Is it Ok to Use Tap Water in a Humidifier

Today on the home appliance market there are climatic devices such as air humidifiers that maintain the humidity in the room. They differ in appearance, performance level, and power parameters. Below we will take a closer look at which liquids for humidifiers are best used in order to ensure high-quality and durable operation of the device.

Water characteristic parameters

One of the main indicators to look out for when choosing a humidifier fluid is water hardness.

The level of hardness depends on the amount of calcium and magnesium salts contained in the solution. Conventionally, this indicator is differentiated into temporary and permanent stiffness. In the first case, the hardness is due to the presence of carbonate salts, and in the other, non-carbonate salts.

For reference! In the process of boiling water of temporary hardness, salt deposits settle on the walls of the device, which degrades the performance of the humidifier.

What can i use instead of distilled water?

It is allowed to fill humidifying devices with both untreated water and filtered water.

Untreated water can be easily obtained from the tap. This is the most budget-friendly option that does not require any expenses.

A reliable way of filling a humidifier is considered to be a special purified liquid. However, in order to purchase such consumables, you should be prepared for the costs.

Purified water means distilled, the demineralized or artesian liquid that has gone through several stages of purification. It does not contain salts or other impurities.

Can I put tap water in a humidifier?

This question worries many. In fact, the answer to it depends on the presence of a filter in the humidifier. It is a replaceable cartridge that is able to soften water and remove mechanical particles from it. The only drawback of the filter is that it must be replaced systematically – about once every 3-6 months, depending on the quality of the water. If you forget to make a replacement, then the negative effects described above will be observed.

Probably, we have described all the points that relate to water for humidifiers, if you have any questions, leave them in the comments.

How to choose the right water for your humidifier?

Before installing a home air humidifier, you must carefully study the operating instructions for the mechanism and familiarize yourself with the requirements for the filling fluid.

If the manufacturer does not give precise recommendations for refueling, then the principle of operation of the device as a whole is taken into account. Some models operate with heating, while the rest of the devices are able to turn on “cold”. Also of great importance is the presence of a cartridge equipped with a filtration system for water purification.

Taking into account the above characteristics, you can easily select the optimal source of refueling for the HVAC equipment.

For reference! The water that has passed through the walls of the cartridge becomes softer. The salt content is markedly reduced.

Which water is suitable for steam humidifiers

Steam humidifiers are considered to be easy to maintain. Springwater, distilled water, and demineralized water are suitable for steam appliances. The only condition for the operation of the device is filling the vessel with a liquid that has necessarily passed filtration.

What kind of water is suitable for cold humidifiers

The filter will be less clogged and will last much longer if you use purified water for humidification. It is a distilled and demineralized liquid.

Which water is suitable for ultrasonic humidifiers

This type of climatic equipment reacts very sharply to the components that make up the fluid. It is recommended to use only distilled water in ultrasonic devices. Without mechanical filtration, any moisture will negatively affect the internal elements and clog the evaporation channels.

On a note! Filters responsible for additional cleaning include devices with a metal or plastic mesh. The charcoal or polyphosphates added to the filter are unable to fully purify the incoming moisture.

High-quality water increases the service life of the equipment, avoids breakdowns in the operation of climatic equipment, and guarantees a thorough purification of the air in the room.

Humidity is one of the most important indicators of the microclimate. High humidity often causes fungus and dampness. On the other hand, dry air also poses a serious threat to the body and leads to respiratory and cardiovascular problems. Moderate hydration is the main purpose of a good moisturizer.

Water use in different types of humidifiers


The principle of operation of this device is based on the saturation of air with water vapor. When heated, the water turns into a vaporous state and is sprayed around the room. As the liquid is released from the reservoir, it is thoroughly cleaned with a filter mesh and silver particles. Thanks to the ultraviolet light that the lamps emit, an antibacterial treatment is performed, after which the humidified air is sprayed throughout the room.

As a result of the operation of the humidifier, the microclimate improves, breathes freely and easily, since optimal conditions are created for a person.

The liquid-filled into the reservoir of the device adjusts the parameters of the humidity of the air in an enclosed space. Modern models are refueled in different ways. Some of the first heat the water to convert it into steam, which increases energy consumption.

How to pour water into a humidifier

In the complete set of each household humidifier, there must be an instruction in which the algorithm for using the unit is described in detail. In most models, water is supplied to a removable tank, for which it must be separated from the body, filled with water, screw on the lid, and reinserted. However, some gadgets provide for a simple filling directly into the structure, and the most “advanced” ones are equipped with a special display, with which you can control the level of the incoming liquid.

To extend the life of the product and increase the efficiency of the process, you need to adhere to simple but important rules every time:

  • During preparation for the operation, the device must be disconnected from the mains.
  • Before pouring water into the humidifier, you need to make sure of its quality.
  • The volume of the liquid to be poured must correspond to the displacement of the tank – it is unacceptable to overflow the water beyond the required level mark, as this will lead to a breakdown of the device.
  • It is allowed to turn on the humidifier only after it is completely assembled, and there is enough liquid in the container.
  • It is recommended to regularly, at least once a week, clean the reservoir from the plaque formed there. The water in the tank also needs to be changed at least once every 5-7 days.

Water quality plays an important role in the correct operation of any humidifier, but if ordinary purified tap water is enough for a steam device, then cold and ultrasonic units only need distilled and demineralized liquid. If this condition is neglected, the cartridges will quickly become clogged, as a result of which the performance of the device will significantly decrease. In addition, there will be a need for frequent replacement of consumables, making the use of a humidifier too costly for many customers.

Steam designs, as the most unpretentious, have a wider range of uses than other types of devices. For example, decoctions of medicinal herbs can be poured into them or the air in the room can be scented with fragrant essential oils, adding them to a special compartment or applying a drop to a high spout.

Using all the capabilities of modern humidifiers correctly, you can not only create a comfortable microclimate in the house but also protect yourself from a number of diseases, preserve interior items and protect equipment from damage.

What the wrong choice is fraught with

If during the operation of the device, the model, its type, and manufacturer’s recommendations are not taken into account, the consequences will be as follows:

  1. The parts of the appliance are covered with scale due to the accumulation of salts. In the process of regular use, the layer of this scale increases, it is difficult to remove it;
  2. The heating tube or ultrasonic membrane is also covered with sediment, which reduces the performance of the device and ultimately leads to breakdown;
  3. Substances and harmful impurities settle on all surfaces in the room and accumulate in the human lungs.

It is very simple to determine that a low-quality liquid is poured into the tank: it changes color and stains the walls of the device, lime deposits appear on the heating elements, the smell in the room becomes unpleasant, musty. A solution to the problem is the choice of high-quality water or replacing the humidifier with a more unpretentious model. If you strictly adhere to the manufacturer’s recommendations, the device will work effectively over a long period of time.

How do you know if the water is of poor quality?

To understand that the water is not suitable, it is enough to look at the tank and horizontal surfaces in the room. If a white or greenish coating quickly forms on them, then the water needs to be changed.

Before pouring in a fresh portion of water, be sure to remove the remnants of the old one.

Other important signs:

  • The remaining water in the reservoir has turned dark or cloudy.
  • An unpleasant odor is emitted from the tank, membrane, or filter.
  • A greenish coating or mildew has appeared on the walls of the parts of the humidifier.
