About This
- Advanced PFAS Reduction Technology Engineered specifically to tackle modern water contaminants, this CTO carbon block filter effectively reduces PFAS (forever chemicals), providing a higher level of safety for your family's water supply. Unlike standard carbon filters, our specialized formulation targets these persistent chemicals to deliver cleaner, healthier water throughout your entire home.
- Premium Coconut Shell Carbon for Pure Taste Made from high-quality 100% coconut shell activated carbon, this filter excels at absorbing chlorine, removing bad odors, and improving overall water taste. The dense carbon block structure ensures maximum contact time with water, effectively filtering out VOCs, turbidity, and fine sediments down to 5 microns without compromising water flow.
- Universal 20" x 4.5" Standard Fit Designed as a universal replacement, this cartridge fits all standard 20-inch x 4.5-inch whole house water filter housings. It is fully compatible with major brand casings, making it a hassle-free upgrade for your existing whole house filtration system.
- High Capacity & Long-Lasting Performance Built for durability and high-volume filtration, this 20-inch filter offers an extended service life suitable for large households. It maintains consistent water pressure while trapping contaminants, reducing the frequency of filter changes and lowering long-term maintenance costs.
- Protects Your Home & Appliances By removing corrosive chemicals and sediments before they enter your plumbing, the Purcooflow CTO filter helps protect your pipes, washing machines, and water heaters from damage and clogging. Go with the Pure Flow and enjoy a reliable supply of purified water for bathing, cooking, and washing.
