N95 masks can be disinfected with steam: study

Steam sterilisation could be done twice safely without altering fit, researchers say

US researchers have tested the option of disinfecting and reusing disposable N95 masks, concluding the masks can be safely disinfected with steam.

The design of the N95 mask presents challenges when it comes to disinfection, Texas researchers say in a letter, published in Infection Control & Hospital Epidemiology.

Other research has shown that washing with water decreases mask performance by 21%, while sanitising with alcohol reduces performance by 37% and results in mask shrinkage.
