Five-Layer Filtration: The black KN95 mask features five layers of specialized materials that work together to provide efficient filtration of airborne particles. These layers typically include a non-woven outer layer, a melt-blown filtration layer, an activated carbon layer, a melt-blown filtration layer (second layer), and a soft non-woven inner layer. This multi-layer design enhances the mask's ability to filter out particles with a size of 0.3 microns or larger.

High Filtration Efficiency: The KN95 mask is designed to have a minimum filtration efficiency of 95%, meaning it can filter out at least 95% of airborne particles. This high level of filtration helps reduce the risk of inhaling harmful substances and provides a reliable barrier against contaminants.

Black Color: The black KN95 mask features a stylish black color, offering a visually appealing and modern option compared to traditional white or blue masks. The black color may be preferred by individuals who want a mask that is both protective and aesthetically pleasing.

Secure Fit: The mask is designed to fit securely over the nose and mouth, creating a seal to minimize air leakage around the edges. This helps ensure that the majority of the inhaled and exhaled air passes through the filtration layers of the mask, maximizing its effectiveness.

Adjustable Nose Clip: The KN95 mask often includes an adjustable nose clip or metal strip embedded in the upper part of the mask. This feature allows the wearer to mold the mask around the nose, providing a snug fit and reducing fogging of glasses or goggles.

Elastic Ear Loops: The mask is typically equipped with elastic ear loops that securely hold the mask in place over the ears. The ear loops are designed to be comfortable for extended periods of wear while maintaining a secure fit.

Breathable and Comfortable: Despite the multiple layers of filtration, the black KN95 mask is designed to be breathable, allowing for easy airflow during respiration. The materials used are generally soft, non-irritating, and comfortable against the skin.

Usage and Duration: The black 5-layer KN95 mask is suitable for various settings where respiratory protection is required, such as healthcare facilities, construction sites, industrial environments, public transportation, and crowded areas. The duration of use may vary depending on the specific circumstances and guidelines.
