[TR] Toilet Paper Oil Filters. What happened?

[Hdefer]

I remembered all the hype and controversy about toilet paper oil  
filters from the 70's, when I accidently  ran into  this  site:

http://answers.edmunds.com/question-Who-sells-toilet-paper-oil-filters-these-days-49875.aspx

and found particularly interesting the answer from "Jack 137"

I am very curious if any of the list guys have had any experience  
with  these.
