The external filter box introduced by BESSN is designed with the core concept of "high-end quiet and elegant, stable purification. The whole body adopts a round outline, with a deep black appearance and exquisite rose gold decorative ring, presenting a modern and advanced visual texture, which can naturally integrate into a variety of home atmosphere and reflect the high-end positioning of the product.

In terms of structure and function, the filter box adopts the optimized water flow path and anti-blocking structure design. Deflector flip structure, change filter cotton more convenient. Double overflow holes are added to the box body to ensure that users can use it at ease. The convex three-dimensional structure set at the bottom of the box body further expands the water flow channel space, keeps the water flow circulating smoothly inside the box body, is not easy to generate water accumulation area, and improves the overall filtration efficiency and stability. The bottom double-turn water design, put an end to dead water, while ensuring that the maximum flow through the germicidal lamp. The anti-blocking comb and porous structure is designed in the filter material area, which can effectively block the bulk filter material from entering the water outlet and avoid blockage caused by the accumulation of filter material. And through reasonable aperture and distribution, the water diversion efficiency is improved.

In terms of layering of filter materials, the concept of "partition purification" is followed. Cashmere cotton, biochemical cotton and filter materials are usually arranged in sections to purify the water flow layer by layer. The whole equipment adopts ABS durable material, the texture is improved, the strength is also greatly improved, and the structural stability and safety in long-term use are ensured.

It is provided with a visual small window for the working state of the sterilization lamp, so that the user can intuitively understand the operation situation.

Overall, the filter box is unified in appearance, structure and experience; it is a high-quality external filtering solution with both color value and performance.
