On the surface of the earth on which we depend, the ocean occupies 71% of the total area, with a volume of about 1.37 billion cubic kilometers, accounting for more than 97% of the total water. The remaining less than 3% of the water is what we can drink. Fresh water resources.
And water is one of the basic needs of our life to survive, so it is not difficult to see the importance of water for us.
However, a large amount of fresh water resources are currently polluted by humans. Even if it is treated by the water company, it is still difficult to use. Therefore, many families in our life will purchase water purifiers to purify impurities in the water, so that we can use them with confidence, then the water purifier Can the filter element be cleaned? How long can the water purifier filter be used? How to replace the water purifier filter? These problems have been plaguing many users. Come and uncover the mystery today.
1. Can the water purifier filter be cleaned?
1. The water purifier should be flushed for the first time to flush out the protective liquid in the water purifier. The method is as follows: open the tap, tap water inlet ball valve and purifying faucet, and rinse for 15 minutes until the water is clear and free of foam. Frequently switching the taps during the flushing process (off for 3 seconds, open for 10 seconds) causes the water flow to form a pulsating shock, which will make the flushing effect better. After that, the sewage faucet is closed, and the purified faucet is turned on, and the water can be used normally after 5 minutes of water production.
2, often flushing: the daily use of the tap to take water is the process of flushing the water purifier, it is recommended to open the tap after washing the purified water, flush the trapped pollutants in time, keep clean water The machine has a higher water flux, which extends the service life.
3. Backwashing to restore water production: If the water purifier is still relatively small after passing through the flushing water, you can consider backwashing the water purifier. There is usually a backwash button on the water purifier to reverse the flow of water to flush out the blockage in the filter element.
4. The product that only replaces the filter element does not guarantee that there is no secondary pollution on the inner wall and the water outlet of the outer casing. Different water purification products have different filter replacement cycles. The lower cost PP cotton has to be replaced once a month, and the activated carbon is three months.
5. When the upper tank is filled with water and the water does not flow out or flows out slowly in the main filter, the filter element should be cleaned. The cleaning of the front filter element is very convenient: open the front filter cover, remove the white non-woven fabric, wash it in water or wash it with detergent (note: black carbon fiber can not be washed, only rinse).
Second, how long can the water purifier filter be used?
1, PP cotton filter 3-6 months.
2, reverse osmosis membrane (RO) filter for about 2 years.
3, after the activated carbon (small T33, large T33) filter for about a year.
4. Hollow fiber ultrafiltration membrane (UF) filter element for 3 years or more.
5, the particles are finely washed coconut shell activated carbon filter for six months to one year.
Third, how to replace the water purifier filter?
1. Wrap the wrench on the filter bottle and unscrew the filter bottle in time. (When unscrewing the filter bottle, hold the filter cap with the other hand to avoid loosening the connection of the pre-filter; take out the dirty filter. Drop it and put in a new PP cotton filter. (PP cotton must be certified as a regular brand when it is purchased. Generally, regular brands are printed with a stamp!)
2. Check that the white plastic washer inside the filter cap and the black washer outside the filter bottle are tight. If it is loose, press it tightly by hand.
3, you can observe the PP color of your own through transparent front to determine whether your own PP cotton needs to be replaced. If the PP cotton in your home is serious, you can replace it. If it is particularly serious, you must replace it. Because it is afraid of trouble or saving money, it will damage your health!
4, must pay attention to close the machine water valve (if there is no three-way ball valve on the water purifier, you need to close the total water valve in the home), then open the faucet to empty the water in the water purifier.
5. Install a large half of the tap water in the filter bottle, put the filter bottle back into the filter bottle cap, and tighten.
I don't know if these can give you a simple understanding of the water purifier filter. A small water purifier filter has so much knowledge.
Although many people in our life feel that it is not necessary to purchase a water purifier, here I would like to remind everyone that the tap water flowing out of the water pipe in the daily life may be very clean when it comes out from the waterworks, but after a long distance. After the pipeline is transported, the water quality has been polluted when we enter our home. Only a lot of the pollutants inside can't be observed by the naked eye. The water purifier is used at this time. It can help us to stop harming our body. Harmful substances. Therefore, it is very necessary to purchase a water purifier.
