Nomad Travellers test Totobobo Mask

Davide and Oti reminds me of Herves and Goska. Both team were of Nomad Travellers

While in Singapore we were lucky enough to be accepted by Mr Francis Chu to visit Totobobo mask’s headquarters in Singapore and get to test live some samples of his invention. We were able to understand a little bit better the working mechanism of their product, how to properly wear the masks and how they perform compared to some of their direct competitors: Respro mask and 3M N95 disposable mask (1860s).

Arriving at Totobobo mask’s headquarters and getting to know Mr Francis Chu

After wandering around Totobobo’s neighborhood lost in between big commercial blocks, we eventually manage to decipher the coded Singaporean address we were provided, and to access the clean and professional looking headquarter of Totobobo.
We introduced ourself to the creator of Totobobo Mask, Mr Francis Chu (I forgot to ask him where Totobobo’s name is coming from) and we soon felt a good connection with him: ahumble, positive and friendly person.

What is Totobobo mask?

Totobobo mask is a reusable mask made of a non allergic elastomer, that uses replaceable filters and unique technologies. It is sold at the moment for 33 USD.

The peculiar characteristics of this mask are that it can be modeled using heat to fit perfectly everybody’s face, and the “Watermark Seal Check“, a technology that helps understanding when there are no gaps between mask and skin, by turning the frost internal surface of the material into transparent.

When there is a continuous transparent line in the contact interface face-mask, then a perfect fit is obtained.

The filters available come in 3 different grades: N96, N94, N92. The number basically indicate the percentage of particles over pm 2.5 that are blocked by the filter.
The most effective filter of the line, the N96, would block at least 96% of the contaminants. While it is more performant, it can make more difficult the breathing operation and it’s more expensive than the others, so that while some customers might prefer the most effective option, others might find more convenient the N92 filters.
Totobobo mask comes in different sizes, and can even be trimmed to fit smaller faces.

Using Totobobo mask

Mr. Francis started our educational visit by showing us how to use his product.
The main operations that can be performed are:
– modifying the shape to perfectly fit the contour of the face;
– correctly wearing and adjusting the mask;
– replacing the filters.
There are plenty of tutorial and videos on their website on how to do that. That’s where I suggest you to go for a more detailed explanation.
Heat is needed to reshape the mask, and it can be provided by an hair dryer or hot water. Thesuggested mixture to obtain the perfect temperature is 3/4 of boiling water and 1/4 of room temperature water.
After warming up the masks for a few seconds by immersing them, the elastomer becomes softer and it can be reshaped until it gets cold (a matter of a few seconds) and “freeze” in the new shape.

It is actually easier said than done, and the whole process needs to be repeated several times after verifying the watermark until a perfect fit is found.
The first time it can get frustrating, and it might take as long as one hour of trial and error until a satisfying solution is found, but don’t give up! A perfect fit is ESSENTIAL for the efficiency of the mask!

TIP: You better exaggerate the deformation you want to impress, since after releasing the mask, it will partially go back to the previous shape.
You can also help yourself with tools, like a pen to wrap the mask around for the top tight curve of the nose, or a flat desk to flatten an angle.

Reshaping Totobobo maskReshaping Totobobo mask

It’s possible to adjust the length of the elastic straps, by wrapping them around the plastic holders.
Reposition of the mask should be better done by pulling it in front and placing it back on the face, rather than pushing it to fill the gaps. If repositioning doesn’t work, it means that it needs more reshaping.

Changing the filters is extremely easy, it’s just about releasing two elastic bands, removing the used filter and placing the new one into place.

Testing Totobobo mask and its competitors

While at the Headquarter we had the chance to do a lab test analyzing the efficiency of Totobobo’s mask and 2 of its competitors.

Totobobo was the winner with a reduction of 200+ times, 3M N95 reduced the pollutants around 30 times, and surprisingly Respro mask only 3 times!
We have written a separate article with the detail of the test and photos of the result: Comparison of 3 anti-pollution mask models.

This test was so educational for us. We understood how important is to find a perfect fit of the mask (Not only Totobobo, but any mask!) and that we were basically wasting time in Indonesia when wearing our simple Surgical masks.

Totobobo’s packaging and enviormental approach

The packaging of Totobobo mask is really minimalistic and completely recyclable.
Fancier, more sellable packaging have been discarded to reduce at minimum the waste created by the product: Mr Francis preferred to stick to his environmental beliefs, rather than selling a few more masks.
The plastic bag of the case is actually a zip-lock bag, that can be easily reused.
Also the filters packaging uses a similar zip-lock bag, and contains a single simple paper presentation with an image to be used as a reference to understand at what moment to replace the filters, e.g. when they reach a 50% gray color (but no later than after 2 weeks).

