◆ What is an invisible mask?
Before understanding this, it is necessary to understand what is a contact lens?
Before the 1960s, apart from the first hand-held glasses (which we often see in Western movies), people only knew that glasses could only be worn on the nose, otherwise they couldn't be called glasses, and who would have thought that they could be worn on the eyeballs? Until 1960, when the first pair of soft contact lenses were introduced, there was a fundamental change in this concept, which is when the glasses on the eyeballs were born, followed by Dr. Len, Haichang, and so on, we are now familiar with those brands.
But most people find it hard to accept the idea of putting something on their eyeballs, because it's definitely not comfortable, and safety is also a factor that we consider more, but it's really beautiful and convenient, and it's based on these two points that after two or three decades of spreading, people are slowly starting to accept it.
Now, looking back, not only are more and more people wearing them, but their function has gone beyond restoring eyesight. Many young people, even if the vision of both eyes are normal, but also still wear it every day, because it is no longer simply glasses, the look has become colorful, and at the same time I do not know who also gave it a nice name called "pupil", as if wearing it is equal to the beauty of the same journey, wear it, you can make you look more beautiful.
Invisible masks are also a reason with contact lenses, but it is no longer the mouth and nose full cover up, but a middle with a filter into the nostrils of the small nose plugs, through the closed mouth only nasal breathing, so that the air filtered through the filter and then enter the lungs, so as to achieve the purpose of purifying the air to protect the respiratory system. It is small and soft, into the nostrils, not to look around, stand far away from it is not easy to find, so it is known as the "invisible" mask.
◆ Invisible masks are small, but what about filtration?
The filtration effect depends on the quality of the filter in the invisible mask. A good filter can not only filter PM2.5, but also filter dust, pollen, flotsam, car exhaust, second-hand smoke, and so on, and even rhinitis and respiratory allergies have a very good protective effect. But there is one thing we must pay attention to when choosing, is that the invisible mask must not choose the activated carbon filter, because activated carbon is only on the toxicity and odor adsorption effect, and can not filter PM2.5, and the most critical is the invisible mask is put into the nostrils, inhalation needs to close the mouth tightly and only use the nose to breathe, which was originally the need for the mouth and nose and the pressure of the nose, and the pressure of the airflow when inhaling the nose, and the pressure of the nose. The pressure of the airflow will also increase when inhaling, if the filter layer is activated carbon, it is easy to inhale the activated carbon particles directly into the lungs during the inhalation process causing secondary damage. Therefore, I personally do not recommend the use of activated carbon as a stealth mask filter material, if consumers just want to filter the flavor, it is best to choose a conventional activated carbon mask, because that way of breathing is the mouth and nose and the nostrils away from the activated carbon layer is farther away from the nostrils, not like the stealth mask directly into the nostrils, so only from the filtering of the flavor of the level of the conventional activated carbon mask is more secure.
◆ After wearing an invisible mask, is breathing as smooth as with a regular mask?
Strictly speaking, the breathing of the invisible mask is not as smooth as the conventional mask. Because the conventional mask is the mouth and nose and used to breathe, while the invisible mask can only use the nose, otherwise the role of the mask is lost. But whether you use the nose or nose and mouth, as long as you can ensure the normal supply of oxygen and filter out the harmful substances in the air, their effect is the same. I remember reading a report that a professional doctor said that N95 masks can not be worn normally for more than 15 minutes, otherwise it will have an effect on the body. What does it mean? It means that wearing it you have difficulty breathing! Use people will say, I put on after breathing is not difficult ah, quite smooth, that can only mean that your mask filtration effect is not up to standard. Normal filtration effect is the filter material in the equipment air through the test results, that is closed, the reality is that there are a few people wearing a mask is and face is 100% closed? Once the seal is not tight, the filtration effect will be greatly reduced, no matter how good its original filtration effect, if you can still breathe well, it can only mean that the leakage of air. Anyone with a good seal should have difficulty breathing or the filtration will suffer.
The filter material is good or bad at the same time determines the filtering effect. Protection and permeability which are two contrary theories, not at the same time to reach the top, the better the protection, the worse the permeability, and vice versa. This is common sense, do not listen to others to fool his product protection and good breathable and strong, it is impossible. Good products are only in ......
