Stir-fries with whatever veggies and protein I have on hand are my go-to. Just chop some broccoli, carrots, chicken or tofu, throw in soy sauce, and cook in one pan for 15 minutes. They reheat fine and keep me full without crashing.
I have this exact model and ran into the same worry when the foam frame looked different. The new HEPA was the XHF350 rectangle and it did fit my NV352 once I removed the thin felt ring that stayed behind from the last filter. My grille measured about 5.3 by 4.6 inside and the new filter with gasket was near 1.2 thick. I thought it was wrong and almost sent it back but then I pressed the door closed and it molded in after a day. Works great.
