(a) understand their own water quality and demand
Select water purification equipment device before the first to understand the water quality of their own homes, it is best to test, generally their own home is not very good at mastering, so if it is a new neighborhood, you can owners together with the manufacturers to ask the manufacturers to test a time, because as long as the detection of a household to know the water quality, the same building water quality is the same. Also, to understand their own home is the tap water supply, or community well water supply, and then according to the actual need to install water purification equipment.
(B) understand the function of water purification equipment and late investment
When you choose water purification equipment, first of all, we must understand the function of water purification equipment, water purification equipment is mainly used for two parts, one is drinking water, one is living water, these two functions are with two kinds of equipment, pure water machine, water purification machine is used for drinking water, and water softener out of the softened water is not suitable for drinking, and only applicable to the shower or washing clothes.
In summary, water purification equipment in the treatment of drinking water filtration (PP cotton, activated carbon, microporous ceramics, ultrafiltration, etc.), reverse osmosis, electrodialysis and so on.
Understanding the performance of the water purification equipment, followed by the need to know its cost-effective, do not just look at the purchase price, but also to see if there is no late fees, shopping for water purification equipment to be prepared, because some are not a one-time investment, there is a late investment, and the cost is not low. Filter cartridges need to be changed, water softeners have to play salt, these costs are considerable, some used after a few years, these costs are enough to buy a new one, so we buy this type of machine, we must consider the later costs.
The replacement time of the filter depends on the use of water quality, water pressure and the size of water consumption, the more serious the pollution of the water source, the shorter the annual replacement of the filter cycle, the higher the cost of the general water purifier and water purification machine cartridge service life of 3 months ~ 5 to 6 years ranging from the reverse osmosis membrane of the water purifier service life of about 24 months, the water purifier each year to change the average cost of the cartridge is about 500 yuan or so, the water purifier The average annual cost of filter replacement for water purifiers is about 500 yuan, and for water purifiers it is about 300 yuan.
Pure water machine and water purifier is through filtration to achieve the purpose of purification, filtering material after a period of time will adsorb a lot of impurities, should be replaced in a timely manner the filter material, otherwise a long time, on the contrary, it will be the secondary pollution of the water source. Also, change the filter element should not be based on time, should be based on the amount of water supply in your home, think of a family of two a piece of the past, another family with children elderly a piece of the past, that water consumption is definitely not the same, and work a family on the evening back, sometimes meals are not at home to eat, and older, washing and shuffling three meals a day are home, that water consumption is also not the same, so it is still according to the amount of water consumption to calculate the more accurate some.
Buying a water softener manufacturer will not tip you on how much it costs to hit the salt in a year, the price of some of the larger models are seven or eight thousand, a lot of people buy water softeners feel that the price is not affordable, most of them are to choose the cheaper manual small models, do not take into account the quality of the water in their own homes and the amount of use. Large models can be up to a week or two weeks to play a salt, mostly automatic cleaning, small models are cheap, such as manual salt is very troublesome, in accordance with Beijing's water quality, small models of water softeners to frequent salt, salt than the large models, water softeners is to buy the larger the later the more salt.
(C) understand what kind of water purification equipment they need
Elect water purification equipment to understand what kind of water you want to get, I turn in the electrical city, I always see people ask sales, "is it good to buy a water purifier, or water softener good?" In fact, this is two concepts, one is to drink, one is to use, even the function of the water purification equipment have not been able to understand the rush to buy, definitely will not choose the right, there are a lot of people want to buy a water softener, because boiling water is too much alkali, the pot is white thick alkali, that is, loaded with water softeners, that your home pots of how much alkali is still how much alkali there is, because the soft water is not suitable for drinking.
