I like the brand Yue Breathe very much, so I will know it. Among the indoor purification brands, Yue Breathing has a great advantage, because his family independently develops, produces and establishes a Yue Breathing strain bank, has a billion-level high-density Bacillus fermentation technology, and independently produces products in Bacillus fermentation.100000 clean workshop products can be filled, and related patents and factory pictures can be seen in the live broadcast room. He has been using his probiotic full purifier at home, and the sterilization effect is very good.
