A wastepaper (WP)-based cylindrical hollow air filter (CHAF) is prepared by oxidative heat treatment of WP fragments, followed by vacuum filtration of a WP solution to form a WP column that underwent boring. The CHAF shows excellent PM2.5 removal efficiency (99.12%) and an extremely low pressure drop (4 Pa) at a flow rate of 1.5 m/s because of the structural and chemical characteristics of the CHAF. CHAFs that are connected in series and parallel demonstrate the advantages of an increased removal efficiency and a decreased pressure drop, respectively. Thus, combinations of CHAFs connected in series and parallel further increase the PM2.5 removal efficiency and decrease the pressure drop at a high PM2.5 concentration of 644,000 μg/m3 and a high flow rate of 5–10 m/s. The CHAFs are also able to simultaneously remove particulate matter (PM) and formaldehyde (HCHO) at very low concentration levels (below 0.1 ppm). A miniature air cleaner equipped with the CHAF can effectively remove 5 L of PM2.5 at extremely high concentrations of over 650,000 μg/m3 and a high flow rate of 5 m/s with a high efficiency (99.24–96.88%), low pressure drop (31–34 Pa), and short removal time (3.5 min) for up to 270 cycles.

基于废纸的圆柱形空心空气过滤器模块，用于去除颗粒物（PM 10和PM 2.5）和HCHO
通过对WP碎片进行氧化热处理，然后真空过滤WP溶液以形成经过镗孔的WP柱，可以制备基于废纸（WP）的圆筒形空心空气过滤器（CHAF）。由于CHAF的结构和化学特性，它在1.5 m / s的流速下显示出优异的PM 2.5去除效率（99.12％）和极低的压降（4 Pa）。串联和并联连接的CHAF分别具有提高去除效率和降低压降的优势。因此，串联和并联连接的CHAF的组合进一步提高了PM 2.5的去除效率，并降低了高PM 2.5浓度为644,000μg/ m 3时的压降。流速为5-10 m / s。CHAF还能够以非常低的浓度水平（低于0.1 ppm）同时去除颗粒物（PM）和甲醛（HCHO）。配备CHAF的微型空气滤清器可以有效去除5 L PM PM 2.5，其超高浓度超过650,000μg / m 3，流速为5 m / s，效率高（99.24–96.88％），低压降压（31–34 Pa），去除时间短（3.5分钟），最多270个循环。
