The total capacity of the assembled outer and inner bottle structure.
Approximately 500 ml of filtered water can be collected inside the inner press bottle after filtration.
A reusable bottle structure made with lightweight materials suitable for portable outdoor carrying.
The bottle operates through manual downward pressure with no batteries, charging, pump, or electrical connection.
The outer bottle holds source water while the inner bottle receives filtered water as it is pressed downward.
Use the clearest available freshwater source whenever possible for smoother pressing and longer filter life.
3-Stage Filtration System
02Three Filtration Materials in One Compact Bottle
As the inner bottle is pressed downward, source water passes through PP cotton, coconut shell activated carbon fiber, and a hollow fiber ultrafiltration membrane before entering the clean-water chamber.
Three filtration materials work together inside the bottom of the inner press bottle.
Acts as the first filtration layer to help intercept sediment, suspended particles, soil, and other visible impurities.
Helps reduce unpleasant taste, odor, chlorine, and certain chemical impurities for a more enjoyable drinking experience.
Provides high-precision physical filtration through a medical-grade hollow fiber ultrafiltration membrane.
Key Product Indicators
03Hollow fiber ultrafiltration membrane designed for high-precision physical filtration.
Actual filter life may vary depending on water quality, sediment level, frequency of use, and maintenance.
The rated flow is approximately 4.7 liters per minute under suitable operating conditions.
The inner press bottle holds the filtered water after the pressing process is completed.
A portable manual filtration system designed for outdoor carrying and emergency storage.
Approximately 27 cm in height with an 8 cm diameter at the base.
Store the unused product in a clean, cool, ventilated, and dry location.
Suitable for outdoor adventures, international travel, fishing, preparedness kits, and uncertain freshwater access.
How to Use
04Ready. Fill. Press. Drink.
The manual pressing design filters freshwater directly inside the bottle without electricity, batteries, pumping equipment, or a separate collection container.
Hold the outer bottle securely and pull the inner press bottle upward to prepare the system for filling.
Fill the outer refill bottle with the clearest available river, stream, rain, spring, or well water.
Position the inner bottle correctly and apply steady downward pressure as water moves through the filter.
Open the drinking lid after pressing and drink directly from the clean-water chamber.
Care & Maintenance
05Hand-wash the outer refill bottle and inner press bottle with warm, soapy water before using the product for the first time.
Never wash the filter cartridge with soap, detergent, bleach, or other chemical cleaning agents.
The filter may be gently rinsed with clean water when needed. Do not scrub or use abrasive cleaning materials.
After each use, remove as much water as possible from inside the filter and bottle components.
Let the filter dry completely in an open, cool, well-ventilated place before reassembly or long-term storage.
Storing the filter while it is still wet may cause odor. Always dry the internal filter thoroughly after use.
The cartridge will become increasingly difficult to press as it reaches the end of its usable filtration capacity.
Replace the cartridge when water flow stops, pressing becomes unusually difficult, or the rated filtration capacity is reached.

How the Filter System Works
Water is added to the upper chamber and moves through the center filter by gravity. After filtration, water collects in the lower chamber and is ready to dispense from the spigot.
Add water to the top chamber. The system works without electricity, plumbing, or pressure.
Water naturally flows downward through the center filter element, where the filtration process takes place.
After passing through the filter, water collects in the lower chamber for storage and daily use.
Open the spigot to pour filtered water for drinking, cooking, or everyday hydration.
Filter Replacement Guide
Replacing filters on time helps your filtration system keep working properly. It also helps maintain water flow, drinking water taste, and everyday use confidence.
Filter life may vary by water quality, usage frequency, and total water volume filtered.
Replace the filters when they reach the rated lifespan listed for your filter model.
If filtering takes much longer than usual, clean or replace the filters as needed.
If unwanted taste or smell becomes noticeable again, it may be time to replace the filters.
Rain, river, stream, or well water may shorten filter life compared with regular tap water.
Choose filters that match your filtration system, filter series, and setup.
Prime, rinse, or flush new filters according to the product instructions.
Make sure washers, seals, and threaded parts are installed correctly.
Empty and clean the upper and lower chambers before installing new filters.
If your system uses paired filters, replace matching filters together when needed.
Write down the replacement date and set a reminder based on your usage.
