ACF FIBER FILTER

Starts with clean water

ACF filtration for the purest scalp care experience.

💧 What is an ACF Filter?

An ACF (Activated Carbon Fiber) filter is a high-performance filtration system made from activated carbon fibers.
It features a surface area more than 10 times greater than regular activated carbon, allowing it to rapidly absorb and remove chlorine, rust, heavy metals, organic compounds, and odor-causing substances commonly found in tap water.

Thanks to its fast absorption rate, excellent reusability, and eco-friendly properties, ACF filters are widely used in medical, industrial, and beauty applications.

🌀 Key Functions of the ACF Filter

• Removes residual chlorine – Eliminates chlorine, a key irritant for the scalp
• Filters rust and heavy metals – Blocks contaminants from aging water pipes
• Absorbs harmful gases and odors – Keeps water clean and odor-free
• High surface area with fast reaction speed – Enables efficient and powerful purification

💆♀️ Why Water Quality Matters in K-HeadSpa

A head spa is a high-sensitivity treatment that directly targets the scalp and hair roots.
This makes the purity of the water that touches the scalp one of the most critical factors for treatment quality and client satisfaction.

• Clean water enhances product absorption, boosts treatment effectiveness, and minimizes irritation
• In contrast, impure water may cause scalp issues, such as itching, inflammation, or reduced efficacy of applied products

💡 The effectiveness of a head spa begins with filtered water.

🔄 When to Replace the ACF Filter

Because water quality varies depending on your region and plumbing conditions, it's most realistic and effective to replace the ACF filter based on the actual condition of the water—not just by time.

Environmental factors such as old pipes or local water treatment standards can greatly affect contamination levels.
Rather than following a fixed schedule, please monitor the following signs to determine the right time for replacement:

🔍 Signs it's time to replace your filter:

• The filter turns noticeably cloudy or brown

• Water flow becomes weaker

• Unusual odor or cloudy water appears

• Visible debris or buildup inside the filter
