How to Choose the Right Face Mask

Medical face masks are suitable for surgeons, because it can protect doctors from pathogens during surgery. So, in the period of coronavirus and flu, how should we choose the best face mask to protect from coronavirus?


Medical surgical mask

If you have been to a dentist,surgical masks will look familiar-they will be used by doctor and nurse to prevent liquids from splashing. The main purpose of surgical masks is to prevent infected people from sneezing or coughing liquid from entering your mouth or nose. If you are in close contact with someone who is ill, wearing a medical mask can protect the doctor and also prevent the disease from spreading to others.

Can Kn95 reduce the spread of viruses?

The rapid spread of COVID-19 around the world has made us pay more attention to various preventive measures. Make sure to wash your hands frequently, minimize outdoor activities. You must wear a mask when you go out. The outbreak of the epidemic also caused people to doubt the masks. Many people want to know whether the kn95 mask can prevent viruses?

According to the requirements of GB2626 standard, KN standard masks are classified again according to their filtering performance for non-oily particles. We are already familiar with the three masks KN90, KN95 and KN100. The KN95 mask refers to a filtration efficiency of greater than 95% for non-oily particles above 0.075 microns, and the diameter of the new coronavirus COVID-19 is about 0.1 to 0.12 microns. Therefore, wearing a KN95 mask can effectively prevent viruses.


However, here is that qualified masks that meet all the standards of GB2626 have no anti-penetration requirements. The biggest difference between it and medical mask. Medical surgical masks have anti-permeability requirements, and the outermost layer is a waterproof layer. Therefore, care must be taken to avoid patient droplets and saliva in order to prevent the mask from getting wet and increasing the permeability of the virus.

Choose a mask with or without a breathing valve?

No breathing valve mask: two-way breathing protection. Whether it is inhaled or exhaled, it must be filtered by the mask.

Mask with one-way breathing valve: the wearer can only protect himself.


Which of KF94 mask and N95 mask is better?

Since KF94 is not aimed at medical standards, there is no relevant bacterial filtration rate standard in the production process. In addition, the external materials are the same as the non-medical KN95 and N95 masks. Water resistance is not as good as medical masks. Once the droplets are contaminated,if the mask is not replaced for a long time, it will still increase the permeability of bacteria and viruses. Therefore, KF94 can play the role of personal protection, but its effect is inferior to KN95 protective masks.

Is the KF94 mask used only once?

As we all know, KN95 is the Chinese standard for protective masks, which refers to filtering non-oily particles with a diameter greater than 0.3% and greater than 95%. The KF94 mask was developed by Korea. According to the official website of the Korea Food and Drug Administration (MFDS), the standard mask has a filtration rate of more than 94% for particles with a diameter of 0.4 μm.

In other words, the KF94 standard mask can filter out at least 94% of particles with a diameter equal to 0.4 μm.

Therefore, the KF94 mask is not disposable, it is the same type of protective mask as the KN95 mask. If we are no direct contact with new coronavirus-infected people or endemic areas, etc., we can reuse the kf94 mask,but it can be reused up to 5 times.

How to Choose the Right Face Mask to Protect Yourself?

Outdoor activities, such as walking in the park, keep a distance of more than 2 meters with others

Working environment is well ventilated, indoor independent office


Disposable medical mask

Go to supermarkets, shopping malls, elevators and other crowded and sealed places

Gathering work

Medical surgical mask

A medical staff in the general outpatient department and general ward of the hospital

Medical staff in emergency department

Epidemic-related testing personnel

For those who closely on conducting epidemiological investigations

Medical protective masks or Disposable Protective Clothing for Medical Use

Medical staff

Confirming or suspecting a patient

Persons who conduct epidemiological investigations on confirmed and suspected cases

How to reuse the masks?

If you are faced with the shortage of masks, you can reuse the masks depending on the possibility of infection.

If there are the following situations, disposable masks should be discarded:

The mask is damaged and deformed;

The mask becomes wet or dirty;

Breathing becomes more difficult.

01 How to remove the mask?

If the mask you take off needs to be used again, you can hang it in a clean, dry and ventilated place or fold it in a clean and breathable paper bag,and ensure that it is stored separately.

02 Can medical masks be cleaned?

It cannot be disinfected with disinfectant, heating, etc.

Do not use alcohol spray or high temperature disinfection

Alcohol and high temperature will cause the outer material of the mask to degenerate to varying degrees, the ability to block droplets and saliva will decrease, and the protection of the mask will be greatly reduced.

