Their ceramic filtration was featured as "Best buy" by Consumers
Digest Magazine in July/August 2003 issue however, the company has
been around since 1827. Their clients are major world's institutions
using their filters in the third world countries where microbiological
concern is a problem.
I call them for advice on which filter model to buy and they suggested
me the least expensive based on my city water contaminants. They even
suggested me to buy less expensive carbon filter since my city water
have to comply with EPA standards for microbiological contaminants.
