What is masklab™️?

masklab™️ was founded in March 2020 by converting an old warehouse in Hong Kong into an ISO-certified cleanroom with two state-of-the-art NCM machine from Taiwan. We are currently able to produce up to 100,000 surgical masks a day.

Who is behind masklab™️?

masklab™️ was founded by 3i Corporation, a Hong Kong company in the manufacturing business since 1998 with US branch company 3i Products. Our most recent products were in the outdoor furniture and cushions category, which gave us experience with non-woven fabrics, the same materials used in mask-making.

Why are you called masklab™️?

Prior to making masks, we were a metrics-driven manufacturer who obsessed over engineering the highest quality products. Mask-making is a new endeavor for us, but we have brought the same type of fastidiousness to the craft. We believe mask producers should have the attention-to-detail on par with scientific laboratories, hence the name masklab. To stay true to the name, we have outfitted the factory with Hong Kong's first automated filter tester so that we can verify the quality of every batch of our filters.

What is the relationship with Mask Lab HK (

None. Mask Lab HK is another mask maker in Hong Kong, known for their midnight blue / orange masks. Their brand name is spelled with a space between 'mask' and 'lab' whereas our brand name is all one word - 'masklab'. We are both companies with vision of bringing manufacturing back to Hong Kong via the route of mask making so our interests are aligned - we bear no ill will towards them. There has been allegations of copying on both sides so to clear the air: According to whois, was registered on the 27th of March while was registered on the 7th of April. Our brands launched virtually at the same time so it's simply an unfortunate coincidence.

Who tests masklab™ products and how can I trust them?

masklab™ products are tested by Eurofins and Cambridge Materials.

Eurofins is one of Europe's leading testing laboratories. Its size is comparable to that of SGS. It is 1 of 12 labs named on EA's accredited labs list for EN 14683. You may learn more about them on their website or on Wikipedia.

Cambridge Materials is a Canadian laboratory accredited by the Standards Council of Canada since 1989. It's located near the University of Toronto and share its resources. You may find their listing on the SCC website here. You may also learn more about them on their website.

During the pandemic, many popular testing companies became completely over-capacity and had begun sub-contracting the tests to smaller labs, resulting in turnaround times of 50-60+ days. To mitigate our risk of delay, in May 2020 we decided to reach out to these sub-contract labs directly and submit our samples to a few of them. Not only does this yield more direct and faster results, with geographically-distributed testing, the reports are double confirmed and are much more reliable.
