1. Introduction
The Hskyhan Alkaline Water Filter Cartridge is designed to enhance the quality of your drinking water through a 7-stage filtration process. This system aims to increase the water's pH level, typically raising it by 0.5 to 2 points, resulting in a filtered pH range of 8-10 depending on your tap water source. It effectively reduces common impurities such as fluoride, chlorine, lead, dirt, and other harmful metals, while also removing unpleasant odors to provide clean and healthy water.
The cartridges are constructed from AS food-grade materials, ensuring they are BPA-free and designed for leak-free performance. The filtration media includes natural coconut shell activated carbon, ion exchange resin, and PP meltblown fiber.
2. Safety Information
- Always wash your hands thoroughly before handling the filter cartridge.
- Do not use hot water with the filter. Water temperatures above 100.4 ℉ (38 ℃) can compromise the filter's effectiveness and lifespan.
- Keep the filter cartridges out of reach of children.
- Ensure the filter is securely installed to prevent leaks.
3. Setup and Installation
3.1 Initial Filter Preparation
- Rinse the new filter cartridge under cold running water for approximately 1 minute.
- Submerge the filter in water and gently shake it for about 1 minute to remove any air bubbles and prepare the filtration media.
3.2 Installing the Filter
The filter features a simple design for easy installation. Align the filter with the designated slot in your compatible water pitcher and gently press it into place until it is securely seated. The filter on the cap is designed for easy insertion and removal.

4. Operating Instructions
4.1 First Use and Initial Filtration
For the first 3 pitchers of filtered water, it is normal to observe some carbon dust. This is harmless and can be used for watering plants or discarded. After these initial cycles, the water will be clear and ready for consumption.
4.2 Water Usage Guidelines
Filtered water is suitable for various uses, including cooking, preparing infant formula, making coffee, tea, and juice, creating ice cubes, and for pets. For optimal taste and quality, consume filtered water within 6 hours or store it in the refrigerator.

It depicts tap water entering the filter, where impurities like mercury, dirt, chlorine, lead, fluoride, and chromium are removed. The filtered water then flows into a glass, enriched with minerals like calcium, potassium, sodium, zinc, magnesium, and iron, and an improved pH level.
5. Maintenance
5.1 Filter Replacement
For consistent performance and healthy drinking water, replace the filter cartridge approximately every 40 gallons or once every month, whichever comes first. Regular replacement ensures optimal filtration effectiveness.

6. Troubleshooting
6.1 Carbon Dust in Initial Filtration
As mentioned in the setup instructions, it is normal for the first 3 pitchers of filtered water to contain some carbon dust. This is a result of the filter's activation process. Discard this water or use it for non-consumable purposes like watering plants.
6.2 Persistent Black Residue or Slow Flow
If black residue persists beyond the initial pitchers, or if the water flow is unusually slow, re-rinse and re-soak the filter cartridge as per the initial preparation steps. Ensure the filter is properly seated in the pitcher. If issues continue, the filter may be clogged or defective and should be replaced.
6.3 Compromised Water Taste
If the filtered water's taste is compromised, ensure you are consuming it within 6 hours or storing it in the refrigerator. Exposure to air at room temperature for extended periods can affect taste. Also, verify that the filter is not past its recommended replacement period.
