Comparison water softener vs Dropson



Water Softener


Will my installation be protected against limescale?


Yes Yes

Both systems are designed to fight against limescale : the water softener is a chemical system that captures calcium ions and releases sodium (by means of ion exchange resins).

The Dropson systems use a physical process to prevent limescale formation.

Does the system eliminate calcium?



Physical systems prevent the formation of calcium carbonate (lime) without eliminating the calcuim. DROPSON physically treats the water and the calcium carbonate becomes non fouling.

Lime crosses the installation without setting on any surface and is flushed through taps and drains.

Will the system reduce lime formations already present in my installation?

Không Yes

The Dropson systems are able to prevent lime formation in your installation. They will also dissolve the lime already present in the installation.

Is the system corrosive and may it damage my installation?

Yes No

Water softeners exchange calcium for soduim. Sodium is corrosive and in the mid and long term may be a problem for our installations. Certain boiler manufacturers cancel the warranty of their products if the user installs a water softener that requires salt.

Must I add salt on a regular basis?

Yes No

The water softeners require a continuous supply of salt as they use a chemical principal to treat the water. Dropson uses a physical process and does not require consumables.

Yes No

The water softeners require periodic regeneration of the ionic exchange resins. Water softeners may reject up to 200 litres of water per regeneration. Regeneration frequency may vary from 4 to 7 regenerations per month. Dropson systems do not require any kind of regeneration.

Will the system increase

my water consumption?


Yes No

The annual maintenance costs of a water softener are considerable.

As well as the amount of salt used, the wasted water should be considered too. Dropson systems only require an electrical conection and its energy consumption is very low, camparable to that of an energy-efficient lightbulb.

The water is still drinkable

and suitable for consumption?

No Yes

The water softener modifies the chemical composition of the water. The sodium levels are significantly increased, exceeding the limits allowed by WHO: 200 mg/litre. Water treated by water softeners is not suitable for human consumption.

Is treated water suitable

to water my garden?

No Yes

Dropson systems do not change the chemical composition of water. Sodium levels do not vary.

Dropson is suited for irrigation.

Irrigation by water softeners is advisable as sodium levels are very high.

Will clothes be softer

than before?

Yes Yes

The Dropson antiscaling systems prevent the formation of calcium carbonate in cloth fibres. Water treated by Dropson becomes non fouling. Clothes will be softer than before..

Should I add salt

to my dishwasher?

No Yes

With physical treatments, after water evaporation such as the drying cycle of the dinnerware, water may leave traces in the form of a fine dust of calcium carbonate. These traces are easy to clean as they have not crystallized on the dinnerware. Adding some salt to the dishwasher, the stains will disappear.

Will the stains be visible in my sink or my shower screen?

No Yes

As to avoid lime stains with a water softener, it must be adjusted so the hardness levels are very low. To acheive and maintain these levels so low, there is an increase in the sodium levels and the water becomes corrosive for the installation. With Dropson, even though stains are visible, they are easy to clean.

Is it the best choice for places with high water hardness?

No Yes

With a water softener, a higher hardness implies an increase in calcium/sodium exchange. Water with high sodium levels causes severe corrosion to the installations. Dropson does not modify the chemical composition of the water and prevents lime formation.
