The filtration function of plastic desktop water dispensers plays a vital role in ensuring water safety. Impurities and harmful substances in water, such as suspended particles, chlorine, heavy metals, bacteria and viruses, may pose a potential threat to health, so the effect of the filtration system directly affects the quality of drinking water. Many desktop water dispensers are designed to include multiple filtration levels to ensure that the water quality is purified to varying degrees, thereby greatly improving the safety of drinking water.
For example, the common activated carbon filtration system can effectively remove chlorine, odor, some organic pollutants and certain heavy metal ions in water. The surface of activated carbon has a rich pore structure that can adsorb harmful substances in water, thereby improving water quality. In addition to activated carbon, some high-end water dispensers are also equipped with reverse osmosis (RO) technology, which is a more advanced filtration method that removes tiny particles such as dissolved salts, bacteria, and viruses from water through a semi-permeable membrane. The reverse osmosis system can provide extremely high purification effects and is suitable for home or commercial environments that require higher water quality standards.
Ceramic filters use their fine pores to filter bacteria and suspended particles in water, which are suitable for removing tiny physical impurities, but are relatively weak in removing chemicals. Therefore, many desktop water dispensers use a composite filtration system, which is a combination of multiple filtration methods, which can effectively remove a variety of pollutants in the water.
If the filter element or filter is not replaced for a long time, the filter material will gradually become saturated, lose the ability to absorb harmful substances, and may even become a breeding ground for bacteria, which will affect the water quality and cause counterproductive effects. Therefore, regular inspection and replacement of filters is the key to maintaining their filtration effect. Different brands and models of water dispensers may have different filter replacement cycles, and it is generally recommended to replace them every 6 months to 1 year.
Although many plastic desktop water dispensers are equipped with filtration functions, the filtration effects of different brands and models vary greatly. Some water dispensers can only remove large particles and some harmful chemicals, while some high-end products can provide comprehensive water purification, including the removal of bacteria, viruses and heavy metals in the water. Therefore, when purchasing, consumers need to choose a suitable filtration system according to their own needs. If the water source used is of poor quality, it will be more important to choose a desktop water dispenser with an efficient filtration system.
