Will the mask fit my face?
TOTOBOBO mask is made of very flexible material, together with the ergonomic nose profile design, it can adapt to many adult faces without modification. If it doesn’t fit your face, read on the following answer.

How do I ensure the mask fit my face and forms a good seal?
When a mask touches your skin, there is a seal where air can not go through. A continuous seal is necessary to form a complete loop to enclose the nose and mouth in order to prevent pollutants from leaking into the breathing zone. All face masks require a fit-test to validate proper face seal. However, in many practical situations, such as in an emergency or at home, either fit-test facility is not available, or it is too impractical and time-consuming. TOTOBOBO provides the best alternative called “Clear-Seal check”. Carefully examine the peripheral and underneath the mask; to check if a continuous seal exist surrounding your nose and mouth.
If the seal breaks at some point, it can be improved simply by adjusting the position and the tension of the strap.
If the mask is too big, trim the mask smaller to try again.
There may be a small gap around the nose bridge area. In this case, trimming away the edge that presses deep into your cheek will help to close the gap.

How do I know if the strap (loop) is the correct size?
For optimal comfort (e.g. woodturning), the strap can be adjusted to provide sufficient tention to hold the mask on your face, yet soft enough to allow exhale air to be released between the edge of the mask and the face.

for optimal safety (e.g. hospital), the strap should be tighten such that the mask maintain a good seal regardless of inhale or exhale.

How can I adjust the strap if it is not too loose or too tight?
You can optimize the mask wearing security and comfortable by adjusting the size of the strap-loop. To adjust the strap, press on the release knob on the adjustable clip. Adjust the starp so that it provide the suitable level of force.

open up the strap clip by pressing on the two little dots to release the catch. Fasten the clip after adjusting the strap.

Reuse of the mask

Do I need to clean or disinfect the mask for reuse?
For protection against non-contagious pollution, such as traffic pollution, dust or fine particles, there is no need to disinfect the mask. TOTOBOBO mask contains Silver ion, an anti-virus agent. This active agent limits the growth and slowly kills the bacteria or viruses chance on its surface. For most non-contagious situations, it is safe to reuse the mask after 24 hours of leaving it in a clean environment. However in situation that the mask may be contaminated with contagious viruses or bacteria, or when working in critical area in hospital (e.g. ICU), you will be required to disinfect the mask before it can be reused.

How can I clean/ disinfect the mask?
The mask can be disinfected by washing it with disinfecting soap, (like washing your hands), rinse it and letting it dry in a clean environment before reuse.

Do I need to clean/ disinfect the strap as well?
It is a good practice to clean /disinfect the strap together with the mask. Although the entire strap is on the outside of the mask during use, there is a part which can get very close to the eyes, if not careful, virus or bacteria may be on the strap may be accidentally transported to the eyes.

Filters

How do I change the filters?
Use the protruding lid to bend open the filter cap. Replace the filter inside, close and lock the filter cap afterwards. To minimize contamination, change the filter after cleaning/ disinfecting the mask. If that is not possible, change the filters in a clean environment and take care not to touch the inside of the mask during this operation.

How long does the filter last?
The effective usage time of the filter depends on a number of factors: – Concentration of contamination – Breathing rate – Heat – Humidity – Hygiene factors. These factors depend on your location and different environment. As a role of thumb, you should change the filters when the white filter turns grey. The filter should be changed before the particulate overloaded. It is recommended a filter should not be used longer than a month, even there is no signs of color change.