03 Do not use UV light disinfection

The material of the filter layer of the mask is a thermoplastic polymer material, which is very sensitive to ultraviolet rays. After receiving ultraviolet radiation, the structure will be destroyed and the filtration performance will be reduced.

How to Protect Yourself from the Coronavirus

How to Protect Yourself from the Coronavirus

The American are suffering from an epidemic, the double pinch of influenza and coronavirus. You should protect yourself from coronavirus and flu outbreaks. How to use disinfectant products to fight coronavirus to prevent the body from being attacked by COVID-19? These coronaviruses fighting product list can help you.


Part 1: How to Clean and Disinfect the Workplace to Help Slow the Coronavirus Spread?

1. Choose the right disinfectant

Commonly used disinfectant products can be divided into 9 types according to their ingredients: chlorine-containing disinfectants, peroxide-based disinfectants, aldehyde-based disinfectants,alcohol-based disinfectants, iodine-containing disinfectants, phenol-based disinfectants, ethylene oxide, Biguanide disinfectant and quaternary ammonium disinfectant.

Disinfectants are dangerous chemicals and must be selected in strict accordance with the instructions. Excessive use will bring other risks. For example, peroxyacetic acid is a strong oxidant that can easily kill microorganisms. It is often used for disinfection of clothing,floors, walls, house spaces, etc. However, when the concentration is too high,it can irritate and damage the skin and corrode items.

2. Different disinfection methods

Commonly used are soaking,wiping, spraying, different objects and places need different disinfection methods.

Small objects (such as gloves,fabrics) can be soaked and disinfected with chlorine disinfectant.

Door handles, light switches,elevator buttons, desk tops, chair backs, mechanical buttons, production tools,etc. are in contact with many people. It is recommended to clean surface with chlorine disinfectant.

After shutting down the mobile phone, computer, etc., wipe it with a disinfectant wipe.

Large surfaces such as walls and floors, the spraying method is recommended to sterilize.

At the same time, please pay attention that the action time of the chlorine disinfectant agent is 15-30 minutes, and then wipe with water.

3. How to perform air disinfection in the work room?

For disinfection in offices and production sites, the preferred method is natural ventilation. Natural ventilation reduces the amount of indoor virus and dilutes its concentration to reduce the risk of disease.

4. How to do on the way to and from work?

  • Wear disposable medical mask properly. Try not to take public transportation, it is recommended to walk,ride or drive.
  • After arriving home, remove your mask and wash your hands first.
  • Wipe the mobile phone and keys with a sterile wipe or 75% alcohol.
  • Keep the room ventilated and to avoid crowds.


Part 2: Coronavirus Fighting Product List to Help Slow the COVID-19 Spread

According to the CDC and Prevention, washing hands with soap and water remains the best way to prevent the spread of the virus.

The new coronavirus is believed to be transmitted mainly by people and respiratory droplets, such as coughing,sneezing and spitting.

Some items on the list can help reduce the spread of COVID-19. Products containing bleach, alcohol or hydrogen peroxide are the best at killing off germs and virus. Each disinfection chemical has specific instructions. But the important tip is that once you have applied the cleaner to the surface, do not wipe it off immediately, save it for some time to kill the virus.

75% Alcohol

Alcohol is effective in killing germs and bacteria

1. You can dilute the alcohol with water, but you must keep the alcohol concentration around 70% to kill the coronavirus. Many hand sanitizers have an alcohol concentration of about 60%and Lysol has an alcohol content of about 80%. These are all effective against coronaviruses.

2. Try to wipe items with alcohol as much as possible without disinfection by spraying. Alcohol should not be used for large-scale disinfection, nor for laundry disinfection (clothes may generate static electricity).

3. Ensure good indoor ventilation before using alcohol disinfection. After disinfecting the surface of the object with alcohol, be sure to stay away from flames, such as smoking and electrical switches.


Chlorine Disinfectant

1. Chlorine-containing disinfectant refers to a disinfectant that dissolves in water to produce sodium hypochlorite.

2. The chlorine-containing disinfectant should be dissolved in water at about 20. The higher the water temperature, the worse disinfection effect. When diluting the disinfectant, keep the space well ventilated.

3. The disinfectant should be stored in a cool and ventilated place below 25.

UV disinfection lamp

The UV lamp is simple and convenient, and can sterilize in a room. However, if the UV lamp is not used properly, it will cause electro-optic ophthalmia, which is manifested as redness, tearing, and tingling of the eyes.

How to use UV lamps correctly?

1. Make sure there is no one in the room and the lights are off.

2. When there are dirty things on the surface of the ultraviolet lamp, clean it with alcohol, and use it after the alcohol has evaporated completely.

