Are n99 Masks Washable?
Face masks and respirators are essential Personal Protection Equipment (PPE). We use them in construction, the medical field, and various other industries. The n99 mask is used to filter out harmful particles and prevent the spread and contraction of infectious diseases. The n99mask 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. Two main characteristics of these masks are: 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 features mean that the N99 respirator is more durable than other cave covers and has a higher filtration rate.
What to Consider When Buying an N99 Mask
N99 masks provide the most protection, filtering out 99% of airborne particles, but that doesn’t mean they are all equal. Filters are essential for any mask to last a long time. Consider the quality, type, and number of filters that your N99 mask will use. Carbon filters filter out bacteria, viruses, and chemicals the best. N99 Masks with micro-ventilators or breathing valves make breathing and speaking easier. N99 masks come in various sizes; ensure that the one you choose covers your entire mouth, nose, and chin. A face mask that doesn’t fit properly is essentially useless. Buy certified N99 masks; you want to use one that’s of the highest quality possible.Reusable 99 masks can be an economical and environmentally-friendly option. However, they come at a higher upfront cost. 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
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. 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. While they don’t recommend that you reuse masks unless, in an emergency situation, you can sterilize your N99 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. Before being worn again, every mask must be inspected for damage or degrading and a seal checked. To test and explore different methods of cleaning face masks, a group of scientists, doctors, and other professionals created N95DECON. 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. Operators must be trained in the use of these machines.
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. High doses of UV light can break down the material of the mask itself.
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. The researchers also found that N99 respirators were not affected by a half-hour soak in 6% liquid hydroperoxide. However, they didn’t test the fit of the masks 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. Use alcohol or bleach; this affects the mask’s ability to filter harmful materials efficiently. Consider it clean after overnight storage. Certain materials can withstand the coronavirus for three to five days. 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.
