What's the difference between a straight drinking machine and a pure water machine?

Direct drinking machine is a tool to purify municipal tap water into direct drinking water, or to heat, refrigerate and distribute the purified water by consuming electric energy.

Water purifier is a kind of water purification equipment that uses multi-stage filter elements to purify water. Many physical methods such as filtration, adsorption and reverse osmosis are used for treatment, and no chemical agents are added. According to the water purification accuracy of water purifiers, they can be divided into household water purifiers and laboratory water purifiers.

Second, the advantages and disadvantages are different.

After the water of the direct drinking machine is purified by multiple stages (pay attention to the multi-stage purification, the filter element is the key, and it is generally necessary to know the replacement cycle of the filter element and the function of each filter element. ) It can effectively intercept substances harmful to human health, such as sediment, rust, suspended matter and macromolecular organic matter, and can effectively remove filtered residual chlorine and microorganisms. The filtration precision is high, and the purified water is close to mineral water, so it can be directly drunk raw.

The disadvantage is that it can't discharge sewage and its service life is short. The service life of PP cotton is 3-5 months, that of activated carbon is about 6 months, and that of ultrafiltration is about 1 year.

The water purifier takes RO reverse osmosis membrane as the core filter element, and the filtration accuracy is 0.000 1 micron. It can effectively remove the secondary pollutants in tap water caused by pipeline aging and water tank pollution, such as rust, colloid, organic matter, bacteria, viruses and other macromolecules, and only a small number of water molecules pass through the filter membrane, thus thoroughly purifying the water quality and truly achieving the pure effect.

The advantages of the water purifier are also disadvantages, because the filtration accuracy is too high, resulting in the lack of minerals needed by the human body in drinking water, which normal people can't drink.
