Why is Ultimate Yamashin Filter Mask so special ?

High capacity, Ultra-fine filtration, Unobstructed breathing capabilities

Yamashin-Filter Corp. has developed a unique specialized mask using Nano fibers manufactured by their patented production process. The filter provides protection from invisible airborne particles , allowing the user to breathe comfortably for long period of time while maintaining excellent filtration performance.

It is capable of filtering out harmful microparticulate matter such as PM2.5 and viruses. Most disposable non-woven masks cannot achieve this performance and offers no protection to the user.

As leading expert in the filtration industry, Yamashin is currently supplying 70% of Japanese construction machinery sector with filters and advanced filtration technology.

With this unique technology and 65 years of R&D experience, they are using the filters for Medical grade mask production during the COVID-19 pandemic. Having originally developed filtration technology for construction machinery, YAMASHIN filters collect Nano-sized particles. Our YAMASHIN Nano Filter™ maintains high efficiency for a long time so oil can pass through freely, lubricating and protecting the machinery.

Filtration Performance of Ultimate Yamashin Filter versus Disposable Mask and Cloth Mask

Disposable mask is only good for blocking bacteria for general hygiene purposes. They do not filter out nano-level particulate contamination. Thus, unable to filter out fine dust and viruses over a sustained period.

Ultimate Yahashin Filter Mask is made of finest Nano fibers and can effectively blocked off smallest particles such as dust, pollen and viruses from entering the respiratory system..

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. YAMASHIN masks use complex technology featuring Nano level three-dimensional structures providing superb filtration performance. By weaving Nano fibers using their patented technology, Yamashin 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.

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. Yamashin research has shown that their mask performance can be degraded up to 65% over a 24-hour period. This is made possible as Yamashin masks rely on fibers that capture particles on a Nano level, filtration performance is only decreased by 9% over the same period of time.

Upgrade your mask with YAMASHIN Filter sheets to improve performance

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

Yamashin has PFE test results attached conducted by KAKEN Test Center in Japan. The PFE without washing was 99% while the PFE after 5-time washing was around 97%, still high.

YAMASHIN filter masks and 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 YAMASHIN filter masks and 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.
