This is an inquiry message about Air Filter for Bathroom Fan in the 108th China Canton Fair. (这是一条买家关于"Air Filter for Bathroom Fan"的询盘信息，来自第108届中国广交会。)Inquiry Message (询盘信息) Air Filter for Bathroom Fan Hello, I need to replace a couple of filters in our bathrooms, we just moved in. The old filters say ""D-Mark"" but there is no model number. It is 7.5 inches X 7 inches with a whole in the upper part so that the face of the fan can fit on it. Do you sell something like this? If so, I would like to buy about 10 of them.
