homerunPET Water Fountain Filtration Technology

homerunPET employs activated coconut carbon filtration between cotton mesh layers, creating a comprehensive barrier against contaminants. This multi-layer approach captures particles at different sizes while addressing chemical and biological threats.

Four-Stage Filtration Process

The homerunPET filtration system works through sequential stages:

Stage 1: Pre-Filter Cotton Mesh – Captures visible hair, fur, and large debris particles before they reach finer filtration layers, extending overall filter lifespan.

Stage 2: Activated Coconut Carbon Layer – Removes chlorine, unpleasant tastes, odors, and organic compounds that affect water palatability. Coconut shell-based carbon offers superior adsorption compared to standard charcoal.

Stage 3: Secondary Cotton Mesh – Traps microscopic particles and sediment that passed through earlier stages, ensuring crystal-clear water output.

Stage 4: UVC LED Sterilization (CF20 Model Only) – Only the CF20 model includes advanced UVC LED technology that kills 99.9% of bacteria and viruses, providing hospital-grade water sanitation without chemicals. The other models (BF25M, BF10, WF20) do not include this feature.

This comprehensive approach addresses the three primary water quality concerns: physical contaminants (hair, debris), chemical pollutants (chlorine, heavy metals), and biological threats (bacteria, viruses).
