The lead in drinking water event in earlier year arouses people’s attention again and citizens remove lead in different ways to ensure health of family members. Installation of the water filtering plant is the most convenient method. It is indicated in many literatures that water filter could effectively remove the lead and other impurities in the potable water to make the necessary portable water healthier. However, there are many categories of filters on the market, how consumers select the proper one? The article below will give you some tips.
Water filtering has filtration mode and electrolysis mode which have respective advantages and disadvantages. Meanwhile, there are various types of filters even in the same filtering mode. It does not matter and we introduce you each water filter and help you select the suitable one.
Filtering pot
This option is relatively cheap that you only need to pour portable water into the pot and drink the filtered water after half an hour. Unfortunately its filtering effect is not perfect and the filter element must be frequently changed, which is not convenient.
Tap-typed water filter
As one of the easiest installation modes, it is cheap and affordable. The small volume is suitable for each family. It is the elementary water filter. But if you want to remove the lead, it is still difficult. Since the filter element is relatively smaller and its filtering performance is poorer, it could only filter some fundamental impurities. Meanwhile, the element needs to be changed frequently because it is easy to accumulate bacteria that the maintenance cost is relatively higher.
Water filters with ceramics filter elements
Diatomaceous earth is mainly used to filter portable water. Most of such filters receive the filtration certification so you should purchase the certified brand to guarantee its effect. The filter element is not necessary to be changed frequently. However, the water filters with ceramics filter elements occupy more space and some brands need to be professionally installed, the first purchase may be troublesome.
RO filtering device –(REVERESE OSMOSIS)
It is also called as “zinc plate-typed filter”. If you want to enjoy better quality water regardless of the cost, such filter will be the best choice. It needs to be installed by professionals. Although a large space below the zinc plate has been occupied, it guarantees excellent filtering effect thanks to the multiple filter elements.
Water filter with activated carbon filter elements
The activated carbon with strong adsorption power is used as the main filtering material to effectively absorb bacteria and impurities in portable water without changing its volume. The disposable filter element is convenient that users need not to wash it. It achieves the average water filtering effect in all aspects that it is widely used in many stadiums.
Electrolyzed water
Electrolyzed water has been applied in agriculture and medicine earlier. Along with its popularity, many families have such electrolyzed water machine. It breaks down the molecule in the purified water through electrolysis into alkaline electrolyzed water for drinking since it contains positive cons of calcium, kalium, magnesium and sodium, etc and acidic oxidizing water used for beauty and other disinfection purposes since it contains negative ions of chlorine, trihalomethane, phosphate, sulphuric acid and nitric acid, etc.
It has been pointed out that alkaline electrolyzed water removes reactive oxygen species (free radicals) that block the oxidation of DNA in human body. Drinking for a long time can improve body function. Therefore, electrolytic water has become necessary device for many health enthusiasts.
Electrolytic water machine has a variety of installation modes, suitable for different families. Meanwhile it is not big and the filter element needs to be replaced for 6 months to one year. It is very convenient.
Having known various water filters, the Consumer Council reminds you to understand the National Health Foundation’s NSF 53 certification. Such certified water filter can reduce lead to 10 micrograms per liter. If you purchase the water filter mainly to remove the lead, you should pay special attention to see whether the water filter has such certification.
