Smog the Dog is confused… Toto what??? Toto my butt. Looking at the two references below, Smog the Dog couldn’t believe what he was seeing…
Did some one shout ‘set up’ or ‘fix’ or some other phrase used to highlight a fake review or did Claire (pictured promoting Totobobo mask on the Totobobo home page) get a no expense spared trip from London to go all the way to the back waters (with her partner) of a far eastern country (Far eastern back drop picture promoting Totobobo mask on the Totobobo home page) to do a review for London Cyclist blog, supposedly in London. I don’t think so.
Either London Cyclist blog (not to be confused with the London Cycling Campaign or their magazine The London Cyclist) takes incentives or takes the public for stupid. Why put a cropped picture on the LC review taken from the homepage of the supplier of the product she is supposedly reviewing. Crass thinking man!
Well, the public aren’t stupid and what little credibility such a mask configuration has, vanishes into the polluted ether.
The Totobobo mask adheres to one out of four of the basic principles that a mask or in technical speak, a ‘filtering face piece’ should adhere to.
1. The mask should be ‘orinasal’ (covers nose and mouth)
It is a given, that we breathe though our nose and our mouth. The mask should cover both breathing orifices otherwise you have to make a conscious effort to breathe with the right technique. This is pain to do and takes concentration otherwise , “oops I forgot to breath through my mouth” “oh well, the pollution really isn’t that bad”
Breathing is a reflex processes that we do not think about and should remain that way. In through the nose, out through the nose, in through the mouth, out through the mouth,….. it should remain a thoughtless process.
Totobobo Super cool mask is so cool, it lets you breathe through your nose if you want, how cool is that! …cough cough!
2. The mask should have a nose clip.
Masks used in industry have a nose clip of some fashion whether it be a strip of annealed aluminum to bend to an individual users features or something like a spring clasp. This vital component is required in order to seal between the bridge of the nose. This is the most common place for air leakage and without a nose clip you are rendering your mask next to the useless category. This will mean that unfiltered air will pass straight into your lungs by-passing the filter.
In order to create an effective seal the mask needs a nose clip. Totobobo mask….. oooh,… doesn’t have one!
3. The mask should have at least one exhalation valve.
Heat, water vapour and Carbon Dioxide are plentiful when exhaling and the last thing you want is either to breathe them back in on your next breath or the water vapour to start saturating the filter material as it passes out of the mask; it has to go somewhere! The resultant is the ‘wet flannel effect’ which is where you cannot breathe for all the water in the filter material or all the tea in China.
Without valves you also get condensation build up. The only way to avoid this other than by having valves, is if there are large gaps around the sealing area allowing the exhaled air to pass out. Air travels through the path of least resistance, so if the air passes out through the gaps then it will also pass in through the gaps, meaning that the air passing into your lungs is guess what…unfiltered. Surprise!
4. The filter media should have the largest possible surface area.
The key to low inhalation resistance is the amount of surface area the filter is providing for air to pass through, for example try breathing through a biro pen tube and see how much air you an get into your lungs and then try breathing through an empty bog roll. The difference is obvious. Like the filter disk in the Totobobo mask you will have difficulty drawing a couple of litres of air through the filter in one breath which is the average volume of air taken in each breath. Now multiply this by 20 and you will get 40 litres of air trying to pass through the filter every minute…. and back again because there is no exhalation valve. Exhausting work if you ask me!
Sounds like the scientists at Totobobo school of masks didn’t pass their exams.
Well, simply explained and as far as I am concerned, it is a mask that will pass into history as one of the many masks that have been put on the market by companies who try to cash in on the back of a serious global problem. The global pollution problem is not going away unlike the Totobobo mask which most definitely will.
