Giant acts of kindness can go a long way. Donating, volunteering, and even giving a bunch of techs brand new drills: those are all the good deeds that make the world a better place... and makes people squeal out of shear happiness :)
I love my PUR sink mounted water filter so much. It was so easy to install even I could do it. I wrote a whole review on it you may want to check out if you are looking for a new sink mounted water filter.
