3 reasons why Totobobo Masks is the best for children!

“Totobobo is far superior to any other mask on the market. Period!”

-Debbie Witte @ www.freehelpforcancer.com

Filter + Face seal = Good Protection

principle of respiratory mask protection

The basic principle of any mask is very simple: Isolation (Proper Seal) and Filtering. The function of the mask is to force all the air entering the breathing zone through the air filters. This can only be achieved if the mask form a good seal with the face.

“Good protection is built on two factors: a good filter and a good seal“.

 

Surgical Masks are not good enough for airborne contamination 

Surgical masks were designed to reduce the spread of germs from a patient, it is not designed to prevent air-borne contamination from entering the bodies. There are numerous gaps between the mask and the user’s face, allowing viruses or pollutants to pass through easily.

Surgical masks were designed to protect nurses and surgeons from blood contamination during an operation. In Japan, it’s common use was to reduce the risk of passing the Flu virus around by the wearers. 

N95 mask effectiveness: Fit Testing is a problem.

Respirators, on the other hand, were designed to protect the wearer from airborne viruses. This is possible if the respirator provides a good seal on your face, making sure that the air you breathe, will only pass through the filter(s) before entering your respiratory system. A proper fit test can be conducted by a trained specialist with proper equipment, which is usually inaccessible for the public.

Some manufacturers suggest a “User Seal Check”, which is performed by blocking the filter(s) while blowing into the mask to feel if any air is leaking from the sides of the mask. Such practice is questioned by a study from the Price of Wales Hospital in Hong Kong. The study showed a 25% failure rate when trained users applied the “User Seal Check”. This technique recommended by most manufacturers is too ambiguous and unreliable. “It’s usefulness as a pre-use test must be questioned.”, the study concluded.

Another large scale study, “Fitting Characteristics of N95 Filtering-Facepiece Respirators Used Widely in China” found that over 90% of the participants were not able to pass the fit test as required by the standard.

While looking for a respirator to protect his children, Francis Chu, the inventor of Totobobo Mask, encountered the same frustration as all the other parents. He became aware of the many difficulties that parents faced and determined to come up with a solution for everyone. He applied his expertise in product designing and experimented with hundreds of prototypes, before coming up with an ergonomic design that fits most users and more importantly, customisable and children friendly. He understands that apart from good seal and filtering, other factors like comfort, cleaning, reusing and portability are also important points to be considered before the product can be considered “Child Friendly”.

Following is a summary of how Totobobo Mask solves the common issues relate to mask wearing:

3 Reasons why Totobobo mask are superior!

Problem 1: Difficult to check for a good seal |  Totobobo solution: Watermark visual Check makes it easy

Totobobo mask is transparent, for a good reason. Most masks are made of opaque material, it is not easy to determine if there is small leaks between the face and the mask. Totobobo mask solve this issue with a simple method to visualise the seal and the leaks. Through the transparent mask, the user can easily check the seal with a bit of watermark. First the user wet the face with a dampen cotton wool. Where the mask touches the skin, the frosted surface turns into transparent, immediately indicating a good seal.

Problem 2: Reusing dirty mask |  Totobobo solution: Anti-virus, easy to wash, clean and dry

Disposable N95 masks and cloth based mask gets reuse for some times. The contamination and germs accumulated on the mask after each use can be a thread to health. Disposable mask cannot be wash, and cloth based masks are not easy to dry after wash. Totobobo mask is made of a soft plastic with embedded anti-virus silver ion. The Silver ion agent stop the grow of germs and the mask is easy to wash clean and dry for immediate reuse.

Problem 4: Different facial sizes |  Totobobo solution: Trim to fit smaller faces

Childhood is a fast growing period, their face size change rapidly and extends a wide range. To address this size range, most manufacturer come up with different sizes, such as S,M and L. However, it is not easy to determine which size before you open the package and try the mask on your kid’s face. Most shop don’t accept returned product due to personal hygiene consideration. The unique solution that Totobobo mask offer is to allow the use to trim the mask according to the size of the face. You can even download a “Totobobo mask simulator” to construct a paper model of the mask to test the cut and the sizing before you purchase.

