5 precautions when purchasing a water purifier

Water purifier have become an indispensable home appliance product in home life, but many consumers feel a headache when faced with a dazzling array of water purifier products. There are still blind spots that consumers cannot reach in the process, materials and services of machine products, and the selection of unqualified water purifiers will bring drinking water safety problems to the family. Here are some practical tips for you to choose the correct water purifier products. suggestion:
First, how is the purification ability
The primary function of a water purifier is naturally to provide healthy and safe water. A simple method can be used to check the purification capacity of the water purifier:
Borrow a glass, fill the filtered water in a clear cup, and look carefully in a well-lit place for any fine particles suspended in the water. If there is, then the filtration effect of the water purifier is not good; if not, then cover the cup and let it stand for three hours, and then observe whether there is sediment at the bottom of the cup. If there is sediment at the bottom of the cup, it means that the suspended impurities in the water exceed the standard, and the filtration effect of the water purifier is unqualified.

Second, how does it taste?
In addition to looking at the water purification capacity, we also need to look at the taste of the purified water when purchasing a water purifier. There are many water purifiers on the market with good purification ability, but the purified water has lost the natural taste of the water itself.
Third, how to design
Whether the design of the water purifier is exquisite and fashionable can also reflect the manufacturer's processing ability and intention to a certain extent. We must learn to start from the details, identify the craftsmanship of the products, pay attention to details, such as product materials, gaps, filter elements, etc.
Fourth, after-sales service
Choosing a water purifier depends on the after-sales service. Some brands of water purifiers are only responsible for sales, not after-sales. It is very likely that after purchasing a water purifier, you cannot buy a spare filter element to replace the expired filter element, which will ultimately affect the purification effect of the product.
Fifth. Adapt to local water quality
The difference in water quality in various regions of my country is very large. Generally speaking, the water quality in the north is relatively hard and contains many impurities. Therefore, a water purifier or water softener with an ion exchange resin filter element should be purchased. The water quality in the south is relatively soft, and heavy metals and secondary pollution are serious. Families with high water quality requirements can choose a pure water machine. If the local water quality is better, an ultrafiltration machine can be selected.
