Totobobo 96% filter tested by Nelson LabsTesting Totobobo mask against 3M N95 masksTo validate the protection of Totobobo, we sent the masks to the Prince of Wales Hospital in Hong Kong to test the effectiveness by professional fit-test facilities.The test report was recently published in the Journal of Hospital Infection. The objective of the test was to compare the efficacy of Totobobo aganst N95 masks (3M 1860 or 1860S or 1862). The test was conducted in 22 healthy volunteers. Note that all test subjects have previously passed fit-test of N-95 mask but all are first time trying the Totobobo mask. The key findings are:

The layman filter testThe filter is the most important component of a respirator. The quality of air that gets into your lung is determined by the quality of the filter, provided you there is a good seal between the mask and your face. To find out how effective these different alternatives are, a laser particle counter is used to collect objective data.Protection factor (P) of each filter is calculated by the formula: P = Qi / Qn Where Qi is the value of ambient particle count without filters and Qn is the particle count of the filter concerned. Higher P value indicates better protection factor. Protection factor (higher better)
Totobobo is the best anti-pollution mask providing N95 class performanceTotobobo mask is the most comfortable and advanced respirator in the non-certified respirator market. In many respects the patented design is revolutionary. The original design cater to the needs of common users, who do not have access to professional fit-test facility and yet need the assurance of a well fitted respirator.Tests shown that Totobobo mask is significantly more protective than any anti-pollution mask available in the market.A different approach To provide assurance of good fit, we made the reusable mask with transparent plastic, so that users can see through and check the face-seal. We also make the mask customizable, so that users can trim the mask to fit their face. The thin and flexible plastic is highly adaptive and easily follows the contour of the face, it is exceptionally flexible and comfortable to use. There is even silver ion anti-virus additive in the mask to make reuse more safe. all these sounds great on paper, but how does it perform in real life? Bottom line:If your have access to fit-test facility and have time to conduct fit test, the best option is fit-tested N95 mask. Otherwise, Totobobo mask provides very good protection even if you don't have access to fit-test facility or in emergency and there is no time for fit test. |
