These filters work and they work great. Compared to many similar spec filters I've bought from local stores, the performance here is simply outstanding. Store-bought filters tend to significantly block airflow in my oven system, causing air to be drawn in around the filter, which is kind of counterintuitive. However, these filters simply work. They let enough air through so my oven doesn't get stressed and they don't seem to lose airflow when dust builds up. My particular home environment is very dusty and I chose to change these filters monthly simply because they inevitably become contaminated with dust, but I could probably extend it to up to two months (perhaps longer) if the need arose. Nothing more to say, honestly. I think a filter is good if it doesn't cause me any problems and lasts as long as I expect. I seriously doubt I'll be buying any other filters in the near future.
