Comparison of DNA Extraction Protocols for Air Filters

A study comparing DNA recovery from two filter materials (AirPrep™ and Corncobology H10 HEPA) using two extraction kits (QIAamp and PrepFiler™). The dataset, authored by Emily Bibbo and last updated in May 2026, includes results from filters loaded with saliva or touch DNA deposits. The findings highlight interactions between filter structure and extraction chemistry.

Use Cases

• Benchmarking DNA extraction kit performance based on comparisons between PrepFiler and QIAamp protocols.
• Evaluating filter material efficacy for trace DNA collection based on results from AirPrep and HEPA filters.
• Optimizing forensic laboratory workflows for automation and contamination control based on noted advantages of the PrepFiler kit.
• Investigating the influence of surface roughness on DNA deposition and recovery based on findings related to filter structure.

Strengths

• Directly compares two established forensic DNA extraction kits (PrepFiler and QIAamp).
• Evaluates two distinct filter materials (AirPrep and HEPA) for air sampling.
• Includes within-filter comparisons using quarter-sized sections for controlled analysis.
• Dataset is openly licensed under CC-BY-4.0 for reuse.

Limitations

• Dataset is a 75.5 KB DOCX file, suggesting limited raw data or a text-based report rather than a structured dataset.
• Column-level documentation and sample data are unavailable, requiring manual inspection after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
