Note! Humidity of the mask affects the protective effect, how often should I change the mask?

In fact, for us, when the mask is wet, it does breed mold, and it will also cause the surface to be burdened with dust particles and foreign matter, so this is because it will reduce the protective effectTherefore, it is necessary to replace it in time, and it is normal for us to choose disposable masks as much as possible, and for other masks, try not to choose more than two days, so we can think about the problem from the following aspects

1. Moisture of the mask will lead to the breeding of mold or small particles of Fudan dust on the surface, that is, because this will seriously affect the protective effect, so it should be replaced in time if conditions permit. In fact, it has to be said that after the mask is wet, it will lead to mold on the surface of the mask, and on the other hand, it may cause the surface to be contaminated with fine dust particles and foreign bodies, and it is precisely because of this that the protective effect will be seriously reduced. <>

2. Under normal circumstances, the common masks on the market are disposable masks, so the quality is relatively uneven, try to choose disposable use to avoid potential risks to yourself. In fact, it has to be said that the common disposable masks on the market are often of uneven quality, and it is precisely because of this that for safety reasons, try to choose disposable use, and for us, some masks may have huge defects in quality, so long-term use may also bring potential risks, so for safety reasons, it should be replaced in time. <>

3. Under normal circumstances, try not to use the mask for more than one day, if conditions permit, try to choose a disposable mask to wear and replace it with a new mask in time, so that you can better protect yourself. In fact, it has to be said that considering the complex environment of using masks in daily life, it is precisely because of this that if there is a phenomenon of indirect use many times, then try not to choose more than one day at this time, and for us, it is likely that it will also be contaminated with other foreign bodies in the process, which will affect the protective effect, so if conditions permit, try to choose to wear disposable masks and replace them in time to avoid unnecessary risks to your own safety.

Under normal circumstances, after the mask is wet, it will lead to mold and microscopic dust particles on the surface, which will affect the protective effect, and for other types of masks, try to use it according to the recommended length of use instructions, and do timely cleaning and disinfection.

Moisture of the mask will affect the protective effect, if it is usually changed once a day, it does not hurt, during the epidemic period at most once every 3 hours, to ensure the protective effect.

In this regard, experts said that the mask mainly relies on electrostatic force to adsorb virus aerosols after moisture, and its electrostatic effect disappears to have the desired protective effect, so once the mask is wet, it is recommended to replace it as soon as possible, if necessary, bring 2 to 3 more clean masks into public places and crowded areas, if the mask is wet, be sure to replace the mask.

We all buy disposable masks now, so the masks should be changed every day so that the protective effect can be achieved.

The masks we wear should actually be changed every day, because the mask plays a role in defending against viruses, and many viruses are already attached to the mask at the end of the day.

Generally speaking, it is best to change it every time you use it. Because the electrostatic adsorption virus effect of the mask disappears when the mask is wet, bacteria may also grow in a humid environment.

How often to change the mask.

Different types of masks have different lifespans, including medical disposable masks, professional N95 masks, and anti-smog masks, all of which have different lifespans.

Disposable masks: It is recommended to replace them every 4 hours, disposable masks are more common masks, do not reuse disposable masks, generally should be replaced once every 4 hours.

Cotton masks: It is also known as gauze masks in the industry, and it is recommended to wash them in time every day for this type of mask.

Anti-mask: Generally, it needs to be changed for 2 days. Professional protective masks such as N99 and N95 masks should be replaced with new ones after two days of use, otherwise they will not be able to play a good protective role.

Replaceable filter masks: This type of mask generally changes the filter once every 8-10 days, and the mask body is recommended to be cleaned every 2-3 days. This kind of mask is inserted on the inside of the ordinary mask with the function of dustproof, anti-germ and other functions, the filter is generally disposable, the general wearing time is 8 to 10 days, if there is a stain on the filter should be replaced immediately.

If it is a disposable mask, it will take about four hours to change, and if it is a mask, it is best to wash and change it once a day, the protective effect will be better, and it will also be more conducive to physical health.

4 hours is the best time, and it is important to keep the mask dry during these 4 hours.

It is best to change it every hour, because it will give your mask a better protection.

For general surgical masks, the best time to replace them is once a day. Don't use the mask because it looks clean, it will filter a lot of dust and germs that are invisible to the naked eye, and it will be very dirty after wearing, so replace the mask with a new one in time.

Medical masks should generally be replaced when worn 4 times in a row. However, if there is contamination or the mask is wet, it should be replaced in time to avoid infection or no preventive effect.

