In modern society, water quality is increasingly concerned. With the advancement of industrialization and the intensification of environmental pollution, the water source in daily life is no longer as pure as in the past. In order to ensure the safety of household water, water purifiers have gradually become one of the essential household appliances. In the water purifier, the filter element is undoubtedly one of the core components, which is directly related to the purification effect of water quality and the health of family members. So, what are the functions, types, materials, prices, filtration accuracy and replacement frequency of the water purifier filter element? These aspects will be detailed below to help consumers better choose the water purifier filter that suits their needs.

First, the role of the water purifier filter element

The main function of the filter element is to filter harmful substances in the water, such as sediment, rust, bacteria, viruses, heavy metals and so on. It removes or reduces impurities in the water through physical, chemical or biological means, so that the water quality meets the drinking standard. Different filters play different roles in the process of purifying water quality:

1. Primary filtration:

Remove large particles of impurities in the water, such as sediment, rust, etc.

2. Intermediate filtration:

Filter suspended substances, colloids and some bacteria in the water.

3. Advanced filtration:

deep filtration of small particles, viruses, heavy metals, odors, etc.

The function of the filter element of the water purifier is not only to provide clean drinking water, but also to improve the taste of the water and make the water more sweet and delicious.

Second, the type of water purifier filter element

The common water purifier filter element on the market mainly has the following types:

1. PP cotton filter:

PP cotton filter is the most common primary filter material in the water purifier, which is made of non-woven fabric, mainly used to filter sediment, rust, large particle impurities in the water. The PP cotton filter element is usually located at the first stage of the water purifier to protect the subsequent filter element from being blocked by large particles. The price is usually between 10 yuan and 50 yuan, which is an economical primary filter element.

2. Activated carbon filter:

activated carbon filter is divided into granular activated carbon and compressed activated carbon filter, which is mainly used to remove residual chlorine, organic matter, odor and pigment in water. Activated carbon filter can not only absorb chemical pollutants in water, but also improve the taste of water. The price of granular activated carbon filter is generally between 50 yuan and 150 yuan, and the price of compressed activated carbon filter is slightly higher, about 100 yuan to 200 yuan.

3. RO reverse osmosis membrane filter element:

RO reverse osmosis membrane filter element is the most sophisticated filter element in the current water purifier, using reverse osmosis technology, which can filter out heavy metals, bacteria, viruses and other small pollutants in the water, and the filtration accuracy can reach 0.0001 micron. RO membrane filter element is usually used in the core part of the water purifier, which can effectively ensure the safety of drinking water. Due to the high technical content, the price of RO reverse osmosis membrane filter is more expensive.

4. Ultrafiltration membrane filter element:

The filtration accuracy of ultrafiltration membrane filter element is between 0.01 micron and 0.1 micron, which can remove small pollutants such as bacteria and viruses in the water, but retain mineral elements that are beneficial to the human body. Ultrafiltration membrane filter element is suitable for areas with good water quality, and can be directly drunk after filtration. The price of ultrafiltration membrane filter element is between 150 yuan and 300 yuan, and the price is moderate and suitable for family use.

5. Ceramic filter element:

Ceramic filter element filters bacteria, parasites and suspended matter in water through microporous structure, and its filtration accuracy is as high as 0.1 micron. The advantage of ceramic filter is that it can be repeatedly cleaned and used, but the disadvantage is that the service life is relatively short.

6. KDF filter element:

KDF filter element is a filter element made of copper zinc alloy, mainly used to remove heavy metals, chlorine and other chemicals in water, while having antibacterial effect. KDF filters are often used in combination with other filters to enhance the water purification effect. The price of KDF filter element is relatively high, suitable for consumers who pursue high-quality water purification effect.

Third, the filtration accuracy of the water purifier filter element

The filtration accuracy of the filter element of the water purifier is an important index to measure its purification effect. The filtration accuracy of different filter elements is as follows:

1. PP cotton filter element:

The filtration accuracy is about 5 microns, mainly used to remove large particles of impurities.

2. Activated carbon filter element:

The filtration accuracy is between 0.5 microns and 10 microns, mainly used for absorbing chemicals and odors in water.

3. RO reverse osmosis membrane filter element:

the filtration accuracy can reach 0.0001 micron, which can remove heavy metals, bacteria and viruses in water.

4. Ultrafiltration membrane filter element:

The filtration accuracy is between 0.01 micron and 0.1 micron, which can filter bacteria and viruses, but retain minerals.

5. Ceramic filter element:

The filtration accuracy is 0.1 micron, mainly used to remove bacteria and parasites.

6. KDF filter element:

The filtration accuracy is about 1 micron, mainly used to remove heavy metals and chlorine.

Fourth, the replacement frequency of the water purifier filter element

The replacement frequency of the filter element of the water purifier varies according to the type of filter element and the use environment. In general:

1. PP cotton filter element:

It is recommended to replace it every 3 to 6 months to ensure the filtration effect.

2. Activated carbon filter:

granular activated carbon filter is recommended to be replaced every 6 to 12 months, and compressed activated carbon filter is recommended to be replaced every 12 months.
