Core Strengths in Biological Filtration and Treatment

An advanced development and manufacturing of bioelectret company for electroceuticals

C-POLAR™ is a biotech startup founded in Hong Kong in 2020. Our latest invention, C-POLAR™ spunlace successfully stabilizes and reinforces high surface charge density over the fabric surface making it the most effective air filtration material which captures and kills over 99.9% of viruses and bacteria including COVID-19 in under just 5 mins.  Our material is made of 100% safe materials, free of metallic ions and conforms to the highest safety standards set by all leading regulatory bodies.

C-POLAR™ is highly versatile and is being developed in a multitude of valuable applications in the US, Europe, Japan, Thailand and China, such as air filters in heating, ventilation (HVAC) and air conditioning system in buildings, automobile ventilation systems and more to come. Our team is working diligently with different governments to use C-Polar™ to create solutions in the fight against the global battle against COVID-19.

C-POLAR™ has the clear ability to:

  • Arrest 99.9% SARS-229E and Coxsackievirus B6

  • Inactivate 99.9% SARS-229E and Coxsackievirus B6 in 5 mins

  • Given that SARS-229E and Coxsackievirus B6 are structurally quite different, there is a high likelihood of seeing similar results with other viruses as well.

  • Eliminate 98% SARS-CoV-2 in 5 mins and 99.6% SARS-CoV-2 in 30 mins

  • No cytotoxicity to human lung cells and green monkey kidney cells

  • No reduction on cell sensitivity


Our Story

At the beginning of the COVID-19 outbreak, the market was lacking supply of face masks due to the scarcity of “meltblown” fabric, a critical component which allows face masks to filter particulates too tiny to be filtered by regular fabrics.

Our founders came together in hopes of developing a new technology that could arrest and kill viruses and bacteria in February 2020. Through their research of the physical properties of viruses, they hypothesized that a bioelectret carrying a strong positive polarity might arrest and kill a virus with negative polarity. After days of developing and coordinating virus testing with several overseas institutions, our founders achieved their scientific breakthrough in mid-2020.

Their discovery of the C-POLAR™ is capable of protect people from viruses and bacteria to a much greater degree than “meltblown” fabric. The C-POLAR™ bioelectret is capable of arresting and killing 99.9% of viruses and bacteria within a short contact time (within 5 minutes), including COVID-19 virus; and carries no toxicity, meaning it is not harmful to humans. With this exploration, our team then experimented with different fabric bases and discovered the combination of C-POLAR™ bioelectret and natural cellulose provides the best viral filtration. Further testing with recognizable virus test laboratories in EU and US also verified performance of C-POLAR™.

Our team believes that the usage of the C-POLAR™ is not only limited to air filters and face masks, but we also believe that our patented biotech will be able to extend to broader usages across different industries to benefit the public immediately and in the future.
