company explained that the oven gets too hot due to insufficient airflow, so it shuts off for a moment and cools down a bit, then starts up again. It's not very energy efficient
