Makes fitting and sealing much easier!
Poor face seal is poor protection. Over 90% of 1500 tests of N95 masks failed due to users unaware of the leaks, According to a published study by Tongji Medical College, which conducted 1500 tests with 500 N95 masks on 50 Chinese. To help identify any leaks, we developed the "water-mark" method; the frost internal surface of the mask turns into transparent when it touches wet skin. The transparent water-mark makes it easy to identify any gaps between the mask and the user's face. With Totobobo patented technology, ensuring protection and face seal is easy and accurate.
Not getting a good seal? No problem, let's warm it up with a hair dryer or hot water to ReShape the mask to make it fit better!
Is the mask too big for your kid? No worry, trim the mask to fit smaller kids (some cases down to 3 years old). You can even "test trim" with the "paper simulator".

1) Apply a bit of water on the user's face with cotton wool. Make sure the area where the mask touches the face are wet. 2) Put on the mask and check the "water-mark": 3) Refer to the illustration, where the mask touches the face, the frost inner surface of the mask turns transperent. Where there is gaps between the mask and the face remains frost. 4) The mask is totally sealing the user's face if there is a continuos transparent area encirculed the nose, mouth and chin area. 5) If the transparent loop is broken, you may proceed to improve the fitting of that area by "ReShape" method shown below.
This video shows how to use a hair dryer to reshape a Totobobo mask to improve the fit, especially to eliminate gaps near to the nose bridge. (1) Hold the outside of the mask, use a hair dryer to blow into the inner surface. Keep dryer moving to avoid overheating. (2) Switch off the hair dryer when the fingers holding the mask feel the heat through the mask body. (3) Use two finger to pinch the nose-bridge part of the mask inward, another hand to hold the chin area. Hold the mask in this position for 1 minute to let it cool down. (4) Release the mask. The mask is now moulded into a new shape. Try to see if it fits better.Any leaks between the mask and your face can significantly decrease the protective effect of a fitting mask.
