Selecting The Right Medical Masks Between Kn90 And Kn95

Selecting The Right Medical Masks Between Kn90 And Kn95

Face masks are playing are a vital role in preventing the spread of coronavirus. Although they are plenty of them in the market, not all of them satisfy the standards required. While some people are eager to out different types of masks, others are looking forward to the recommended ones. We decided to highlight some of the significant differences and similarities with the Kn90 and the Kn95 becoming popular day by day. The following is a comparison between kn95 vs kn90.

  1. Filtering Success Rate

    As their names suggest, the Kn95 can filter up to 95 percent of the pollutant and traps from the air while Kn90 has a successful filtering rate of 90%. Their filtering success rate is quite remarkable since we cannot achieve 100% success. Both masks provide quite significant protection against infections.

  2. Quality

    A 4-ply face filter with an inner carbon of 2.5pm layer is used on both masks to increases their effectiveness in preventing impurities from reaching your face. Contaminated air may contain microscopic contaminants as well as other large particles of fur, pollen, molds, and dust. These masks are capable of filtering pollutants as tiny as 0.3 microns. They are also able to protect you from unpleasant smells.

  3. Structure

    Kn90 and Kn95 come in two strap structures: one that can go round your head, and the other hangs around your ears. In both cases, the straps are adjustable to fit your preference.

The Kn90 mask has breathing valves over your nose to make breathing easy. Even though the Kn95 lacks the breathing valves, their fabric is modified to draw air into your nostrils. For maximum protection against splashes, both masks posses three pleats. One runs below the chin, the other over the mouth, and the last one shields your nose. They are all designed to suit the shape of the part they should cover.

  1. Durability

    Both Kn90 and Kn95 comprises of an excellent fabric material that feels comfortable on your face. Both masks are strong and durable, which means that you can wash them without disfiguring them. The fabric stretches to form a tight barrier over your face without losing its contours. The Kn95 can last up to 40 hours, while Kn90 can serve 100 hours.

  2. Disinfection and Sterilization

    If you have to reuse a mask, it is advisable to disinfect and sterilize it. The Kn90 will require you to wash it with soap and water then let it dry naturally under the sun. The sun acts as a further sterilizer; therefore, it is essential to make it stay a bit longer in the sun. For the Kn95, experts recommend using hydrogen peroxide spray, heat around 750c, and for not less than 30 minutes. Ultra Violet Germicidal Irradiation(UVGI) can also be of help. Ensure you do not disinfect a spoiled mask; instead, dispose of it in the recommended ways.

  3. Comfort

    The fabric material used has an elegantly soft feel on your face. The masks’ inner layers are made of anti-allergy layers to protect people with sensitive skin. Besides, the Kn90 has a clip to ensure you do not pull it while inhaling. The edges are tight and elastic enough not only to provide you with maximum protection but also to ensure you do not suffocate. Both masks have modifiable straps for you to determine how tight or loose you want your cover to fit.

In conclusion, both Kn90 and Kn95 will offer you maximum protection against most of the impurities. These face masks have a filtering success rate of 90% and 95%, respectively, making them highly effective. Their fabric anti-allergy material makes both covers not only comfortable but also friendly to the skin. They will allow you to breathe freely. Kn 90 and Kn95 can be disinfected and reused if contaminated. Experts advise not to reuse spoiled mask; instead, you should dispose of it in the right manner.

kn95 vs cloth mask: What’s the difference?

kn95 vs cloth mask: What’s the difference?

Pollution, in the modern-day world, has become inevitable. The atmosphere has a lot of impurities present, which are not part of the fresh air human beings consume. Facemasks have been known to play a significant role in filtering the air we breathe in, especially during this COVID-19 pandemic. For this case, let’s compare the Kn95 masks with Cloth masks.

Kn95 VS Cloth masks

A Kn95 mask is a high-quality mask that meets industrial standards. This means that a Kn95 mask has the capability of providing a ninety-five percent filtration rate against dust particles, respiratory droplets, and germs. To make sure that this is effective, it has five layers of protection. On the other hand, a cloth mask’s performance might be less effective since most of them are made from fabrics that are improvised, hence poor filtration.

Despite their ineffectiveness, cloth masks might prevent transmission through contact. They prevent you from touching your cheeks, nose, and mouth. Having it on your face, especially at this time, while fighting the spread of COVID-19, they might as well act as a reminder for not touching your face.

