The folding type natural gas filter element is provided with a first axis, and the filter element comprises a plurality of folding units which are distributed around the first axis and are integrally formed; the folding unit comprises a first filtering layer; the second filter layer is formed on the first filter layer and is relatively close to the first axis side; the third filter layer is formed on the first filter layer and is relatively far away from the first axis side; in a non-filtering state, the second filtering layer and the third filtering layer can maintain that a first included angle with an opening facing the first axis is formed on one side, relatively close to the first axis, in each folding unit; a second included angle with an opening far away from the first axis is formed between every two adjacent folding units; in a filtering state, the second filtering layer and the third filtering layer can maintain the first included angle within a first preset range, and can maintain the second includ