It is best to change disposable masks every 5 hours, because during this time the mask will become wet, which will greatly reduce the protective effect of the mask, and it is also very hygienic to change the mask during this time.

I think it should be replaced within 4-8 hours so that it can better protect against the virus.

It's best to change your mask every two hours, because after two hours some bacteria will grow.

It is better to change the mask every 6 hours, which is more hygienic and conducive to protection.

Generally, it should be replaced in time every 4 hours, and this can also achieve the effect of preventing and controlling the virus.

If it is polluted, it will be replaced. There is no specific time for this, as long as you have removed the mask from your face, it will be contaminated, and it should be changed.

If you wear it, change it once every half a day, and if you don't use it, it's best to change it once a month, so as to ensure that the protective measures of the mask are better.

It is usually replaced every 4 hours.

It is recommended to replace it in a timely manner according to the length of use.

If the mask is contaminated, wet, or damaged, it needs to be replaced immediately.

In terms of protective capacity, it is recommended that different groups of people choose suitable masks according to the specific working environment.

Different masks:

1. Disposable medical masks:

Ordinary medical masks implement the recommended standard of the pharmaceutical industry YY T0969-2013 "Disposable Medical Masks", and the protection level of such masks is low.

Application: This type of mask is recommended for use by the public in non-crowded places and should be changed every 4 hours.

2. Medical surgical masks:

The medical surgical mask implements the mandatory standard YY0469-2011 "Technical Requirements for Medical Surgical Masks" in the pharmaceutical industry, and the protection level is medium. 30% filtration efficiency for non-oily particles and 95% efficiency for bacteria.

Application: During the epidemic period, it is suitable for use in dense places such as buses, taxi drivers, sanitation workers, airports, railway stations and other places, and is replaced every 4 hours.

3. KN95 mask:

It mainly implements the standards of GB 2626-2006 "Respiratory Protective Equipment - Self-priming Filtering Anti-particulate Respirators" and GB T 32610-2016 "Technical Specifications for Daily Protective Masks".

In the GB 2626-2006 standard, masks for preventing particulate matter are divided into KN for filtering non-oily particles and KP for filtering oily and non-oily particles.

In the GB T 32610-2016 standard, the masks are divided into - grades, of which the filtration efficiency masks fully meet the KN95 standard, in addition, all medical protective masks also meet the KN95 standard.

4. N95 mask:

In fact, there is no such thing as N95 in the Chinese standard, N95 is derived from the Niosh CFR 42-84 standard for ordinary protective masks in the United States, and N95 stands for 95% filtration efficiency for non-oily particles, which is the same as KN95.

5. FFP2 mask:

In accordance with the European EN 149-2001 standard, FFP2 stands for 94% filtration efficiency for oily and non-oily particles, which is basically the same as N95 KN95.

Application: N95 KN95 FFP2 mask is suitable for on-site exploration, sampling, and testing personnel. According to the instructions or every 6-8h, it is not recommended to wear an N95 KN95 FFP2 mask with a breathing valve.

1. Under normal circumstances, there is no problem in using disposable masks that meet the standards for two or three times. This situation mainly refers to the fact that in most life scenarios such as non-medical institutions and non-epidemic areas, such masks can be used two or three times, "but it is not recommended to use them n times".

2. When we go to medical institutions to see a doctor or visit a patient, or in an epidemic area, a densely populated place, such as a station and other places, then the masks used in these environments cannot be reused, and must be used once in accordance with the use standards. Because these places are places where there is a lot of virus, masks are easy to carry viruses, and if they are used repeatedly, they can easily cause infection.

Masks are divided into medical masks and ordinary masks, ordinary masks usually need to be replaced within 4 hours, and medical masks are generally replaced within 6-8 hours. It is recommended to replace it in a timely manner according to the length of use.

Wearing a mask for a long time has a more direct impact on breathing, and for people who have poor cardiopulmonary function, wearing a mask is undoubtedly a tormenting thing. When going up the stairs, shopping for groceries, and cleaning, there will be breathlessness, chest tightness, and difficulty breathing, and the consequences are also more serious. If you already have this kind of problem when wearing a mask, it is better to find a place with good ventilation, remove the mask, and breathe in the air for a while.

If you wear a mask all the time, your face will also be deformed, which will have an impact on your face. The steel wire and string on the mask have the pressure on the **, just like the underwear will be marked after being worn for a long time, and the same is true for the mask. Some people wear masks for a long time and still feel a slight pain in their ears, which is for this reason.
