Can Face Mask With Respirator/ Fliter Be Anti-virus?

One doctor said on the SNS platform that breathing valve masks cannot be used to prevent viral infections. The reason he gave was, “It is difficult to reach the N95 protection level at the breathing valve.” This sounds reasonable. In addition, many people see pictures of doctors wearing masks without breathing valves. It is natural to think that it is safer without breathing valves. It is a pity that this statement seems reasonable, but in fact it has no scientific basis.

First of all, no matter whether it is the US FDA, CDC or NIOSH, the definition of N95 masks has never excluded the “breath valve”. On NIOSH’s page of previously certified N95 masks, we can see a large number of masks with breathing valves. Here only take some 3M products as an example.

Secondly, N95 test items are divided into salty and oily media, and the filtration efficiency of particles as small as 0.3 microns can reach 95% or more to pass the test standard. Take the LIFAair with the best protection among the mask samples we tested before as an example. The protection efficiency for 0.3um particles is more than 99%. Regardless of adult or child models, are equipped with breathing valve.

Third, the principle of breathing valve. Many people are led away because they think the breathing valve can also inhale air. On the contrary, the design of the breathing valve is very clever, similar to the air cylinder, but more delicate. When air is discharged from the mask compartment, the valve diaphragm is pushed out and opened at a certain angle to facilitate the rapid export of air and water vapor, so that it will not suffocate.

According to the previous recommendation of the US CDC, as long as it is a certified N95 mask, it is the best choice for preventing viral infections, which includes both with and without a breathing valve.

Others say that the main reason why it is not recommended to wear a breathing valve mask is to consider that if the person wearing the mask is already a virus carrier, it is not safe for the surrounding people.But in real life, no matter whether you wear a medical surgical mask with no airtightness, or a N95 mask without a breathing valve, the air we exhale cannot be without contacting the outside environment. Medical surgical masks that leak everywhere can also spread germs when they exhale.

The conclusion is that ordinary people wearing masks for breathing valves can be used with confidence, but it is not suitable for use in hospitals.

We believe that for ordinary people, as long as they are qualified N95 masks, even if they are not medical grade, they can also effectively protect against virus intrusion, and N95 face masks with breathing valves can also effectively protect against virus infections.

What’s The Difference Between KN95, N95 And FFP3 Face Mask?

Tags :

Category : Blog , Tips & Tricks

Many people are asking what is the difference between normal face masks, N95, KN95 , KF94, FFP2 respiratory face masks and face mask shields.

Compare N95 v KN95 v FFP2 face masks:

In summary, They are basically all the same. They stop 95% of particles >0.3 microns in size. KN95, KF95 and FFP3 face masks are N95 face mask alternatives & N95 equivalents. They are all the same.

Can wearing a normal medical face mask protect you from Coronavirus?

A regular loose-fitting face mask will not stop the coronavirus. They can help you stop spreading sneezes, coughs and fluids to other people. This is how the coronavirus spreads. People wearing face masks should disposed of them after every use.

Can a respiratory face mask stop the coronavirus?

Yes, respiratory face masks (they fit tightly around your nose and mouth), commonly know as N95 face masks can protect against the virus if you wear and use them correctly. You need to fit them correctly so they are tight to face.

These masks are thicker than a normal medical mask. However, they need to be fitted properly, and they are not designed to be used for a long period. 30 minutes is an average time to wear. Some users will have trouble breathing. You can’t wear N95, KN95 and FFP3 masks if you have a beard.

Can a Virus Face Mask Shield stop the Coronavirus?

Yes, they will stop fluids and splashes going in your eyes, nose and mouth from coughs, sneezes and other fluids.

Face Mask Shields are made out of plastic and will stop respiratory droplets (coughs, sneezes and other fluids) going in your mouth, eyes, and nose. This is how the coronavirus spreads.

N95, KN95,and FFP3 comparison

In summary, different countries use different codes and numbers to name their respiratory face masks. They are all very similar.

The N95 is the USA standard
The KN95 is the China standard
The KF94 is the Korean standard
FFP3 is the EU standard. This includes the UK.

Standards of 3 Ply Surgical Protective Masks and Respirators

Each of these two types of protective masks is subject to different standards and regulations depending on the country or geographical area.

protective masks

In Europe, they must comply with the European standard EN 14683, which has 3 levels of bacterial filtration efficiency (BFE1, BFE2, Type R). In the United States, they must respect ASTM standards which have three levels of protection (from low risk of exposure to fluids to high risk of exposure to fluids).

In Europe, they must meet the European standard EN 149: 2001 which has three classes of disposable particulate respirators (FFP1, FFP2 and FFP3).

RespiratorsFFP1 refers to the least filtering of the three masks with an aerosol filtration of at least 80% and leakage to the inside of maximum 22%. This mask is mainly used as a dust mask (home renovations and various types of work).
FFP2 masks have a minimum of 94% filtration percentage and maximum 8% leakage to the inside. They are mainly used in construction, agriculture, and by healthcare professionals against influenza viruses. They are currently used for protection against the coronavirus.
FFP3 protective masks are the most filtering mask of the FFPs. With a minimum filtration percentage of 99% and maximum 2% leakage to the inside, they protect against very fine particles such as asbestos.

In the United States, respirators must meet NIOSH (National Institute for Occupational Safety and Health) standards. Within this standard, there are several classes of respirators depending on the degree of oil resistance:

Class N: no oil resistance. A distinction is made between N95, N99, and N100. The number after the letter indicates the percentage of filtration of suspended particles.
Class R: mask resistant to oil for up to eight hours. Here again, a distinction is made between R95, R99, and R100.
Class P: a completely oil-resistant mask. There are also P95, P99, and P100.
