After dinking around with filters, cheap to expensive and a cousin that had a Falcon for over 30 years with a Frantz, I'm beginning to think that rolled tissue like toilet paper and center pull towels are the best a filtering. Another cousin is finishing an experiment with center pull towels purchased at Costco at 12 bucks for four and putting one in a housing has out performed three very expensive filters with heaters, spinners and fancy advertising. Sometimes simple is better and because it's right in front of you, you just don't see it.
