Jug Type Filters

The filter jug ​​is the most affordable and primitive way to purify water. The main purpose of the device is to purify water from chlorine, mechanical impurities, remove unpleasant odors and improve color, as well as partially rid the water of hardness.

Filters are compact, mobile, they can be used both at home and on the go. The devices are easy to operate, with them clean water is always at hand, and besides, the price is low.

Important! However, all models require frequent replacement of the filter element, since the cartridge life is very small, usually up to 300 liters. Therefore, once a month or two, its replacement is necessary.

Filter jugs are convenient for use in a family of 2-3 people or a small office.

Important! Act as a filter element: activated carbon or silver ions. The maximum degree of purification is 20 microns.

Pros:

• Such a water filter is extremely easy to operate.
• It does not require a water connection.
• Mobility of use. The device can be used at home, in the country and on vacation.
• No control required.

Disadvantages:

• Small volumes of purified water.
• The degree of purification is lower than that of filters connected to the water supply.

Device and method of action

The principle of operation of the device is as follows: water is poured into the jug and it flows by gravity from one container to another, passing through the filter element. The volume of purified water directly depends on the volume of the jug - as a rule, this is one or two liters.

Important! If you need three liters of water for cooking or a drink, you will have to fill the jug twice, which is not very convenient.

Modern device models are equipped with:

• Spout for convenient transfusion of water into another container.
• Cartridge resource indicator.
• Flip, which makes it possible to pour water into the jug without removing the lid.

Important! Water filtration rate - from 3 to 10 minutes. A pitcher filter is the best option for those who cannot make space under the sink for a stationary system. Do not use the filter for longer than the required resource, as this is fraught with health.The jug itself also change once a year.

Fillers for household cleaners

Household water purifiers have various filter elements and they are selected depending on the needs. Therefore, in order to decide which water filter is best for a house or apartment, it is advisable to first make a chemical analysis of the composition. Then, consider that each cartridge performs its function and determine the appropriate one for specific tasks:

• Mechanical - removes sand, rust, various suspended particles. By its work, this cartridge extends the life of subsequent filters.
• Briquetted charcoal - removes residual chlorine, organics and other small particles.
• Granular coal - removes heavy metals, eliminates odors and gases.
• Mineralizer - saturates with minerals.
• Bioceramic filter - restores the natural structure of water.

Important! Basically, the purification system consists of several filters, and the more degrees of filtration, the better the purified water will be. Stationary filters for water purification are chosen by those users who understand the value and importance of high-quality filtered water, and are ready to invest money in their health.

Reverse osmosis systems

The best filters for water purification are reverse osmosis filters. They allow you to remove not only mechanical impurities, excess iron and chlorine, excess rigidity, but also purify the water from all kinds of viruses and bacteria. This category of filters is considered the most complex, expensive, but also the most reliable.

Important! After using the system, water is purified by 99%.

Osmosis is prompted by the most natural system and works on the principle of a cell membrane. Features that are already appreciated by many consumers are as follows:

1. The key filtering element of the system is the reverse osmosis membrane, the pores of which are much smaller than most viruses. So - your body will be reliably protected from microorganisms.
2. Thanks to reverse osmosis systems, it became possible to replace bottled water at home, while significantly saving money.
3. Thanks to such a system, the water is filtered to such a state that it does not even leave a deposit on the heating elements of household appliances.

Benefits:

• The highest degree of purification.
• A constant supply of purified water (10 liters in a tank).
• Low cost of filtered water.

Important! Before installing a reverse osmosis system, measure the pressure in the water supply system - it must be at least 2.8 atm., Otherwise - the system will not work properly.

Disadvantages:

• The complexity of the installation.
• The complexity of the service. All actions with the system must be performed by a specialist.

Equipment

The standard equipment of the reverse osmosis installation includes:

• Pre-cartridge system.
• Membrane reverse osmosis.
• Special post-filter.
• Devices can be understaffed, if desired, with a mineralizer and a structurizer. They will enrich the water with minerals and make them useful for digestion and blood circulation.

Important! The frequency of replacement of the reverse osmosis membrane - 1 time in 3 years, the frequency of replacement of post-cleaning cartridges - 1 time per year. Reverse osmosis systems are the most efficient and top the filter rating, because the maximum degree of purification is 0.0001 microns. Such water filters are chosen by people who want to constantly consume highly purified water and not overpay for it.

Ultrafilters

The working element of ultrafiltration systems is a membrane consisting of a tubular composite. Installing a filter with such a membrane will purify water from bacteria, viruses, and preserve the original mineral composition of water.

Important! The membrane is a reliable filter from pests, since the diameter of its holes is 20 times smaller than the size of all known viruses and more than 300 times smaller than the size of bacteria.

The principle of operation of the ultrafilter is the same as the reverse osmosis system, but the ultrafilter is more expensive. Which system to choose, you decide, based on financial capabilities and needs.

Which water filter to choose for the home?

By acquiring a cleaning system, everyone strives to choose the best water filter.

The following factors must be considered here:

1. Environmental friendliness and safety for humans. Since the water purifier is constantly in contact with water, it must be made of environmentally friendly materials that are absolutely safe for humans.
2. Compliance of materials used in the manufacture, quality standard. The presence of any chemical odors on the filter components is excluded.
3. Strength and reliability of the design.For a stationary filter connected to the water supply system, the reliability and durability of the housing material are very important. In modern models, glass-filled plastic is preferred.
4. The ability to reduce the concentration of harmful substances during normal operation.
5. The ability of the cleaning system to prevent the propagation of harmful microorganisms.

What should be considered when buying a household filter for water purification?

In order to choose the best water filter, decide on the type of device and listen to the following recommendations:

1. Filters working on a similar principle do not have fundamental differences, and the price depends on the manufacturer (brand) and the quality of the materials.
2. When choosing a filter, pay attention to the following characteristics:
   • The number of cleaning steps.
   • Features of filtering. Ideally, before choosing a purifier, it is necessary to examine tap water for the presence of elements in it. And then, pick up a purifier that can cope with the greatest amount of pollution in your water system.
   • The presence of a mineralizer. Usually, the mineralizer is installed by default, so decide whether to use it or not.
   • Performance. If the family is small, then a jug filter is sufficient, if the family has many households, then pay attention to stationary systems.

Helpful hints:

1. When choosing a water filter, be sure to pay attention to the quality of the flask (housing). Pay special attention to the quality of the plastic and appearance: casting defects, gaps at the joints, and irregular geometric shapes should not be present on the case. Choose a model from thin-looking but heavy plastic.
2. Choose a system housing with a double rubber seal. Such devices are more durable in operation and withstand more pressure.
3. Pay attention to the connecting elements of the filters.
4. Pay close attention to the crane, which is exposed to daily use. On expensive models, faucets have a polished ceramic seal and a rotary handle. In cheap models, this design was replaced with a plastic lever handle. The disadvantage of this design is the frequent breakdown of the handle. And since this part is not included in the filter kit as a spare part, you will have to change the entire valve.
5. Do not forget about caring for the filter, plan to change the filter elements, as they are the guarantor of the quality of the cleaning system.
6. The following points should be indicated in the accompanying documentation:
   • Certificate confirming compliance of the filter with all technical specifications.
   • A method for removing debris and impurities is described.
   • A method for disinfecting water is described.
