The Difference Between Surgical Masks And KN95 Masks

The difference between surgical masks and n95 masks

The n95 type mask can achieve 95% filtering effect after testing, and the effect of protecting PM2.5 should be the best. But for n95 masks, doctors do not recommend ordinary people to wear them. In theory, the more closed the protective material of the mask, the better the effect of blocking particles. Conversely, the more closed the mask, the harder it is to breathe. Poor wearing may also cause dizziness due to lack of oxygen. Wearing professional protective masks such as n95 is prone to cause breathing difficulties, especially for patients with cardiovascular diseases.

Medical surgical masks are generally used in high-demand environments such as medical clinics, laboratories, and operating rooms, and are masks worn by medical staff when working. The safety factor is relatively high, and the resistance to bacteria and viruses is strong. Medical surgical masks can also be used to prevent the spread of influenza and respiratory diseases.

What is n95 protective mask

The n95 mask is one of the 9 particulate protective masks certified by the National Institute of Occupational Safety and Health. "N" means not resistant to oil. "95" means that when exposed to a specified number of special test particles, the particle concentration in the mask is more than 95% lower than the particle concentration outside the mask. The 95% value is not the average value, but the minimum value. n95 is not a specific product name, as long as it meets the n95 standard, and the products that pass the review can be called "N95 masks".

Can n95 masks be antivirus

If there are 95 two numbers, it means that the protective ability of this mask is above 95%. That is to say, for the minute substances larger than 0.3 microns, the defense ability of this mask is more than 95%, and it can block the minute substances larger than 0.3 microns outside the mask. Microbes such as viruses and bacteria are generally larger than 0.7 microns, so n95 masks can effectively protect against viruses.

How often does the medical n95 mask change

The n95 mask can theoretically be used for 1 to 2 days and can be reused. But in fact, due to the different environment and dust concentration of the user, the use time of each population mask is also different, so the service life of the n95 mask is also different. If you are outdoors or in a crowded area for a long time, generally speaking, n95 masks have to be replaced for four to six hours.

The n95 mask is not suitable for wearing for a long time due to its good sealing performance, which makes it easy for people to have trouble breathing and lack of oxygen. When it is found that any part of the anti-particulate mask is damaged, and the respiratory resistance is obviously increased, the entire mask should be discarded immediately.
