• Advanced carbon block: Uses 100% Sri Lankan coconut shell carbon block with more micropores and twice the surface area to improve water taste over mixed charcoal types.
• Tool-free installation: Precision manufacturing means the filter installs without tools and helps avoid leaks from loose or ill-fitting replacements.
• Trackable service life: Ships with month install stickers to monitor the recommended capacity of 300 gallons or six months depending on water conditions.

Who It's For
