Many laboratories use biosafety cabinets to limit contamination risks for sensitive and susceptible experiments. Biosafety cabinets rely on HEPA filters to remove contaminants from intake air in order to create a controlled environment for experimental manipulation. HEPA filters come with particle size thresholds, so particles smaller than that threshold will not be removed. Researchers have therefore speculated that aerosolized DNA may elude HEPA filters.
