These award-winning filters feature JSP’s Press-To-Check technology, which allows you to quickly test the fit of your respiratory system each time you wear it by gently pinching the filter casing and closing off the air supply. You should then try to inhale; if when you do this, you can hear air leaking in or can breathe in still, this means you have a leak.

These filters feature an enclosed design that protects the filter medium from impacts and water splashes.