Which materials are these masks made of?

Cloth masks can be made from two materials; fabrics that are tightly woven and fabrics that provide static electricity such as silk. Researchers claim that these two materials may act well in preventing the entry of particles. The Kn95 mask is made of 5 layers. The first layer is made up of woven polypropylene, which serves as a micron dust filter. The second layer is made up of a highly dense filter cloth that also filters micron dust. The third layer consists of an activated carbon filter that gets rid of any unpleasant smell. The fourth layer, just as the second layer, is made up of highly dense filter cloth, and lastly, the fifth layer consists of a non-woven polypropylene that filters missing dust.

Do hospitals recommend these masks?

Kn95 masks are certified masks that are scientifically proven to provide a 95% filtration from germs and respiratory droplets. Hospitals highly recommend kn95 masks since they create a barrier for bacteria, whereas CDC(Centres for Disease Control and Prevention) says that there is no abundant evidence to prove whether the use of cloth masks is effective. Although, if you do not have any other option, especially during this time of the COVID-19 outbreak, the idea of cloth mask is better than nothing. Ideally, combine the use of cloth mask with a face shield that will cover your face thoroughly.

How long do these masks last?

Research has been carried on the Kn95 to see how long they would last. After the study, it was evident that the mask still maintained a 95% filtration rate in 2 days of use, but on the third day, its efficiency declined to 94% filtration rate. This research showed that the mask could not go for more than two days without replacement. Unlike the Kn95, a cloth mask is reusable. It can go for as long as one wishes provided that it is washed after use.

In conclusion, the Kn95 mask is highly recommended since it has a high filtration rate compared to a cloth mask.

An In-depth Understanding of kn95 vs kf95

The coronavirus pandemic has hit the world by storm, and suddenly everyone is required to wear a mask whenever they go out to the public. There are a lot of uncertainties brought about by this disease, which has been quite a frustration for people worldwide. However, everyone is hoping for this to pass so that things can go back to normal again.

The kn95 and kf95 are some of the most sought-out masks currently, and learning more about them is essential to helping you make the right choice, whenever you are out shopping for a face mask. So, here are some comparisons between these two types of masks.

Filter Performance

When it comes to filtering performance, the kn95 masks are a bit better compared to the kf95 masks. The kn95 masks have 95 percent filter performance efficiency while the kf95 masks have 94 percent filter performance efficiency. Therefore, the efficiency of kn95 is much better than kf95.

  1. Test Agent

    The test agent for the kn95 is sodium chloride (NaCl), while the test agent for the kf95 is sodium chloride (NaCl) and paraffin oil. As you can see, the kf95 has a combination of two agents, while the kn95 only has one test agent.

  2. Leakage Potential

    When it comes to the leakage, you need to know that almost every mask out there has a leakage potential. Both the kn95 and kf95 have an 8 percent total inward leakage, which was tested on human subjects, with each performing exercises. The percentage is an arithmetic mean for each of the masks and was thoroughly researched and tested to ensure the results are as accurate as possible.

  3. Inhalation, Flow Rate, and Exhalation

    When it comes to inhalation, the kn95 masks have an inhalation resistance – maximum pressure drops of approximately 350 pa, while the kf95 masks have 70 pa at 30 L/min, 240 pa at 95 L/min, and 500 pa when clogging.

When we talk of the flow rate, the kn95 masks have an 85 L/min flow rate, while the kf95 masks’ flow rate tends to vary.

The exhalation valve leakage rate for the kn95 is depressurization to 0 Pa, which is approximately greater or equal to 20 seconds. However, that of the kf95 has been rendered not applicable since not much information has been provided about the masks. If you need Kn95 mask today, you can find the kn95 mask for sale here.

CO2 Clearance

When it comes to the CO2 clearance, have an approximately 1 percent of the CO2 clearance, similar to the kf95 masks which also have 1 percent CO2 clearance. This is also another thing that these two types of masks have in common

A Detailed Look Into Kn95 vs surgical Face Masks

A Detailed Look Into Kn95 vs surgical Face Masks

Both surgical and Kn95 face masks are perfect examples of personal protective gear. Both are utilized for safeguarding the wearer from the liquid that can contaminate the face and airborne particles. It is essential to note that the best way to outmaneuver airborne transmission is using a combination of related interventions.

