The invention discloses a manufacturing device of low-sodium healthy water. The device comprises a pretreatment device, an electro-adsorption device, a sodium filter or reverse osmosis device and a post-treatment device, and is characterized in that a water inlet of the electro-adsorption device and a water inlet of the sodium filter or reverse osmosis device are both connected to a water outlet of the pretreatment device; and a water outlet of the electro-adsorption device and a water outlet of the sodium filter or reverse osmosis device are together connected to a water inlet of the post-treatment device. The invention also discloses a manufacturing method of the low-sodium healthy water. By merging electro-adsorption water and water obtained after sodium filter or reverse osmosis, the merged water has advantages of the two kinds of water. Therefore, demand on low sodium is realized, and the requirement on water hardness and requirements of various trace elements can be met. The low-sodium healthy water is suitable for patients with hypertension and heart disease and also suitable for normal persons for long-term drinking.
