YAMASHIN NANO FILTER®
Opens Up Infinite Possibilities of Filtration

An Ultimate Filter Made From
Ultra-Fine Nanofiber Material

What can our filters offer you?

High capacity,
Ultra-fine filtration,
Unobstructed breathing capabilities


Using Nanofibers manufactured by our patented production process, YAMASHIN has developed a unique specialized mask which provides protection from invisible airborne particles, allowing the user to breathe comfortably for long periods of time while maintaining excellent filtration performance.
 
Most disposable non-woven masks fail to provide protection on a microscopic level as the mask cannot filter out microparticulate harmful contamination matter such as PM 2.5 and viruses.

Having originally developed filtration technology for construction machinery, YAMASHIN filters collect Nano-sized particles. YAMASHIN NANO FILTER® maintains high efficiency for a long time so oil can pass through freely, lubricating and protecting the machinery.


"Like a Breath of Fresh Air in a Green Forest"


As leading experts in the filtration industry, YAMASHIN-FILTER CORP. masks and sheets have the ability to stop harmful particles and viruses from passing through them.
Our Nanolevel material research and proven reputation in oil and hydraulic filter products, has allowed us to supply over 70% of the construction machinery sector with filters and advanced filtration technology. (Reference. Yano Institute of Economic Research).
 
Our unique technology, gained through 65 years of research and development, is now being used in mask products for everyone who wishes to be remain healthy.

Technical Capabilities

Decorative and Cloth Masks Cannot Provide
Fine Particle Filtration like the Ultimate YAMASHIN Filter Mask™

Technical
Capabilities

While some disposable masks available for general hygiene purposes may have antibacterial properties, these masks do not filter out nano-level particulate contamination. This means these masks cannot filter out fine dust and viruses over a sustained period.

Using filtration materials made from the finest Nano fibers, masks and filters made by YAMASHIN can prevent even the smallest particles such as dust, pollen and viruses from entering the respiratory system.

Feature 1

"The ability to stop invisible
contaminates using a multilayer
3D filtration system"

The synthetic fibers in conventional disposable masks use a rough mesh to trap dust and viruses using an electrostatic charge. Ultimate YAMASHIN Filter Masks™ and Ultimate YAMASHIN Filter Sheets™ use complex technology featuring Nano level three-dimensional structures providing superb filtration performance. By weaving Nano fibers using our patented technology our masks can trap viruses more consistently over long periods of time. This Nanotechnology, developed by YAMASHIN, is so effective that it can be used in the medical field.

Feature 2

"Mask users are kept safe and protected with performance
lasting over 24 hours"

Most commercially available masks use static electricity to capture dust and viruses. Due to the buildup of moisture within these masks, performance drastically decreases over time. Our research has shown that this can be up to 65% over a 24-hour period. As Ultimate YAMASHIN Filter Masks™ rely on fibers that capture particles on a Nano level, filtration performance is only decreased by 9% over the same period.

"Upgrade your mask with
Ultimate YAMASHIN Filter Sheets™ to
improve performance"

Antibacterial inner sheets used with general commercial masks and disposable mask filtration efficiency can be improved. The Ultimate YAMASHIN Filter Sheet™ can be used with a variety of different masks and has superior filtration performance; catching the smallest of particles.

"Ultimate YAMASHIN Filter Mask™
and Ultimate Yamashin Sheets™ are
100% made in Japan by a company
established for over 65 years"

Around 80% of the general masks currently sold in Japan are produced overseas, which can lead to supply and quality issues. 100% of Ultimate YAMASHIN Filter Masks and Ultimate YAMASHIN Filter Sheets™ are produced domestically at our own factory in Saga prefecture. With our state-of-the-art machinery, and experience in manufacturing high performance filters for construction machinery, we have realized the distinguished production system of high grade nanofiber to meet our strict quality control standards.

Benefit 1

The uniquely developed
Nano filter is

the difference in performance

The difference in filtration lies within the unique Nano Filter technology developed by the world leading specialist filter manufacturer YAMASHIN-FILTER CORP. The Ultimate YAMASHIN Filter Mask™ and Ultimate YAMASHIN Filter Sheets™ ability to capture particles is overwhelmingly superior when compared to other commercial disposable masks.

Benefit 2

The majority of regular disposable masks

do sufficiently capture particulate contamination

Blocking pollen and fine dust can make day to day life more comfortable, however, trapping viruses is the type of prevention that truly maintains your health. This is especially important for those working on the front lines in the medical field.

Benefit 3

To ensure safety
and security
our products are

100% made in Japan


The filters are domestically produced in our own factory in Japan under the strictest quality control measures. This ensures that YAMASHIN filters can prevent impurities contaminating the product during the manufacturing and transportation process.
