In recent years, with the increasing concern about food safety and water safety, more and more people are paying attention to and installing water purifiers. How can we choose a suitable water purifier in the face of a dazzling array of water purifiers on the market? What are the things you need to pay attention to during installation and use?
Types and advantages and disadvantages of water purifiers
At present, there are two major types of water purifiers on the market. One is a filter-type water purifier. The water purifier adopts a filter core structure. According to different needs, it can be matched with different filter elements. The advantage is that the price is relatively cheap. The filtering accuracy is relatively high. The disadvantage is that the life of the filter element is relatively short. For example, the life of PP cotton is 3-5 months, the life of activated carbon is about half a year, the life of ultrafiltration is 1-2 years, and the water output is small, which is only suitable for drinking.
There is also a water purifier that uses RO reverse osmosis technology, commonly known as pure water machine. This kind of, first appeared in the aviation industry, was developed for the aviation personnel to solve drinking water. The advantage is that the water discharge precision is high. Except for water molecules, any substance can't get through. The disadvantage is that the purified water is too pure and lacks beneficial to the human body. Trace elements, on average, a cup of pure water, to produce 3 cups of wastewater, and must use electricity.
In addition, there are ion water machines, magnetized water machines, water machines, etc. For people with special needs, such as ion water machines, water can be electrolyzed into two kinds of water, acid and alkali. Alkaline water is used for drinking, and acidic water is used for bathing. It has a certain effect on common skin diseases.
Consider your own water quality when purchasing
The first step in selecting a water purifier is to choose according to the water quality of the home. For the water quality in the north, it contains more calcium and magnesium ions and is prone to scaling. It is recommended to choose a water softener that can effectively reduce the hardness of the water. Urban tap water contains more chlorine and heavier odors. Urban residents can purchase household water purifiers with more activated carbon load. Because activated carbon has a strong adsorption effect on residual chlorine and heterochromatic odor in water, it has obvious removal effect.
For tap water with a turbid water quality, a household water purifier with dual functions of coarse filtration and fine filtration should be purchased. For areas with serious water pollution, a reverse osmosis pure water machine can be purchased to completely remove impurities from the water.
Secondly, it is best to choose a water purifier brand with NSF certification when purchasing. NSF is the designated collaboration center for the World Health Organization (WHO) on food safety and drinking water safety and treatment. Products that have passed NSF testing and meet NSF standards are authorized to use the NSF logo, so any product licensed to have the NSF logo means that the product is a confirmed good product.
Installed under the preferred kitchen sink
The preferred installation location should be in the cabinet under the kitchen sink or under the sink. The wall mount can be installed in a normal life and is not easy to touch. Secondly, try not to install outdoors, the winter in the north is cold, and the temperature is too low, which makes it difficult to make water in the drinking fountain. In addition, it is best not to install the water purifier close to the heat source or direct sunlight to the position, because most of the filter shells are made of plastic, close to the heat source, easy to disintegrate the plastic, resulting in odor and secondary pollution.
