We can't avoid business trips in our life. The water purifier will not work during this period. If you travel for 3-5 days in a short time, you may find that the water in the water purifier may have a peculiar smell. This is because the purified water is stored in the pipeline or the water tank has deteriorated. You can replace the water in the original pipeline and the water in the water tank through the flushing function of the water purifier, and flush the pipeline at the same time. The same waterproof can eliminate the peculiar smell. If you travel for ten and a half days or even longer, you need to replace the filter element. Because you haven't used it for a long time, the filter element in the water purifier is dehydrated and hard, and it can't absorb water and filter again. You need to replace the filter element to achieve the effect of normal use.
