Background technique

The concept of water filtration is defined in terms of the host and guest location of the water. When water is the main body, water filtration is a medium for filtering and processing other impurities, and it is a filtering method that effectively separates solids and gases by dissolving water. When water is used as the object, water filtration is a method of special treatment for water. It is a method of removing suspended solids in water by using a filter medium to obtain clean water. Water filtration vacuum cleaners use water as a filter medium to remove dust, garbage and bacteria. When various microorganisms are sucked through the water tank by strong suction, most of them are dissolved and locked in the water. Wet the dust with water to avoid the overflow of fine dust during vacuuming; purify the inhaled gas through water to dissolve microorganisms such as allergens and bacteria. Then, it is further filtered through HEPA, high-efficiency filter cotton, etc., through these three purification systems to ensure the perfect and efficient water filtration.
