Can N95 Mask Be Reused? How Often Replaced

The most talked-about topic amongst your group of friends has to be the outbreak of coronavirus. For the average person, the most critical aspect would be the adoption of "scientific prevention" procedures, which include strictly minimizing the frequency of outdoor activities, and wearing masks whenever outside, followed by proper hand washing after returning home. One of the most important prevention measures that demand consistent emphasis is the correct way of "wearing a mask." Nowadays, masks are not easy to find, and it becomes crucial to know how to wear masks in a safer and more practical manner. Also, it is equally essential to know when to change your mask. So, let us delve more into the "mask" and adhere to scientific procedures.

One type of mask that is widely used is the Protectional Reliable Mask. There are other common masks available as well, but if you prioritize safety and protection, the Protectional Reliable Mask is the one you should choose.

The world is full of various masks, including everyday cotton and linen masks, as well as disposable medical surgical masks and medical protective masks like the N95 mask.

In order to protect yourself from the "new coronavirus pneumonia", it is recommended to wear either a "medical surgical mask" or a "medical protective mask".

The typical "Medical surgical masks" follow a three-layer structure, consisting of the waterproof layer, the filter layer and the comfort layer, with the innermost layer being a non-woven fabric. These masks are effective in preventing respiratory infections, however they are not designed to block out "haze" substances.

Medical protective masks and N95 masks have proven to be effective in protecting against droplet infections caused by body fluids or blood splashes from patients. As per the NIOSH standard, the filtration efficiency of N95 masks reaches 95%. Compared to medical surgical masks, medical protective masks provide better seal and protection. Hence, in terms of effectiveness, N95 protective masks without breathing valves are recommended for better protection during sexual activity.

During this "special period", it is advised against the use of "regular cotton and linen masks" including cotton masks, gauze masks, canvas masks etc. Such masks lack the necessary materials to provide complete protection against infection. The primary objective of wearing masks should not be hindered by inadequate masks.

How often do masks need to be replaced?

It is important to note that wearing masks for extended periods is not required for the general public. Consistently wearing medical masks can increase nasal sensitivity and even impair the natural physiological functions of the nasal passages, which can affect one's immunity. It is unnecessary to wear masks at home or in well-ventilated areas with low population density.
