Pipeline machine is a pipeline drinking machine, which has no filtering function, only plays the role of boiling water and making ice water, which is equivalent to the traditional drinking machine and needs to be combined with water purification equipment.

The direct drinking machine has its own filtering function, and the filtered water quality can achieve the effect of direct drinking. Pipeline drinking machines can be divided into ultrafiltration drinking machines (purified water) and reverse osmosis drinking machines (purified water) according to the effluent quality. Most direct drinking machines integrate filtering, boiling water and making ice water, and are widely used in homes and offices. They are the most advanced direct drinking water equipment at present, and will gradually replace bottled water and traditional water dispensers.

Tips for purchasing direct drinking machines;

1. See if the direct drinking machine has a hygiene license: the product name and model written on the approval should be consistent, because even if it is a certified enterprise, there are cases where one license is used for multiple purposes, that is, multiple product models use one hygiene license approval, and consumers must check it clearly.

2. See if the filter element of the direct drinking machine is suitable: the first generation direct drinking machine mainly filters through activated carbon and ceramics. It is easy to breed bacteria, pollute water sources and fail to achieve the effect of cleaning water sources; The second generation direct drinking machine adopts various artificial polymer membrane filtration, which has obvious effect on removing harmful substances in water, but its fatal defect is that it filters out trace elements beneficial to the body.

The third-generation direct drinking machine adopts nano-microcrystalline filter core technology, which solves the defects of the second-generation direct drinking machine and filters out harmful substances and heavy metals in water.
