A Reusable and Comfort Facemask as a Barrier to Microorganisms

HKRITA has developed a groundbreaking washable facemask designed to deliver enhanced filtration efficiency, made with materials specially selected to maximise wearer comfort as well as sustainability performance.

HKRITA’s washable facemask is made by a one-of-a-kind technique that enables it to carry out different functions, such as antimicrobial action, particles filtration within the layers of a facemask. In other words, the facemask is very effective in keeping microorganisms and bioaerosols away from users.

This groundbreaking mechanism allows the facemask to maintain a highly effective barrier—even in situations with a high incidence of particle matters—without sacrificing air permeability. Its performance is unaffected by environmental factors like humidity.


The facemask features an ergonomic design, with a dimensional cut designed to seamlessly and comfortably fit the face, and create a sealed structure around the face to improve the barrier effect. The multilayer design maintains excellent air permeability and breathability and its moisture control function provides improved thermal comfort within.

Along with its ergonomic design, the facemask is made with materials developed for washability, extending its life cycle. The facemask retains its filtration efficiency and a high bacterial elimination performance even after 20 times of washes. The addition of aesthetically pleasing designs may also transform the facemask into a fashion accessory, further encouraging reuse.

While reusability is an important factor in the facemask’s sustainability performance and in the reduction of production cost, another cost-effective and eco-friendly aspect is that the facemask’s 3D design is carried out by a 2D cutting. This allows for simple packaging, thus reducing unnecessary waste.

Technological breakthrough

With its high level of comfort and adaptability to various environmental conditions, the washable facemask can be positioned as an economical, sustainable, and reliable choice for use either in a medical setting or for personal protection against pollution and airborne diseases.
