Started watching this last night...pretty interesting.

im planning on watching the whole series.

...okay so if you want to see filters section only...scan to about 30 mins into the video...

i was always thinking they were a marketing gimmick..

Note before you watch this..its called tobacco wars and is a documentary about the tobacco industry...so if you dont want to see some of the content ..just fforward to 30 mins in...the filter section on the brief gov filter testing results blurb is about 3-5 mins...
