Penguin Water 4.5" X 20" Ultra Filter System

Not every home needs a tank-based system — sometimes a single, high-capacity cartridge is exactly right. The Penguin Water 4.5" x 20" Ultra Filter System installs at your main line and runs the whole home through one large-format cartridge you choose for your water: sediment to clear grit and rust, or carbon to cut chlorine taste and odor. Simple, effective, and backed by a team that answers when you call.

Why Homeowners Choose This System

• One-Cartridge Simplicity — a single high-capacity 4.5" x 20" housing filters the whole home with an easy periodic cartridge change.
• Choose Your Media — sediment for grit and rust, or carbon for chlorine taste and odor.
• No Power, No Backwash — nothing to plug in and no wastewater cycle.
• Backed by a Team That Answers — 24/7 support and a 10-year limited warranty.
