HydraPak® Cap Water filter, 42 mm

A filtration solution essential for outdoor activities - especially those that last more than one day. The 42mm HydraPak Cap water filter is compatible with other solutions from this brand to help you stay hydrated on the go.

For both Seeker and Flux

You can easily combine the HydraPak Cap water filter with a diameter of 42 mm with a collapsible Seeker bag or flexible Flux bottles of the same diameter. In this way, you can easily turn these bags and bottles into a filtration solution. The result will be lightweight filter sets that can be used for various purposes.

Get drinking water even on the go

Although, especially in our conditions, we can often find harmless clean water in nature, the motto "trust, but verify" should apply. The Cap water filter is a great tool for that inspection. With the help of original HydraPak products, you can pour water into other containers through this filter, or drink freshly filtered water directly from them.

The complete HydraPak solution

The American brand HydraPak offers a comprehensive solution with the Cap water filter, which you can use not only with the Seeker and Flux products mentioned above, but also with UltraFlask or SkyFlask bottles. In any case, you will enjoy easy and quick water treatment, whether in the camp or directly in the field.

Lightweight and compact solution

With its mere 57 grams, it is one of the lightest filter solutions on the market. Such a filter takes up practically no extra space, whether you decide to store it separately in your backpack or screw it directly onto the Seeker or Flux products for transport.

Dust cover and powerful nozzle

The high-flow drinking nozzle has a dust cover that prevents the accumulation of dirt. In addition, you can open and close the powerful beverage nozzle with one hand without direct contact with dirty hands.

Safe and reliable

The HydraPak Cap water filter is completely safe and reliable. Removes Escherichia coli bacteria, Cryptosporidium parvum cysts and Giardia Lamblia (99.9 %) from approximately 1500 liters of water. It even protects against microplastics. Thanks to this, it meets or even exceeds EPA protocols. In addition, it is not harmful by itself. It does not contain bisphenol A (BPA) or PVC.

Compatible with 42mm thread