Parents and school teachers from different parts of the globe have discovered this new solution for their children and students. If you are looking for an effective Respirator to protect your children, Totobobo Mask is exactly what you are looking for!

A true example:

After Chemo, Kayla’s Immune System is still compromised. This mask is our safety net that has proven its workability.

“When Kayla did not have the mask and went to school, she ended up in the hospital for two weeks, every month, for three months, a total of 45 days. With the mask, she had no sickness, no hospitalizations, no colds, nothing.

Your mask is far superior to any other mask on the market. Period!”

Debbie, the mother of Kayla, knew that she needed proper respiratory protection if she wanted to play with other children. She had her tried all sorts of masks, Surgical Masks, N95 Masks, but none of them worked. Due to her weakened immune system after the Chemotherapy, Kayla would fall sick easily after she mingled around with other kids. Determined, Debbie continued to search for a solution. One day, a Google search led her to Totobobo mask. After studying the website, she decided to give it a shot. To her surprise, the Totobobo mask worked!

Testing 9 types of air filters with a laser particle counter

The filter is the most important component of a respirator. The quality of air that gets into your lung is determined by the quality of the filter, provided there is a good seal between the mask and your face.

The design of Totobobo mask makes it quite easy to replace the filter with any flat, air permeable material. It is tempting to use a filter look-a-like such as cotton wool or a piece of felt to replace the used filters. Does it work? I am interested to find out how effective these different alternatives are.

A Dylos laser particle counter is used to collect objective data. The particle counter is affordable and performs consistently. I’m using the Pro version which is able to detect two fine particle sizes: 0.5 and 2.5 microns. The particle counter has an air-inlet and a exhaust vent. Air drawn into the counter goes through a passage and there is a laser diode and an optical counter along the air passage. If the air inlet is covered by a piece of filter, air drawn into the unit will be filtered and therefore produce a lower particle count reading. The performance of the filter can be calculated by dividing the ambient particle count value with the “filtered” value. For example, if the particle count drops to half, the protection factor of that particular filter is 2.

Laser Particle Counter
Dylos Laser Particle Counter

The method is simple and easy to understand. First of all the ambient particle counts is measured against two different particle sizes 0.5 microns and 2.5 microns. Different types of filters are used to cover the air inlet (edge seal with tapes) one after another. Reading of each filter is obtained after 2 minutes when the value stabilized. Finally, the ambient particle count is once again measured without any filters. The first reading without the filter and the last reading are within 5% tolerance.

Laser Particle Counter reading without filter
Laser Particle Counter reading without filter

Protection factor (P) of each filter is calculated by the formula:

P = Qi / Qn

Where Qi is the value of ambient particle count without filters and Qn is the particle count of the filter concerned. Higher P value indicates better protection factor.

The Totobobo filter (low cost anti-pollution filter) produces a high protection factor of 5564/587 = 9.5 (for 0.5 microns) and 184/10 = 18.4 (for 2.5 microns). This figure indicates a high filtration efficiency of over 90%, effectively raise air quality from “VERY POOR” to “FAIR”.

Surgical mask is commonly used, the problem is getting a good seal. In this test, we seal the surgical mask filter media over the inlet to measure the filter effectiveness. As expected the protection value is not very high: P=2.9 for 0.5 microns, P=4.8 for 2.5 microns.

As a reference, the filter of a Respro City mask is also tested. The result is disappointingly poor: P=2.2 for 0.5 microns, P=3.1 for 2.5 microns. I am shocked since this product was reported some years ago to be among the “top performers”. I checked several times to make sure the readings are correct. It may be possible that my sample is dated (over a year old). I will update this record if new evident is found to prove this results wrong.

Magiclean is cheap and commonly available and it’s working principle is based on static charge in the fibre, a characteristic of Totobobo filter. I expect it shell produce reasonable good performance. However, the result of 4 layers of Magiclean wiper is the worst out of the lot: P= 1.6 for 0.5 microns, P=2.2 for 2.5 microns.

