Aerosol filtration efficiency of household materials for homemade face masks: Influence of material properties, particle size, particle electrical charge, face velocity, and leaks

Frank Drewnick et al.

Summary: The COVID-19 pandemic has led to widespread use of face masks worldwide. Testing 44 samples of household materials and medical masks for filtration efficiencies and pressure drops across different particle sizes revealed significant variations between materials and particle sizes. Electrostatic attraction plays a strong role in overall filtration efficiency for particles up to 100 nm in diameter.

Variability of the penetration of particles through facemasks

Buddhi Pushpawela et al.

Summary: Wearing masks is crucial in preventing the spread of COVID-19. N95 masks consistently showed the lowest particle penetration rate, while KN95 masks and cloth masks allowed higher penetration rates. There is considerable variability in the performance of different types of masks, leading to uncertainty in the level of protection they provide.

Inward and outward effectiveness of cloth masks, a surgical mask, and a face shield

Jin Pan et al.

Summary: The study found that vacuum bags performed the best in terms of filtration efficiency, while thin acrylic and face shields performed the worst. The fit of the mask is crucial for both inward and outward protection efficiency. A recommendation is made for a three-layer mask for optimal filtration efficiency.

Filtration efficiency, breathability, and reusability of improvised materials for face masks

Morteza H. Bagheri et al.

Summary: The study aimed to evaluate filtration efficiency and breathability of different mask materials, as well as their reusability. Cotton and sterilization wraps showed good filtration efficiency, while dry baby wipes performed well but degraded quickly. Polypropylene electrostatic HVAC filters had the best filtration efficiency but were not recommended due to risks. Combining cotton with sterilization wraps or using dry baby wipes can significantly improve filtration efficiency with added pressure drop.

A highly efficient cloth facemask design

Christopher D. Cappa et al.

Summary: Increasing the mouth-mask separation distance enhances mask filtration efficiency for expiratory aerosols, with a new reusable cloth mask design achieving over 93% filtering efficiency for both exhaled aerosols and inhaled ambient aerosols. The design also allows for air exchange between the mask deadspace and the environment, limiting CO2 buildup and maintaining ambient O2 levels.

Homemade facemasks: particle filtration, breathability, fit, and other performance characteristics

Susan R. Reutman et al.

Summary: Homemade cloth masks and other improvised face coverings have limited particle filtration performance compared to high-end commercial surgical/medical masks or NIOSH-certified N95 filtering facepieces. A three-layer facemask prototype was designed using the best performing materials, with washing decreasing its collection efficiency but maintaining breathability. It is important to note that homemade masks offer some level of protection, but should not be expected to provide the same level of respiratory protection as professional masks.

Efficacy of homemade face masks against human coughs: Insights on penetration, atomization, and aerosolization of cough droplets

Bal Krishan et al.

Summary: The study found that larger droplets expelled during coughing can penetrate single-layer cloth masks, forming smaller daughter droplets and increasing infection potential. Two essential criteria for droplet penetration through mask layers have been suggested, along with a new parameter to characterize penetration potential and droplet size. The frequency of mask washing also has an effect on the outcomes.
