How to choose a faucet with purification function suitable for different water quality conditions?

Choosing a faucet with purification function suitable for different water quality conditions requires comprehensive consideration of water quality characteristics, technical parameters of the faucet, functional requirements, brand reputation and other factors. The following are specific selection points:
Understand water quality
Test water quality: You can use professional water quality testing tools or send water samples to professional testing institutions to test water quality hardness, pH, heavy metal content, impurity content, microbial content and other indicators. You can also consult the local water supply department to find out the general situation of local water quality.
Determining water quality problems
Hardness: According to the test results, if the water quality hardness is high, the content of calcium and magnesium ions in the water is high, and it is easy to scale, it is necessary to choose a faucet with scale removal function.

Ph: Acidic water quality may be corrosive, requiring the faucet to have good corrosion resistance; Alkaline water quality may lead to material precipitation, and it is necessary to consider the anti-scaling ability of the faucet.
Impurities and microorganisms: If there are many impurities and microorganisms in the water quality, the faucet needs to have a strong filtration capacity to effectively intercept and remove these pollutants.
Pay attention to faucet technical parameters
Filtration accuracy: According to the size and type of impurities in the water quality to select the appropriate filtration accuracy of the faucet. If the water quality contains more sediment, rust and other large particle impurities, you can choose a faucet with a filtration accuracy of about 5 microns, which can effectively intercept these impurities; If there are bacteria, viruses and other microorganisms in the water, it is necessary to choose a faucet with a filtration accuracy of 0.1 micron or even higher.
Filter material
PP cotton filter: the price is low, the filtration accuracy is generally 1-5 microns, mainly used to filter large particles of impurities, such as sediment, rust, etc., suitable for good water quality, only simple filtration.
Activated carbon filter element: has good adsorption performance, can remove the residual chlorine, odor and part of the organic matter in the water, has a good effect on improving the taste of the water, suitable for areas with high residual chlorine content in the water.
RO reverse osmosis filter element: high filtration accuracy, can remove almost all impurities in water, including heavy metal ions, bacteria, viruses, etc., can be used in poor water quality, high hardness or heavy metal pollution areas.
Water flow: According to the household water consumption to choose the appropriate water flow of the faucet. Generally speaking, the water flow rate of the faucet used by the family is more suitable in 1-3 liters/minute, which can meet the water needs of daily washing vegetables, washing rice, washing and so on. If the family population is large or the water demand is large, you can choose a tap with a larger water flow.
Consider functional requirements
Descaling function: For water with high hardness, you can choose a faucet with an ion exchange resin filter or electromagnetic descaling function, which can remove calcium and magnesium ions from the water through ion exchange or electromagnetic action to prevent scale formation.
Bactericidal function: When the microbial content in the water is high, you can choose a faucet with bactericidal function, such as products with ultraviolet sterilization, electrolytic water sterilization or silver ion sterilization function, which can effectively kill bacteria and viruses in the water and ensure water safety.
Adjusting water quality function: For acidic or alkaline water quality, you can choose a faucet with the function of adjusting the pH value of the water quality, by adding alkaline or acidic substances, the water quality is adjusted to nearly neutral, so that the water quality is more suitable for use.
