When your life is at stake, trust only KF94, the golden standard of Korea!
KF94 masks protects you against BOTH Covid-19 and haze (PM 2.5) compared to surgical masks. One mask DOUBLE PROTECTION!
What are KF94 masks?
KF94 is the most popular highest Korean mask standard used throughout Korea.
There is a KF99 which has the highest filtration level but it is much harder to breathe through so its not popular. For practical reasons, 94% filtration level of viruses, fine dust (PM2.5) and bacteria is sufficient. KF 94 is the best and most loved standard in Korea.

How does KF94 compares with USA N95 and the European FFP2 standard?
You can see from the chart below that the performance is about the same. However, there is ONE BIG DIFFERENCE.
N95 and FFP2 standards are for medical use. They are not recommended for consumer use. Whereas KF94 on a daily basis throughout the year is being used in Korea by consumers due to the year-round fine dust problem that is being blown from China to South Korea.

Because the KF94 standard is designed for consumer use, they are many design differences between KF94 and N95 and FFP2.
The KF94 is consumer friendly. There are at least 4 differences:
1). KF94 is very user friendly. As it is designed for the consumers, it can be used by anyone, including kids.
2). They are easy to put on and take off allowing the user to easily remove in restaurants etc.
3). They are much easier to breath through.
4). They can be folded and easily carried around.

This explains why the KF94 masks are the most popular highest standard masks used throughout the year in Korea. it is also trusted  worldwide by consumers who are familiar with Korean and Korean products.

Note: There is a lower standard called KF80. Then below that is the KFAD which essentially is what most countries call the surgical masks. Surgical masks are the lowest standard and offer the least level of protection. It is absoultely useless against haze and PM2.5. Against Covid, surgical masks offer limited protection in non crowded, non intimate settings. When you're in crowded settings like the lifts, cinemas, plane etc, always use KF94 masks instead of surgical masks.
Some countries like the CDC have recommended using 2 layers of surgical or cloth masks. When you use KF94, there is no need to do that. Just one layer of KF94 is all you need because it will fit snugly around you face due to the ergonomic design that Korean masks manufacturers have mastered from decades of mask making!
Smelling burnt smell or getting headaches? Haze is back! Protects yourself against PM2.5!
