Many families have this question: If the tap water at home has clearly been treated by the water plant, why do they still need to install a water purifier?

In fact, although tap water meets drinking standards when it leaves the water plant, it is prone to secondary contamination after long pipeline transport and secondary supply in communities. Choosing the right water purifier is a necessary measure to protect the health of the whole family, and the key is to choose the right filter cartridge — ceramic membranes are the best choice for household drinking water.

Tap water seems clean, but these hidden risks should not be ignored

The tap water we drink every day appears clear, but in fact hides various potential risks. Installing a household water purifier is especially crucial for families with elderly people and children.

（一）Pipeline and Secondary Water Supply Pollution

Tap water is delivered through municipal pipelines and community network pipelines. In old communities, galvanized pipes are prone to rust and bacterial growth; if the secondary water supply tank is not properly cleaned, it can also breed algae and bacteria, resulting in tap water having an unusual taste and impurities.

（二）Harmful substances hidden in water

Tap water may contain trace amounts of heavy metals (such as manganese and lead), residual chlorine, microplastics, etc. Long-term consumption can affect health; for example, excessive manganese can impact children's intellectual development.

（三）Adapt to diverse household needs

A water purifier can meet all daily water needs such as drinking, preparing formula, washing vegetables, and cooking soup, fully ensuring drinking water health.

A household water purifier is not an 'IQ tax,' but a necessary measure to address potential drinking water risks, and the choice of filter cartridge directly determines the purification effect and healthiness.

Reject excessive purification; ultrafiltration membranes are the preferred choice for household drinking water

The mainstream filter cartridges on the market are divided into reverse osmosis membranes and ultrafiltration membranes. Many people follow the trend and choose reverse osmosis, but for most households, ultrafiltration membranes are more suitable for long-term drinking. The key is 'scientific purification, without blindly pursuing extreme purity'.

Reverse osmosis membranes have extremely small filtration pores and can remove all substances in water, including beneficial calcium and magnesium minerals. Long-term consumption of this 'ultrapure water' can easily lead to malnutrition. Refer to the Chinese edition of the international top journal Environmental Science & Technology (ES&T), where the editor explicitly warns: 'Water that is too pure' may cause malnutrition in the human body and even increase the risk of disease.

Related studies also show that low-mineral water can increase cardiovascular-related risks in children; moreover, it requires electricity for water storage, produces a large amount of wastewater, and has poor adaptability.

The core advantage of ultrafiltration membranes is 'precise purification, scientific retention,' perfectly meeting household needs:

（一）Filter out hazards

The pore size is controlled between 0.1-1 micrometer, effectively capturing bacteria, viruses, heavy metals, and other harmful substances, addressing the problem of secondary pollution.

（二）Preserve nutrition

Do not filter out beneficial minerals such as calcium and magnesium, as these are convenient sources of nutrition for the human body. According to a survey of 11 islands in Japan shown in the figure, under the same diet and social background, the higher the natural hardness of drinking water, the greater the number of centenarians, with a correlation coefficient of 0.84 (p<0.01). This study has been published in the 2023 issue of Nutrients.

（三）Convenient and practical

No need for electricity to store water, fast water output, no wastewater, energy-saving and environmentally friendly, suitable for various household water use scenarios.

Both are ultrafiltration membranes, so why is the ceramic one more worth choosing?

The ultrafiltration membranes on the market are mainly organic membranes and ceramic membranes. As a high-end option, ceramic membranes far surpass ordinary organic membranes in terms of health and durability, making them more suitable for long-term use at home.

（一）Safer

Made of inorganic materials (alumina, zirconia), with no organic plastic components, it does not release plasticizers or microplastics, preventing secondary pollution from the source.

（二）More durable

The surface is smooth and not easily clogged, and the filtration effect can be restored after rinsing; the service life can reach more than 20 years, much longer than ordinary organic membranes, saving more money and worry.

（三）Filter stability

The aperture is uniform and the structure is stable, unaffected by water pressure or water quality fluctuations, ensuring consistently high water output quality.
