The mask can be washed with soap and hot water, however, keep in mind that this will not extend the life of the filters.

:: Fit ::

Fit is perhaps the second most important aspect of any respirator. It might not seem like it initially, but a perfect fit is vital.

If a respirator does not create a seal on your face particles such as fine dust, bacteria, and viruses can avoid the filter and enter around the edges. 

This means that the air (that comes through the sides) is not actually being filtered. While you may receive some protection, you will not receive the full extent that the mask can offer. 

For this reason, achieving a good fit is essential. Luckily, this is one of Cambridge Mask’s strengths.

Cambridge Mask follows the standard reusable mask formula, a filter with a valve and ear straps. However, it also has one bonus that is one of its greatest appeals.

That is the chin straps that the Cambridge Mask Pro has. Unlike other ear-strap respirators, the Cambridge Mask features two adjustable straps on either cheek.

These straps are elastic and create a strong seal around the chin. With the current global situation, these straps are extremely handy.

In times such as this, it’s vital not to touch your mask. However, the adjustable straps give you an easy way to adjust the mask without touching the filter or ear-straps. 

The Cambridge Mask also features the wire nose-piece that is standard in most respirators. 

:: Sizing ::

How to:

Either use the weight range as a guide 


Use a tape measure

First, measure from the middle of your nose to about a little over an inch under your chin, this would be your reference for the first number on our size chart.

For the width can be tricky, as human nose have different in size. So make sure to add few mm to your measurement to avoid mask to be too small for your nose or you cheek.

Second, measure from right cheekbone to the left, for the width of the mask. Make sure the tape sized correctly. You may use mirror or other’s help to be accurate while measuring.
