If there’s air outside, I ride. I adjust my expectations for speed and distance based upon conditions.

Agree. I’d rather have lung damage than live my life based on a weather report.

On bad ozone days, I’m switching over to bus/metrorail, so it’s not clear how you extrapolate this to “live my life based on a weather report”. I personally would prefer not to damage my lungs by ignoring such conditions, but that’s just me. I bike commute for improved health and reducing dependence on foreign oil, and continue to meet those objectives with this approach.

I’m just speaking for myself. You don’t need my permission or approval to make your own decisions.

The damage done to me by not riding isn’t always visible. I feel it though. I guess that answers the “Why do you still ride after being hit by cars so many times?” question too.

I thought about going out today. But then the wife woke up late and I was stuck babysitting. I think deep down I was looking for an excuse. When I go out to ride I generally go for a workout and get ready for my longer ride late August. I’m just worried I’m doing more harm them good once I’m huffing and puffing.

No problem, I didn’t ask. I admire your tenacity at bike commuting, though.

Good point. I am shooting for at least 5 hours per week on two wheels, though am typically over 7. No doubt others are higher.

No need to worry what others do. Awesome that you’re getting the time in the saddle. I think most of us wish we could ride more than we do. Great job!

With that being said. I went to Indian Head Rail Trail this morning, away from the city. Breathing was great! I could breathe in deep, smell more the pavement and there was even a cool breeze.

Yeah today is yellow, which isn’t that bad but peaks around when I do my home commute. Bleh.

I usually keep a browser tab open on weather.gov’s forecast ozone levels for my location, and refresh the page before heading out. Here’s Rosslyn, VA:

An easier to read handy one is:

although it’s only a 2 day forecast, I think – the third day is always gray.

I wear a Respro Techno mask on orange days, for as long as I can. It is hard to get enough oxygen with this on. (link: http://www.respro.com/products/industrial/urban-environment/techno_mask/ )
This mask is supposed to filter out both particulate matter and gases/vapors such as ozone.

They’re a UK company which seems reputable to me (they were carried in many stores in UK) but do have some limited distribution over here.

On orange days I also drive most of my commute and just ride 3.5 mi (each way).

Red days I probably wouldn’t ride…

Here’s some other pollution masks I’ve considered too.

I would consider trying this one, it closely resembles the Respro but don’t know how good it really is:
http://thefilt-rmask.com/

Another couple of similar options, websites are a bit basic though
http://www.gflowmask.com/
http://icanbreathe.com/store/page15.html

Don’t know anything about this one, it looks unwieldy, and there’s not much info on the site about what it actually filters out:

Love the design of this one, but it doesn’t filter ozone or CO afaik:

Thanks for sharing this. When I went to the site and drilled down for more detail, it seems to focus on particulate matter down to 0.3 microns, which is far below the level of the 2.5 micron standard, so the PM protection looks outstanding.

I didn’t see anything about ozone control, did I miss something?

Thanks again for running down a number of masks, btw.

No problem. I researched a bit myself due to concerns about commuting pollution. I added a couple more options to the list.

Sorry, I missed a bit in my original post. Should’ve said “both particulate matter and gases/vapors”.

Anyway, here is a bit about gases/vapors that mentions the “Dynamic ACC (Activated Charcoal Cloth) filter” that’s in that mask’s filter.

There’s all sorts of things in urban air. Professionally I work with historic architecture and old buildings. Went to a seminar on historic masonry. When they clean masonry buildings of decades worth of grime, guess what the number one contaminant is. Rubber. Rubber from millions of tires slowly wearing away, every day.
