What does a humidifier do?

You have probably heard of humidifiers before, and there is a very high possibility that you have seen dozens of humidifiers without knowing what they actually were. Unlike many traditional devices such as radiators or fan-based fans, humidifiers do not have a uniform design or style, and you will often forget to take this into account if you ever move to a new home or job. We at Best of Machinery can help you answer a simple question that many people ask at some point in their lives: “What does a humidifier do?”


Humidifiers have a very simple reason to exist – we had ways to remove moisture from a room, but there were no easy ways to reset them in theThis means that many houses would feel dry in warm weather or heavy snow. Low humidity can make almost anything you do uncomfortable, and humidifiers have been the solution.

Most of them generate water vapor, which keeps the humidity stable in a room or building. Safety measures are often developed to switch off when the air is already too humid. There is a wide range of different designs and variations, but all are supposed to do about the same.

Industrial humidifiers

Industrial models are typically used to ensure the safety of the devices in the first place, rather than to ensure the work of the employees (although this is usually a side effect anyway). They are designed to prevent static electricity from building up and to prevent important materials from drying out. These things could endanger entire production lines and machines if they are not checked. They will also be seen in packaging rooms to make adhesives work, and in cold rooms to keep food fresh and production lines to ensure that the production process runs smoothly.

An average industrial humidifier is much larger than a commercial one. Sometimes it is installed in a trolley and fed with water tanks. Others are mounted on a wall and connected to the water pipe so that they can produce water vapor in large quantities without having to refill them when they are empty. A remarkable sign of a humidifier on an industrial scale is the smoke-like clouds that it creates.

Commercial humidifiers

The most common humidifiers are those found in a normal house, and there is so much variety that no single design stands out from the others. Many of them are wall-mounted as this can cause water vapor to start and drift down in the room, but others can be screwed directly to the ceiling. The amount of steam they produce is relatively small compared to industrial models, so you can usually only see the clouds when it is a very dry day, but they can make a very noticeable difference to an enclosed space.

These humidifiers not only ensure a comfortable home, but are also designed to help keep your skin from drying out and ward off certain diseases or weather-related conditions. While not so important in wet weather, it can make a big difference in summer or on dry winter days.

Medical humidifiers

Humidifiers are also used in numerous medical procedures and tools, including ventilators and sterilization systems. Low humidity prevents viruses and germs from spreading, while higher humidity makes patients feel comfortable and reduces pressure on dry skin. Because they can improve the breathing of people in the same room, they are used in addition to other therapy methods to help asthmatics or patients with severe allergies.

What types of humidifiers are there?

There are several different types of humidifiers you could end up buying, and they all work in slightly different ways. Vaporizers are the cheapest: an average vaporizer contains evaporating water and slowly filters the vapor into the air. It is generally limited to a smaller area, such as a single room, and not an entire house. Steam vaporizers, on the other hand, use electricity to produce violently large amounts of steam that act like a stronger vaporizer.

Impellers are another extremely common type, where a rotating disc throws tiny drops of water into the air, causing them to wear out faster but be safe to use near children. Ultrasonic mist humidifiers are similarly safe and use vibrations instead of rotating parts.

Though not seen often, larger buildings often use central humidifiers that work like a central heating system by evenly distributing the moisture in every room. In situations where there is too much humidity, you can also use a dehumidifier to extract some of it.

How do humidifiers work?

Despite all these different types, humidifiers have one simple goal: to add more water vapor to the air. Regardless of how you do it, they produce steam and / or steam that mixes with the air, changes the average humidity, and usually lowers the temperature slightly. They all have their own quirks and differences, for example some need to be powered or connected to the water supply, but the end result is usually the same for all types.

The details of how to operate, refill and supply a humidifier depend on the design and the manufacturer’s manual. However, choosing a good place can be difficult. Some types work better at height while others are best used near the ground, and others may have special settings for different locations and weather conditions.
