What are the best performing, most breathable and most comfortable masks out on the market in 2021? Masks from South Korea have become customized so you can find the right balance between performance and comfort. Here are the specs for the KF94, KF80 and KFAD along with references to dental masks, surgical masks and neoprene masks. The line of BMW cars are used as the main analogy along with Maserati, Ferrari and Lamborghini.

KF94 = 94 percent filtration (Highest Performance, Less Breathability). Filters air particles (dry) and air droplets (wet), water resistant from rain.

KF80 = 80 percent filtration (High Performance, Moderate Breathability). Filters air particles (dry) and air droplets (wet), water resistant from rain.

KFAD = 50 percent filtration approx. (Medium Performance, High Breathability). Filters air droplets (wet) and water resistant from rain.

Dental Masks = 50 percent filtration approx. (Average Performance, High Breathability). Filters air droplets (wet). Gets soaked easily in rain.

Neoprene Masks = Dubious filtration (Low Performance, Low Breathability). Reusable.

Surgical N95 Masks = Medical-level performance, Low breathability. Used when tightest fit necessary to prevent any air to flow in from edges of mask.
