Many residents of our country use pitcher filters to purify water, while many are confident that this is the only effective way of disinfection. Such products are widely represented on the shelves of our stores. Why are they really effective? Let's talk about it.
What filter jug is it and how effective is it
A pitcher filter is a flow type device. That is, water purification occurs when it passes through a replaceable filter cartridge.
Inside him The following substances are found:
- Activated carbon;
- ion exchange resins and some others.
The use of such a filtering device allows eliminating particles of chlorine and its compounds, traces of oil products and many other impurities from the water supply. Thanks to the operation of this device, the liquid acquires transparency, the foreign taste and smell are eliminated.
Some manufacturers equip cartridges with materials that contain silver ions. This allows bacteriological disinfection of the fluid supplied from the pipeline system.
Using such a filter allows you to reduce the hardness of water, reduces the rate of scale formation in the kettle.
A sieve installed in the cartridge holds large mechanical particles.
The capacity of such a jug is an average of 3 - 5 liters.
When choosing such a device, the consumer should be aware that products of this type are not quite adapted to soften water. The concentration of salts in the water supplied from the water supply can be quite high and the jug is not able to completely remove them. In this case, the installation of an additional reverse osmosis cartridge does not hurt. Some companies have mastered the production of such replaceable cartridges for jug products.
In fact, pitcher devices will show their effectiveness at salt concentrations of not more than 3-4 mg per liter. I.e for cleaning soft or medium water.
Structurally, such a device consists of a container, a cleaning element, a cover.
The container is divided into two parts, liquid from the tap is poured into the upper section, under the action of gravity, it passes through the cartridge and purified water is collected in the lower section.
Regardless of the manufacturer’s device design, the appearance and size of the container may differ. Some manufacturers have mastered the production of such products with a capacity of less than three liters. This device can be safely used by children.
Advantages and disadvantages of filter jugs.
A device of this type, used for purification of tap water, is distinguished by its simplicity and efficiency, but meanwhile, this product also has some disadvantages. Let's consider it in more detail.
The advantages of these products include:
Compact design and their mobility, size allows you to store anywhere in the kitchen, for example, on a table, window sill. It can be put in any place at any second.
Purification level - for small dimensions, they successfully cope with the purification of water from various impurities.
Price - in comparison with specialized devices that are installed under the sink or built into the plumbing system, devices of this type are available to a wide range of consumers.
The disadvantages of such devices includethat for the effective operation of the device requires a fairly frequent filter change.
The compact size does not make it possible to handle a large amount of water, for one person or a small family this is not a problem, but for families of several people, this can create certain difficulties, in which case it makes sense to think about using another treatment system. For example, installed under the sink or built into the piping system.
Is it possible to further filter the water if the cartridge has expired.
Depending on the quality of the water supplied to the house, the cartridge may have a different service life.
Long-term operation of the filters shows that in a family of four and consumption of 10 liters of water per day, it is advisable to replace the cartridge in two weeks. In some families, the use of the filter continues for a long time, without paying attention to the manufacturer’s recommendations and forgetting that both filtered parts and harmful microorganisms accumulate in the replaceable cartridge, that is, the liquid that has passed through the filter will not only become cleaner, but will absorb previously eliminated contaminants, and the bacteria present in it. Causing an unjustified danger to the life and health of one's loved ones. One conclusion can be drawn from this - the use of old filters is unacceptable.
Which cartridges are better to choose for a filter jug.
When selecting a filter, you need to remember that not every device can be used to purify the water flowing from the water supply. It is advisable to know what characteristics water has in the system. In one case, the amount of iron may be exceeded in it, in another, calcium and already guided by these data choose the optimal filter.
What to do if the filter jug becomes cloudy.
During the operation of the filter jug, plaque may form on its inner walls. It is formed in water due to the presence of various impurities of organic and inorganic origin.
To keep the jug clean, wash it using standard detergents.
