Protective Equipment (PPE) is vital for everyone. These devices are essential for construction, medicine, and many other industries. The n99mask is used to filter out harmful particles and prevent the spread and contraction of infectious diseases. The n99 are the most effective face-covering option available, but many people want to know what to look for when purchasing one and if they can wash and reuse them.
What Are N99 Masks?
N99 masks or a n99 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 share two main 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% of 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. Think about the type, quality, and number of filters your N99 mask will use. Carbon filters are the most efficient at filtering out viruses, bacteria, and chemicals. N99 masks that have breathing valves or micro ventilators make it easier to talk and breathe. N99 masks come in various sizes; ensure that the one you choose covers your entire mouth, nose, and chin. An unfit face mask is useless. Use certified N99 masks.Reusable 99 masks can be an economical and environmentally-friendly option. However, they come at a higher upfront cost. For those who are physically active or suffer from breathing problems, N99 masks come with two valves that allow them to breathe more easily.
Extending the Use of N99 Masks
N99 masks are disposable filtering respirators. You should only use them once and only once. Discard your N99 mask whenever it becomes contaminated or exposed to dangerous particles throughout the day. However, in an era where so many people use respirators and masks all day, the CDC has provided information on how to sterilize N99 face masks. They don’t recommend you reuse masks except in an emergency. However, you can sterilize your N99 face mask for reuse.
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
The three most powerful methods to disinfect N99 Masks are moist heat (vaporous hydrogen peroxide), UV radiation, and using moisture. Note that every mask should get inspected for damage or degradation and pass a seal check before being 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 up to 20 times to clean masks without any degradation. However, if sterilized with higher amounts, filters lose their effectiveness. Sanitizing machines can be dangerous and require extensive training.
UV Radiation
The UV radiation kills coronavirus viruses without affecting the ability of the masks to filter out 10-20 sterilizations. UV radiation can damage the face pieces and straps, so it is possible to expose the lower layers of 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. They used steam bags in low-powered microwaves to kill bacteria without damaging the face mask up to 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. When sterilizing N99 face masks, do not: Use soapy water; this degrades the masks’ materials and impacts their ability to filter small particles properly. Use alcohol or bleach; this affects the mask’s ability to filter harmful materials efficiently. Assume it’s clean after overnight storage; the coronavirus can survive for three or more days on certain materials. High-quality respirators should only be bought from trusted sources when purchasing an N99 mask washer. Bielcor, a safety industry leader, only sells products that have been field-tested and thoroughly researched.
