in the box

  • 12 dual-layer filter cartridges
  • 4 filter cotton pads

The refill that keeps brook honest: 12 dual-layer cartridges and 4 filter cotton pads — the official ones, made for brook's stainless tray. Activated carbon tucked inside soft filter cotton quietly catches hair, dust and odors between rinses, so the water she drinks tastes like water.

Swap the cartridge about once a month — lift the tray, drop one in, done. Twelve swaps, twelve months. Your first cartridge came in the box with brook.

Fits every brook, both finishes.

A very high-quality product, though delivery was delayed by two days beyond the scheduled time... Still, I am satisfied thanks to the product's quality.

I ordered the fountain right away. And here are the filters for it. The same ones as in the package of the drinking fountain. They match the dimensions.

fair questions

Does it need filters?

A filter element comes in the box, ready to go. We're adding replacement packs to the store — and the steel tray rinses clean in seconds meanwhile, so nothing builds up while you wait.

How does charging work?

A 4000mAh battery charges over USB-C — cable included, just like your phone. Once it's charged, there's no cord anywhere near her water.

Is it actually quiet?

Yes — that's the point of the whole brand. It's designed to live next to your bed. If it ever gets noisy, the water is low; top it up and it settles.

How do I clean it?

Lift the steel tray, rinse, done. A cleaning brush is included for the corners. No maze of plastic parts, nowhere for slime to hide.

How fast is shipping?

Fast tracked delivery — typically 4–7 days anywhere in the US, free, with tracking on every order.

What if my cat ignores it?

Give it a few days — cats need time with new things. If it's still a no, you have 30 days from delivery: email us and we'll sort it out. See our refund policy for the plain-English details.
