What is the difference between KN95 and KN94 masks?
KN95 Mask
Who should wear one: These masks should be worn by anyone in low- to moderate-risk situations, such as going to the grocery store or attending an outdoor function.
KN95 masks are regarded as the Chinese counterpart to N95 masks. They have a tent-like form that generates a little air pocket between your nose and the fabric, which appeals to a wide variety of people: They felt more breathable, less obstructive and suffocating.
However, because KN95 masks are not regulated by the US’s mask regulatory organization, NIOSH, they are not as effective as N95 masks. Manufacturers of KN95s may apply to the FDA for emergency use authorization for usage in health care settings. Indeed, the FDA has previously given EUA to numerous KN95 masks.
In September 2020, the Emergency Care Research Institute issued a paper raising concerns over fake KN95 masks. According to the survey, up to 70% of KN95 masks imported from China do not perform as well as N95 masks in terms of filtering performance. ECRI issued a notice after learning that numerous hospitals were acquiring these masks, which could pose contamination issues in medical facilities treating patients with COVID-19.
Outside of health care and high-risk environments, this is not a significant issue. Wearing KN95 masks can benefit the general public. Even if KN95 masks do not fulfill NIOSH criteria for filtering effectiveness, they are likely to be more protective than ordinary surgical masks and cloth face masks made of cotton, nylon, or another nonmedical fabric.
KF94 Mask
Who should wear one: These masks should be worn by anyone in low- to moderate-risk situations, such as going to the grocery store or attending an outdoor function.
KF94 masks are gaining popularity at the moment. The “KF” stands for “Korean filter,” while the 94 indicates the filtering efficiency of the masks. These masks filter 94 percent of pollutants down to 0.3 microns in size, according to South Korean government guidelines. They are designed with ear loops, an adjustable nose bridge, and side flaps for a secure fit.
Researchers discovered that KF94 masks are just as good at filtering SARS-CoV-2 as N95 masks in a very limited August 2020 investigation (just seven subjects). Unlike KN95 masks, which have been certified by the Chinese government, KF94 masks have not yet been awarded an EUA by the FDA for use in health care settings.
Nonetheless, like KN95s, KF94s are a significant upgrade over the single-ply cotton face cover you’re presumably wearing.
- Excellent melt-blown cloth for filtering with an electrostatic charge.
- BFE & PFE>99% (Particulate Filtration Efficiency)

- A nonwoven outer layer that is water resistant serves as a filter for dust and microorganisms.
- Soft and fine inner non-woven fabric that is skin-friendly and appropriate for sensitive skin
- Sanitary and convenient to use
- Bacterial and dust prevention
- Superior quality, cleanliness, safety, and comfort
- MDA (Medical Devices Authority)
Instructions for use:
- With the colourful side facing outwards, cover your lips, nose, and chin.
- Ensure that the nose clip is positioned correctly.
- Adjust the nose clip to conform to the shape of your nose.
- Pull the mask’s lower end up to cover the chin.
- Adjust the mask to ensure a proper fit and protection.
This KF94 face respirator are designed to prevent unfiltered air from entering your face and to fit securely. Its three-dimensional design is form-fitting and protective while allowing for breathability and communication. The side flaps remain flat against the user’s face, minimizing the likelihood of the wearer readjusting their face mask. This creates a solid seal and double protection for the face mask on all sides. The face mask is constructed of a double-layered melt-blown filter fabric that provides 98 percent BFE (Bacterial Filtration Efficiency) and 98 percent PFE (Particle Filtration Efficiency), effectively filtering out bacteria, pollutants, pollen, and dust particles from the surrounding environment.
- Ideal for daily protection at work or play.
The KF94 Face Respirator has the following features:
- 4 layers of protection (2 inner layers of melt-blown filter cloth) 98 percent BFE and 98 percent PFE (Particle Filtration Efficiency)
- Three-dimensional design for improved breathability and communication
- A snug, self-sealing fit
The following instructions describe how to operate a Neutrovis KF94 Face Respirator:
- Top and bottom flaps should be unfolded.
- Secure the ear loops and place the mask over your face.
- Adjust the metal strip to fit your nose’s shape.
- Remove the worn mask by grasping the ear loops only.
