Will this cap fit my AquaBrick?

It fits AquaBricks made in 2022 or later. Older containers use a different cap, so check the manufacture date before buying.

Does the cap include a filter?

No. It is the cap only. You need the AquaBrick container and the matching filter element to actually clean water.

Fill the AquaBrick, screw on the cap with the filter in place, and let gravity pull water through into a bottle or pot. No pumping or power is needed.

Can I use it as a standalone water filter?

No. It only works attached to an AquaBrick container. Without one it cannot hold or filter water.

Is it worth it if I already own an AquaBrick?

If your AquaBrick is a 2022-or-later model and you want filtered water from stored supplies, it adds filtering with no extra gear to carry.

How fast does water come through?

Gravity-fed flow is steady but slower than a pump filter. Expect to fill a bottle over a few minutes rather than seconds.

Where is the Filter Cap – AquaBrick Filter System cheapest?

Our take on the Filter Cap – AquaBrick Filter System

The Filter Cap is the piece that turns a Sagan Life AquaBrick water storage container into a gravity filter. You fill the AquaBrick, screw on the cap, and water drains through the filter into a glass, bottle or pot. It fits only AquaBricks made in 2022 or later, so older containers need a different cap. It is a small add-on rather than a standalone purifier: without an AquaBrick and a filter it does nothing. Buyers who already store water in AquaBricks get a simple way to make that stored water drinkable without a separate pitcher or pump system.

Pros

Turns an existing AquaBrick into a gravity filter with no pump or power

Cons

Useless without an AquaBrick and a compatible filter
Gravity flow is slower than a pressurized pump
Little margin for error: a lost cap sidelines the whole system
