At present, the domestic water purifier market is relatively messy, with different brands and shapes, which is dazzling. Therefore, when consumers buy water purifier products, they should conduct a comprehensive analysis and comparison from many aspects such as product brand, technology, process, materials, and services. So, how to buy a household water purifier? Activated carbon filter manufacturers today have specially summarized six aspects that need to be considered, hoping to help consumers.

1. Water quality status

The water quality conditions in each place are different, for example, the water hardness in the northern part of China is higher, and the water quality in the south is relatively softer, but because of industrial pollution and other factors, the content of heavy metals and organic matter is high. Drinking water generally buy reverse osmosis water purifier, such as tap water quality is really good and very stable, you can choose ultrafiltration machine; for washing, tap water hardness is high, such as tap water made of groundwater in the north, water softener should be used.

2. According to consumer demand

After bathing and washing your face, even if you apply moisturizer, it is still dry and itchy; after washing your hair, your hair becomes astringent and difficult to comb; when you brush your teeth and rinse your mouth, there is an indescribable strange smell when you drink water in your mouth; after washing your clothes, they are always hard and hard... If you have such troubles, you buy a water softener.

At present, the water softener basically uses ionic resin exchange technology to replace calcium and magnesium ions (water alkali) in the water with sodium ions to remove scale. The water softener is connected in series on the main pipe of the water meter, with a large water output, and is installed in the cabinet or bathroom, so that the water equipment (wall-mounted radiator, water heater, etc.) can be used without scaling and blockage, prolonging the service life, and saving energy and electricity; In addition, bathing and washing the face with softened water can make the skin smooth and delicate, and more protective for the skin of babies and children; clothes washed with softened water are whiter and fluffier, and the life of the clothes can be more than doubled; bathtubs, tableware, and tea sets washed with softened water are crystal clear and free of water stains.

If you want to remove harmful substances such as sediment, rust, organic matter, viruses, bacteria and heavy metals in the water, you can use it to meet the needs of family soup and rice, and the water purifier or ultrafiltration machine can meet your water needs.

3. Filter element function

The water purification principle of the water purifier is fully reflected in the efficiency of the filter element, and the filter element plays an important role in the overall efficacy of the water purifier. At present, most of the water purifiers sold on the market use activated carbon filtration, microporous ceramics, membrane separation filtration and other methods to purify water. According to the number of filter elements used, it is divided into coarse filtration, ultrafiltration water purifier, and RO reverse osmosis water purifier. Generally, PP fiber cotton, activated carbon, RO reverse osmosis membrane, UF ultrafiltration membrane, quartz sand, American KDF, ion exchange resin and other water treatment materials are used.

4. The functions of various filter elements

(1) Polypropylene spray filter element (PP): remove solid substances such as sediment, rust and algae in water; (2) Granular activated carbon filter element (UFD): remove residual chlorine, odor and solid impurities in water;(3) Compressed activated carbon filter element (CTO): further remove residual chlorine, odor and solid impurities in water;(4) RO reverse osmosis membrane: remove pollutants such as viruses, bacteria, organic matter, heavy metals and other pollutants in water;(5) Small T33 filter element: can better improve the taste of water; 4. Economic budget:

The purchase of a water purifier should not only consider the purchase cost of the water purifier itself, but also consider the use time and replacement cost of the filter element. If the family economic conditions are good, they will buy water purification products with beautiful appearance, exquisite materials and high degree of automation. There are enough economic conditions, and the water purifier, water purifier and water softener can all be installed and used in strings. In particular, we should remind that those inferior products with very low prices should not be bought, and it is better not to use them, which will cause serious consequences such as water leakage and flooding.

5. After-sales service

After many consumers buy some brands, they can't find the repair service phone or the address of the maintenance service company, which makes consumers very helpless and also causes a waste of resources, making the water purifier a furnishing. Since the current water purifier merchants basically cooperate with third-party water purifier after-sales service providers, the after-sales service is handed over to the third party to complete. Therefore, the after-sales service of our water purifier also depends on which service provider we cooperate with, whether the service is good or not, and whether the reputation is good. Water experts are the best at this.

6. Installation status

Kitchen: Use a kitchen reverse osmosis machine and ultrafiltration machine with membrane elements for drinking (drinking water, making tea, making coffee, including cooking rice, cooking porridge, stir-frying, cooking soup, decoction, etc.).

Bathroom: Choose a water purifier (KDF plus activated carbon) or a water softener for washing your face, bathing and laundry, because the water production is large enough.

Living room: Choose a single-heat or ice-hot vertical cabinet direct drinking machine, which is both convenient and stylish.

If it is a new house: drain the water pipes during the decoration, and if conditions permit, install the water purifier, bathroom water softener and the room wall-mounted pipeline machine together. Make a complete set of whole-house water purification solutions.

The more common water purifiers on the market are mostly physical filtration. People can choose one or several water purification products to combine into an overall water purification solution for drinking water and water use according to their own needs.
