Di Nano mask comes with 5-layers with middle nano layer using nonporous membrane as physical filter. Unlike other 3-layer regular mask using Meltblown electret filter, where its filtration efficiency decreases exponentially with time as a result of the electrostatic decay, and deteriorate further by air moisture or exposed to solvents including water, ethanol and other disinfectant, the filtration rate of the “Ucheenano” filter would not decade after repeated cleaning and still able to maintain highest protection against any airborne contaminants.

One key merit of using DI Nano Mask is that it not only has highest filtration efficiency, but it’s also very light and easy to use that you could wear for a whole day. And if you would like to reuse it (Washable 5 time) , simply disinfect by spraying alcohol or hand wash and soak with soap water, air dry.
