Best reusable mask
Totobobo mask comes in two sizes (L and M/S),
Large size is suitable for most man.
Medium/small is the same mask and is suitable for most women out of the pack. To obtain smaller sizes, you can trim the edge of the mask away.
You can use the Size chart for a quick check.
If you need more accurate size estimation, please download and print this template to make a simple paper dummy mask. That allows you to check and compare the two sizes physically.
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.
How to use hot/cold water to shape a Totobobo mask to suit your face?
This quick method is especially useful to open up the mask and provides better seal around the nose bridge and the chin.
A short video on how to shape your Totobobo mask using hot (70°C) and cold water. Getting a good fit is key to effective respiratory protection. For airborne contamination such as virus or PM2.5, you want the air to go through the filters, not the gaps. The Totobobo mask can be mould and re-shaped many times, until you get the shape best fitting your face. Here is a short video demonstrating how to shape the mask in under one minute. (Warning: maximum temperature is 70°C, over-heat can damage the mask) (Warning: Do not mould the hot mask directly on the face!)
