The flushing and maintenance of the folding filter element is a key step to ensure its long-term efficient operation. The following are detailed steps and precautions for washing and maintaining folding filter cartridges, compiled from multiple authoritative sources:

Rinse steps

Prepare to flush the water source:

Separate the connection between the filter element and the water purifier or other equipment, and remove the filter element.

Preliminary flushing:

Rinse the outer surface of the filter element thoroughly with tap water to remove any dirt and impurities from the surface. Be careful not to forcefully impact the filter element to prevent damage.

Soak and clean:

For filter cartridges that require deep cleaning, appropriate cleaning solution (such as warm water, diluted neutral cleaner, or vinegar solution) can be used to soak the filter cartridges. The soaking time depends on the material of the filter element and the degree of contamination, usually 10-30 minutes.

Vinegar or diluted acid solution can effectively remove calcium and other scale on the surface of the filter element, and kill bacteria.

Rinse again:

After soaking, rinse the outer surface of the filter element thoroughly with tap water again to ensure that the cleaning solution is completely rinsed clean.

Drying treatment:

Place the filter element in a ventilated and dry place to air dry, ensuring there is no residual moisture before reinstalling it for use.

Special maintenance:

For filter cartridges with a filtration pressure difference greater than 0.2 Mpa or a significant decrease in flow rate, special maintenance treatment may be required, such as flushing the outer wall of the filter cartridge with low-pressure water flow or blowing the filter cartridge back with dust-free high-pressure air.

Long term storage:

If the folding filter is not in use temporarily, it should be stored in a clean and dry place to avoid moisture and mold. If long-term storage is required, it can be soaked in water containing antibacterial agents (such as less than 10ppm sodium hypochlorite or 2% hydrogen peroxide solution) and rinsed clean before reuse.

Above all, the flushing and maintenance of the folding filter element is a meticulous and important process that requires following the correct steps and precautions to ensure efficient operation and extended service life of the filter element.
