From London, UK

Hi,

For the record I bought a totobobo mask about 4 months back (the one that covers mouth only). Delivery was quick and I bought about 60 odd of the 92% filters. It has made a MASSIVE difference to my commute - before I used to have a very sore throat by the end of the week. Even when I'm not cycling in London (and I don't have the mask on) I notice a clear difference.

I would say a very good investment (surprisingly hard wearing given that it looks quite flimsy when it arrives). The filters go black in just over a week for me and it is quite shocking how much dirt they seem to pick up.

I cycle fast and I would say it was initially difficult to get the breathing right but its good and the fact that it doesn't cover your nose means that your glasses won't fog up. If you feel silly wearing it just get one of those neck bandana things (in Evans for about 13 quid) they cover the whole mask (without slipping down) and dry quickly and easily.
