Fredoops beat me to the physics correction
been dealing with alot of people like this lately - not afraid to run off their mouth but then have no idea about the mechanics behind anything
makes me wonder about the schools they have been attending - i would be asking for a refund

physics aside, i am a mechanical engineer and on product design basis the fujita still has my vote

and i fail to see how the filter irrelevant? its one of (if not the only) most important parts of the kit -.-
