Butelka z filtrem piaskowym Grayl UltraPress

The Grayl UltraPress filter bottle will give you contaminant-free and safe water in any latitude.

Grayl UltraPress bottle - safety first

Water, obtained from adventurous sources, although clean and drinkable at first glance, may contain dangerous bacteria and viruses. Therefore, it is good practice to purify it every time. The UltraPress bottle is perfect for this.

Grayl UltraPress bottle - clean water in just 8 seconds

According to the manufacturer, the Grayl UltraPress bottle can purify 410 ml of clean water in 8 seconds. The principle of the vessel is simple. You need to unscrew the inner module, and take water into the outer one. By "merging" the two parts again, the water, under pressure, will seep through the carbon filter. In turn, this one will clean it of harmful microorganisms. Filtration efficiency is estimated at 99%.

Grayl UltraPress bottle and SimpleVent™ cap.

The vessel is equipped with a SimpleVent™ cap. It performs three functions. First, it drains air during filtration. Second, it ensures that water most simply does not spill out of the bottle. Third, its mouthpiece resembles a "spout", so you can drink from the bottle with one hand. Undoubtedly a useful feature.

Grayl UltraPress bottle - functional and durable

Grayl UltraPress is made of rough, well-grip plastic. The material is durable and resistant to mechanical damage. The manufacturer claims that the bottle, when filled with water, should withstand a fall on a concrete surface from a height of about three meters.

A filter that serves for years

The manufacturer suggests that the carbon filter placed in the vessel should be replaced when it has purified about 250 liters of water, or when three years have passed since the bottle was first filled. The filter, unused and hermetically packed, can be used even ten years after manufacture.
