The frequency of household water purifier filters replacement is affected by many factors, including water quality, household water consumption, filter element quality, and frequency of use of the water purifier. The following is a detailed introduction to the frequency of replacement of reverse osmosis filter elements.
Main influencing factors
1.Water quality:
If the local water quality is poor and contains more impurities and pollutants, the filtration burden on the filter element will increase, thus shortening the service life of the filter element.
On the contrary, if the water quality is good, the frequency of filter replacement may be relatively low.
2.Household water consumption:
The greater the household water consumption, the greater the filtration capacity of the filter element, and the wear rate of the filter element will be accelerated, so the filter element needs to be replaced more frequently.
For example, when a family of four uses about 20 liters of water per day, the replacement cycle of the RO reverse osmosis membrane filter element may be about 2 years; if the water consumption increases to 30 liters per day, the replacement cycle may be shortened to about 1.5 years.
3.Filter quality:
High-quality filter elements have good filtration effect, long service life, and relatively low replacement frequency.
Conversely, a lower-quality filter may become clogged or damaged more easily, requiring more frequent replacement.
4.Water purifierusage frequency:
If the water purifier is used more frequently, the filter element will wear out faster.
For example, some families use water purifiers extensively every day, and the filter elements may need to be replaced more frequently.
Specific replacement cycle
1.PP filter element:
As the first-stage filter element, PP cotton mainly filters large particles in the water, such as rust, sediment, colloids, algae, etc.
The replacement cycle of the PP cotton filter element is 3 to 6 months. In some areas with good water quality, the PP cotton filter element can be used for 6 to 12 months.
2.Activated carbon filter element:
It mainly adsorbs gas pollution such as residual chlorine and chemical residual gases.
The replacement cycle is generally 6 to 12 months.
3.RO membrane filter element:
The core filter element of the reverse osmosis water purifier can filter out bacteria, viruses, heavy metal ions and other tiny impurities in the water with extremely high filtration accuracy.
The replacement cycle is generally 2 to 3 years, but it may be shortened to about 1.5 years or extended to 3 to 5 years due to factors such as water quality and usage.
4.Post activated carbon filter element (taste factor filter element):
The main function is to improve the taste of water and inhibit bacterial regeneration.
The replacement cycle is relatively long, generally about 1 year.
Suggestions
In order to ensure the filtration effect of the water purifier and the safety of drinking water for your family, it is recommended to reasonably determine the replacement cycle of the reverse osmosis filter element based on factors such as local water quality, household water consumption, filter element quality, and frequency of use of the water purifier. At the same time, check and clean the water purifier regularly to keep it in good working condition. If the filter element is found to be clogged or the filtering effect is reduced, the filter element should be replaced in time. Also, refer to the device's instruction manual and follow the manufacturer's recommendations.
