A collection of video and graphics demonstrating how to make the most out of your Totobobo mask.
Standard Totobobo Mask
Step 1, adjust the earloop (compulsory step)
The tension of the earloop is very important. The earloop provide various means to adjust and fine tune the tension for a comfortable and secure fit. The earloop is a large elastic O-ring which can be separated from the mask by unwinding it from the filter.
You can adjust the earloop in 3 ways (illustration above):
- by looping it below the filter , this will reduce the length of the earloop significantly
- by looping it between the two “little wings”, this is to reduce the length moderately.
- by looping around one “little wing”, this will reduce the length slightlyHere is a video showing how these looping method can be done:
The little plastic piece is an adaptor to convert earloop into a head-strap style. Some user prefer that but most prefer just the earloop. Here is an illustration on using the adaptor

The video below shows how to adjust the earloop from loose to tight.
Step 2, Check the seal (Watermark seal check : Patented method)
The frost edge of Totobobo mask will turn to transparent when it touches water. This transparent area is call the watermark. You can use the watermark to check if the mask is making a good seal on the user’s face.
Follow these steps to perform a watermark seal check
- apply a layer of water on face
- check the watermark after putting on the mask. The frost edge changes to transparent where the seal happens.
- a good seal is achieved if the watermark encircles the nose and mouth. The mask can be used.
- The seal is not completed if there is a leak along the watermark. Try shifting the mask up and down, and then check again.
- If there is still leak, try ReShape the mask with heat (70C hot water, or use a hair dryer).
Step 3, ReShape the mask (if necessary)
Totobobo mask can be ReShaped, or moulded into a new shape to fit individual face. The new shape can be retained for a long time if it is kept in a loose pouch when not in use. Follow these steps to ReShape your mask (only if necessary):
- Soften the mask in 70C water, or use a hair dryer to warm it up gradually. (Warning: overheating will damage the mask permanently)
- Fix the new shape with your hand and fingers as shown in the above diagram.

Step 4, Trim the mask (only if it is really needed)
If the user’s face is too small to form a good seal with the small mask, you can trim the mask small to improve the fitting. From experience, children from 5 years old should be able to get a good fit. Totobobo mask may also fit younger children below 5 years old, which depends on individual face size and shape. The youngest kid we have been able to get a good fit is 2.5 years old!
Steps to trim the mask:
- Try cutting the “paper mask” to get a size matching the user’s face.
- “Paper mask” can be printed many times, therefore very suitable for the experiment.
- Cut the Totobobo mask, using the cut paper mask as a template
- Put on the mask, check if the size is OK
- Perform Water Seal check
- If necessary, ReShape the mask to improve the seal
- If necessary, cut the mask again.

How to upgrade to PRO99 Filter?
Video showing how to upgrade Totobobo mask with PRO99 filter. This upgrade is reversible, you can switch back to old filters during the less demanding days. Don’t throw away the old filter covers and the small rubber rings, they will be useful when you want to change back.
