How to soften hard water at home and with a filter

To find out how to soften tap water in an apartment, you should study the appropriate methods and specialized equipment. Preliminary preparation will help you choose the best option, taking into account the initial conditions, financial costs, and other significant factors.

Why is hard water from a well and water supply harmful?
The presence of specific impurities complicates the qualitative performance of the following work operations:

Excessive salt concentration worsens the taste parameters of water. Separate impurities worsen the state of human health, cause allergic reactions.

How to soften hard water for washing and watering plants (solutions to other practical problems) can be found with the help of a thematic overview. The descriptions highlight the advantages and disadvantages of typical methods.

Choosing the best softening water filter
How hard water can be softened is shown in the following list of technologies:

· ultrafine filtration – eliminates microscopic particles;

ion exchange – removes harmful chemicals (compounds) from the fluid flow;

polyphosphate treatment – prevents the deposition of calcium deposits on the surface of the heating elements;

· electromagnetic impact – blocks the formation of scale at a great distance from the installation site of the induction coil.

We will study professional methods using examples of serial equipment produced by reliable manufacturers.

Under this brand, they produce a wide range of water filters with cartridges (loading) that reproduce softening technologies. Thematic distribution helps to quickly find the desired option in the corporate catalog. To find out how to soften the water in the shower, study the selected items in the “For the bathroom” section.

To prepare a small amount of drinking water, choose a suitable jug with an integrated compact cartridge. When searching for equipment, pay attention to the indicated recommendations for input parameters. The manufacturer produces models for effective cleaning at high concentrations of iron, organics, and other harmful impurities.

Select this option if the particle size is less than 0.01 µm. Aquaris hollow fiber filter will help not only to soften lime water. With its help, molecular compounds, bacteria, and other microscopic fractions are retained.

Hard water can be softened with the Aquaris hollow fiber filter.

A significant advantage is the ability to independently restore the initial state of the working module in case of clogging. Cleaning is carried out by simple washing without removing the hollow fiber membrane from the steel housing. The regular replaceable unit processes up to 500 thousand liters of liquid without compromising functionality. The recommended service life is 4 years.

The noted advantages are provided by electromagnetic treatment of liquid by a force field using an extended frequency range – from 1 to 50 kHz. The most powerful devices of the series operate in difficult conditions with hardness up to 21°F. The range of action up to 2000 meters allows you to organize protection against scale of the entire cottage or other large property with one device.

When looking for kitchen equipment, look for a reverse osmosis kit that softens drinking water using a semi-permeable Aquaporin membrane. This functional component is created using innovative technologies that increase productivity up to 750 l / day. According to this indicator, the installation is 3-3.5 times better than typical analogues of competitors.

With a high concentration of specific impurities, it is recommended to choose equipment from the “Hardness” series. Consider the limited resource of typical cartridges, which, even in the best performance, operate effectively at a contamination level of no more than 4°F.

A separate section presents models that can soften hard water from a well in a private house. When choosing an installation, performance, dimensions, price, and other control parameters are evaluated.

You won’t have to look long for an answer to the question of how to soften water with temporary and general hardness if you choose the direct-flow Osmos Stream system. In this series, reverse osmosis kits are presented, operating with high productivity – up to 63 l

By adding a standard pump to the kit, they ensure the operable state of the installation when the inlet pressure drops to 0.5 atm. An additional advantage is that no more than 50% of the incoming water is discharged into the drain during treatment.

Tips for softening hard water at home
To solve the problem with the help of improvised means, soda and salt, vinegar and boiling are used. Let us consider in detail the reproduction of the relevant technological processes for a better understanding of the characteristic advantages and disadvantages.

Sodium bicarbonate provokes the precipitation of salts. Add baking soda to drinking water (1/2 teaspoon per glass). This treatment helps to normalize the acidity in the stomach. Regular use of liquid softened in this way is recommended only as prescribed by a doctor. For washing, mix soda and detergent equally.

Tableted sodium salt is used to restore the functional state of ion-exchange granules. The solution prepared in a separate tank is passed through the working load layer or used to flush the cartridge. This drug is not suitable for softening directly.

This method, due to an excessive increase in acidity, is not used for the preparation of drinking water. The recipe depends on the intended purpose. To perform cosmetic procedures for 1.5-2 liters of water, take one tablespoon of vinegar.


Softening drinking water at home is easiest with this method. The desired result can be obtained after boiling for 5-10 minutes. High-temperature exposure destroys individual pathogens.

Boiling water as a way to soften water at home

The simplicity of the technology for objectivity should be evaluated in conjunction with the shortcomings. Strong scale is fixed on the walls of the dishes. Reproduction of the method is associated with a large expenditure of time and energy resources. During the boiling process, the level of humidity in the room increases significantly.

Other ways to mitigate temporary, permanent and general water hardness
In addition to the methods considered, for the rapid processing of a large amount of liquid on an industrial scale, dosed addition of reagents is used. The composition of the working mixture is determined by the results of the analysis of the qualitative (quantitative) content of impurities in the source. The technical process is optimized in terms of duration, temperature, concentration of active substances.

Consider separately the question of how to soften water with constant hardness. In this case, we are talking about impurities that are not converted into scale when heated. All impurities larger than water molecules can be removed using reverse osmosis. However, even the most productive expensive domestic installations are not able to provide productivity from 900 l / h, which is necessary to meet the typical needs of a family of 2 people.

The problem is solved by parallel installation of several reverse osmosis membranes. The set of equipment is complemented by:

support stand;


automatic control and management;

· dosing device for regular cleaning of working units;

connecting fittings.

The methods presented in this section of the review are rarely used in everyday life due to the high cost of high-quality equipment. Additional problems during operation are due to the complexity of maintenance.

Conclusions and recommendations
How to soften the water in the washing machine, you can decide quickly using the information provided. “Folk” methods with the addition of soda or other active ingredients are inconvenient. It is difficult to calculate the exact doses, taking into account the initial level of hardness, temperature conditions. It is much easier to solve the designated problem using a cheap polyphosphate filter.

It is much more difficult to decide on the question of how to soften water from a well at no extra cost. Traditionally, ion exchange is used.

When choosing this method, one should take into account the characteristic disadvantages:

The high cost of a well-equipped kit;

large overall dimensions of the equipment;

regular replenishment of the supply of salt tablets;

· performance of functional status checks;

Difficulty in setting when increasing/decreasing the input hardness level.

Abrasives, sulfides, other impurities can damage ion-exchange granules. To extend the service life and maintain the efficiency of the main load, pre-filtration equipment is installed. With a high concentration of calcium in the well, another workstring will be needed to re-treat the fluid flow. The noted additions significantly increase the investment in the project.

Instead of ion exchange, user-friendly electromagnetic processing can be applied. If the size of harmful impurities is not less than 0.01 microns – Aquaris hollow fiber filter. Such a set can be used for the complex preparation of technical and drinking water without the final stage of purification by a reverse osmosis system.
