Some of our user’s feedback stated that it would be great to add a nose clip to the Totobobo Mask, especially for people with a prominent nose. These users are experiencing small gaps between the mask and their nose’s bridge. However, a nose clip is not a reliable solution in the long run for reusable masks. Prototype testings have showed that the clip breaks or loses it’s rigidity after repetitive bending and will break eventually.

The following video shows how to re-mould the Totobobo Mask, using hot and cold water. The hot water helps to soften the body of the mask, while the cold water helps to harden the mask after reshaping it to the desired shape. This method can be done over and over again, there fore, making it a more reliable solution.

The heat treatment can be applied to any parts of the mask (e.g. the chin), not only the nose area. The possibilities are limitless. You may need to try moulding the mask several times to achieve the best fit.

 

Moulding feature further enhances protection and comfort for the user.

Better face fitment = lesser gaps = better protection

PM2.5, a very fine airborne particle, is smaller than 2.5 microns which can be inhaled and travel deeply into our lungs, which will then enter our bloodstream. These particles causes micro inflammation and hardens our blood vessels. Recent studies have showed that the PM2.5 not only triggers diseases in our lungs and other respiratory organs, but also triggers cardiovascular diseases and strokes. Common surgical masks or even a poor fitting N95 mask won’t be of much help due to the cunningness of the PM2.5. Ensuring a secured face fit is the first fundamental step towards respiratory protection.

Totobobo Mask have three key features to aid you in obtaining a optimal face fit.

  1. Sizing : Totobobo Mask is the first and only mask that allows its user to cut to fit. You don’t have to risk over cutting the mask. Download this template to test the size using a paper dummy first, before proceeding to cut the actual mask.
  2. Fine tuning with heat moulding : The heat moulding process makes it possible for the user to fine tune the fitment of the mask. Small gaps around the nose or under the chin? No worries! Just re-mould the mask and you’ll be able to eliminate, or at the least, minimize these gaps. You can re-do this step as many times as you like! Remember to not use boiling to re-mould the mask, otherwise you’ll risk destroying the mask. Use warm to hot water around 80C instead.

Another point to note, a small gap occurring during exhalation does not affect the effectiveness of the protection, in fact, it may be beneficial as it helps to release exhaust gases quickly. What you need to check is whether the seal is closed tightly when you inhale, due to the negative pressure while inhaling. Ideally, you should adjust the straps so there there are small gaps to speed up exhaling and feeling comfortable at the same time.

    Visual Seal Check (VSC) : Using the transparent property of the Totobobo Mask, you can check if the mask is touching the areas below the chin, forming a good deal. If the seal is not optimal, you may fine tune the cutting and moulding of the mask, or simple adjusting the position and tension of the strap to get a better fit.

Wearing Comfort

If a mask is not comfortable to wear, the user will use it less often, so the chances of it being functional is generally lesser as well.

The heat moulding adjustment allows the mask to be re adjusted to fit your face profile closely. A good fit is beneficial as it not only provides a good seal, but you’ll also feel more comfortable wearing it and also not forgetting, you can loosen the tension on the straps as well. During exhalation, the internal pressure pushes the mask and forces the seal to be broken, releasing the air quickly. During inhalation, the process creates a “sucking” motion due to the negative pressure, which closes up the gaps, forcing air to enter only by the filters. The Totobobo mask functions like a one-way valve, without it being a valve physically. Some users described it as “The mask is breathing with me.”
