Respiratory Mask


Breathability Virus removal Bacteria removal

Manufacturer's Description

The nanofibers are as thin as 0.003% of a single hair allowing for a high specific surface area with high porosity. The unique fibers provide a large catching capacity without compromising breathability. Humans in a sedentary state such as sitting or sleeping consume 6-8 litres of air per minute. Walking we consume 14-26 L/min while jogging more than 40 L/min. Surgical masks commonly seen are only tested against airflow of less than 30L/min so their effectiveness is questionable. The NASK Smart Mask is rigorously tested at 85 L/min to ensure high protection is provided whether at rest or active.

The unique formulation can effectively capture viruses and kill bacteria.

As tested by Nelson Labs (USA), SGS  and the Chinese Academy of Sciences – the NASK Smart Mask can kill 99% of bacteria within 5 minutes, and is the only Bacteria-killing Nanofiber mask currently mass produced.
