Sediment water filter exclusively used in the
Athena only. It is the filter in position #1 in your Athena (it goes
inside the left filter housing door). It is a fiber filter that removes
particulate. In water treatment all sediment filters have ratings
expressed as either nominal (typical pore size) or absolute (all pores
size at or smaller than). With 1 micron absolute filtration this new
and improved sediment filter is capable of filtering out contaminants
up to 5 times smaller than that of the original filter. The filter life
indicator on the Athena will still continue to monitor the life of the
filter and should be replaced when the digital display reads 9999,
after approximately 500 gallons have run through the filter. A modified
filter stand is included with your order to replace the filter cup in
use in Athena models sold prior to August 2009
