In the colder winter months, it is important to have a Humidifier in your home. This helps to keep you warm and comfortable, and can also help with your respiratory health. But what is the difference between a Humidifier and a Dehumidifier? And which one should you choose for your home? This article will discuss the pros and cons of both Humidifiers and Dehumidifiers so that you can make an informed decision about which one is right for you!
What does each do?
Humidifier
A Humidifier is a device that increases humidity (moisture) in the air. This can be done for aesthetic reasons, health reasons, or to prevent damage to the home. This device is often used in winter when the air is dry due to indoor heating, or in places with low humidity levels.
Dehumidifier
A Dehumidifier is a device that removes moisture from the air. This can be done for aesthetic reasons, health reasons, or to prevent damage to the home. This device is often used in summer when the air is damp due to outdoor humidity, or in places with high humidity levels.
There are two main types of Dehumidifiers: refrigerants and desiccants. Refrigerant Dehumidifiers work by cooling the air, which causes the water to condense. Desiccant Dehumidifiers work by absorbing moisture from the air.
So, which is better for your home? It depends on your individual needs and the climate you live in. If you live in a climate with high humidity levels, a Dehumidifier may be the better option to keep your home comfortable and prevent damage. If you live in a climate with low humidity levels, a Humidifier may be the better option to keep your skin and sinuses hydrated and healthy [1].
Types of Humidifiers
Humidifiers are produced in various types which include console Humidifiers, whole-house Humidifiers, and portable Humidifiers. You should consider all the types available in the market before settling on one since they all have different features that might be more or less appealing to you.
1. Central Humidifiers
If you have a forced-air heating system in your home, then you already have the ductwork needed to install a central Humidifier. These are also known as whole-house Humidifiers and are by far the most expensive type of Humidifier.
2. Evaporators
Evaporator Humidifiers are placed on top of a radiator. The unit contains a wick that absorbs water from a reservoir and then the heat from the radiator vaporizes the water, which then goes into the air in your home.
3. Impeller Humidifiers
An impeller Humidifier has a rotating disc that flings water against a diffuser, breaking it into tiny droplets which are then sprayed into the air. These devices are much quieter than ultrasonic humidifiers and don’t require as much maintenance.
4. Ultrasonic Humidifiers
This type of Humidifier uses high-frequency vibrations to create a fine mist of water that is then released into the air. These devices are very quiet, making them a good choice for use in a nursery or bedroom. However, they do require regular cleaning to prevent the growth of mold and mildew [2].
5. Vaporizers
A vaporizer Humidifierheats water until it boils and then releases the steam into the air. These Humidifiers can be used with essential oils to create a pleasant-smelling environment, but they require regular cleaning to prevent the growth of bacteria.
6.Steam Humidifiers
A steam Humidifier works by passing water through a heating element which vaporizes it and then releases the steam into the air. These Humidifiers are very effective but can be expensive to operate since they use a lot of electricity.
Types of Dehumidifiers
1. Whole-House Dehumidifiers
Whole-house Dehumidifiers are the most expensive type of Dehumidifier, but they are also the most effective. They are designed to work with your home’s HVAC system to remove humidity from the air throughout your entire house. Whole-house Dehumidifiers are a good choice if you live in a humid climate or if you have a history of allergies or respiratory problems.
2. Desiccant Dehumidifiers
Desiccant Dehumidifiers use a special type of material to absorb moisture from the air. This makes them more effective than other types of Dehumidifiers in very humid climates. They are also less likely to overheat and can be used in enclosed spaces such as closets and cabinets [3].
3. Thermoelectric Dehumidifiers
Thermoelectric Dehumidifiers use electricity to create a cooling effect that removes moisture from the air. They are less effective than other types of Dehumidifiers, but they are more energy-efficient and cost-effective.
4. Refrigerated Coil Dehumidifiers
Refrigerated coil Dehumidifiers work by cooling the air to remove moisture. They are more effective than thermoelectric Dehumidifiers, but they use more energy and are more expensive.
Problems Indicating the Need for a Humidifier or a Dehumidifier
When the humidity in your home falls below 30%, you may start to experience some of the side effects of dry air. These can include:
- Static electricity
- Dry, itchy skin
- Cracked, chapped lips
- Dry sinuses and nosebleeds
- Difficulty breathing
- Excessively dry throat
Conversely, if the humidity in your home rises above 50%, you may start to experience some of the side effects of too much moisture in the air. These can include:
- Musty smells
- Damp-feeling walls or floors
- Condensation on windows or other cold surfaces
- Mold or mildew growth
If you’re experiencing any of these problems, it may be time to invest in a Humidifier or Dehumidifier [4].
How do Humidifiers Work?
Humidifiers work by releasing water vapor into the air. There are several types of Humidifiers, but the most common are ultrasonic, evaporative, and steam vaporizers.
Ultrasonic Humidifiers use high-frequency vibrations to turn water into a fine mist that is then released into the air. Evaporative Humidifiers have a wick that absorbs water from a reservoir and then blows air over it, causing the water to evaporate into the air. Steam vaporizers heat water to create steam, which is then released into the room.
How do Dehumidifiers Work?
Dehumidifiers work by drawing in air from the room and passing it over a cold coil. This causes the water in the air to condense on the coil and drip into a reservoir. The dry air is then blown back into the room.
Additionally, some Dehumidifiers have a built-in heater that can be used to reheat the air as it is being blown back into the room.
Do You Need a Humidifier or a Dehumidifier?
The answer to this question depends on the current humidity levels in your home. You can easily check your home’s humidity levels with a hygrometer, which you can purchase at most hardware stores.
Humidifiers are designed to add moisture to the air, while Dehumidifiers are designed to remove moisture from the air. Dehumidifiers are usually the better choice for homes in humid climates, while Humidifiers are usually the better choice for homes in dry climates.
Both devices are made of similar parts. Each has a fan, filter, and water reservoir. The main difference is that Humidifiers release moisture into the air, while Dehumidifiers remove moisture from the air [5].
The health risks of a dirty Humidifier – and how to avoid them
If you’re using a Humidifier in your home, it’s important to keep it clean. A dirty Humidifier can breed bacteria and spread illness. One study found that Humidifiers may contribute to outbreaks of respiratory illnesses, such as Legionnaires’ disease.
To clean your Humidifier, follow some simple steps:
- Empty the water tank and refill it with fresh water.
- Clean the inside of the tank with a mild bleach solution or white vinegar.
- Rinse the tank thoroughly and dry it completely before refilling it.
- Clean the Humidifier’s filter according to the manufacturer’s instructions.
In addition to cleaning your Humidifier, you should also take steps to prevent mold and bacteria growth in your home. These include:
- Adjust the humidity level to between 30 and 50 percent.
- Keep the temperature in your home above 65 degrees Fahrenheit.
- Avoid using tap water in your Humidifier. Use distilled or filtered water instead.
- Don’t use a Humidifier if you have asthma or other respiratory conditions.
