Review on 🌬️ Honeywell Home 4-inch High Efficiency Air Cleaner Filter, MERV 12 Rated, (CF200A1008), 16 x 25 x 4 3/8 by Pete Brown

Fits in my oven with no problems. I've seen multiple reviews for multiple brands for a 4 inch filter that was never wide enough. I haven't had this problem. And I think that the higher cost of the MERV purchased compared to what was in place when the house was purchased had a huge impact on air quality and the need for dust removal. I think they are rated to last 4 months or more but we replace the filters every 3 months. I think most HVAC specialists recommend every 3 months so that's what we do.
