Today filters for water purification are of three main types: filter jugs and nozzles, a sorption filter "for washing", a reverse osmosis filter. Jug filters are the simplest and most convenient type of filters. Water is poured into the jug and cleaned by flowing through the built-in cartridge.
The scale in the teapot reminds you that water is not only H2O. Salts, bacteria, dirt - all of these are contained in the water. It doesn't matter if you take it from the tap or in the pump room next to the house. The problem is solved by purchasing a water filter.
How to choose a water filter?
Consider what they are. There are such types:
- filter jugs;
- tap nozzles;
- flowing;
- filter bottles.
By the method of cleaning, they are divided into:
- mechanical;
- ion exchange;
- reverse osmosis.
The choice of a water filter is based on three criteria:
- the quality of the water from the mains. The following signs indicate problems with water:
- metallic taste - there are iron compounds in the water;
- scale in the teapot - a lot of salts;
- foam when washing aluminum dishes: high concentration of alkali;
- stains after washing silver dishes: there is hydrogen sulfide in the water;
- odors: presence of organic compounds;
- brown sediment: contamination with iron oxides.
- volume of consumed water. On average, a family of 4 consumes 10-12 liters of drinking water per day;
- location.
Let's consider the advantages and disadvantages of different types.
Jug type filters
Construction: jug-shaped container with a cleaning cartridge at the top. Water passes through the cartridge and enters the container.
Characteristics:
- cleaning quality: The cleaning element retains dirt and sand. Poorly copes with cleaning from chemical compounds, chlorine and heavy metals;
- performance: 1 liter in 5-7 minutes. Carbon cartridges are changed frequently as they become clogged. One cartridge is designed for ~ 250-300 liters;
- accommodation: the dimensions of the jug are small, they are placed in any convenient place.
The pitcher filter cartridge must remain in the water at all times. The quality of cleaning will decrease dramatically if you keep it dry for several days.
Dignity:
- cleans from mechanical impurities and reduces chlorine content;
- compact, easy to use;
- low price (~ 130-350 UAH).
disadvantages:
- average quality of cleaning;
- cartridge resource is limited (250-300 l).
Recommendations: pitcher filters are bought if the water quality is relatively good. Suitable for a family of 2-3 people. Famous brands of this type are Brita and Electrolux. The products "Aquaphor", "Nasha Voda" and "Barrier" are relatively inexpensive and effective.
Flow filters
Such units are built into the water supply system. Water accumulates in the tank. Multi-stage filtration eliminates mechanical impurities and harmful substances.
Expensive models have a reverse osmosis system and a mineralizer. Osmosis purifies water, including bacteria. Since osmosis makes water almost distilled, a mineralizer is used. It enriches it with useful microelements. Water is supplied to a separate tap. The possibility of two streams is provided. Fully purified water is used for cooking. The water that has passed through the mineralizer is drinkable. Such devices have both high cleaning quality and performance.
An infrared cartridge is recommended to improve water quality. The water that has passed through it has a beneficial effect on the body. Such cartridges are installed instead of the mineralizer, or together with it.
Characteristics of this type:
- cleaning quality: high;
- performance: 1.5-2.5 liters per minute;
- accommodation: where it is convenient to connect to the water supply. Often placed under the sink in the kitchen.
Dignity:
- high degree of purification;
- great performance.
disadvantages:
- difficulty in installation;
- high cost (~ 1000-3500 UAH);
- expensive consumables. For example, a set of filters costs ~ 200-600 UAH. Reverse osmosis membrane - UAH 500-600;
- site restrictions.
Recommendations: flow-through filters are chosen if the water pollution is significant and / or the water consumption is high. Popular brands include Aquafilter, Atoll, Bluefilters, Raifil, Honeywell.
To purify very dirty water, a main pre-filter is installed. It cleans water from mechanical impurities, sand, clay particles. They are installed not only with a reverse osmosis system. It is recommended to place it in front of appliances that are sensitive to water quality. For example, washing machines, dishwashers. Buying a pre-filter will reduce the cost of repairing household appliances.
Attachment on the crane
The container with the cartridge is connected to the water tap through the nozzle. In terms of cleaning quality, they are close to the jug type, but more convenient to use. Some models have a switch that bypasses the filter.
Characteristics:
- cleaning quality: average;
- performance: 0.5-1.0 liters per minute;
- accommodation: only on the tap.
Dignity:
- compact;
- easy to install and use;
disadvantages:
- average quality of cleaning;
- short resource of consumables.
Recommendations: Serves as an alternative to pitchers. Moreover, it is more convenient to use. Suitable for small families. Recommended brands: "Aquaphor", "Geyser", Rainfil.
Filter bottles
Water is poured into a bottle and purified by passing through a carbon filter in the lid. Convenient for athletes and outdoor enthusiasts. Also suitable for those who want to save money: replaces ~ 400 plastic water bottles.
Summarize... By buying a filter, you save your health, and also save on the purchase of drinking water and repairs. Household appliances and plumbing will become less likely to fail. Therefore, even expensive installations pay off within a year.
