On April 2, local time, when US President Trump was asked at the Novel Coronavirus Epidemic Press Conference whether Americans should wear masks to protect themselves from Novel Coronavirus infection, he replied, "If people want to wear a mask, they can wear it. In many ways, a scarf is better. Becauseit is thicker."

A scarf that is thicker than a mask, so will it protect against viruses just like a mask? GBPI uses the self-produced Face Mask Particulate Filtration Efficiency Tester to detect the scarf to see if the scarf can meet the standard in terms of particulate filtration. GBPI's Face Mask Particulate Filtration Efficiency Tester is used to test the particulate filter efficiency of daily protective masks and medical masks, and to determine the obstruction performance of ordinary fabrics and medical protective masks for constant flow of airflow.

Test item one:

Sample: Disposable medical mask

Experiment procedure：

Mask experimental results: The filtration efficiency of the mask is 96%.

Test item two：

Sample: Scarf

Experimental procedure： stack a plush scarf into two layers for experiment

Experimental result of scarf: The filtration efficiency of the scarf is 76%.

The test results of GBPI's Face Mask Particulate Filtration Efficiency Tester: the filtering effect of the mask is 94%, and the filtering effect of the scarf is 76%, which shows that the two-layer thickness of the scarf can not achieve the filtering effect of the mask.

In addition to Face Mask Particulate Filtration Efficiency Tester, our GBPI mask testing instruments also have Mask Bacterial Filtration Efficiency (BFE) Detector 、Disposabel Medical Mask Respiratory Resistance Tester and Multifunctional Tensile Tester for Face Mask, etc. These instruments can greatly improve the pass rate of mask production quality.
