The filter screen can only filter physical properties, but it can't play the role of a water purifier.
The water filter mainly filters out most harmful substances in water through the principle of activated carbon and restores the essence of water source, but it can't be directly drunk in subtle places. Generally, the water filtered by the filter is used for industrial production or other commercial purposes.
Comparatively speaking, the water purifier is a relatively high-tech product. Internal filtering device combined with cutting-edge technology has more powerful filtering function. Some harmful microorganisms can even be filtered out, so this kind of water is generally drunk by people.
A water filter is a device for filtering water. The backwash industrial water filter is installed on the water supply pipeline of power station, chemical industry, printing and dyeing, paper making and other industries. The water filter is mainly suitable for pipes below Dg500mm, which can replace the secondary filter screen and save costs.

Extended data:
The correct way to use the water purifier is:
1. Open all tap water, tap water inlet ball valves and purification faucets, and rinse 15 minutes until the produced water is clear and foam-free. Frequent switching of tap water during flushing (3 seconds off, 10 seconds on) will make the water flow pulse and make the flushing effect better.
2. Turn off the sewage faucet and turn on the purification faucet. After 5 minutes, the water can be used normally.
1. Cleaning method of activated carbon filtration equipment for drinking fountains:?
1. The wires, pipes and nets wound around the outer ring should be washed with high-pressure clean water, lightly brushed, soaked in chlorine-containing bleaching powder solution for one hour, and then washed with clean water after being taken out.
2. The simple cleaning method of granular activated carbon is to pour out the activated carbon particles, rub them with clear water several times and put them back.
3. Correct cleaning method of granular activated carbon: soak it in dilute hydrochloric acid for four hours, then rinse it with clear water, then dry it in an oven at 200℃ for three hours, then rinse it with clear water after taking it out to restore its activity.
Second, matters needing attention:
1. Drinking fountains should not be placed in direct sunlight, especially those with water purifiers. The filter of the water purifier contains active carbon, medical stone, mineralized ball, perlite and other raw materials. And it is easy to produce green moss under sunlight. After repeated experiments, the service center proved that the filter screen in the water purifier can produce green moss in 20 minutes at the earliest.
At the same time, the drinking fountain should be cleaned regularly. Drinking machines using bottled water should clean the cold bladder (for cold water) once every quarter; Drinking fountains with water purifiers should be cleaned once a month. The hot bladder (used for boiling hot water) in the water dispenser should be cleaned by a professional department. ?
3, cleaning methods, one is to use a special cleaning agent to clean, the other is to ask professionals to clean, and there is an indigenous method that you can also clean the filter with vinegar. After replacing or cleaning the filter element, the water flow will be smooth.
