• Vet-Recommended Filtration System: Triple-layer filtration combines 100% organic cotton pads with food-grade coconut charcoal to remove 99.7% hair, sediments, and odors, ensuring fresh-tasting water for cats/dogs.
• Hassle-Free Monthly Maintenance: Each 6-pack covers 6 months of use (1 filter 1 pad/month). Pre-rinsed design saves 15 mins setup time - simply flush with cold water for 30 seconds to activate carbon absorption.
• Compatibility: Compatible with all EchoSmile 4L pet fountains and 90% similar models. Please make sure the pet fountain filter replacement size is compatible with your pet fountain before purchase.
• Eco-Safe Material Assurance: BPA-free & heavy metal tested. Coconut shells activated at 1800F create micro-pores (3x denser than wood-based charcoal) for superior impurity retention without fiber shedding.
• Leak-Proof Performance: Precision-cut edges prevent bypass flow. Reinforced resin frames maintain structural integrity under continuous water pressure (tested 500 hours).
