key features
✅ Simple Installation
Designed for standard 3/4-inch pipe connections, this filter is DIY-friendly and does not require professional tools or plumbers. Installation can be done in minutes, even for first-time users.
✅ Low Maintenance & Long Lifespan
Each cartridge lasts up to 6 months, depending on water quality and usage. With an average annual maintenance cost of just 300 RMB (~$40 USD), it's far more economical than other complex filtration systems.
✅ Safe & Durable Materials
The filter housing is made from food-grade stainless steel, resistant to corrosion and safe for household use. It withstands water temperatures up to 60°C, making it reliable even in varied environments. Compared to plastic models, our filter lasts up to 50% longer, reducing replacement frequency and long-term cost.

How Single-Cartridge Water Filter Works
Our single-stage water filter uses dual-action filtration:
- Mechanical filtration traps particles, rust, and sediment as small as 5 microns.
- Activated carbon adsorption reduces chlorine, odors, and organic impurities that affect the taste and smell of your water.
This simple yet effective design ensures better water quality for daily household use-especially for dishwashing, hand washing, and protecting kitchen appliances.

How to Choose the Right Filter Cartridge
The cartridge is the heart of your filter system. Here's what to look for:
Material:
- Activated Carbon: Reduces chlorine, odor, and organic chemicals.
- KDF: Removes heavy metals like lead and mercury, and helps prevent bacterial growth.
Filtration Layers: More layers mean higher filtration precision.
Replacement Cycle: A high-quality cartridge should last 6 to 12 months under normal use.
Installation & Maintenance Tips
When selecting a water filter, make sure it's easy to install and maintain:
- Check for tool-free installation and compatibility with standard pipes.
- Confirm availability of replacement cartridges and reliable after-sales service.
- Choose filters with clear indicators or guidelines for when replacements are needed.
Applications
- Kitchen sinks
- Under-sink filtration systems
- Whole-house pre-filtration (for small households)
- Apartments or homes with moderate water quality concerns
