Above that temperature, the polymer fibers begin to soften, melt, or release, compromising filter integrity and creating potential downstream contamination. Glass microfiber media has none of those failure modes — it stays structurally intact at 500°F continuous operation. The trade-off is cost (microfiberglass costs more to produce than synthetic) and slightly higher pressure drop, which is why Koch reserves the HT line for genuinely high-temperature applications and recommends synthetic-media filters everywhere else.\u003c\/p\u003e\u003ch3\u003eMulti-Pleat HT vs. Multi-Pleat Elite\/XL8\/GT: temperature ratings compared\u003c\/h3\u003e\u003cp\u003eAll Koch Multi-Pleat panel filters carry MERV 8 ratings, but their continuous-temperature tolerances differ dramatically:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Pleat Elite, XL8, GT:\u003c\/strong\u003e Synthetic media, beverage board frame — rated to roughly 200°F continuous (the standard for general HVAC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Pleat HT (this filter):\u003c\/strong\u003e Glass microfiber media, aluminized steel frame — rated to \u003cstrong\u003e500°F continuous\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIf your application stays below 200°F at all times, the synthetic-media filters are a better economic choice.