Totobobo and cyclists

Totobobo mask is s cyclist friendly product, not only because cyclists are one of the major supporters, but also because Mr Francis is a cyclist himself and the only extra bit of paper in the packaging is a nice heart shaped recyclable note addressed to car drivers, asking them to respect cyclists since they are making the air less polluted also for them.
By the way drivers! Some studies shows how pollution inside the car can get even higherthan the one outside, since somehow it gets stuck in the cabin: so car drivers shouldn’t thing that masks are something only for cyclist or pedestrian and that they are immune to the pollution that they are creating!

Cons and possible improvements of Totobobo mask

While the mask works amazingly when perfectly set up, the learning curve to understand how to reshape the mask is quite steep, and we are scared that some people might get frustrated and misuse the mask or just give up.

While wearing the mask in warm and humid tropical climate, there is condensation inside the mask, that can feel annoying at the beginning.

That’s a common problem to several masks, and to solve it Totobobo propose the possibility to trim the mask to the “SuperCool” design covering only the mouth, so that exhalation can be done through the nose with no condensation. This design is particularly suggested for cyclists that wants to inhale more air using the mouth instead of the nose.

As a secondary cons, we realized that the look of the mask is so unique, that many people were staring at us. Some people might feel uncomfortable and stop wearing the mask. A suggestion is to propose a customization pack with a thin personalized cover to put on top of Totobobo mask, or if you feel uncomfortable just wear a cheap standard mask on top of Totobobo’s.
In any case we of course prioritize our health over our look.

As a suggestion for the future we would also like to see a “family pack” with maybe 50 filters at a discounted price, to decrease the operational cost (already quite low compared to other brands at around 2-5$ per month) for people permanently living in polluted places and to also reduce transportation costs-emissions and packaging.

Our final conclusion

We have started using our Totobobo masks, and changed the filters for the first time after 7 days of usage in Malaysia, plagued by the haze coming from Indonesia. So far we are satisfied, it works well and the filters are getting gray as expected!

We are so grateful to have met Mr. Francis Chu and directly experience the lab tests on the masks! Now we understand much better what are the important parameters to choose an effective pollution mask, and how to correctly wear it.
At the end of our visit to Totobobo’s headquarters, we were happy to support their productsnot only because they are effective, but also because we believe in Mr Francis mission and we liked a lot his approach of doing business, not putting money and success as the main priority if it’s colliding with higher purposes.

Dr. Hewitson’s advise on air pollution for Taiwanese

Update 2021-01-20
Dr Justin Hewitson just posted a funny and educational youtube about wearing a mask in Taiwan:

A recent purchase from Taiwan triggered my curiosity. I ask the customer, Dr. Hewitson, why he choose Totobobo mask. His answer surprised me. I didn’t realise the fact that healthy non-smokers in Taiwan are much more likely to get lung cancer than smokers in the USA!

“As I’m in a research institute here in Taiwan, some of my colleagues have done studies on the effects of air pollution on both the lungs and the brain of mice.
As it stands, people in Taiwan who do not smoke are three times more likely to get lung cancer than smokers in the United States. Many Taiwanese are not aware of this. I am constantly educating my students on the dangers of air pollution and actually I recommend your company to them all the time whether or not they purchase, is another question but I have faith in what you guys are doing.”

By Dr. Justin Hewitson

The study:
Higher than Usual Lung Cancer Incidence in Taiwanese Non-smokers

An ongoing study suggests environmental factors in Taiwan are contributing to a rising number of cases in otherwise healthy non-smokers.

After four doctors at National Taiwan University Hospital (NTUH) had suddenly collapsed on the job during the previous two years – with one of them failing to recover – the hospital in the second half of 2013 ordered all staff physicians 45 years of age and older to take a physical examination.

The comprehensive health checks included low-radiation computerized topography
(CT) scans of the lungs. The results were chilling. Of 300 physicians tested, 12 (4%) were found to have a small lung nodule (less than 1 centimeter), which subsequent testing confirmed as lung carcinoma.

The study on lung cancer in non-smokers is groundbreaking because it highlights the risk that the disease poses to the wider population. For decades, lung cancer has been associated almost exclusively with cigarette smoking. 

In Taiwan, non-smokers may be at a much higher risk of developing lung cancer than in the United States. The ongoing eight-year study has found that non-smokers here are twice as likely to develop the disease than are heavy smokers in the United States and Europe.
