Water filters are considered essential for both health and finances. If you choose a high-quality water purification filter, you can completely refuse to buy bottled water. And about diseases of the kidneys and gastrointestinal tract from bad water, it’s better not to mention.
But before you buy the first filter that comes across in the store, you should learn how to understand them in detail..
If tap water is not ozonized, but generously flavored with bleach, then you can and should pay attention to simple single-flask filters of the “Springlet” type, in which the service life of replaceable cartridges is at least all 400 liters.
If there are organic residues in the water or it is characterized by increased redundancy, it is worth opting for multi-flask filters. In them, each of the flasks responds to its work. As a rule, the first flask completely and completely purifies water from foreign mechanical inclusions, the second one responds to the complete removal of chlorine, while the third flask, which contains silver-filled cartridges, is able to completely remove the slightest organic residues.
Stationary filters are often used when more distilled water is needed, such as for a heating boiler or washing machine. As a rule, filters of this class are equipped with sawfiber membranes, known for being able to pass through themselves only “pure” water molecules. SUCH water filters are available for sale on SITE / . But in order for the whole system to work with proper efficiency, stationary filters require pre-treatment of water, which is often carried out using coarse filters (they have steel cone filters that are cleaned once or twice a year).
But stationary filters have one drawback – a high price. If you need to significantly soften the water used, it makes sense to pay attention to ionic filters, the cartridges of which use special resins that can retain excess manganese or iron in water with maximum efficiency..
For giving, it is preferable to choose filter jugs. Untreated water is poured from above, which, under the influence of gravity, slowly flows into the lower container. Water, with the help of activated carbon cartridges, is completely and completely purified from chlorine. The only drawback is that water purification is rather slow: the filter is able to purify no more than 1 liter of tap water per minute. On the plus side – no need to use electricity or tap water pressure.
