Ok, i'm chill...
for the sake of this discussion...
what is the function of the engine air filter in your car? to keep bigger particles of dust from interfering with the combustion process, right?
how big do the particles have to be before they affect the combustion process? can't be as small as 2.5 microns - the combustion process itself produces carbon particles. this is what you see at the end of your exhaust, more commonly known as soot.
so what is the size of the carbon particles? pretty big, since it can be seen with the naked eye. but for the sake of discussion, let's say they are much smaller.
what is the point of filtering out the haze particles if the engine is producing soot which is much bigger?
another point to note - the amount of air that can pass through a filter is inversely proportionate to its efficacy. this means that the finer the filter, the less amount of air passing through.
the stoichiometric ratio (go google it) is 14.7:1
good luck with installing N95 filters to your car. get ready to see a lot of smoke - your car will be running extremely rich due to oxygen starvation.
you familiar with the saying "using cow knife to kill ant?" - end up killing your car.
what would make better sense is to install N95 filters to the exhaust - to prevent more pollution. but then again that will cause restriction of exhaust, which is another story altogether...
