Automatic Pet Water Fountain – 3.5L UV Sterilization & Triple Filter

The PawVortex Automatic Pet Water Fountain is a 3.5L (118oz) automatic drinking fountain made from food-grade 304 stainless steel and BPA-free plastic. It is available in four variants: Style A (full fountain, plain design, $44.98), Style B (full fountain, cat print accent, $42.56), Replacement Filter ($9.40), and Replacement Pump ($13.97).

The fountain features built-in UV sterilization, triple-stage filtration (coconut shell activated carbon, ion exchange resin, and high-density cotton), and a wireless motion sensor that triggers fresh water flow when your pet approaches. It operates at ≤40dB and holds enough water for up to one week for a single cat. Rated 4.5 out of 5 stars based on 120 verified reviews. Suitable for cats of all breeds and dogs up to approximately 50 lbs, including multi-pet households with 2–4 animals. Ships from a US warehouse in 3–8 days. Free shipping on orders over $49. Returns accepted per PawVortex standard policy.

Most US pet owners refill water bowls twice a day without thinking about what’s actually in the water — chlorine, heavy metals, hair, and bacteria that accumulate within hours. The rise of automatic pet tech has made it easier than ever to solve this without adding to your daily routine. This automatic pet water fountain handles filtration, sterilization, and flow — automatically — so your dog or cat always has access to clean, moving water.

Why We Chose This for PawVortex

Before adding this to our lineup, we evaluated it across four criteria:

• Stability: The weighted stainless steel tray stays planted — no tipping during enthusiastic drinking sessions from larger dogs or multi-pet pile-ups.
• Debris filtration: The triple filter visibly captures hair, dust, and sediment within the first 48 hours. Coconut shell carbon handles chlorine and heavy metals; ion exchange resin softens mineral content; high-density cotton catches physical particles.
• Pet engagement: The wireless motion sensor consistently draws cats and hesitant drinkers to the fountain within the first day — especially effective for cats that ignore still water bowls.
• Cleaning: Full disassembly takes under 2 minutes. Every component is hand-washable with no tools required.

Outcome: Passed all four criteria. Added to the PawVortex pet water fountains lineup.

What Makes It Different

Most automatic pet water fountains use a single foam filter and a fixed-flow pump. This one combines UV sterilization, three-stage filtration, and motion-sensing flow in one unit — features typically found only in fountains priced significantly higher. The 304 stainless steel tray eliminates the plastic-chin-acne risk that affects many cats on standard plastic fountains. The UV sterilization light eliminates 99.9% of bacteria at the source, not just at the filter stage. For households with larger dogs needing a high-capacity option, the large dog water fountain from PETLIBRO offers a cordless, battery-operated alternative with radar sensing.
