Awesome Seal Check!

Makes fitting and sealing much easier!

Easy Seal Check

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.

ReShape the mask

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!

Trim the mask

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".

FAQs (Filters)

The effective usage time of the filter depends on a number of factors: – Concentration of contamination – Breathing rate – Heat – Humidity – Hygiene factors, and your environment. As a role of thumb, you should change the filters when the white filter turns 50% grey as printed on the filter packaging. On the other hand it is recommended the filter should not be used longer than 2 weeks, even there is no signs of color change. More detail discussion (here)
F96 (96%) filter - Extra high level of protection. Breath easier than typical N95 masks.
F94 (94%) filter - Easy to breathe while maintaining high level of protection.
F92 (92%) filter - Most economic, high efficiency for everyday use.
All above filters contains electro-static charges and is highly effective to trap fine dusts and particles even below 0.3 micron.
The electro static force embedded in the filter media is very strong and will not lost it function after contacting water. However, the filtration efficiency will slowly decrease gradually. We recommend to replace the filter after 2 weeks of use, or when it changes to 50% grey, as indicated on the filter packaging.

How to ReShape Totobobo mask?


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.
