Waterdrop Gravity Water Filter Straw for Travel and Camping

Performance & Capabilities

Premium 5-Stage Filtration System

The Water Filter Straw incorporates premium-quality coconut shell activated carbon, an 0.1 um ultrafiltration membrane, and other superior materials to effectively reduce harmful substances like chlorine, particulates, sediment, and bad taste and odor in water. This ensures water safety and an enhanced drinking experience.

Professional Combination for Outdoor Use

The Waterdrop Gravity Water Filter Straw is paired with a 1.5 gal Gravity-Fed Water Bag, creating a perfect combination for outdoor activities and first aid survival. The large-capacity water bag can hold up to 11 bottles of 500 ml purified water, meeting your all-day outdoor water needs.

Extended Lifespan and High Flow Rate

The Waterdrop Filter Straw can provide safe drinking water up to 1,400 gallons (5,300 liters) and ensures a maximum water flow rate of up to 700 ml/min, enhancing your outdoor water drinking experience.

Recyclable and Maintenance-Easy

With its innovative backwash purifier function, the filter straw can be kept clean and is recyclable, safe, and pollution-free. When the water flow decreases or the filter has been used for a long time, simply remove the mouthpiece and flush it with clean water using a standard water bag or a pop bottle with a 27.5mm thread diameter.

Versatile and Convenient Uses

The Water Filter Straw can be connected to water bags or water bottles to filter water for drinking. Both ends can be disassembled and connected to offer you clean drinking water anytime and anywhere.

Warm Prompt

When using the gravity bag for filtering water, always turn on the drainage valve first to empty the air from the hose before connecting it to the straw to avoid vacuum and no water flow.

Multi-Scene Application

As a necessity for outdoor water purification, the Waterdrop Gravity Water Filter Straw is applicable to a variety of situations, including hiking, camping, domestic and international travel, and emergency preparedness for natural disasters.
