ABOUT CAMBRIDGE MASK PRO

Engineered with UK military-grade filtration technology,

Cambridge Mask respirators are half-face masks

classified as personal protective equipment (PPE).

Cambridge Mask PRO is a fashion focused pollution

mask that comes in a large range of designs and 5

different sizes to fit comfortably for both children and

adults. Cambridge PRO provides nearly 100% protection

from particulate pollution such as PM10, PM2.5, and

PM0.3. Boasting a unique triple layer filtration system, the

PRO mask also filters out 99.7% of bacteria and 99.6% of

viruses from the air.

1.The Primary Filter Layer

The first layer of the mask designed to filter out large

particles such as dust and PM10.

2.The Three-Ply Micro Particulate Layer

The second layer of the mask blocks particulates such as

PM2.5. It also filters 99.79%+ of particles as small as

PM0.3.

3.Inner Filter

The inner filter is made from a 100% pure activated

carbon cloth which was originally invented by the UK

Ministry of Defence. The Military Grade Carbon Filter –

traditionally powders and granules – generate “Van der

Waal” forces due to their porous structure. These forces

give activated carbons their unique potential to adsorb

gaseous molecules, including anions and cations into

their internal pores.

1. Step One:

Using a tape measure, measure from the mid-point of the

user nose to just over an inch under the chin, this would

be the reference for the first number on our size chart.

2. Step Two:

Measure from the outer edge of the user left cheekbone

to the outer edge of the user right to cheekbone (about an

inch below the temples) to find the correct width for the

mask. Make sure to add a couple of millimeters to the

user measurement to avoid mask being too small.
