We purchase ceiling air vent filters from the Tampa RV show from a vendor - white plastic with a white filter - once we added a paper ring to them because the taped wouldn't hold them up we really liked them and wanted to buy more - we didn't keep the original packaging and no information on the filter - does anyone have that information ? - I checked the web and it's blank on this item. I'd appreciate that info if you know how to contact them - thank you
