No-Installation Hanging Bathtub Filter

Modular, Customizable Filter Media Redefine the Shower Experience: ETERNAL WORLD's Formula for the No-Install Bathtub Filter Boom

As consumers increasingly pursue higher-quality living standards, no-install hanging bathtub filters are rapidly gaining popularity in the bathroom market for their convenience, efficiency, and eco-friendliness. In this emerging field, ETERNAL WORLD’s hybrid shower formula filter media stands out with its highly customizable design. By scientifically blending multiple core materials in specific ratios, it meets the personalized needs of various customer groups and serves as a key technological foundation for improving shower water quality.

I. Functional Analysis of Core Filter Media

ETERNAL WORLD’s hybrid formula filter media is composed of seven core materials, each engineered to address a specific water quality issue:

• Calcium Sulfite Dechlorination Media: Rapidly neutralizes residual chlorine in water, reducing skin irritation and respiratory sensitivity.

• KDF Microporous Antibacterial Media: Utilizes the redox reaction of copper-zinc alloy (KDF55) to inhibit bacterial growth and extend filter life.

• Zeolite Media: Adsorbs heavy metal ions and odors to improve water clarity.

• Maifan Stone Media: Releases trace elements and balances mineral content in water.

• Vitamin C (VC) Ceramic Media: Applies antioxidant slow-release technology to soften water and enhance bathing comfort.

• Tourmaline: Releases negative ions to activate water molecules.

• Terahertz Ceramic Media: Uses far-infrared effects to stimulate microcirculation and enhance water vitality and health benefits.

These materials are not combined in a fixed formula; instead, their ratios are dynamically adjusted based on customer requirements, application scenarios, and budget considerations—creating “precisely matched” solutions.

II. Custom Formulation Strategy: From Needs to Scientific Proportions

ETERNAL WORLD’s technical team follows a systematic process—needs analysis → scenario modeling → formula design—to deliver tailored media compositions for different clients:

1. Economy Plan: Cost-Effective Solutions for Basic Filtration

For price-sensitive markets (e.g., rural or entry-level distribution channels), the formula reduces the proportion of high-cost materials like dechlorination or terahertz ceramics, while increasing foundational materials like zeolite and tourmaline (up to 60%-70%). Particle size is also optimized to improve flow rate and reduce production costs.

2. Certification Plan: Compliant with International Standards (e.g., NSF-177)

For clients targeting exports to Europe, North America, or premium markets, the formulation must meet stringent NSF-177 requirements on chlorine reduction and heavy metal adsorption. In such cases, calcium sulfite and KDF content is increased to over 50%, supported by KDF microporous antibacterial media to ensure water safety and testing compliance.

3. Function-Enhanced Plan: Priority on Antibacterial or Dechlorination Needs

• Antibacterial Use Cases (e.g., hotels, gyms): Higher proportions of KDF are combined with slow-release VC ceramic technology to create a dual protective mechanism.

• High-Chlorine Environments (e.g., municipal water with excess chlorine): Calcium sulfite content exceeds 50%, paired with zeolite to adsorb remaining chloramine, achieving rapid purification.

III. Formula Adaptation to Sales Channels & Flow Rate Scenarios

The ratio of filter materials is also adapted to real-world usage environments, especially considering differences in flow rate and installation settings:

1. High Flow Scenarios: Commercial Channels & Bulk Orders (Hotels, Public Showers)

To support high water volumes, ETERNAL WORLD uses large-particle filter media to reduce water resistance while increasing the density of KDF and calcium sulfite, ensuring effective dechlorination and antibacterial performance even at high flow speeds.

2. Long-Term Slow Release: Home Use & High-End Markets

Household users prioritize filter lifespan and continuous purification. These formulas incorporate more microporous structures to slow the media’s dissolution rate and extend the usage cycle, while increasing tourmaline content to enhance water activation.

IV. Technical Strengths & Service Support

ETERNAL WORLD’s core strength lies not only in material science but also in its agile customization capabilities:

• Provides formulation simulation testing, replicating local water conditions in the lab to optimize media combinations.

• Supports customization of media particle size and specifications, enabling fast iteration for OEM/ODM clients.

• Offers filter replacement cycle calculation models, helping clients develop differentiated marketing strategies (e.g., “long-life” or “fast-replace” cartridges).

🏆 Conclusion

In an era where consumption is upgrading and personalization is expected, ETERNAL WORLD’s hybrid shower filter media—through modular design and precise formulation—is redefining what’s possible for no-installation water filters. Whether catering to value-driven mass markets or functionality-focused premium sectors, ETERNAL WORLD strikes a balance between water purification and user experience, establishing itself as a driving force in the evolution of the bathroom industry.
