In article number 1603306 Bin Ding and co‐workers fabricate a cleanable air filter that transfers moisture and effectively captures PM2.5. The air filter was fabricated via electrospinning using super‐hydrophilic PAN fibers as the adsorption‐desorption vectors for moisture‐vapor and hydrophobic PVDF fibers as the repellent components. A hydrophobic to super‐hydrophilic gradient structure provides a high PM2.5 purification efficiency, low air resistance, and an important moisture‐vapor transmission rate (MVTR).
