I agree to all of the above except for the coffee filter.  If it is 
an unbleached Malita brand filter, I agree.  If it is any other 
brand, especially a Mr. Coffee, you are actually adding contaminants 
to your solution.  The Mr. Coffee has some kind of coffee flavor 
improver imbedded in the filter.  Try making coffee on a Mr. Coffee 
sometime with another brand of filter to prove the point.  Been there 
done that.  With the Malita filter you have the best odds of doing 
your solution a favor.  I still maintain that lab filters are the 
best and they are cheap.  Sometimes you can get some from a local lab 
just by asking.  I got some from the Sheriffs Dept. Forensic Lab just 
by asking once.  Got enough to do more batches than I will ever need. 
Most lab supply houses have 'em down to the less than micron size.
