Overview of the Fit Testing

    WSD-9501 face mask must seal to the wearer's face in order to provide expected protection. Therefore, fit testing needs to be done prior to first use and must be assessed at least annually. In addition, fit tests should be performed:

1. Whenever a different size, style, model or make of respirator is used.

2. When any facial changes occur that could affect fit, such as significant weight fluctuation or dental work.


Instructions of the Fit Testing for WSD-9501 KN95 Face Mask

    Qualitative Fit Test (QLFT) is highly recommended due to it's convenience and effectiveness for most wearers.

    QLFT is pass/fail and relies on the user's senses using 1 of 2 test agents listed below:

1. Saccharin (sweet taste); can test respirators with a particulate filter of any class.

2. Bitrex® (bitter taste); can also test respirators with particulate filters of any class.

    Each QLFT method uses four exercises performed for 1 minute each:

1. Normal breathing.

2. Deep breathing.

3. Moving head.

4. Talking.

    In the QLFT, the test subject may detect a sweet or bitter taste if the respirator is not fitting properly.
