What do consumers need to pay attention to when choosing water purification faucet products?

Technical performance
Filtration technology: Understand the filtration technology used in the product, such as activated carbon adsorption, ultrafiltration, reverse osmosis, etc. Activated carbon can remove residual chlorine and odor; Ultrafiltration can filter bacteria, colloids, etc., but the removal effect of heavy metals and small molecules is limited. Reverse osmosis can remove almost all impurities, including heavy metals, salts, etc., which can be selected according to water quality and needs.
Filtration accuracy: This determines the amount of impurities that the faucet can intercept. The smaller the value, the higher the accuracy, such as 0.1 micron than 1 micron can intercept smaller particles, can choose the appropriate accuracy according to the impurities in the water, in general, want to remove bacteria and other microorganisms, need to choose 0.1 micron and below the accuracy of the product.
Filter life: View the estimated service life and replacement cycle of the filter. The filter element of some products has a long life, which can reduce the frequency of replacement, reduce the cost of use, and consider the convenience and cost of replacing the filter element.

Material technology
Main material: common copper, stainless steel, plastic and so on. The copper material is durable and corrosion-resistant, but there may be lead precipitation problems, so it is necessary to choose lead-free copper products with quality assurance. Stainless steel material high strength, not easy to rust; Plastic material is lightweight and low price, but make sure it is food grade plastic, safe and non-toxic.
Filter material: High quality filter material is the key to ensure the filtration effect. Such as activated carbon to choose strong adsorption of coconut shell activated carbon; Ultrafiltration membrane should choose the material with good hydrophilicity and high flux; Reverse osmosis membrane to choose a high desalting rate, durable brand film.
Manufacturing process: Check the process details of the faucet, such as whether the surface is smooth, no burr, sand hole, whether the welding place is firm and uniform, the sealing and durability of the product with good process is better, which can reduce the occurrence of water leakage and other problems.
Function and use
Water flow: To meet the daily demand for water, generally 1-3 liters per minute is more appropriate, if the family population is large or the water demand is large, you can choose products with larger water flow to avoid small water flow.
Whether there are additional functions: such as some faucets with water quality monitoring function, can display the water quality in real time; Some have automatic flushing function, which can extend the service life of the filter element, and can choose whether these additional functions are needed according to personal needs and budget.
Installation method: Consider the structure and space of the sink at home, choose the appropriate installation method, common platform type, under the table type, wall mounted, etc., to ensure that the installation is convenient and does not affect the normal use of the sink.
