Hi Range Hood Filters Inc, and thank you for taking my phone order. I can tell that you love what you do! I’m so grateful to find my Thermador filter! As I told you, mine is so gnarly it won’t stay in place and despite my trying everything to soak it in degreaser, scrub it with suds and use a pressure washer; nothing can de-gunk over 20 years of bacon grease and other lovely deposits! I looked all over the Theramdor site to no avail–nobody seemed to have anything longer than 18″. As they say in Cally “You The Man!” And how great to know that someone out there is living the dream~! I look forward to receiving the new filter–ah the little things in life! 🙂 Have a lovely weekend, and thanks again for the personal service.
