What Are N99 Masks?

N99 masks or a - is a specific type of face-covering to filter what the user is breathing in. N99 Mask is a face-covering designed to filter the air that is being inhaled. These masks have two principal defining characteristics: N99 Masks form a tight seal against your face so that when you breathe in, the airflow coming in and out of your nose and mouth passes through the filtration material without leaking from the mask’s edges. N99 mask materials should be capable of capturing at least 99% particles from the user’s nose and mouth while they breathe. These characteristics mean that, unlike ordinary cave coverings, the N99 respirator seals tightly and has a high filtration capacity.

What to Consider When Buying an N99 Mask

N99 masks offer the best protection by filtering out 99.9% of airborne particles. However, they don’t all provide equal protection. The mask’s useful life is dependent upon its filters, which are the most important element of any efficient face mask. Consider the quality, type, and number of filters that your N99 mask will use. Carbon filters have the highest efficiency in filtering out viruses, bacteria, and chemicals. N99 masks that have breathing valves or micro ventilators make it easier to talk and breathe. N99 masks are available in a variety of sizes. Make sure that you have enough coverage for your nose, mouth, and chin. A face mask that doesn’t fit properly is essentially useless.

If you engage in lots of physical activity or already have breathing difficulties, you can find N99 masks with two breathing valves to help you breathe easier.

Extending the Use of N99 Masks

N99 masks are disposable filtering respirators. It is best only to use one mask per day. Your N99 mask should be thrown away if it is contaminated with dangerous particles or becomes dirty throughout the day. But, during times where many people are wearing respirators and masks throughout the day, the CDC has put out information on how to sterilize N99 masks. Although they do not recommend that you reuse masks, you can sterilize N99 masks for reuse in an emergency.

These are the requirements for safe sterilization of an N99 mask washable:

The mask must remain effective against COVID-19. The sterilization must not affect the filtration capabilities. It must not have an impact on the fit of the user’s face. The mask must still be safe for the user.

These methods of decontamination are not recommended for N99 Masks:

Ethylene Oxide causes concerns for off-gassing. Ionizing Radiation can degrade filter performance. The use of microwaves can melt the respirator near metal components and compromise the fit. Autoclaves, high temperatures, and steam can cause filter degradation.

Sterilizing N99 Masks for Reuse

Three methods are showing the most potential to decontaminate N99 masks: using moist heat, vaporous hydrogen peroxide, or exposing the masks to UV radiation. Every mask should be checked for damage and passed a seal-check before it is worn again. A group of doctors, scientists, and other professionals formed a group called N95DECON to research and test different sanitizing methods for face masks. While these methods have been researched thoroughly, they have not gone through extensive testing yet.

VAPOROUS HYDROGEN PEROXIDE

This method kills resistant bacteria spores and viruses. 3M has used this method for fixing masks up 20 times without any degradation. But, when sterilized at higher doses, the filters become less effective. The machines to perform sanitizing are dangerous and require extensive training for the operator.

UV RADIATION

Using UV radiation stops the viruses related to coronavirus without affecting the masks filtering ability for 10-20 sterilizations. The UV radiation can cause damage to straps and facepieces and make it challenging to expose lower layers to the radiation. The mask’s material can be damaged by high doses of UV light.

Heat and Humidity

Heating N99 masks at 60-75 degrees C for half an hour can stop viruses related to COVID-19, but it has not been tested on the coronavirus itself.This is an excellent way to clean facemasks. They can be heated at 60 degrees C with 80% humidity.

Steam and Liquid Hydrogen Peroxide

The CDC also tested sterilizing the masks using steam and liquid hydrogen peroxide. To kill bacteria, they used steam bags in low-power microwaves. The mask was not damaged more than three times. They also noted that soaking an N99 respirator in 6% liquid hydrogen peroxide for half an hour didn’t affect filtration, but they did not test fit integrity afterward. Do not use soapy water to sterilize N99 masks. This can cause damage to the mask’s materials and reduce its ability to filter small particles. Do not use alcohol or bleach. This can affect the mask’s ability efficiently to filter toxic substances. It’s safe to assume it’s clean from overnight storage. The coronavirus can live for up to three days on some materials. It is crucial to purchase washable N99 masks from a trusted source. Bielcor, a safety industry leader, only sells products that have been field-tested and thoroughly researched.
