Gravity-Fed Outdoor Water Purification System (6L)
The Gravity Water Purification System delivers clean, great-tasting water for groups, families, or emergency use — all through the power of gravity. With a generous 6 L capacity, it purifies water from natural or municipal sources without the need for power, batteries, or manual pumping.
At the core of the system is an Advanced 3 In 1 Survival Straw offers reliable water purification in a lightweight and user-friendly design. Its 3-stage filtration system effectively removes 99.99999% of bacteria, protozoa, and other contaminants, providing safe drinking water during camping, hiking, travel, or emergency situations. The detachable feature allows for easy cleaning and filter replacement, extending the product's lifespan and ensuring consistent performance.
The gravity system is designed for hands-free operation — simply fill the upper reservoir, hang or set it up securely, and let gravity pull water through the filter into a clean container below. It’s an efficient, low-maintenance way to produce safe drinking water wherever you are.
The included portable filter can also be detached and used independently as a personal straw filter, giving you added versatility for hiking or individual use.
Key Features:
3-Stage Filtration: Combines a 0.1-micron hollow fiber ultrafiltration membrane, coconut shell activated carbon (GAC), and double PP fiber filters to remove bacteria, protozoa, heavy metals, chlorine, and odors.
Detachable Design: Both ends can be disassembled for easy cleaning and filter replacement, enhancing reusability and cost-effectiveness.
Versatile Use: Can be used directly as a straw, connected to standard disposable water bottles, or integrated into a gravity-fed filtration system.
High Flow Rate: Delivers up to 500ml per minute, ensuring quick access to purified water.
Long Lifespan: Capable of filtering up to 20,000 liters of water with a very clean water and frequent backwashing, making it suitable for prolonged use under ideal conditions.
