The more filters, the better. Some low-end water purification products often have four or five filter elements, but they all use simple filter materials, and the filtering effect may not be as strong as that of high-performance filter elements.
Bian Xiao suggested that disposable filter elements should be used for the last filtration of drinking water to avoid secondary pollution.
Two: only look at the brand, regardless of professionalism.
Many well-known brands belong to enterprises dealing in various household appliances. Their goal is to meet the ordinary life needs of the low-end market, and they can only produce low-end ordinary water purification equipment.
The complexity of domestic water purification, especially direct drinking water, requires a professional research and development team. Therefore, try to choose the brand of water purification equipment made by professional water purification enterprises, which will not only ensure the technical quality, but also give you more professional services.
Three: activated carbon filtration technology is outdated.
No, activated carbon is the best filtration and adsorption material in nature.
Almost all water purifiers use activated carbon.
If activated carbon is not used, no matter how high the filtration accuracy is, the taste of the effluent will be discounted.
There are three kinds of activated carbon: granular, powdery and activated carbon rods. The first two are low in cost, but the filtration is often incomplete. The latter is a safer choice, which can achieve 100% complete filtering.
Four: the filter element cannot be replaced for a long time.
In fact, the filter element that will block is a good filter element, which also shows that the water purifier is really effective.
It is often exaggerated to claim that the filter element will not be changed for 3~5 years in the market.
Don't go after the cheap ones too much.
Water purifier is still the demand of people who pursue high-end quality of life in China. Generally speaking, the higher the price, the better the effect.
In addition, the life of high-quality filter elements and the amount of clean water will be better, and the price will naturally go up.
But overall, it is still cost-effective.