Facial pad is probably the most commonly used “replacement filter” since some of them available in similar dimension as Totobobo filter. The result of the test is: P=2.4 for 0.5 micron, P=3.5 for 2.5 micron. This is slightly better than the result from the Respro filter.

Finally a benchmark test was performed against the well know 3M 8210 N95 filter. However, as the air resistance is too high, we need to enlarge the total surface area and we manage to seal the enlarged area around the inlet. The performance of this filter is remarkable: P=12.8 for 0.5 micron, P=33 for 2.5 micron, highest of the lot. The only problem with this material is the air flow resistant. It is more difficult to breathe through.

Note: these tests are intended to compare relative protection factors between different filters. These test results are not calibrated to various manufacturer’s standard or NIOSH.

Conclusion:

3M 8210 N95 and Totobobo are the only two filters provide real protection factor above 9.5. These results is consistent with the finding of a study done in the Chinese University of Hong Kong (Prince of Wales Hospital). However, the air resistance of the 3M 8210 filter is too high and is not suitable to be used with Totobobo mask.
All other alternative filters are considerably less protective.

Update:
I managed to get my hands on a new Respro Techno Gold filter and tested it with the laser particle counter. The result is much more promising than the Sport filter. In addition, I also tested the Totobobo 94% and 96% filter to complete the picture. The 94% is the 2nd best performer for 0.5 micron and slightly less protective than the 3M 8210 filter for 2.5 microns. The Totobobo 96% is the best filter so far. Added a chart for easy comparison.

How does a mask protect you from haze?

Haze in Singapore
Haze in Singapore

The haze is back in Singapore, fuelled by raging fires in Sumatra. Thursday’s PSI was the highest recorded here in almost two years. Experts here said on Thursday the haze might linger over Singapore for a while, due to the prevailing south-west monsoon season conditions, which typically last till late October. If the situation worsen, put on a mask when you go out may be a good way to protect yourselves. Do take note if you do use a mask:

If a mask can not seal your face, it can not protect you from the haze.

Haze is an atmospheric phenomenon when airborn particles such as dust, smoke and other particles obscure the clarity of the sky. The haze particle are very fine and easily get breathe into your lung by following the air flow.

Buoyant haze particle follow the “passage of least resistance”. The working principle of a mask is to seal off the breathing zone such that the least resistant path through the mask is the filter. Air must go through the filters before it can reach the breathing zone. The particle is trapped on the filters and therefore the air is cleaned before entering your mouth or nose.

Regular surgical mask or even N95 mask won’t help if there is gaps between the mask and your face. A gap between the face and the mask is an alternative passage with less resistance than the filter. Air and the particle will leak through the gap rather than going through the filter. One of the key concern when using a regular mask is how can one decide if the mask is truly fitting and sealing the breathing zone?

Here in Totobobo mask we provide the possibility for you to check the fit through the transparent mask. You can adjust the position, the tension of the strap, or even cut the mask to make it better fit to your face. Although we can not guarantee it will fit everyone, yet the chances of fitting is much higher than a regular mask.

In addition, judging by the colour change you will be able to tell when the filter has done it’s job and should be replaced.

For demonstration, here is a pair of filter kindly provided by Kenneth Koh of Advanturenomad. He use the Totobobo mask during his cycling trip in Vietnam. The colour collected on the mask is the result of nearly 30 hours of cycling in Vietnam from Hanoi to Dalat.

Totobobo mask for air traveller

Recently we travel to Taiwan and Hong Kong. To be on the safe side we all put on our Totobobo mask on the plane and in the airport. Who knows the one sitting next to you can be coming from a H1N1 flu infected country? This was the “acid test” to see if the mask really work in the context of air travel.

I’ve customized the masks for the two boys and Sharon in advance. So that part is not an issue. Putting it on was easy for Sharon and the younger boy, but it was confusing for the elder one. It turn out that the strap of his mask got entangled a bit and he couldn’t slide the strap along easily. I help him to remove the rubber band and disentangle the strap. He mange to put it on afterward.

A point to note about customization, it is not always true that smaller face need smaller mask. If it fit and seal well, a larger Totobobo mask is usually more comfortable to wear. So if you find the mask too big, start by trimming it a step, never jump to the smallest size immediately. You may find an intermediate size that seal very well and is comfortable to wear even for a long time.

