One: Water Purifier and Its Purchase
A water purifier is a device designed to remove impurities from tap water, making it safer and more pleasant to drink. When purchasing a water purifier, there are several important factors to consider.
First, always choose well-known brands. Reputable manufacturers ensure quality and reliability. Second, the price of a water purifier should be proportional to its performance. Different models have varying structures and filtration capabilities. For example, multi-stage filtration systems offer better purification than single-stage ones. Among these, reverse osmosis (RO) purifiers are considered the most effective in removing contaminants like heavy metals, bacteria, and viruses.
Third, consider your local water quality. In regions with high water hardness, such as northern China or limestone areas in the south, water contains high levels of calcium and magnesium ions, which can cause scaling. In such cases, a water purifier equipped with ion exchange resin is recommended. In urban areas where water may contain chlorine, color, odor, or organic compounds, a purifier with a high activated carbon capacity would be ideal, as activated carbon effectively removes these impurities. For turbid or heavily polluted water, a dual-filtration system that combines coarse and fine filtration is essential. If you don't need to drink the water directly, an RO purifier is a good choice.
Two: Purchasing a Pure Water Machine
A pure water machine uses reverse osmosis technology to produce clean, purified water without adding any chemicals. These machines are typically divided into two types: household units for drinking water and laboratory-grade units for scientific use.
When buying a pure water machine, several factors should be taken into account. First, check the manufacturer's reputation and whether they have independent design and production capabilities. Next, evaluate the product’s quality. Price varies depending on the components used—high-end models often use imported parts and may cost between $2000 and $4000, while lower-cost options use domestic parts and are priced below $2000.
Consider the machine’s daily water output; it should be at least three times your daily consumption. The design and ease of use are also important—some models are difficult to install and maintain, while others are user-friendly. Look for a model with a stable structure and minimal maintenance requirements. Additionally, ensure the seller provides reliable after-sales service, as a pure water machine requires ongoing support and maintenance over time.
Three: Water Softener and Its Purchase
A water softener is a device that reduces water hardness by removing minerals like calcium and magnesium. It uses ion exchange technology to soften all the water in a home, preventing scale buildup in appliances and fixtures.
The benefits of using a soft water machine include extending the lifespan of water heating equipment, reducing energy consumption, and improving the appearance of bathroom surfaces. Soft water is also gentler on the skin, offering a more comfortable bathing experience.
When purchasing a water softener, avoid placing it near heat sources or in areas where hot water might come into contact with it. If the raw water does not meet municipal standards, a pre-treatment system should be installed before the softener. Ensure there is enough space between the drain pipe and the floor drain to prevent siphoning. After installation, adjust the valve to the backwash position and flush out the protective liquid from the resin. Regularly check the salt level in the tank, using only high-quality edible salt. Avoid salt with additives or impurities, and make sure to break up any salt bridges that may form. If the unit will not be used for a long time, turn off the water and power supply to prevent damage. Always ensure the inlet pressure is within the recommended range (0.2–0.5 MPa), and follow proper installation guidelines for electric control models.
