Pros & cons

  • Larger footprint than single-tank systems, needing dedicated space
  • Higher upfront cost compared to basic sediment-only filters
  • Not designed for well water with iron or heavy sediment without pre-filtration

Living with it day to day

The Pelican Water PRO OFM CAT1 Whole Home Filtration System is engineered for homeowners who want comprehensive, point-of-entry water treatment without the hassle of salt-based conditioning or constant filter changes. Designed to handle municipal water supplies, this system targets chlorine, chloramines, and hundreds of other contaminants that can affect taste, odor, and overall water quality throughout the entire house. Unlike small pitcher filters or single-tap solutions, the PRO OFM CAT1 treats water at the point where it enters your home, ensuring that every faucet, showerhead, and appliance receives filtered water, from the kitchen sink to the washing machine to the water heater itself.

At the core of this system is a high-capacity filtration media bed that uses a catalytic carbon blend specifically formulated to reduce chloramine, a chemical increasingly used by municipalities that traditional carbon filters struggle to remove effectively. This CAT1 media is paired with a durable fiberglass tank and a digital control valve that automates backwashing cycles, keeping the media bed clean and performing at peak efficiency without requiring manual intervention. The system is sized according to household demand, taking into account factors like number of bathrooms, water usage patterns, and flow rate requirements, so that water pressure remains strong even during high-demand periods like morning showers or laundry day. Installation typically occurs at the main water line, and the unit is built to handle years of continuous use with minimal maintenance beyond periodic media replacement, which is generally needed far less frequently than standard cartridge-based filters.

Beyond contaminant reduction, the Pelican PRO OFM CAT1 appeals to households concerned about long-term value and environmental impact. Because it doesn't rely on salt or chemical additives, it produces no wastewater brine discharge, making it a more sustainable choice compared to traditional water softeners, and it requires no bags of salt to lug and load regularly. Homeowners often notice improvements in the taste and smell of drinking water directly from the tap, better-tasting cooking water, and gentler water for bathing that doesn't leave behind the chemical residue associated with heavily treated municipal supplies. Backed by manufacturer warranties and designed for straightforward professional or DIY installation, this whole house filtration system represents a long-term investment in water quality that protects both the people in the home and the plumbing infrastructure that delivers water to every fixture.
