Jean-Francois Monin riding with totobobo mask in Beijing

Jean-Francois Monin lives in Beijing who  bikes a lot and has been using a Totobobo mask since 2010. After one year, the strap was broken too many times and he needs to order replacement. “My earloop is broken in at least 4 places — I should have ordered earlier in fact. It seems that the duration of an earloop is roughly a year.” Said Jean-Francois. He used a Classic Totobobo at the beginning and afterwards changed to Earloop version because he found that it fits better. We took the opportunity to interview him about his experience of using Totobobo mask for cycling in Beijing. Here is the full interview:

————————————————
1) Why do you like to cycle in Beijing?
I like to cycle in Beijing because it is the most eco-friendly and most predictable transportation mode. It is the fastest for short distances (< 4km)

Compared to other mode of transportation, bicycle is as fast as the subway and cars, and faster than bus on longer distances (up to 15 – 20 km).
By experience, I was often faster than people using other transportation means. I think that electric bikes (very common in Beijing) are faster, but they are a bit more expensive; and then you are more incline to use roads with heavy traffic where air pollution is worst.

The problems of other transportation modes are the following:
- Buses suffer from waiting time and depend on traffic.
- Subway is not very frequent and waiting time can be very long in some situations.
- Cars? parking issues and traffic is unpredictable, and sensibly more expensive.
- Taxis? You may have to wait, and traffic is unpredictable.

However cycling has a couple of drawbacks: namely road danger and air pollution. You need to understand the local traffic culture, which is very different from France for instance. To cut down the pollution I use a Totobobo mask.

2) Is there any reason that makes you feel needing a pollution mask?
Before (having a mask): I discussed with friends and became aware of pollution issues.
Now (having used a mask for 1 year): the change of color makes it clear that it is actually useful!

3) Have you tried other mask before?
No

4) What do you like about the Totobobo mask?
Efficient, light, easy to wash and change filters.

5) How often do you use the mask?
Every day, at least twice, often 4 times

6) Where would you like to see improvement of Totobobo mask?
Sometimes I have to remove the mask from nose and mouth for a few minutes, I’d like to do it conveniently, without stopping (I often use my 2 hands in this operation or the converse one — installing the mask on my face again, hence have to cycle without hands, which may a little bit dangerous).
Another suggestion is for the Totobobo website: it says very few about matrix filters. I tried to find independent information about zeolite and decided to test matrix. More precise explanations and evidence about the efficiency of this product would really be welcome on your website.

7) Will you recommend Totobobo mask to others?
Yes

Air pollution in Beijing

by info on February 24, 2011

Smog in Beijing

A surge of orders from Beijing over the last couple of days caught our attention. According to the customers, some from different Embassies there, the air quality in Beijing is the worst they have seen at this moment.

The Independent from UK posted “Index of air quality in the world’s major cities” which compiled data from AirNow, CITEAIR, and the American Embassy in Beijing. It confirmed that the Beijing air is the worst at the moment compared to cities like Hong Kong, Shanghai and New Delhi.

Particulate pollution, rising temperatures and a lack of wind caused the stifling smog, which reduced visibility in parts of the city to just 200 metres (yards), the Beijing weather bureau said in a report.

The American embassy in Beijing rated it as “Hazardous” on the 21st of February. Traveler going to Beijing is strongly advised to carry a good mask (seal your face).
Hopefully the situation will be improved when the wind starts to blow later this week.

Pollution Masks: Which Are Best?

Real World Testing

I tried it around town for a bit, and the overall comfort is good. It definitely is less awkward-looking than the typical N95 with exhalation valves. I was pleasantly surprised with the seal and that my glasses didn’t fog up, although I got those mask lines on my face that other masks also cause. It’s relatively easy to keep on, with straps either behind the ear or behind the head (which always provides a closer fit).

I didn’t do any fancy technical testing with it, but on a bad, smelly day I put on the mask and instantly could no longer smell that pollution.

Also, there are a few other real-world advantages:

It’s not totally uncool-looking
It’s reusable and washable, and it’s easy to carry in a pouch (provided by them)
There are kids sizes
You can quickly cut the mask to fit better
The masks and filter refills are very reasonably priced

My Bottom Line

Totobobo didn’t pay me anything, and I get no income from them for this mention. I’m simply trying to find well-researched options to protect myself and anyone else from Beijing’s air pollution, and I’d be more than happy to review other masks as well and to publish the results. Last year I tried to find good studies on other brands, including Respro, but I found no well-designed studies on other masks. Does anyone have such information?

I think Totobobo is a good and affordable option for people. And a 135-fold drop in pollution is very impressive; even on an emergency day with the AQI over 500, the mask would bring your air to WHO-safe levels.

A research published on 13-3-2009 in the Particle and Fibre Toxicology indicates that wearing a respirator may reduce the risk of heart attack.

“This simple intervention has the potential to protect susceptible individuals and prevent cardiovascular events in cities with high concentrations of ambient air pollution.” stated in the website.

The research was led by Dr. Jeremy Lingguish of the Centre for Cardiovascular Sciences, Edinburgh University. The team consist of experts from Centre for Environmental Health (The Netherlands), Institute of Occupational Medicine (UK) and Fuwai Hospital in Beijing,  China. 

The randomised controlled study involves 15 volunteer walked on a predefined city route in Baijing. The subject exposed to ambient air pollution and exercise was assessed continuously using portable real-time monitors and global positional system tracking respectively. Cardiovascular effects were assessed by continuous 12-lead electrocardiographic and ambulatory blood pressure monitoring.

The mask-wearing group result might have been affected due to poor mask-to-face fit. Despite this, the mask wearing group demonstrated least affected by exposure to the air pollution.

Exposure to fine particulate air pollution is known to associated with increased cardiovascular morbidity, but it is not clear how this happen.

In another experiment, Magnus Lundbäck  et al developed a simple non-invasive method of assessing arterial stiffness and apply the method to demonstrate exposure to unnoticable among of diesel exhasut can indeed increase arterial stiffness. This is possibly the best way to explain the link between air pollution and heart attack.

The team from Sweden and UK discovered that men exposed to small, unnoticable concentration of diesel exhaust (350 ug/m3) increased the augmentation pressure by 3 mmHg and augmentation index by 8 %- indicating an increase in arterial stiffness. In a patient with established hypertension or coronary artery disease, small changes in central aortic pressure may be sufficient to trigger an acute cardiovascular event (e.g. heart attack, or stroke)

A point to note is PM concentrations can regularly reach levels of 300 ug/m3 and above in heavy traffic, occupational settings, and in the world’s largest cities.

Beijing: dirty on the outside, clean on the inside?

June 22, 2008

10 June 2008 Hervé Bonnaveira Crossing a megalopolis by bike gives you a good idea of how polluted it is. Arriving in the Chinese capital from the South we followed a long line of thermal power stations and factory chimneys, which turned our totobobo anti-pollution filters black after 6 hours of use. Arriving in the [...]
