Activated Carbon Fiber (ACF) is a carbon-containing fiber produced through processes like carbonization and activation. It features nano-scale pores and a unique adsorption structure. Its large surface area and narrow pore distribution allow for quick adsorption and desorption and a high adsorption capacity. ACF is widely used in environmental protection, catalysis, medicine, military, and pollutant purification.
ACF VS traditional activated carbon
Traditional activated carbon is made from high-quality anthracite, sawdust, or nutshells, processed through activation and other production methods into a porous adsorbent material, typically in pellets, powder, or granules. However, ACF has a fibrous structure filled with well-developed micro-pores. In water purification, ACF is 5-6 times more effective than traditional activated carbon and has an adsorption rate of 100-1000 times faster.
ACF has a finer diameter, larger surface area, more developed internal micro-pore structure, and a narrower and more uniform pore size distribution than activated carbon. This gives it a higher adsorption capacity and faster adsorption dynamics.
Due to its superior effectiveness and more complex production process, ACF is significantly more expensive than traditional activated carbon, costing several to even dozens of times more.
ACF VS KDF55
Many shower filters use KDF55, an outdated water purification technology. ACF offers better filtration, has a longer lifespan, and costs slightly more.
KDF shower filters only remove chlorine and typically last 3 to 6 months. In contrast, ACF filters effectively remove chlorine, THMs, organic pollutants, and other harmful substances for 9 to 12 months.
However, increased cost and longer lifespan of ACF shower filters can reduce a company's profit margins. Although ACF provides better purification, most companies still rely on the outdated KDF55 to filter shower water.
Pre-filter for Shower Water Softening System
From the comparison above, it's clear that activated carbon fiber (ACF) is the most suitable pre-filter for a shower water softener. Our shower softening system uses ACF instead of KDF55 to ensure optimal water purification. This choice reflects our commitment to delivering the best possible experience for our customers.
