SIGNS ITS TIME TO REPLACE YOUR N95
N95 masks can be reused multiple times as long as you follow the recommended guidelines for doing so.
Is the shape consistent?
When the mask gets scrunched up, holes form between the mask and your skin, limiting the mask's ability to protect you against infections. As a result, the mask's ability to maintain its shape is critical.
Do not use your respirator past its shelf life, typically 3 to 5 years from date of manufacture.
The expiration date is printed on the package. Respirators should be stored according to the manufacturer's specifications, which include temperatures of no less than -4°F (-20°C), no more than 86°F (30°C), and a relative humidity of less than 80%.
Limit the usage to 2-3 days
The duration of time a mask is worn is more crucial than how many times its being worn. Using the same mask to run to the grocery store, for example, is very different than wearing it all day at work. In general, the use of a N95 mask should be limited to two to three days. Because they can't be washed, they should be discarded once they're no longer useful.
Does the mask feel moist?
If the mask becomes somewhat moist, it can still be used as long as it dries out and fits snugly on your skin. However, if it is too damp (due to sweat or rain), it is time to replace it because once wet, it loses its ability to keep its shape. It's also a good idea to switch masks if you start to notice a strange odor.
Moisture, even from your breath, slowly damages the mask, and this process will be accelerated if you're wearing it to the gym or in a humid room or region. You can reuse your mask if it has become moist due to condensation from breathing. Keeping those paper bags in a dry place (preferably near a sunny window) will aid in viral deactivation.
It is crucial to consider certain factors while using N95 masks. An N95 mask cannot be washed, rinsed or disinfected. Getting the mask wet or agitating the mask with soap or any chemical can harm the material, losing its properties.
It is recommended to not attempt disinfect your mask with hydrogen peroxide or other chemicals, eventually reducing its filtration efficiency, including bleach or any other disinfectant. These chemicals remain on the mask and can be harmful for breathing as it remains on the respirator.