Wearing the mask for an hour or so is not uncomfortable. In fact we pretty much forgot about it because it didn’t interfere with what we do. We all wear glasses, sometimes we read magazine, sometimes we watch TV and sometimes I was busy taking photos 😉

using Totobobo mask for air travel

We had to remove our masks when the food came. We just remove the top strap, pull the mask down such that the contracted top strap now keeps the mask closed, and we just let the mask hang around our neck while eating. We put the mask back after the meal. The elder son fall asleep and the younger one kept watching TV.

I noticed many passenger used surgical masks. One family of three used N95 cup-shaped mask. But the huge N95 mask was not fitting the child and clearly he was not getting much more protection than those wearing surgical mask.

air-steward ask about totobobo mask

Some curious passenger ask where we got the mask from and even the stewards are interested in it. The surgical mask they wear is not giving them the protection they really need. It’s a pity that they have to face so many people from all over the world during the trip but not getting the protection they deserved. Anyone with friends working as air steward? Perhaps you should let them know about Totobobo.

Leaving the plane, we took off our mask when we were shopping in the airport shops, there seems to be more space between people and none of the staff or customers looked sick. Keeping it hanging around the neck was most appropriate because we needed to put on the mask again when we go through the next risk spot- the crowded custom.

Put on a brave face

The Totobobo is the world’s first customisable respiratory mask.

The swine flu that’s sweeping North America and Europe might have you rifling through your cupboards for the face masks you bought six years ago. While most of us simply chucked them into some cabinet or drawer after the Sars outbreak, one man was motivated by the fact that A: The N95 plastic masks are uncomfortable, and B: children could only wear surgical masks and these didn’t filter out airborne viruses.

BREATHE EASY

Totobobo is made with a special blended plastic which is soft enough to comply comfortably to the contours of the face, but not too soft that it touches the mouth.

Product designer Francis Chu put on his thinking cap, after encountering these problems in 2003. ‘As a father of two young children, I was really concerned about this. The challenge that presented itself was clear – to come up with a mask that would fit not just adults but children, and at the same time feel comfortable,’ he explains.

Being a product designer, he was therefore sensitive to user issues and ergonomic requirements. ‘Although I don’t have medical training, I have been involved in designing for disabled children,’ he says. ‘I studied the principle for respiratory protection in different fields, including the medical. I also asked advice from my friends working in the hospitals,’ he adds.

To fund this project, Mr Chu sold his car, trading it in for a bicycle for transport. He started creating hundreds of prototypes using paper first, to find a shape that would best fit various face sizes.

It took six months before he came up with a final design, and he filed an initial patent for it in 2004. That was the genesis of Totobobo (Mandarin for transparent (toto) and protection (bobo)). From then on, it was a matter of getting it to the market, which Mr Chu did – and in no better time as well – earlier this year.

Having a snug fit is important because if it doesn’t fit, you’re not fully protected from contaminated air.

Totobobo is now the world’s first customisable respiratory mask, designed to fit all face shapes, which is also child-friendly.

Having a snug fit is important, he stresses, because if it doesn’t fit, it means you’re not fully protected from contaminated air. This defeats the purpose of wearing a mask, he points out.

‘Current respirator solutions require fit-tests to ensure that the mask fits the individual’s face, which isn’t a realistic requirement for most people,’ explains Mr Chu. In terms of fit, Totobobo is made with a special blended plastic which is soft enough to comply comfortably to the contours of the face, but not too soft that it touches the mouth. The mask doesn’t contain silicon or latex, but can be washable.

On both sides are filtering material imported from Germany, which is able to block 94 per cent of very fine particles including bacteria and germs. ‘If a higher level of protection is needed, you can put two layers of filters together and that will bring the filtration efficiency up to 99 per cent, comparable to N99 masks,’ says Mr Chu.

The good thing is that putting on the mask won’t make you look like a SWAT team member. ‘My intention was to design a mask for normal people and I wanted to create something that would not look too odd when worn in public places, such as a crowded bus during the flu season,’ he explains.

