AB  - Similar to most air filtration strategies, fibrous filters have the trade-off between efficiency and air flow. An electrostatic-assisted electret filter may help improve filtration efficiency while maintaining air flow. In this work, we present a silk-nanofiber-modified polyethylene terephthalate (SNF@PET) fiber filter with an improved compression strength and modulus by 1.9 and 1.6 times respectively, at 2 wt % SNF content, increasing the structural stability of the filter to support a higher air flow. The filtration efficiencies of the SNF@PET fiber membrane for PM<inf>0.3-0.5</inf> and PM<inf>0.5-1</inf> are up to 99.7% and 99.6%, respectively, with a corresponding pressure drop of 3.3 Pa at 0.1 m s<sup>−1</sup> air velocity. The SNF@PET fiber filter showed a slight decrease in filtration efficiency to 98.3% for PM<inf>0.3-0.5</inf> and a small increase of pressure drop to 3.7 Pa (from 3.3 Pa) after 400 h.
