Puerto Verde's demineralized water is treated to remove the salts and minerals responsible for limescale, making it ready to use in humidifiers, steam irons, batteries, radiators, and all appliances that suffer from tap water. Because it contains no minerals, it leaves no white residue or limescale deposits, extending the life of your appliances and devices.

What is demineralized water and what is it used for?

Demineralized water is water that has had its mineral salts (calcium, magnesium, and others) removed, which are responsible for limescale formation. Unlike tap water, it leaves no white residue or deposits when it evaporates, making it ideal for any appliance or device sensitive to limescale.

It is used in humidifiers and diffusers, steam irons and ironing stations, lead-acid batteries, car radiators and cooling systems, pressure washers, CPAP equipment, beauty devices, and autoclaves, among many other uses. You can find all the information about one of its most frequently asked uses in our article demineralized water for humidifiers.

How to use demineralized water step by step

Use it directly: it does not need dilution or prior preparation; it is used just as it comes out of the container.
Fill the reservoir: pour the required amount into the reservoir of your humidifier, iron, or appliance, following the manufacturer's instructions.
Keep the container tightly closed: once opened, keep it closed and in a clean place to prevent contamination.
Repeat with each use: replace tap water with demineralized water every time you refill the appliance to keep it continuously free of limescale.

⚠ Before using it: Demineralized water is not suitable for regular human consumption, as it lacks the minerals provided by drinking water. It is formulated for technical use and in household appliances. Always consult the instructions of your appliance manufacturer.

Frequently asked questions about demineralized water

How does it differ from tap water?

Tap water contains dissolved minerals (calcium, magnesium) that, when evaporated, leave limescale deposits. Demineralized water has been treated to remove those minerals, so it does not create limescale or white residue in your appliances.

Is it good for humidifiers?

Yes, it is the recommended option. Tap water in humidifiers usually leaves a white limescale dust suspended in the air and on nearby furniture; demineralized water completely avoids this problem. You can find all the details in our demineralized water for humidifiers guide.

Can it be used in car batteries?

Yes, it is the recommended water for refilling lead-acid batteries, as tap water can introduce minerals that reduce the battery's lifespan.

Can you drink demineralized water?

It is not recommended for regular consumption, as it lacks the minerals present in drinking water. It is designed for technical use: household appliances, batteries, and devices sensitive to limescale.

What size should I choose?

It depends on your consumption: the 1-liter container is ideal for trying the product or very occasional use, the 5-liter container covers regular household use, the 10-liter container is more convenient if you have several appliances or frequent use, and the 20-liter container is designed for workshops, businesses, or intensive use.
