As water quality issues gradually gain attention, more and more families are starting to use filters to ensure the quality of daily drinking water. As a vital part of the water filtration system, household filters directly affect the purification effect of water quality. So, how often do household filters need to be replaced? This article will provide you with a detailed analysis of the replacement cycle of household filters and related precautions.
Household filters are mainly used to purify impurities, chlorine, heavy metals and harmful substances in tap water. It adsorbs or filters these harmful substances by physical or chemical means to ensure clean water quality and provide healthier drinking water. Depending on the filtering technology used, common household filters include activated carbon filters, RO reverse osmosis filters, ceramic filters, etc.
The replacement cycle of household filters is not fixed. It is mainly affected by the following factors:
If there is a need to frequently use the water purifier in the family, such as daily cooking, drinking water, washing, etc., the life of the filter may be shortened. High-frequency use means that the filter needs to be replaced more frequently.
The water quality varies greatly in different regions. If the water source in your area is seriously polluted and the impurities and minerals in the water are high, the service life of the filter will be greatly shortened and need to be replaced more frequently.
Different types of filter elements have different lifespans. For example, activated carbon filters generally need to be replaced every three to six months, while RO reverse osmosis filters may need to be replaced once a year. You can determine the replacement cycle based on the type of filter element used.
The larger the amount of water the filter handles, the heavier the burden on the filter element. Generally, the water flow of the filter will affect the life of the filter element, so the amount of water used in the home will also affect the replacement time of the filter element.
In addition to referring to the recommended replacement cycle of the filter element, you can also determine whether the household filter element needs to be replaced based on the following signs:
If the water flow of the water purifier slows down significantly, it may be because the filter element is blocked and cannot effectively pass the water flow, resulting in a decrease in the filtration effect.
If the filtered water has an odor or the water quality becomes turbid, this is also a common sign of filter element failure. Replacing the filter at this time can restore the cleanliness and taste of the water.
Some household filter cartridges may change the color of the water during use, especially when using activated carbon filter cartridges. If the water color becomes darker, the filter cartridge needs to be replaced in time.
Replacing household filter cartridges is not a complicated task, but in order to ensure the filtering effect, you need to follow the correct steps:
Before replacing the filter cartridge, you first need to turn off the power of the water purifier and make sure the water source is turned off.
According to the instructions of the water purifier, properly disassemble the old filter cartridge that has been used. Be careful not to damage other parts during disassembly.
Before installing a new filter cartridge, it is recommended to simply clean the water purifier to remove residual impurities inside.
When installing a new filter cartridge, you need to ensure that the filter cartridge is installed firmly to avoid water leakage.
After installation, reconnect the water source and power supply, and test the water flow and water quality to ensure that the filtering effect is as expected.
Regularly replacing household filters is an important measure to keep drinking water safe. By understanding the replacement cycle of the filter and the influencing factors, you can reasonably arrange the replacement time according to the actual situation to ensure that the water quality at home is always clean and healthy.
