The water purifier with single outlet water is the outlet water from a faucet, so the outlet water is either purified water or purified water. The double outlet water purifier has two faucets, one for purified water and the other for purified water.

Single outlet water purifier, only one water mode can be selected, either pure water or purified water. If the water from the single outlet water purifier is pure water, it will not only need to plug in electricity but also discharge wastewater during the work process, which is relatively simple in daily use. The dual outlet water purifier can meet the two water purification needs, and its energy consumption is different. It can be flexibly switched according to its own needs and actual conditions.
