Are n99 Masks Washable?

Protective Equipment (PPE) is vital for everyone. We use them in construction, the medical field, and various other industries. The n99 masks 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 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. You should consider the quality, type, number, and frequency of filters that your N99 face mask will use. Carbon filters filter out bacteria, viruses, and chemicals the best. 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. 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 N99 masks are an environmentally friendly and economical option, but they have a higher up-front 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. Ideally, you only use them once, and only you. 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. 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. Before being worn again, every mask must be inspected for damage or degrading and a seal checked. A group of doctors, scientists, and other professionals formed a group called N95DECON to research and test different sanitizing methods for face masks. These methods have been thoroughly researched but have not yet been tested extensively.

VAPOROUS HYDROGEN PEROXIDE

This kills both resistant bacteria spores as well as 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. However, the UV light can break down the straps and face pieces, and it can be challenging to expose the lower layers to the radiation. High UV light doses can cause the mask to be brittle.

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 effective method to sanitize facemasks, as heating them at 60 degrees C and 80% humidity does not seem to damage their filtration capabilities.

Steam and Liquid Hydrogen Peroxide

The CDC also tested steam sterilization of masks with liquid hydrogen peroxide and steam. They used steam bags in low-powered microwaves to kill bacteria without damaging the face mask up to three times. They found that the N99 respirator could be soaked in 6% liquid hydrogen peroxide for 30 minutes, which did not affect its filtration. However, they did not test the fit afterward. Avoid using soapy water when sterilizing N99-face masks. It can degrade the masks’ materials and affect their ability to filter small particles correctly. Do not use alcohol or bleach. This can affect the mask’s ability efficiently to filter toxic substances. 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 is a safety leader and only offers products that have been thoroughly researched and field-tested.