3. If the room humidity is greater than 60%, it is necessary to increase the light time appropriately.

4. Ozone may also be generated when irradiated by ultraviolet rays, and windows need to be opened for ventilation after disinfection.

Through the UV-C disinfection wand,it provides a 10-minute regular sterilization and disinfection function. The use of ultraviolet rays with high sterilization and disinfection efficiency and strong capabilities can interfere with viral RNA replication and at the same time inactivate its proteins, which can kill bacteria and microorganisms.

What is the Difference Between 2.4G and 5G WIFI?

When logging into your WiFi network,you'll notice two options available. You'll find a 2.4ghz option and a 5ghz option. These are two different frequency bands on your home network. You may have questions about how to choose between 2.4g and 5g?


The development of 2.4GHz and 5GHz WIFI:

The first generation of 802.11 only runs at 2.4GHz, and the ideal rate is 2M/s;

The second generation 802.11b only runs at 2.4GHz, and the ideal rate is 11M/s;

The third generation 802.11g/a, which runs at 2.4GHz and 5GHz respectively, with an ideal rate of 54M/s;

The fourth generation of 802.11n can run at 2.4GHz or 5GHz, and the ideal speed is 72M/s and 150M/s in the bandwidth of 20 and 40MHz;

The fifth generation 802.11ac(commonly known as 5G WIFI) only runs at 5GHz, and the ideal rate is 1GB/s;

IEEE 802.11 is a universal standard for wireless local area networks. It is a wireless network communication standard defined by the IEEE.

What is 2.4ghz and 5ghz band?

Wi-Fi 6 can support both the 2.4GHz and 5GHz, while Wi-Fi 5 only supports the 5G band, and Wi-Fi 4 only supports the 2.4G band. Common routers use both Wi-Fi 5 and Wi-Fi 4 protocol, so you can choose WIFI between 2.4GHz and 5GHz.

The 2.4G and 5G in Wi-Fi are radio frequency bands. 2.4G is an abbreviation for the 2.4GHz band, while 5G is the 5GHz band. A characteristic of wireless propagation is that the lower the frequency, the smaller the signal loss in the propagation, and the larger the range it can cover. The higher the frequency, the greater the signal loss during propagation, and the smaller the range that can be covered. In daily use, the main difference between 2.4G WIFI and 5G WIFI is in the transmission speed and stable connection.

The advantage of the 2.4G band is mainly that the indoor environment has better anti-attenuation capability than the 5G band, so it has a good ability to penetrate walls. Therefore, many people have larger indoor areas in their homes. If there are more rooms,sometimes the signal strength of the 2.4GHz on mobile devices is significantly better than the signal strength of the 5G band.

The advantage of the 5GHz wifi is that it has strong anti-interference ability, can provide larger bandwidth, higher transmission rate, and smaller delay. If the signal strength is good, the signal in the 5G band is preferred. The disadvantage of the 5G is that when encountering obstacles during transmission, the huge transmission loss, and the distance and range covered are not as wide as the 2.4G band.


Summary: The 2.4GHz band provides you with a longer range, while the 5GHz band provides more channels, and these channels are less subject to interference. When the signal strength of both frequency bands is good, the transmission rate of the 2.4GHz is not as high as that of the 5GHz. However, when there are many obstacles in space, the network quality in the 2.4G band may be better than the 5G band.

How to Use the 5GHz Band?

The first is whether the device supports 5GHz bands, including wireless routers and mobile device.

802.11a 5GHz; 802.11b 2.4GHz; 802.11g2.4GHz; 802.11n 2.4 / 5GHz; 802.11ac 5GHz supports the 5G band. It can be seen from the above that the wireless protocol supporting the 5G band can be checked in the parameters of the router or mobile device to see if it is supported the 5GHz Band.

How to enable 5GHz wireless network?

Log in to the router, and in the wireless settings, click the switch;

BASIC> Wireless: Enable SSID broadcast for each frequency band and configure different SSID for the two radios;

To avoid confusion 5GHz with 2.4GHz wireless, you can set a different wireless name or disable 2.4G.


The above is a detailed introduction of compare 2.4g and 5g internet to help you choose the best WIFI. You can place multiple router throughout your home, which is the easiest way to improve your network. Maybe you need a better router at wholesale prices, GEMWON can provide you. GEMWON is committed to providing electronics to add color to your life.

Intelligent security cameras for home suitable for home use, in addition to monitoring functions with most cameras, it also adds remote care, infrared night vision and two-way voice call functions. How do we choose a suitable smart ip camera simple home monitoring?


