Culligan IC-100 Inline Water Filter

[henrion]

If it says "The Culligan IC-100 inline water filter life is up to 2,500 gallons or one year depending on water usage and water quality." does that mean if I only use it once for an entire year, after that year it would be wise to throw it out? What does the "or one year" really mean?

The life expentancy information that is on our site is Culligan's
recommendation. "Water filter life is up to 2,500 gallons or one year
depending on water usage and water quality" means that you should
replace your filter after 2,500 gallons or one year, depending on
which comes first. If you use 2,500 before the year is up, you need
to replace your filter. If you have had your filter installed for one
year, but haven't used 2,500 gallons, you still need to replace the
filter.
