Make sure no air is flowing from the area near your eyes or from the sides of the mask. It is important to check that it fitssnugly over your nose, mouth, and chin.
They proposed a decontamination method using ozone to inactivate SARS-CoV-2. Thus, they performed different experiments in two ozone decontamination boxes. Based on this, they proposed practical recommendations to implement a simple disinfection box system using inexpensive and readily available components that could be used for FFP respirators. The ozone concentrations required are 10–20 ppm with an exposure for at least 10 min. They noted that it is an improvised solution for situations of need such as the COVID-19 pandemic, but not an optimal long-term solution. Therefore, governments, manufacturers, scientists or experts in the field are working towards finding the most effective method for disinfecting FFP respirators against COVID-19.
He says this is the mask he wore to wait in line for hours to get a PCR test during the Omicron wave. This beak-shaped style of the mask has also become popular with restaurant workers because of how comfortable it is for long periods of time.

This is a process based on applying heat and humidity to the FFP respirators. There are different studies that address this method for the disinfection of FFP Disposable masks respirators (3M, 2020b, Bergman et al., 2010, Bergman et al., 2011, Heimbuch et al., 2011, Lore et al., 2012, Viscusi et al., 2011). Among them, the study carried out by 3M is the only one that specifically focuses on the inactivation of SARS-COV-2. They used an environment chamber and introduced each FFP respirator in a high temperature self-seal pouch.
They’re made from three layers of fabric and have an adjustable nose strip. The masks are available in Blue and Black, and you can order as few as 10 masks to over 1,000.

You can purchase CandyCare’s disposable face masks in packs of 25 to 2,000.
Regarding decontamination of FFP respirators by ozone, Zhang et al. studied the inactivation of the SARS-CoV-1 by applying different concentrations of ozone solution disinfectant. They found that this virus could be inactivated using a high concentration of 27.73 mg/L for 4 min. Dennis et al. conducted another study where they analyzed the scientific literature available in this regard and concluded that the existing findings in other studies seem to support that ozone inactivates viruses by attacking capsid proteins.
That said, it’s safest, and just good hygiene, to handle your masks with care, touching only the elastics and washing your hands afterward. After you’re vaccinated, you can more safely return to doing activities that you might not have been able to do because of the pandemic.