Invisible mask washed can still be used available a few times
The key is certified? How effective?
At present, dust masks are using the principle of electrostatic adsorption to protect against dust, so the dust mask filter cotton can not be washed.
If it is a dusty working environment, it is still recommended to choose a regular dust mask.
Dust masks as special labor protection supplies, must be GB2626-2006 certification.
1, for dust and oily particles, protective masks are divided into anti-oil (oil smoke, oil mist, dust, smoke, fog, microorganisms, expressed in KP), anti-dust (dust, smoke, fog, microorganisms). For dust protection, there are three levels of protection: KN100, KN95 and KN90. They represent ≥99.97%, >95% and >90% protection against ultra-fine dust, respectively.
2, masks are divided into disposable, replaceable cotton filter half mask, full face mask. For long-term occupational protection, it is recommended to use replaceable cotton half mask.
3, the mask material has silicone, plastic, etc. Silicone material is relatively soft and comfortable, low facial pressure.
4, the mask according to the national standard size, which is particularly important. A lot of masks are not divided into sizes, the effect will vary from person to person.
5, masks cover the mouth and nose and cover the mouth, nose, jaw 2 kinds, of which the second type of contact mask large, close better, low pressure.
Never neglect respiratory protection, the use of counterfeit, gauze, towels, etc. as masks, easy to lead to lung disease. Some of the current common N100 level dust masks, the use of electrostatic adsorption principle, in order to ensure that the protective effect at the same time, breathing smoothly.

Invisible masks need to be cleaned? How many times do I have to change it? Thank you
Wear masks to pay attention to matters: (1) before wearing the mask, as well as before and after taking off the mask must wash their hands; (2) to make the mask close to the face: (1) the mask has a color side outward, with a metal piece of the side of the upward; (2) tighten the rope to fix the mask, or put the mask's rubber bands around the ears, so that the mask is close to the face; (3) masks should be completely covered with the mouth, nose and chin; (4) the mask on the metal piece along the sides of the bridge of the nose, and the mask is a good idea. (iv) Press the metal tabs on the mask tightly along the sides of the bridge of the nose to make the mask fit tightly on the face. (3) Avoid touching the mask after wearing it to prevent the protective effect from being reduced; if you must touch the mask, wash your hands thoroughly before and after touching it. (4) When taking off the mask, avoid touching the outward part of the mask as much as possible, because this part may have been contaminated with germs. (5) After removing the mask, wrap it in tape or a paper bag and dispose of it in a covered garbage can. (6) Replace the mask at least once a day. Replace the mask immediately if it is torn or soiled.

How often should we change the mask? Or how should we rate the replacement of masks?
In the usual field of industrial dust control, we recommend that customers in the process of use, if they find that their breathing begins to become difficult, inhalation becomes strained and load-bearing, it means that the mask needs to be replaced, because the filter holes of the mask filter paper has been stuffed with dust and particulate matter. This is one of the more important criteria and methods for replacing and judging anti-particulate masks. Of course, if you feel your mask is too dirty, or damaged, or due to sweat and exhaled water vapor too much can also be replaced.
Many masks are used in quarantine and epidemic prevention, medical treatment, anti-bacterial and anti-virus, how often do we change the mask?
Because of the contagiousness of the virus, and the ability of the current influenza A (H1N1) virus to spread. I recommend that mask users replace a mask every time they take it off when conditions allow.
The correct way to wear a mask and precautions are as follows.
I. Thickness of the mask:
Experts recommend wearing 12-16 layers of masks, if you wear too thick masks will feel suffocated, especially for a long time to wear the nasal mucosa becomes fragile, the loss of the original physiological function of the nasal cavity. Then wear too thick masks, masks are difficult to close the nose, losing the significance of protection.
II. The size of the mask:
Some people think that the bigger the mask, the better, covering the nose and mouth there is a surplus. In fact, such a mask does not play a role in filtering the effect of harmful substances, because harmful substances encountered in the air will be inhaled through the face and the mask between the slit. The hygiene requirements of wearing a mask, wearing a mask should be able to cover the nose and mouth and most of the area below the eye socket. If the mask is too large or too small, germs. Dust. Dirt is easy to enter from the edge of the mask or the gap between the two, will affect the filtering effect of the mask.
