What was done
The authors conducted a systematic review across PubMed, Scopus, and Web of Science to evaluate the performance of biodegradable electrospun nanofibrous membranes for capturing airborne sub-micron particles. Extracted data included structural properties and key filtration performance metrics: filtration efficiency, pressure drop, and quality factor.
What was found
The abstract reports no numerical values (such as specific filtration efficiencies, pressure drops, or quality factors). Qualitatively, the review identified that among biodegradable polymer electrospun membranes, polyvinyl alcohol (PVA)-based membranes were the most effective for capturing sub-micron particles while maintaining low energy consumption.
Why it matters
This review highlights PVA-based biodegradable nanofibrous membranes as promising eco-friendly alternatives to non-degradable synthetic air filters, reducing post-use environmental waste.
Limits
The abstract does not state the number of included studies, specific search dates, inclusion criteria, or quantitative performance data. Real-world durability, shelf life, moisture sensitivity, and performance under variable ambient conditions are not reported in the abstract.
