What is a humidifier and what is it used for?

A humidifier is a device designed to add moisture to the air, increasing humidity levels. It operates by releasing water vapor or steam to improve air quality and comfort. Humidifiers in industrial settings are used to maintain proper humidity levels, ensuring the quality of products in industries such as textiles, electronics, and paper.

They prevent damage to sensitive materials and products in storage facilities by controlling humidity. Additionally, industrial humidifiers enhance production efficiency and worker comfort by creating a stable and optimal environment.

What types of humidifiers are there and how do they function?

Depending on the type of humidifier, it will work one way or another:

Evaporative humidifiers, there are two types

  • Evaporative pad humidifier: In this type of humidifier, air steam goes through a wetted pad. The air transfers energy to the water contained in the pad, which gets evaporated and added to the air, so it gets more humid. The air temperature gets reduced too, so these units are usually used as coolers.
  • Pneumatic atomization humidifier: It consists of a group of nozzles that expel an aerosol that is easily absorbed by the air. This type of humidifier is often used in places where there isn’t AHU (Air handling unit) like in wine cellars. The wood of the barrels is hygroscopic, that means that the wine could get through it and evaporate if the ambient humidity isn’t high enough.

One interesting application of this type of humidifier is how it is utilized during the winter. Once the air has been heated, its relative humidity becomes very low. An evaporative humidifier should be placed right after the heater to increase the relative humidity. Then another heater can be placed to get to an appropriate temperature.

Steam generator: This type of humidifier, as it name says, evaporates water and expels the steam to the air. This type of humidifier is isothermal.

What are the benefits of using a humidifier?

Humidifiers offer a lot of benefits if used correctly. They are able to preserve products for long or short periods of time, depending on the type of humidifier. Domestic humidifiers are mostly used for health reasons, as some people have conditions that require a more humid environment in order to stay healthy. They also help alleviate dry skin, throat irritation, and respiratory issues caused by dry air, especially during colder months or in arid climates. 

Maintaining proper humidity levels can also reduce the spread of airborne viruses and bacteria, promoting a healthier indoor environment. Additionally, humidifiers can protect wood furniture, museum artifacts, and other sensitive materials from degrading due to low humidity. Overall, using a humidifier can enhance both physical well-being and the longevity of products in dry indoor settings.

Main differences between industrial and domestic humidifiers

The main differences between domestic and industrial humidifiers lie in their capacity, design, and application. Domestic humidifiers are designed for smaller spaces, such as individual rooms or homes, and typically have lower output and capacity. They focus on enhancing personal comfort and alleviating minor health issues caused by dry air.

In contrast, industrial humidifiers are built to handle large-scale environments, such as factories, warehouses, and production facilities, with much higher output and capacity. They are engineered to maintain precise humidity levels critical for protecting sensitive materials, ensuring product quality, and optimizing industrial processes. Additionally, industrial humidifiers often come with robust construction and advanced features to meet the demands of continuous, heavy-duty operation.

When and where is it advisable to use a humidifier?

It is advisable to use a humidifier in dry climates or during winter when indoor humidity levels are significantly lower. Areas where people or products spend an extended amount of time are especially in need of humidifiers, in order to keep optimal humidity levels. Specifically offices and workplaces with dry air conditions can benefit from humidifiers to improve comfort and productivity. Using a humidifier in rooms with fragile items, fresh produce, or valuable artwork can help maintain their integrity by preventing degradation due to low humidity levels.

When should you not use a humidifier?

There are several scenarios where it is not advisable to use a humidifier. Firstly, if the indoor humidity levels are already high, typically above 50-60%, using a humidifier can exacerbate issues like mold growth and allergen proliferation, which degrade indoor air quality. Additionally, if there are existing mold or mildew problems in your home, introducing more moisture through a humidifier can further worsen these issues.

It’s also crucial to avoid running a humidifier unattended for extended periods, especially if it lacks automatic shut-off features, as this can lead to excessive humidity levels or potential water damage. If the humidifier itself is not cleaned regularly, it can distribute bacteria, mold, and other contaminants into the air, posing health risks rather than benefits. Certain medical conditions, such as asthma or allergies, may also be aggravated by increased humidity, making it necessary to consult a healthcare provider before using a humidifier.

How long can a humidifier be left on for?

The duration a humidifier can be left on depends on several factors, including the type of humidifier, its capacity, and the specific model’s features. Some humidifiers are in higher-intensity environments so they require much more maintenance and cannot be left on their own for too long. However, humidifiers that specialize in long term storage need sparse and inconsistent manual care, since most maintenance can be done online. Even if in-person maintenance is necessary, it is usually much less demanding.
