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

As the pandemic goes on, we find it difficult to protect us and our loved ones even in such a simple protective measurement such as face mask. 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 BFE 99%, 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

attractive & ergonomic

The printed masks use interactive designs especially for kids and preschoolers to raise their awareness of using mask as daily habit of new-normal. The mask covers nose to chin area, ensures a fit use through elastic fabric. The printed mask is equipped with IIMASK filter inside. Available for three sizes: adult, kid, and toddler

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.
