What is masklab™?

masklab™ was founded in March 2020 by converting an old warehouse in San Po Kong into an ISO-certified cleanroom with two state-of-the-art NCM machine from Taiwan. In the few months shortly after, we have expanded to 2 floors and 6 machines, making various types of masks. We are currently able to produce up to 100,000 surgical masks and 40,000 respirators a day.

Who is behind masklab™?

masklab™ was founded by 3i Corporation, a Hong Kong company in the manufacturing business since 1998. 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 (masklab.co)?

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, masklab.hk was registered on the 27th of March while masklab.co was registered on the 7th of April. Our brands launched virtually at the same time so it's simply an unfortunate coincidence.

How do I contact masklab™?

If you have any general enquiries or feedback, the best way would be to send an e-mail to hello@masklab.hk. We’re available to help from Monday to Friday, 9AM—6PM.  


What is the standard of masklab™ 3-ply surgical face mask?

masklab™ products have been tested by two labs to two different standards: Eurofins for EU's EN 14683 and Nelson Labs for US's ASTM F2100.

Our products have achieved both EN 14683's highest level of Type II R and ASTM F2100's highest level, Level 3. You may view the full test reports below by clicking on them:



Who tests masklab™ 3-ply surgical face masks and how can I trust them?

masklab™ products are tested by Eurofins and Nelson Labs.

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.

Nelson Labs is the leading global provider of laboratory testing, and is one of the world's first and only provider of the Particle Filtration Efficiency: Latex Particle Challenge Test. Their main laboratory is in Salt Lake City, Utah, United States. You may learn more about them on their website.

What is the standard of masklab™ Korean-style Respirators (KF Series)?

masklab™ products have been tested by SGS to the most stringent EU PPE mask standard EN 149. Achieved oil-free high-flow-rate aerosol particulate filtration of 95% while breathability maintains at Delta P 5.3 mmH2O / cm²

EU’s PPE mask standard EN 149 is very strict (more stringent than the US equivalent of N95), the air flow rate used in filtration tests is 3 times higher than that of the ASTM standard for surgical masks. EN 149 also implements a tight-seal leakage test. However, there is no specification for breathability. So while PPE respirators are usually more protective than surgical masks, they are also very difficult to breathe in! At masklab, we reduced the oil-based aerosol filtration rate, which we believe to be less important in the pandemic, to 85%, thus enhancing our breathability to Delta P 5.3 (generally KF94 masks are above 9.0) Our overall level is FFP1, but our protection against viruses is actually FFP2 level.

Many people may wonder: Oil-free high-flow-rate aerosol particulate filtration of 95%? Does that mean respirators are less protective than Level 2 or Level 3 surgical masks?

The answer is: No, absolutely not. Quite the opposite.

First, the test flow rate used by EN 149 is 95 L/min, while ASTM Level X uses 28.3 L/min. Many surgical masks with more than 95% PFE would test to be less than 70% under EN 149 parameters. The main reason is that the efficiency of the filter material is often affected by the air flow rate. The larger the air flow rate, the lower the efficiency of filtering particles.

Secondly, EN 149 implements a sealing test to ensure that the air leakage caused by the gap between the face and the mask will not exceed the standard. The masklab KF series have been tested to have a total inward leakage of less than 15%. This is not tested for surgical masks, so many of them have very high air leakage, which makes them more suitable for protecting others, not for protecting oneself.