As an important part of intelligent security system, smart monitor is an indispensable device in smart home.

Ordinary cameras can record images and videos on the local or hard disk recorder. The smart monitor adds intelligent functions on the basis of ordinary cameras and has more powerful software. It can realize device linkage, motion tracker, human detection, voice intercom, cloud storage and more under the control of mobile phone apps or other methods Functions.

What to look for when buying home security cameras?

There are many types of smart security cameras on the market, and their quality and functions are different. So what aspects should be considered when choosing a smart monitor?


The angle of view is the field of view of the camera, which is mainly determined by the focal length of the lens. There are different focal lengths such as 2.8 mm, 4 mm, and 6 mm. The larger the focal length, the smaller the viewing angle.

Because the concept of focal length is not intuitive for users, smart security camera generally also indicates the viewing angle range and the distance suitable for monitoring.

The larger the viewing angle, the more objects you see at the same distance, and the larger the picture range, but the general picture distortion is more serious, and it is difficult to recognize small objects. The smaller the angle of view, the fewer objects you see, the smaller the picture range,and the stronger the ability to distinguish small objects in the image. So, for the perspective, you should choose according to the scope of you want to monitor.



Resolution refers to the pixel density of the camera, which largely determines the sharpness of the camera.Common smart security camera resolutions are: 480p, 720p, 960p and 1080p. The mainstream products on the market are 720p wireless wifi ip camera and 1080p,both of which have good definition. Of course, 1080p ip camera is better, and the resolution is generally around 1920*1080, which is what we usually call "full HD", and the price will be more expensive.

Different resolutions have different requirements for network and storage space. The higher the resolution, the more storage space the videos recorded in the same time will occupy, and the higher the network transmission requirements for video transmission. The data amount of 720p wireless wifi ip camera is about three times that of 480p.

Security Camera Surveillance Gimbal

The function of the PTZ is to allow the camera to rotate up, down, left and right, so that you can use the camera to view more area. Some PTZ cameras can realize 360-degree rotation,that is, the camera can be rotated to achieve video monitor. The security camera gimbal is more flexible, but it can only monitor one location at a time,so it is not suitable for the area that needs to be monitored around the clock.


Storage Method

There are three store ways of smart security camera, there is local storage, local NAS, and cloud storage.

The storage of local storage is the simplest. It only needs to insert a memory card into the camera housing. It does not need to occupy the network bandwidth. The disadvantage is that when the camera is lost, the records will be lost and video transmission is inconvenient.

The local NAS or hard disk video recorder (NVR) is to record the video data of the camera in the same intermediate NAS or hard disk recorder. To occupy the bandwidth of the disk, if loss of the camera will not cause the loss of video, but the NAS or hard disk needs to be added.

Cloud storage uploads the video data of the security camera to the cloud server in real time. It needs to occupy the network bandwidth of the home. At the same time, because of the storage space of the manufacturer's server is limited, cloud storage generally needs to be selected. Its advantage lies in the security of the stored data, even if the camera in the home is lost or the hard disk recorder is damaged, it will not affect the important video data.

Each of the three storage methods has advantages and disadvantages, and most of the intelligent surveillance cameras also support two or more storage methods. Users can choose one or more storage methods according to needs.


Motion Detection

Motion detection means that the camera can automatically identify the moving objects in the captured image to achieve security alarms and reduce the amount of stored data. At present,mainstream smart security cameras have a motion detection function, and the sensitivity of the motion detection function can be set. In terms of applications such as home monitoring, shop monitoring, and baby care. With some application, it can capture the movement of objects and send alerts to the phone. Achieve monitoring of home security.


Night Vision

The night vision capability of the home security camera is generally achieved by the infrared light supplement. At night or when the brightness is dark, the camera cannot receive enough light, so it can turn on the infrared light, because humans cannot see the infrared light, so there is no light pollution.


The maximum infrared distance is an important parameter index in the case of night vision, which mainly represents how far an object can be seen by the camera at night.

Voice Calls

Smart security cameras generally have a voice call function. You can seethe camera display and sound remotely through the mobile phone APP. At the same time, you can talk to the mobile phone microphone to transmit the voice to your home monitor.


The wireless security camera is small and convenient, no wiring required, and it can work in the network coverage area without being limited by space and layout.

Users only need to set the firmware and related applications, they can check the real-time situation in the home at any time through the mobile phone application, and they can also check the previously recorded videos through playback.

In addition, the wireless ip security cameras can also be connected to smart home systems such as smart doorbell, window magnets, and infrared detectors at home, and the linkage equipment can protect the home's safety in all aspects.