III. Mask health requirements:
The mask is in direct contact with the oral and nasal cavity, so its health is particularly important. Masks inside and outside the two sides can not be used alternately, otherwise the outer layer of contaminated dirt directly close to the face when inhaled into the human body and become a source of infection, in addition, the mask is not wearing, should be close to the mouth and nose side of the folded, into a clean plastic bag for spare parts, and prohibited randomly stuffed into a pocket or hanging on the neck.
Fourth. Cleaning masks pay attention to, first with boiling water for 5 minutes, and then scrub with soap, clean water after hanging to the hot sun, of course, after more than 10 minutes in the wash, in order to prevent wear and tear of cotton yarn, it is best to choose a new mask! It is best to wash in a timely manner every day, or buy a disposable, because the oral respiratory germs are easy to breed in the mask. After washing, it is best to put in the sun.
Has anyone used the invisible mask, good? That kind of good?
Not very good
Invisible masks which brand is the best
Ordinary qualified masks are generally colorless masks, the material is made of gauze and non-woven fabrics, without any chemical treatment, no odor, and breathability and filtration are very good, so it is safer and cleaner. Fashionable color masks are mostly made of chemical fiber fabrics, patterns and colors are also made of dyes, there may be *** smell, some color masks inside and outside the color is different, coupled with poor air permeability. Although the use of beautiful, but there are certain health risks. Guo Ruoxiheng suggests that when buying masks, it is best to go to a regular hospital or drugstore to buy, do not buy at some roadside stalls, or buy only a fashionable look, while ignoring the function of the mask itself. It is recommended to choose branded masks, such as 3M PuraVation JD/USA Noss Honeywell and so on.
Invisible nose plug mask
Invisible mask, similar to the nose plug, a section of the bracket attached to the ends of the fiber filters, the two ends into the nostrils can play a role.
This invisible mask does not cover the mouth, it is more like two small nose plugs, wear only need to be plugged into the nostrils can be, after which the activated carbon will be able to automatically isolate the dust, and does not affect normal breathing. This traffic police wear on both to prevent inhalation of dust, but also whistle shouting. 2013 February, the Shanghai Traffic Police Headquarters issued to the districts and counties of the first-line traffic police and coordinators, as duty equipment. Because of the fear of nasal congestion so that the police uncomfortable on duty, now only trial invisible masks, whether or not it will be fully promoted to wait for the feedback submitted to the General Assembly to make a final decision.
Clothing workshop with invisible masks which will work better
There is no one invisible dust mask can effectively prevent the lungs from receiving dust hazards. Clothing workshop, if not properly protected, can lead to cotton-dust lung or lung inflammation.
In the day-to-day, it is common that some enterprises should be issued dust masks to the issue of currency, or to provide gauze masks, low-grade dust masks, resulting in the occurrence of pneumoconiosis. According to the relevant provisions, the enterprise has the responsibility to protect the workers body occupational health, dispensing protective gear and supervise the daily good protection work. Dust environment is to provide dust masks.
Do a good job of daily protection, in addition to taking wet, closed, ventilated or so, it is recommended to wear dust masks certified by the national standard to prevent the occurrence of pneumoconiosis.
Scientific selection of dust masks can prevent pneumoconiosis through the following ways.
1, dust masks as special labor protection supplies, must be certified by GB2626-2006.
2, the mask is divided into disposable, replaceable cotton filter half mask, full face mask. Long-term occupational protection use, it is recommended to use replaceable cotton half mask.
3, the mask material has silicone, plastic, etc. Silicone material is relatively soft and comfortable, low facial pressure.
4, the protection level of N100, N95 and N90 three levels, because most of the dust on the human hazard heavy, it is recommended to choose N100 level.
5, the mask according to the national standard size, which is particularly important. A lot of masks are not divided into size, the effect will vary from person to person.
Never neglect respiratory protection, the use of counterfeit, gauze, towels, etc. as a mask is used. At present, the incidence of pneumoconiosis, to the family and personal suffering is not worth the loss.
