Understanding the Differences: N95, KN95, and KF94

The N95, KF94, and KN95 masks are all effective at filtering particles, but they mainly differ in the regulatory standards and design according to their country of origin:

  •  N95: They meet American standards set by NIOSH (National Institute for Occupational Safety and Health). These masks must filter at least 95% of airborne particles. They fit tightly to the face and provide a proper facial seal, making them efficient in protecting against airborne particles and droplets.

  •  KN95: They follow Chinese standards, equivalent to N95 in terms of filtration efficacy, but can differ in terms of fit standards and leak-proof testing. They are also designed to filter 95% of particles, but certification norms and testing can vary.

  •  KF94: They are certified in South Korea, with "KF" standing for "Korean Filter." The number 94 indicates that they are designed to filter out 94% of particles. They often feature a "boat-shaped" design and are considered equivalent to the FFP2 masks in Europe. They offer a comfortable fit and good filtration but with slight differences in efficiency compared to N95 and KN95.

Important: All these masks are effective in protecting against hazardous particles and pathogens when used correctly. You can find them at the following link.

Factors to Consider When Choosing Your Mask

  • Certification and Authenticity: Ensure that the mask is certified by the corresponding regulatory bodies and is genuine. There are many counterfeits on the market, so it is crucial to buy from trusted suppliers.
  • Purpose and Environment of Use: Your environment and purpose of use are also crucial. For instance, in medical environments, N95 masks are preferred, while for daily use, a KN95 masks or KF94 might suffice.
  • Type of Filtration and Efficacy: Ensure that the mask offers an adequate level of filtration for your needs. (N95, KF94, and KN95 masks are the most effective).

Tip: To verify the authenticity of a mask, you should evaluate the package (that it is intact and uncorrupted), look for quality seals and certifications on the packaging, and above all, purchase from reliable suppliers like Cetrix Store.

Maintenance and Care of Your Mask

N95, KF94, and KN95 masks are primarily designed to be used as disposable masks, but if you are going to reuse them, consider the following:

  1. Inspect before each use: Before reusing or if you have taken it off for a moment and are going to put it back on, check for damages or signs of wear, such as deterioration of the filtration material or the elastic bands. Do not reuse it if it is visibly dirty, wet, or damaged.
  2. Limited use: If the mask is used in a high-risk environment, such as in close contact with sick people, it is better not to reuse it.
  3. Avoid disinfection with heat, moisture, or chemicals, as trying to clean the mask or wash it compromises the integrity of the mask.
  4. Do not share the mask: You should never share your mask with another person, even after attempting to clean it and disinfect it.
