The filter element is the soul of a water purifier, and it is essential to intercept impurities and harmful bacteria in water. It is necessary to regularly replace the filter element of a water purifier at home, otherwise impurities will adhere to the filter element for a long time, reducing the effectiveness of filtering impurities in water and even causing secondary pollution of water quality. This goes against the original intention of purchasing a water purifier to purify household water quality. Therefore, for the sake of family health, we must regularly replace the filter element.

So how often is the filter element of the water purifier replaced?

The replacement cycle of the filter element in a household water purifier is determined by the quality of the filter element, the filtered water quality, and the filtered water volume. Usually, people ask how long the filter can last? How much water can the filter element filter? This is actually asking about the lifespan of the filter element.

In fact, it is extremely imprecise to use how much time or water to indicate the lifespan of a filter element. The scientific expression method should refer to the amount of pollutants treated by the filter element. Once the filter element is put into use, its ability to handle pollutants begins to decline until its ability to handle pollutants disappears, which is when the filter element reaches its end of life. The process of using a filter element is a decrease in its ability to handle pollutants, which can also be considered as the consumption process of the filter element. It needs to be replaced over time.

In fact, when the filter element of the water purifier needs to be replaced, the water purifier will send some signals to remind you. If your water purifier has the following situations, it is reminding you to pay attention to replacing the filter element!

Signal 1: Water purification mechanism reduces water volume

Under the same conditions (such as the same water pressure and temperature), the water purification mechanism produces less water. So it is very likely that the filter element is blocked. If the filter element of the water purifier is approaching its service life, then a new filter element needs to be replaced for the water purifier.

Signal 2: RO reverse osmosis water purification mechanism water is too fast

When the water purifier shows a significant increase in water output, it is usually caused by damage to the RO membrane. In this case, we must replace the RO membrane with a new one, otherwise the water purifier will completely lose its filtration function, which will have adverse effects on the human body.

Signal 3: The taste of the water from the water purifier has deteriorated

This situation is due to the excessive impurities and bacteria filtered by the filter element of the water purifier, which accumulate at the filter element for too long, causing secondary pollution to the tap water. A lot of dirt stuck around the rim of the filter element, which also tells us that the filter element needs to be replaced.
