Hardness removal filters

What is hard water?

Hard water means water with a high content of calcium and magnesium salts (also called “hardness salts”). It’s quite easy to understand that your water is hard:

scale in the kettle;
limescale deposits on the water tap;
white stains on the dishes after washing;
iridescent film in a cup of tea.

If anything from the list is true for you, it signals the need for a softening filter.

Water hardness can lead to some serious consequences:

Household appliances like multicooker, electric kettle, and washing machine can be broken easily in hard water. Heating elements fail, and repairing them is expensive and not always possible.
Homemade dishes and drinks become bland: hard water poorly “absorbs” taste and aroma components.
For people prone to the accumulation and deposition of mineral salts in the body, there is a risk of kidney stones’ formation.
Hair loses shine and becomes brittle. Skin gets irritated and dry.

How can water be softened?

There are two ways to soften water at home: reverse osmosis filtration or ion exchange.

Reverse osmosis

Hardness salts are retained by a special membrane and then washed off into the drain along with harmful impurities. The membrane cuts off even nitrates, pesticides, and viruses that cannot be removed by other filtration technologies. The mineralizer in reverse osmosis filters (in AQUAPHOR filters we use the natural mineral dolomite) returns a small amount of Ca and Mg, which is also good for the usual pleasant taste of water.

Ion exchange

Hard water treatment occurs due to a special material (ion exchanger) that catches calcium and magnesium ions with its surface. In exchange for each of these ions it gives up two sodium ions, neutralizing water hardness. In filters with ion exchange resin, no mineralizer is needed.

How to choose a filter for hard water?

Depending on the type of premises, the quality of incoming water and the intensity of its consumption, several options should be considered. The price depends on the filtration system type and the water treatment volumes.

If the water is not too hard (<120 ppm), you can use the softening adsorption systems. AQUAPHOR softening filters are marked with the letter “H”: for example, ECO H Pro.

This filter has a cartridge with ion exchange resin. Its performance can be with the regular table, just follow the instructions written in the manual. However, if the water is too hard, you will have to regenerate a softening cartridge every couple of weeks, this is inconvenient and not budget-friendly.

If you doubt the characteristics of your water or know for sure that it is too hard, choose a reverse osmosis filter. RO water purification is of the highest quality, and hardness salts content will be dramatically reduced.

AQUAPHOR RO series filters take up less space than conventional reverse osmosis systems due to the compact built-in storage tank. Five times less water is discharged into the drain, which reduces the load on the cartridges, so the whole system lasts longer.

If you want to protect the condition of your skin and hair, as well as prevent possible allergies and eczema in infants and children, a whole-house softener is the right choice for you. Washing and taking a bath or shower in soft water is healthier and much more pleasant. In addition, buying a softening system helps to protect all kinds of household appliances.

AQUAPHOR S series softeners are very compact, suitable for both cottages and apartments. They are more economical and user-friendly than standard column and cabinet softeners. The sorbent serves for a very long time (approximately 10 years) and doesn’t require replacement through the entire period of service. Connecting the AQUAPHOR softener to water pipes is no more difficult than connecting a washing machine, and everything you need for installation comes with the filter.

In order for the water filter to efficiently remove hardness salts and harmful impurities, it is important to change the cartridges on time.
