FAQ | COVID-19, Coronavirus

Is the Totobobo mask/ filters effective against coronavirus?

To reduce the risk of viral transmission, we recommend using our F96 or F94 filters. Our Totobobo filters have been tested and certified for their filtration efficiency, and you may refer to the chart of the latest test reports by Nelson Labs at  
Additionally, for sports use, we recommend our new PRO filter, which provides N99-grade performance while allowing easier breathing.

How long can the filter last?

For air pollution purposes, we recommend replacing the filters every two weeks or when the filter turns from white to mid-grey, as indicated in the reference picture on the packaging. For virus protection, we suggest replacing the filters after one week of normal use in low-risk areas such as shopping malls, offices, and public transport. If you use the filter in high-risk areas such as crowded hospitals or clinics, you should replace it immediately after use.

How should we handle and clean the filters and the mask after use?

To maintain hygiene and effectiveness, wipe the mask with alcohol or antiseptic after use, taking care not to touch the filters. Leave the mask in a well-ventilated area, ideally with exposure to sunlight, to dry and disinfect.

When changing the filters, dispose of them safely and wash the mask with soap and water. Before taking out the new filters from the packaging, clean your hands thoroughly to prevent contamination.

Is Totobobo mask same as N95 mask?

The Totobobo mask has some similarities and differences compared to a typical NIOSH-approved N95 mask. A pilot study published by the Prince of Wales Hospital showed that the Totobobo mask was able to fit more people than the N95 mask (70% vs. 40%), which is crucial for providing effective protection. However, when the mask is well-fitted, the N95 mask offers a higher level of filtration efficiency than the Totobobo mask, scoring 193 vs. 133 (out of 200) for particulate filtration efficiency, where higher scores indicate better performance. Both types of masks have their respective advantages and disadvantages, and the choice ultimately depends on the specific needs and preferences of the user.

Totobobo and surgical mask

Surgical masks are primarily designed for one-time use during medical procedures to protect both the patient and the healthcare provider from potential contamination. However, for individuals using surgical masks in less critical public settings, such as shopping malls or public transport, the risk is typically lower than in a surgical theatre, and many people reuse their surgical masks without significant problems. However, surgical masks are loose-fitting, and air can still escape along the sides of the mask, providing less protection compared to a well-fitted N95 or Totobobo mask.

The Totobobo mask, on the other hand, is designed for long-term use and can be cleaned and reused, providing a better fit and a higher level of protection against airborne particles. We recommend changing the Totobobo filter after using it in high-risk areas, such as crowded hospitals or clinics, and wiping the mask body with alcohol after use while avoiding touching the filters. Leaving the mask in an open, well-ventilated area, preferably under sunlight, can help to disinfect and dry the mask. For normal daily use in low-risk areas, the Totobobo filter can be safely reused for up to one week. It is important to dispose of the filters safely and wash your hands before installing new filters to prevent cross-contamination.

Overall, while surgical masks are suitable for certain situations, the Totobobo mask provides a more secure and cost-effective solution for long-term protection against airborne particles in various settings.
