A long-shelf life activated carbon includes activated carbon impregnated with salts of copper, zinc, and molybdenum, and TEDA, wherein the activated carbon is also impregnated with phosphate. The phosphate may be supplied from any source, and in particular from sodium or potassium phosphates. The phosphate may be impregnated before or after the aforementioned salts. The phosphate prevents aging of the activated carbon against gases such as cyanogen chloride, as demonstrated with experiments conducted under conditions of both open accelerated aging and closed accelerated aging. The long-shelf life activated carbon may be included in an air filter.
