“IITOYA launched IIMASK, a membrane-based mask filter to help the community battling off COVID-19”

As the pandemic goes on, mask scarcity becomes one major problem. IITOYA helps to provide maximum protection through mask-filter called IIMASK, which can be inserted to any cloth mask with pocket. The filter is tested BFE 99% (Bacteria Filtration Efficiency), hence proven effective to filter virus, bacteria and micro particles; breathable, and comfortable to use. We humbly present our technology for your daily protection

As the virus spreads through droplets and aerosols, it is important that the mask filter can repel water. IIMASK filter is hydrophobic with size large enough to cover both nasal and oral openings, hence provide maximum protection on any cloth mask.

BFE - 99%

Bacterial Filtration Efficiency (BFE) is one of five performance metrics of mask.
This test measures the percentage of bacteria larger than 3 microns filtered out by the mask. The challenge material used is Staphylococcus aureus. IIMASK BFE result shows the efficiency of 99%, or having excellent resistance to bacteria penetration

blow test

While most cloth mask users utilizes 5-6 plies of tissue as their filter, IIMASK offer a breathable-thin filter with BFE 99% as tissue replacement. It is proven effective during blow test of a lighted candle. Forget the bulky tissues.

Aside of production of mask filter, we also provide printed mask for preschoolers, kids, and adults. Custom printed masks for companies, hospitals, schools or offices are also possible by request. Kindly contact our customer service to do so
