Fits the PureSpring fountain

A fountain is only as fresh as its filter.

Over a couple of weeks, fur and dust and minerals build up. The water starts to look cloudy, a film creeps over the bowl, and your cat quietly drinks less. A fresh filter keeps the water clear, soft and clean, so they keep coming back to it.

The hard part is not swapping the filter. It is remembering to. If you are the kind of owner who wants this handled before it slips your mind, subscribe and a fresh 8-pack arrives every 2 months at 25% off. No reminders, no last-minute reorders, no slimy bowl.

  • Cleaner water, every day

    The triple-layer filter traps loose fur, dust and grit before it floats in the bowl, so the water your cat laps up stays clear instead of cloudy.

  • They keep drinking

    Cats turn their nose up at stale, off-tasting water. Fresh filtered water tastes soft and clean, so your cat keeps coming back to the fountain.

  • No more slimy buildup

    That film that creeps over the bowl after a couple of weeks comes from an old, clogged filter. A fresh one keeps the whole fountain looking and smelling clean.

  • Swaps in a couple of minutes

    Lift the pump cover, pop the old filter out, click the new one in. No tools, no mess, done before the kettle boils.

  • Never run out

    A fresh 8-pack arrives automatically every 2 months, so your fountain is never left with a tired filter.

  • Save 25%

    $29.99 per 8-pack on subscription instead of $39.99. It is the lowest price per filter we offer.

  • Free shipping

    Every subscription delivery ships free, straight to your door.

  • Full control

Don't have the fountain yet?

These filters are made for the PureSpring stainless-steel fountain: the quiet, slime-free way to keep your cat drinking fresh water all day.

Filters and subscription, your questions

How often should I change the filter?

Every 2 to 4 weeks, depending on how many cats drink from it. The 4-pack lasts about a month and the 8-pack about two, which is exactly the subscription cadence.

How does the subscription work?

Choose Subscribe & Save and a fresh 8-pack is delivered every 2 months for $29.99 instead of $39.99 one-time. You can skip, pause or cancel anytime from your account.

Will these fit my fountain?

Yes. They are made for the PureSpring stainless-steel fountain and click straight into the pump housing.

What is the filter made of?

Three layers working together: cotton catches loose fur and debris, activated carbon helps the water taste clean, and ion-exchange resin softens it. Together they keep the bowl clear.

Can I cancel the subscription?

Anytime, in a couple of clicks from your account. No fees and no questions. You are always in control.
