Review on 🔥 Valterra A10-3361VP Rotating/Fixed Vane Heating and A/C Register- 5" ID, Beige - Efficient Airflow Control for Optimal Comfort by William Mathis

After a long search I finally found this. I didn't have a part number so it was pure luck as even the Amazon search didn't turn up one. I found it among the companions of another vent. The filter block itself matches my current ones in my 2016 Tiffin Allegro 32SA Open Road RV. Collar shorter than mine by 7/8 inch. My collar is 1-3/4 inches. Since Valterra doesn't appear to make this size, it's possible that Tiffin modified or custom made it. What I can't find are replacement filters. If anyone has found them, I would be grateful for a tip. All I can find are 5.25 inches with a hole in the middle, which are slightly smaller (they are closer to 5.5 inches). If Valterra has stopped making these devices please let me know as I would like to have stock while they are available. Thank you for reading!
