Our KN95 face mask (also know as the KN95 respirator) has four layers, and is foldable, and once folded can easily fit in to a pocket or bag. The masks have been tested for fluid resistance, filtration efficiency, flammability and biocompatibility. They are designed to capture at least 95% of particles measuring a median of 0.3 µm, and as nanoparticles mainly travel by Brownian motion, they are effectively captured within the KN95 mask filter via electrostatic and mechanical forces.
What Makes Our KN95 Face Masks Stand Out
Unfortunately when it comes to face masks, not all masks are equal, no matter what they look like. It is a very sad, but true fact, that many of the new manufacturers of KN95 face masks (set up in China once they returned to work from the Coronavirus pandemic) are not honest, and are shipping below par products using either faked certification, or have produced high quality samples to gain their certification, but are then producing cheaper face masks with a cheap melt blown layer – see below.
The KN95 masks consist primarily of 3 main parts:
- The outer breathable fabric, which can be coloured (usually blue)
- The inner skin facing fabric, which helps to prevent skin irritations
- The melt blown layer, which is the most important and expensive part
The melt blown layer is a process that converts polymer resin into low diameter fiber non-woven web. As a minimum requirement for the mask to be effective, the melt blown layer needs have a 90% micro filter. As the melt blown layer you use increases in price the higher the percentage, many of the new companies are producing face masks with either a very low percentage of melt blown layer, or non at all.
It is impossible to tell without testing the face mask what the melt blown percentage is. However at PPE Guarantee, we have a very strict quality control team in our factories, and you can be assured that our KN95 face masks are the highest quality available.
Use of KN95 Face Masks
KN95 face masks are designed to be a single daily use item. The mask can be taken on and off throughout the day, and then disposed of on a daily basis. They are perfect to be used in public environments including walking and travelling to and from work on public transport, during shift work in warehouses etc, and in customer facing jobs such as in shops, offices and hands on jobs including builders, window fitters, locksmiths etc. It is highly recommended that the KN95 mask is used in conjunction with our CE certified safety goggles or face shields.
