How often do the filters need replacing?

The carbon filter pair is rated for up to 6,000 gallons and the fluoride pair for up to 1,000 gallons. In a household drinking a gallon a day, the fluoride stage is the one you'll change first, roughly every two to three years.

Does it remove fluoride?

Yes, it ships with a dedicated fluoride filter stage. The fluoride pair is rated for up to 1,000 gallons, well short of the carbon stage's 6,000-gallon rating.

Do I need to install plumbing?

No. It is a freestanding gravity tank: fill the top, water passes through the filters, and you draw it from the spigot. No hookup or electricity is required.

How much water does it hold?

2.25 gallons, about 8.5 liters. That is roughly three times a standard 10-cup pitcher.

Is $89.99 a good price?

It is the best new price among the two stores listing it new as of November 6, 2026. Check whether the listing includes both filter pairs, since replacements add to the long-term cost.
