1. Introduction
The WRELS Personal Water Filter is a compact and portable filtration system designed for outdoor activities such as camping, hiking, and emergency situations. It utilizes advanced hollow fiber ultrafiltration membrane technology to provide safe drinking water by filtering out harmful contaminants. This filter is certified by the US NSF, ensuring reliability and performance.
2. Product Overview & Components
The WRELS Personal Water Filter is engineered with food-grade materials for safety and durability. Its internal structure includes advanced filtration components to ensure effective purification.
- Water Outlet: The point from which filtered water is consumed.
- Dust Cover: Protects the water outlet from dust and debris when not in use.
- Food-Grade ABS Shell: The outer casing, ensuring quality, sturdiness, and durability.
- Food-Grade ABS Inner Shell: Provides an additional layer of protection for drinking water safety.
- Ultrafiltration Membrane Fibers: The core filtration element, designed to filter out 99.999% of microorganisms and bacteria.
- Water Inlet: The opening where raw water enters the filter for purification.
3. Setup
Before first use, and for optimal performance, follow these initial setup steps:
- First-Time Use: Rinse the filter cartridge thoroughly with 50-100ml of clean water. This primes the filter and flushes out any manufacturing residue.
- New Filter Break-in (First 0-15 days of use): After each use during this period, rinse the straw with clean water 2-3 times and then invert it to air dry. This helps optimize filter performance.
4. Operating Instructions
The WRELS Personal Water Filter offers versatile usage options for various outdoor scenarios.
- Direct Drinking: Use the filter as a straw to drink directly from a freshwater source. Ensure the water inlet is submerged and the water outlet is used for drinking.
- Bottle Connection:
- The filter features a 28mm threaded end, compatible with standard Coca-Cola and Sprite bottles.
- It also has a 30mm threaded end, suitable for most mineral water bottles.
- Simply attach the filter to the bottle opening and drink directly from the filter.
- Water Bag Compatibility: The filter can be connected to a water bag for gravity filtration or for squeezing water through the filter into another container.
5. Maintenance
Regular cleaning and proper storage are essential to maintain the filter's effectiveness and extend its lifespan.
5.1. Cleaning Method
- Unscrew the water tap and inlet knob from the filter.
- Position the water tap and water inlet for easy access.
- Link a clean water bottle (or other clean water source) to the filter's outlet.
- Rinse the water purifier by backflushing clean water through it. This helps dislodge trapped particles.
5.2. Limescale Removal (for Daily Use)
If limescale builds up, soak the filter in white vinegar for 3-5 minutes. After soaking, rinse thoroughly 3 times with clean water and let it air dry.
5.3. Flushing System
Regular flushing helps wash away mud and sand, which extends the service life of the filter element and maintains optimal flow rate.
5.4. Storage
After cleaning, ensure the filter is completely dry. Store it in a clean, dry, and cool place, away from direct sunlight and sharp objects to prevent damage and maintain hygiene.
6. Troubleshooting & Important Notes
- This filter is designed for freshwater sources free from chemical pollution. Do not use it with saltwater, chemically treated water, or water containing known toxins.
- Filter Cartridge Replacement: The WRELS Personal Water Filter features a one-piece design, and the internal filter cartridge is not replaceable. The entire unit should be replaced once its filtration capacity (3000L) is reached or if it becomes damaged.
- Unsuitable Liquids: Do not filter cola, tea, vinegar, alcohol, milk, or other liquids containing acidic dyes or pigments. This is considered a destructive test and is not covered by warranty. Filtering such liquids may only make them clearer but can severely damage the filter's membrane and render it ineffective for water purification.
- General Safety: Always use with freshwater sources. Do not filter chemically contaminated water, saltwater, or water with known toxins.
- Children: Keep out of reach of small children to prevent choking hazards from small parts.
- Intended Use: Use this product only for its intended purpose of filtering freshwater. Misuse may lead to health risks.
