Comprehensive Guide to Replacing Water Filter Cartridges in a 4-Stage Water Filtration System

Today, we completed a water filter cartridge replacement service for a customer. This filtration system features 4 stages of filtration, each designed to provide clean, safe, and great-tasting water. For this service, we replaced three filter cartridges. The fourth filter, the UF Membrane Ultra-Filtration Cartridge, was not replaced as it remains functional and efficient.

Filter Cartridges Replaced and Their Functions

1. PP Sediment Filter

Function: Removes large particles such as sand, rust, and sediment, protecting downstream filters.

2. UDF GAC Carbon Filter

Function: Uses granular activated carbon to absorb chlorine, odors, and organic compounds, improving water quality.

3. CTO Carbon Filter

Function: Refines water further by removing residual odors and organic impurities, enhancing taste (installed as the fourth stage).

UF Membrane Ultra-Filtration Filter: Positioned in the third stage, this filter removes bacteria and fine particles with a precision of 0.01 microns. It was not replaced today, as its performance remains optimal.

4层过滤净水器滤芯更换流程详解

今天我们为一位客户进行了净水器滤芯更换服务。这是一台具备4层过滤系统的净水器，为确保过滤效果，定期更换滤芯至关重要。此次更换涉及三支滤芯，第四支滤芯 UF Membrane 超滤膜滤芯 今天未更换，因为其过滤效果仍在正常范围内。

更换的滤芯型号及功能

本次更换的滤芯包括：

PP Sediment 滤芯：主要去除大颗粒杂质，例如泥沙、铁锈等。
UDF GAC Carbon 滤芯：采用活性炭吸附异味、余氯和有机化合物，改善水质。
CTO Carbon 滤芯：进一步去除水中的异味、残余有机物，提升水的口感（放置在第四道）。

UF Membrane 超滤膜滤芯（过滤精度0.01微米）作为第三层，主要用于拦截水中的细菌和微粒，确保最终的水质安全。由于其性能正常，今天未进行更换。

Step-by-Step Cartridge Replacement Process

1. Handling the UDF GAC Carbon Filter

Replacing the UDF GAC Carbon Filter requires special attention to flush the activated carbon:

Why?: Flushing removes carbon fines, preventing them from clogging subsequent filters like the UF Membrane.
How?: After installation, run water through the filter until it flows clear, ensuring no residual particles.

详细更换步骤

1. 更换活性炭滤芯 (UDF GAC Carbon)

在更换 UDF GAC Carbon 滤芯时，特别注意活性炭水的排放：

原因：防止细小活性炭颗粒流入后续滤芯（如 UF Membrane 超滤膜），可能导致阻塞。
操作：安装新滤芯后，打开水龙头，排放活性炭水，直到水清澈无杂质为止。

2. Replacing PP Sediment and CTO Carbon Filters

Replace filters in sequence according to their designated positions.
PP Sediment Filter is always installed as the first stage to capture large contaminants.
CTO Carbon Filter is installed as the fourth stage to finalize purification and enhance taste.

2. 更换 PP Sediment 和 CTO Carbon 滤芯

按照滤芯的正确安装顺序更换：

PP Sediment 滤芯作为第一道，过滤大颗粒杂质，保护后续滤芯。
CTO Carbon 滤芯作为第四道，提供最后的净化，提升水质的口感。

3. Flushing the System

Open the water source and flush all new cartridges for at least 10 minutes to eliminate any residual debris or contaminants.
Inspect water quality to ensure there are no odors or discoloration.

3. 冲洗新滤芯

打开水源冲洗新滤芯，至少10分钟，以排除滤芯内残余杂质。
检查水质，确认无异味或颜色异常。

4. Cleaning and Leak Inspection

Use a dryer to remove moisture from the filter housing and seams, preventing rust and ensuring a snug fit.
Carefully check all connections for leaks before finalizing the process.

The UF Membrane Ultra-Filtration Filter

The UF Membrane Filter, which offers precision filtration of up to 0.01 microns, was not replaced during this service. However, regular checks (every 6–12 months) are recommended to ensure consistent performance.

Why Timely Cartridge Replacement is Crucial

Ensures consistently clean, safe drinking water.
Prevents clogging and extends the lifespan of the filtration system.
Maintains optimal water flow and filtration efficiency.

4. 清洁及漏水检测

使用吹风机将壳体及缝隙中的水吹干，防止后续使用中因残水导致生锈或漏水问题。
仔细检查每个接缝处，确保无漏水现象。

未更换的 UF Membrane 滤芯

由于UF Membrane 超滤膜滤芯的过滤能力保持正常，此次并未更换。但需定期监测其性能，确保高效运行。通常建议每6至12个月检查一次，根据实际使用情况决定是否更换。

滤芯更换的必要性

及时更换滤芯不仅能确保净水器的正常运行，还能带来以下好处：

保证水质的清洁与安全，避免二次污染。
延长设备使用寿命，减少维修成本。
保持正常水流速度，不影响日常使用。
