Fit and Seal Testing

Testing the fit and seal of your respirator is essential. Every face and head is unique, and what may work on one person may not work on you. Because of this, it is crucial to inspect and leak-test your mask prior to use.

To check that the seal on your mask is sound, you will need to perform a negative pressure test. To do this, cover the front filter port with your hand so that no air can flow through it to your mask and inhale.

If you feel immediate pressure on your face, and your mask sucks inward on your face like air out of a bag, your seal is perfect. If this doesn’t happen and/or you feel air rushing in from somewhere in the mask, you have a leak in your seal that needs to be remedied.

Seal leaks can be resolved by adjusting the placement on your face, tightening the head harness, and ensuring identifying hair/ facial hair is not breaking the seal line. If none of this works, you might have to change the size of your mask.

Excellent product which just may save my wife & my life!

A very well made product designed for a specific task.


actually happy with product...great vision, sturdy and fits well (I got the L size) My only comparison are the fire masks at work and altho I haven't attached a canister to this one yet I feel this mask is 10 times more comfier. I am pleased I bought this as a safety net not only for chemicals but simply to wear if I am trying to leave a fire zone again just so i don't breath in the smoke. It gives me peace of mind having it in my ute. My only criticism is for the price it should come with a protective container/bag instead of just a piece of bubble wrap to protect it long term.

This mask works a treat!

I install timber fences and the worst part of the job is trimming the tops off the palings as saw dust goes everywhere!
Breathing the Copper Chrome Arsenate saw dust also irritates my nostrils so this mask is the ultimate solution to the problem.
No saw dust in my eyes and nose anymore!
Breathing takes no effort at all unlike the cheaper tradesman type of masks that also fog up glasses and visors.