Surgical masks
• A surgical mask can be defined as a loose-fitting and not reusable device that builds a physical barricade between the nose and mouth of the wearer and contaminants in the immediate surrounding. In addition, they are labeled as either surgical, dental, medical procedure or isolation masks. Surgical masks should not be shared.
• Surgical masks contain three layers, including a mixture of non woven material. The middle layer contains melted brown fabric which performs as a filter.
• They have different ability to protect the wearer from coming into contact with liquids and they come in different thickness.
• They are meant to assist in blocking splashes, splatter, large-particle droplets, and sprays that contain bacteria and viruses (germs) if worn appropriately. They also help in minimizing the exposure of wearer’s respiratory secretions and saliva to others.
• The surgical mask does not block or filter small particles that can be transmitted through sneezes, coughs, and other medical procedures. Additionally, because of the loose fit linking the wearer’s face and the surface of the mask, it does not give full protection from microbes.
• Leakage can occur around the edge of a surgical mask when the user inhales.
• They are intended to cover the nose and mouth loosely, are not sized for personal fit, and are designed to be worn just once

Kn95 masks
• Kn95 mask or respirator can be described as a piece of respiratory protecting equipment that is designed to attain a close facial fit and competent filtration of airborne elements.

• They are designed to prevent and minimize the wearer’s exposure to airborne contaminants.
• Dissimilar from surgical masks which one size is meant to fit all, Kn95 masks are available in different sizes and can be chosen based on how best it fits the users face to create a tight seal.
• It is expensive compared to surgical masks, and it is not recommended for kids or small-sized teenagers.
• Unlike surgical masks, it is intended to filter smaller contaminants. Many Kn95 masks contain a filter at the front which forces air to be filtered, making them more effective.
• When properly donned and fitted, only minimal leakage occurs around the edge of a Kn95 mask when the user inhales.
• Have particular use instructions, limitations, and warnings, especially in healthcare facilities.

Both Kn95 and surgical masks should be disposed after each person encounter. In addition, they should be disposed when they become deformed, damaged, or contaminated with respiratory secretions, blood, among other bodily fluids. Also, if they don’t make an effective seal to your face any longer, becomes visibly dirty or wet, and when breathing through them becomes problematic. Like any other elements that pollutes and contaminates the environment, both kn95 and surgical masks should be discarded safely. It is also essential to clean the hands after handling the worn mask.

Face masks have become the norm due to the current pandemic that we are facing in the world. Almost everywhere you go, as long as you’re in public, you are required to wear a face mask to ensure that you are safe.

The coronavirus pandemic has, without a doubt, brought so many changes and forced people to stay at home waiting for things to get better. A lot of face masks have come up in the picture throughout this situation, and choosing the most suitable ones has become quite a daunting task.

Here, we’ll compare two types of face masks to help you understand them better.

Kn95 versus N95 Face Masks

The kn95 face masks are quite popular with people, which make them very much available in the market due to the demand from the people. Here are some of the features of the kn95 face masks.

Filter Performance Efficiency

The filter performance of the kn95 mask is approximately greater or equal to 95 percent, similar to the n95 face masks. Therefore, that shows that these masks are quite ideal since they can filter small particles better than other kinds of face masks.

Test Agent and Flow Rate
Both the test agent for the kn95 and n95 face masks is sodium chloride (NaCl). This makes these masks quite effective since they have been tested with sodium chloride to ensure they are in perfect condition and able to help you breathe better and filter out anything.

The flow rate of the kn95 and the n95 face masks is 85 L/min, which is quite less compared to other face masks like P2 and FFP2.

Inhalation and Exhalation

The kn95 face masks have approximately 350 Pa inhalation resistance and maximum pressure drop and 250 pa exhalation resistance maximum pressure drop. The n95, on the other hand, have an inhalation resistance of approximately 343 Pa and exhalation of 245 Pa.

Force Applied

The kn95 face masks have -1180 Pa force applied, which is quite high compared to the n95 face masks, which have a -245 Pa force applied and other face masks like the P2 that has -250 Pa force applied.

The CO2 Clearance

The CO2 clearance of the kn95 face mask is greater or equal to 1 percent, similar to the n95 face mask and other face masks like the FFP2 and P2.

Inward Leakage

The inward leakage information for the n95 face masks is unknown as there isn’t any information provided, while that of the kn95 face masks is an arithmetic mean of 8 percent. The inward leakage was tested on humans while they were performing exercises, and it brought the mentioned results.
