Key differentiators:

• Zero filter design — patented filter-free purification (ZL202321876519.9) eliminates recurring filter costs. Traditional filters typically cost $5–10 per filter with 30-day replacement cycles, totaling $60–120 annually.

• Ultra-quiet at ≤26dB — below the 30–35dB industry average.

• Timed auto-water-change — 12/24/36 hour programmable cycles.

• UVC sterilization (ZL202321876517.0) in the wastewater tank.

• FDA-compliant tempered glass tray — zero lead/cadmium leach (test report S251223003001-1/-2).

• 4000mAh battery — KC safety certified, TUV Rheinland CB-tested cells.

• Wireless operation for flexible placement.

In traditional fountains, returned water mixes with clean water, causing cross-contamination and allowing hair and debris to cycle repeatedly. The C019's dual-tank design ensures that your pet always drinks from a fresh, uncontaminated source.

Dirty water is collected in a separate tank with UVC sterilization (ZL202321876517.0) to eliminate bacteria and odors before disposal. This is a proprietary solution not found in competing products from manufacturers that use single-tank recirculation designs.

Problem with traditional filters: Traditional fountains require filters that cost $5–10 per filter with typical 30-day replacement cycles ($60–120 annually) and often have inconsistent quality, leading to poor water taste and customer complaints.

Our solution: The C019 uses a physical water circulation purification system combined with UVC sterilization in the wastewater tank to maintain water quality without consumable filters.

Benefits: (1) Zero recurring filter costs. (2) No filter replacement anxiety. (3) Consistent water quality without filter degradation. (4) Lower environmental impact. (5) Higher customer satisfaction and fewer support tickets.

The C019's filter-free design eliminates this recurring expense entirely. Additionally, the C019's dual-tank design prevents the motor from running in dirty water, extending pump lifespan to 100,000+ hours under standard operating conditions (based on internal reliability testing).

This makes the C019 significantly more cost-effective over the long term while delivering superior water quality and quieter operation (≤26dB vs. typical 30–35dB).

Key features:

• Dual-power design — USB-powered with battery backup, supporting corded or cordless operation.

• Two water flow modes — raised fountain for bubbly water, lowered for gentle spring flow.

• 304 stainless steel or high-quality ceramic tray options.

C019 Sujie is the flagship model with patented dual-tank clean/dirty water separation (ZL202321876520.2), zero filter design, ≤26dB ultra-quiet operation, timed auto-water-change (12/24/36 hours), and UVC sterilization in the wastewater tank.

C015 Lingmeng features a unique patent-protected aesthetic design, 180° radar sensing (pet approaches = water flows), dedicated APP control, and UVC sterilization — but uses a traditional single-tank filtration system.

In short: choose C019 for ultimate water purity and zero consumables; choose C015 for modern design, radar interactivity, and smart APP features.

Choose C019 if you want the ultimate in water purity (dual-tank separation), zero filter costs, ultra-quiet operation (≤26dB), and smart features like timed auto-water-change and UVC sterilization.

Choose C016S if you need wireless battery-powered operation with 3 modes (sensor/intermittent/continuous) and prefer a full stainless steel design.

Choose C011AS if you want the simplest, most hygienic stainless steel fountain with no complex electronics — the submersible pump design maximizes water utilization and the structure has zero cleaning dead zones.

Choose C015 Lingmeng if you prioritize modern aesthetics, radar sensing, and the highest level of APP control — it's the most intelligent model in the lineup.

Replacement modules are available through our spare parts program for B2B partners. The UVC lamp is integrated into the wastewater tank assembly, making it easy to replace without disassembling the main unit. We recommend annual inspection for optimal sterilization performance.

The C011AS and C016S are also exceptionally quiet thanks to our silent pump technology (patent ZL202321876521.7), operating around 28–30dB.

C015, C004, C005, and C006 operate at 30–33dB, which is still below the industry average of 30–35dB.

All our pumps are designed with low-noise operation as a priority, and we test each unit in our noise testing chamber to ensure consistency.