The current swine flu scare is certainly going to see sales of Totobobo go up, but even before this scare, Singapore-based Dream Lab One (the company that Hong Kong-born Mr Chu and his wife, Sharon Li, started) had been selling the mask online, and it has been bought by consumers from over 20 countries.

Among the target audience are cyclists and asthma sufferers, as well as travellers who need to block out both polluted air and other various irritants.

If you’re checking through your mask supplies, it’s time to get up to date with a Totobobo mask. Most likely, the surgical masks from the 2003 Sars days would be unusable, as the straps would have disintegrated into pieces. I should know since I unearthed mine this week.

– Debbie Witte, Kaylas mum @ www.freehelpforcancer.com

Debbie known that her daughter Kayla needed proper respiratory protection if she wanted to play with other children. Kayla tried all sorts of masks: surgical masks, N95 masks but none of these work. Due to her compromised immune system after the Chemo-therapy, Keyla fall sick easily time after she play with other kids. Undefeated, Debbie continued to search. One day, a Google search led her to the Totobobo mask. After studied the website, she decided to give it a go. Much to her delight, the Totobobo masks works!

Filter + Face seal = good protection
The principle of how Totobobo mask work is simple: Isolation (good seal) and filtering.

principle of respiratory mask protection

Good protection = good seal + good filter

“Good protection is built on two factors: a good filter and a good seal“.

Surgical mask is not good enough

You may have seen news on TV that many school kids in Asia wearing surgical masks during the SARS. But the fact is surgical mask was not designed to prevent air-borne contamination. There are gaps from both sides that virus can bypass the mask easily.

sugical mask showing gaps from both sides

Surgical mask is designed to protect nurses or surgeons from contaminated blood splash during an operation. In Japan it is commonly used to reduce the risk of spreading the flu virus from the wearers when they are sick. The protection value of surgical mask from air borne virus is a big question mark.

N95 mask effectiveness: fit-testing is a problem

Adult N95 mask big gaps on child's face

Respirator (e.g. N95 mask), on the other hand, is designed to protect the wearer from air borne virus. This is only possible if the respirator is making a good seal on your face such that air have to go through the filter before entering the breathing zone. However a proper fit-test can only be conducted by a trained specialist with special equipment, which is simply too complicated for the public.

Manufacturer come up with “user seal check” which typically involve blocking the filter and blow into the mask while wearing it. To feel that if there is any air leak from gaps around the mask. But such practice is questioned by a study from the Prince of Wales Hospital in Hong Kong. The study suggested there is 25% of failure rate when trained users apply the standard “User seal check”. The standard user seal check recommended by most manufacturers is just too ambiguous and unreliable. “It’s usefulness as a pre-use test must be questioned”, the report concluded.

Another study Respiratory Donning in Post-Hurricane New Orleans (US CDC, May 2007) found 76% participants were not able to demonstrate proper donning for a good seal and their protection has been compromised.

When looking for a respirator to protect his kids, Francis Chu, the inventor of TOTOBOBO mask, encountered the same frustration as Debbie. He became aware of the many difficulties faced by parents and determined to come up with a better solution. He applied his expertise in product design and experimented with hundreds of prototypes. Finally he came up with an ergonomic design that fits most people and can be customized to fit children.
He understand that beyond a good seal and good filter, other issues like comfort, cleaning, reuse, portability are all important factors need to be addressed before the mask can be considered as “Child Friendly”.

Following is a summary of the issues and respective solutions embedded in Totobobo:

PROBLEMS…………………………….. SOLUTIONS

Children’s face size varies ……... Trim it to fit small faces

Hard to determine a good seal …… VSC Visual Seal Check makes it easy

Difficult to disinfect (for reuse) …… Anti-virus mask easy to clean and safer to reuse

Children’s skin is delicate………… FDA approved, non allergic soft material

Not easy to carry………………..……. light weight, folded flat

Parents and school teachers from different parts of the world have discovered the new solution for their children. If you are looking for an effective mask to protect your child, TOTOBOBO is exactly what your are looking for!
