In article 1702139 , Xia Yin, Bin Ding, and co‐workers create a free‐standing nanofiber/nets air filter assembled with two‐dimensional nanonets (≈20 nm) and bonded nanofibers by combining an electrospinning/netting technique and peel off process from designed substrates. Due to small pore size, high porosity, and free‐standing capacity, the ultrathin filter can achieve a removal efficiency of >99.00%, light transmittance of ≈70% for PM1 filtration, and >99.970% removal for PM0.3 filtration.
