Whilst I applaud the efforts made by some of these companies and the efforts made by the BMC to publicise these efforts we must be careful not to induce a false sense of security by promoting untested and uncertified personal protection products (PPE). I note that Decathlon clearly note that their mask system is not certified and should be praised for this honesty. Personally I would not rely on PPE that is not fully tested to FFP2 or FFP3 standards and for the higher level of protection offered by FFP3 for riskier exposure it would have to be personally fit tested. The Osprey and Organic Climbing products give me no confidence whatsoever. The virustatic "buff" worries me even more since their website states it is based on science but gives no references and is very vague. It lists a lot of popular news sources under their "what people say" section on their website but nowhere does it quote studies by a reputable medical source published in a reputable peer reviewed scientific journal or any form of certification. We must be very careful not to promote products which give a false sense of security. They lead to more risk than having no sense of security at all. Think carefully about spending your money on uncertified and untested products. These are my personal views an not those of the BMC. I have no conflicts of interest.
