Cyclists, move away!

by info on April 21, 2011

That’s the conclusion I got when looking at the animated 3D ‘Pollution map’ video of London. The orange yellow color, mainly along the main roads, indicates high level of air pollution where the blue color are area with better air quality. It is intuitive to think air pollution level is higher along the main roads and lower away from the main roads, but I could never imagine the differences can be so huge!

In the short video below you can see the highest air pollution concentrated right along the main roads and junctions, likely the result of slow moving vehicles there. Most of the area away from the main roads are much better.

If you are waiting for the green light at any of such junctions, hold your breathe. Because the ultra fine particles (0.1-0.3 micros, currently not being regulated) can travel deep down into the lungs and stay longer there than their bigger brothers (>2.5 microns). Ultra fine particles significantly reduces the positive effects of good cholestary
There are increased evidents showing these ultra-fine particles are the silence killer closely links to respiratory and cardiovascular diseases.

Cyclist! Wear an effective mask, or move away from the busy roads!

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.

Give cyclist a Safety Wing

by info on August 14, 2010

Riding in Seoul with a safety cyclist wing

Riding in Seoul with a safety cyclist wing

A conceptual work as mentioned by UrbanVelo.
Cyclist safety is one of the main concern that stop potential cyclist to choose bicycle as a mode of transportation.
Many drivers, even some cyclist, believe cyclist enjoy the road at the expenses of road tax paying car-owners.
The “Cyclist Wing” enhance cyclist visibility and safety on the road. From the driver’s perspective, the “Wing” makes cyclist becomes 300% more visible, and therefore easier to avoid.
“Safety by number” is an important factor supported by a huge body of research finding. More cyclist = more safety for cyclist .
The “Wing” makes the visual population of cyclist in any city increased to 300% with the same number of cyclists. Driver need to drive more carefully due to the apparent increase number of cyclists on the road.

With the air-cleaning function of the “Wing”, cyclists make a tangible contribution to the environment, at the same time return the right-of-way to cyclist.
it is also a subtle reminder of the harmful pollution from cars. The “Wing” earn the right-of-way for cyclist from a social perspective.

The “Wing” will help to tilt the favor towards cyclists and turn more potential cyclist into real cyclist.

Do you think the air-cleaning-cyclist-wing concept can work in your city?

The coolest pollution mask

The coolest pollution mask


Ross X, the "dude-on-a-bike"


————————————————–
The SuperCool mask is great–hands down. I don’t work for Totobobo–nor am I paid to say this, and I’ve been using this mask for a few months now. I first started with the original one that covered the nose and mouth. I liked the simplicity and that I could easily wash the mask–but as a glasses-wearing cyclist, my glasses seemed to fog up when stopped at red lights or slowed down (at higher speeds the breath exhaust seemed to present less of a glasses-fogging problem). This was a problem.

But when I wrote to the company informing of my problem they were willing to offer a few suggestions. One was to try cutting the mask to better fit my head, but the other was about this new version that only covers your mouth. I gave it a try.

That I am no longer exhaling into the mask, the fogging glasses issue has completely disappeared. (I breathe in through my mouth, which is in the mask/filter, and out through my nose.) Actually, I think I get a better seal with this smaller mask than I did the full one. And I find there is much less condensation collecting in the mask (no humid exhale within the mask), which means I do not need to wash the mask as often. This may also have a positive impact on the filters (keeping them drier), but I’m not a scientist, so I can’t credibly comment on that.

Pulling down the mask to talk to other cyclists is also very easy with this mask. You can talk through the mask, but you might sound a little like Darth Vader, so I simply pull the mask down around my chin if I want to talk, then pull it back up when I ride on. The side straps are very stretchy.

I also have a mask by another company–it’s neoprene and velcros in the back. I haven’t really tried this mask extensively due to a few reasons: 1. it looks like it would tend to get hot in the summer days here in Los Angeles–as it covers a lot of skin on your face and neck essentially with a wetsuit, 2. the metal nose bracket, which I thought would be beneficial to get a good seal, seemed to irritate my nose, and 3. the Totobobo is just so light and easy to use I just haven’t had a compelling urge to try another mask.

Big props to the company–who has seemed to design a great, simple product–and whose customer service has been very responsive and helpful. When I change out the filters they are visibly discolored–and I’m glad that at least some of that stuff that I otherwise would be breathing (dirt, pollution, particulate matter, brake shoe dust, etc.) is in the filter instead of in my lungs.
