Polution Masks

[0omo0]

can anyone recommend a pollution mask that is good and that allows you to breath properly?
I have purchased 3 so far, 1 cheep one from ebay and 2 from amazon. I find they are either useless with glasses or i cant breath in them sufficiently when i am cycling. any recommendations gratefully received.

Air is polluted enough without having a polution mask.

I found the two filtration points on this cheap mask to provide sufficient flow. Which ones have you tried?

Looks real polluted where he,s tryng it...???

I tried this one https://www.amazon.co.uk/dp/B00HF3AVIG/ref=cm_sw_r_cp_apa_tqpdzbP2NGTY0 air flow was good but it's uncomfortable and no good with glasses.

This one is comfortable but only has one filter and doesn't let you breath enough to cycle

@Zlatan At times it's polluted with bugs, midges and other summer critters.
Pollution takes many forms.

@0omo0 I probably don't push myself enough to feel any breathing restrictions in that mask. It's a Godsend when the bugs come out in the evening though.

It was a really cold evening when that video was done. Starting at around 6 seconds you can see my frozen breath. That'll give you an idea on airflow restrictions with the particular mask, compared to the ones you had.

I cycle into central London every day for work which is why I'm asking. As during rush hour the traffic sinks. I wouldn't be asking if i was in the country side

In that case, I wouldn't really know much. Googling came up with some positive reviews on this mask. It's quite expensive though. Good luck in finding something suitable.

Thankyou i will give that a try it sounds good

Worth a try. But maybe it'll still be stuffy. I found this reviewers comment of interest;-

All the above are passive masks and the uzers still need to exert lung pressure to overcome the filtration resistance to air flow. You should try this : http://www.ecbreathe.com which is an active powered adaptor for N95 masks. It uses battery power to overcome the filtration and the user would not feel any discomfort/stuffiness with the use of the mask. It supplies up to 700 litres of flitered air per hour.

I'm afraid the Respros are all P1 so no good for diesel particulates. P2 is the minimum for diesel.

I'd be nervous about that as it doesn't seem to have an FFP rating on the website I can find.

The only one I can recommend is a 3m 9322 (or other 3M FFP2 aka P2 disposable with identical design - there may be one). I get them for about £1.50 on eBay; they've got excellent fit - which as LeighPing rightly implies is important; they've got good flow; and they're FFP2 rated which means they *allegedly* catch a lot of diesel particulates - FFP3 will catch more (I've got a feeling FFP2 won't cover the <2.5micron (micron?) super-small particulates, poss the intermediate 5 micron too) but FFP3 won't be as breathable.

Sadly there's a message here: adequate protection means no cycling because of too-little flow. Ergo don't do stuff in traffic which makes you breathe heavily. I don't know what side-streets are like in terms of particulates etc.

 

[jonathan75]

Oddly enough a scientific study found that filtration was worse if you have bad 'fit', i.e. having a beard/stubble would tend to be highly significant for filtration (as well as of course bad fit design, and too low a protection factor of filter).

I'm glad that I've only got bugs to contend with. Pollution is just too complicated.
