Inquiry (采购产品): home air outlet What is the best way to add a HEPA air filter to the various room outlets instead of trying to use the very inefficient furnace filters that we all know and love to replace? I am trying to invent something that will be more efficient than the furnance filter to eliminate my allergic reactions. What materials can I find. Do I have to cut to size or use tape or what?
