ETERNAL WORLD Calcium Sulfite Dechlorination Filter Material

As global consumers increasingly demand healthier bathing experiences, particularly in Europe and North America where the 

pursuit of a "skin-beautifying" shower experience has gained traction, water quality safety and residual chlorine removal have 

become core selling points for showerhead products. ETERNAL WORLD has developed a calcium sulfite 

dechlorination filter material (dechlorination balls) that stands out as an ideal choice for export shower handle filter cartridges 

and dechlorination boxes, thanks to its high-efficiency chlorine removal, long-lasting durability, and strong customization 

capabilities. The following analysis explores how this product meets the diverse needs of international markets from 

perspectives such as product performance, technological breakthroughs, international certifications, and application adaptability.

1. Differences in Bathing Water Needs Domestically and Internationally: 

From Basic Purification to "Skin-Beautifying" Demands  

In China, bathing water concerns primarily focus on the short-term irritation of residual chlorine on the respiratory system 

and skin. In contrast, markets in Europe and North America place greater emphasis on long-term health and skin-beautifying 

benefits. Residual chlorine can damage the skin barrier, accelerate moisture loss, and lead to sensitive skin issues. 

ETERNAL WORLD dechlorination balls achieve a 99% residual chlorine removal rate (maintaining high efficiency even after 2,500 

liters of water flow), converting residual chlorine into harmless calcium sulfate and calcium chloride. This provides consumers 

with a "zero-chlorine" bathing environment, aligning perfectly with the core demands of international users for gentle, 

skin-friendly care.

2. Core Product Performance: Efficient, Safe, and Long-Lasting  

Instantaneous Chlorine Removal, Durable Stability

ETERNAL WORLD dechlorination balls are made from high-purity calcium sulfite (90% purity), which reacts instantly with 

residual chlorine, achieving a 99% removal efficiency in just 0.1 seconds—far surpassing traditional materials like activated 

carbon. By integrating LSR (Long-Term Slow Release) intelligent technology and gradient temperature-controlled 

nanoporous sintering processes, the product’s physical strength and chemical stability are significantly enhanced, 

offering a lifespan of 6 to 12 months and eliminating the hassle of frequent replacements.  

Safe, Eco-Friendly, and Suitable for Sensitive Scenarios

The product uses no adhesive bonding, ensuring zero risk of secondary pollution. Its reaction byproducts 

(calcium sulfate and calcium chloride) are non-toxic and harmless, meeting drinking water safety standards. 

This makes it particularly suitable for mothers and infants, people with sensitive skin, and high-end bathroom products, 

fulfilling the stringent environmental and health requirements of European and American markets.  

High Temperature Resistance

The calcium sulfite material withstands high temperatures and features a surface with no visible pores, addressing the 

common issue of mold growth in traditional activated carbon filters.  

3. Customization Capabilities: Ultra-Small Sizes and Multi-Spec Compatibility  

To meet the compact design needs of shower handle filter cartridges and dechlorination boxes, ETERNAL WORLD offers a full 

range of sizes from Ø0.5mm to Ø10mm. The manufacturing breakthrough for Ø0.5mm ultra-fine particles overcomes the 

challenge of powdering during sintering at extremely small sizes, ensuring structural integrity even under high water flow. 

This technological advantage allows the product to be flexibly integrated into various irregularly shaped filter cartridges, 

aligning with the lightweight, modular design trends of mainstream showerheads in Europe and North America.

4. International Certifications and Brand Endorsement  

ETERNAL WORLD dechlorination balls strictly adhere to international water quality safety standards, having passed NSF-177 (performance testing for shower filter materials) and NSF-42 (drinking water safety certification). These certifications ensure the material’s non-toxicity and long-term reliability. Additionally, as a member of the WQA (Water Quality Association) in the United States, ETERNAL WORLD actively participates in shaping industry standards. Its technical expertise and product quality have earned recognition from over 1,000 clients worldwide.

5. Application Scenarios: Versatile Solutions from Shower Filter Cartridges to Dechlorination Boxes  

Shower Handle Filter Cartridges: 

Embedding 15-30g of dechlorination balls can meet the daily bathing needs of a household. It is compatible with 

high-water-pressure environments and reduces the risk of scale buildup and clogging.  

Portable Dechlorination Boxes: 

Supporting OEM/ODM customization, these can be paired with PP cotton filter layers for multi-stage filtration. 

Ideal for scenarios such as hotels and gyms, they cater to overseas users’ demands for convenient, ready-to-use solutions.
