PureFlow Replacement Filters (7-Pack)

Six months of clean, fresh water — in one click.

Your fountain only works as well as its filter. Once the filter clogs with hair, food bits, and biofilm, water tastes off, smells stale, and your cat stops drinking — exactly when hydration matters most.

This 7-pack keeps your PureFlow fountain running clean for about six months. Replace every 3–4 weeks, or set up auto-delivery and never think about it again.

Why pet parents subscribe

• Skip the "uh-oh" moment. No more realizing on Sunday night that your cat's been drinking gross water for two weeks.
• Save 15% with subscription. Auto-delivered every six months at $25.49 instead of $29.99 — cancel, pause, or change frequency anytime.
• Better hydration = healthier cat. Fresh filtration encourages drinking, which supports kidney health, urinary tract function, and prevents UTIs.

What's in the box

• 7 × PureFlow replacement filters (5-stage filtration: cotton, activated charcoal, ion-exchange resin, fine mesh, sponge)
• Each filter lasts 3–4 weeks with normal use
• Approximately 6 months of supply

Compatibility

Fits the PureFlow Wireless Cat Fountain. (Not compatible with other brands — generic filters may seem cheaper but don't seal properly and let unfiltered water bypass the system.)

When to replace

Every 3–4 weeks, or sooner if you notice any of these:

• Water flow has slowed
• Visible residue or discoloration on the filter
• Your cat is drinking less than usual
• Pump is louder than normal (clogged filters strain the motor)

Specs

• Filter life: 3–4 weeks per filter
• Pack lasts: ~6 months with regular replacement
• Filtration stages: 5 (cotton, charcoal, ion-exchange, mesh, sponge)
• Material: Food-grade, BPA-free
• Compatibility: PureFlow Wireless Cat Fountain only

Pro tip: Rinse new filters under cold water for 30 seconds before installing. Removes loose carbon dust and primes the filter to start working immediately.
