When you think about the quality of air in your house, you’re probably more concerned about indoor air decay than moisture levels. But did you know that the quantity of moisture in the air, called relative humidity, can also affect your home and health significantly? Maintaining the right humidity levels is crucial for your comfort and well-being.
Relative humidity indicates how much water is in the air compared to its capacity at a given temperature. The Environmental Protection Agency (EPA) suggests keeping humidity levels around 30% and 50% to prevent issues caused by air that’s too dry or too humid.
Understanding why relative humidity matters, how to adjust humidity levels in your home, and when to consider using a humidifier or dehumidifier can make a big difference in your living environment.
Humidifiers
The two most common kinds of humidifiers are those that produce a cold mist and those that produce a warm mist, often called steam vaporizers.
Both types effectively add moisture to the air, and there’s no significant advantage to one over the other besides personal preference. However, the way they create moisture might influence your choice.
Here’s how cool-mist humidifiers function:
Impeller: The impeller works by releasing small droplets of water into the air after a vibrating plate has mixed the water.
Ultrasonic: A spinning disk uses ultrasonic technology to create droplets of water that resemble steam.
Evaporators: Cool air is able to hydrate objects that are already wet by passing it through an evaporator.
To put it simply, cool-mist humidifiers disperse water vapor into the air by breaking it down into microscopic particles. They may contribute moisture to the air while keeping it chilly since they start and stay cold.
Steam vaporizers, often known as warm-mist humidifiers, usually:
Bring water to a boil using an electric stove.
Produce steam that’s cooled before being released into the air.
People with allergies or asthma may find relief from their symptoms by using steam vaporizers in conjunction with inhalants or essential oils.
Benefits of Humidifiers
Potential advantages of humidifiers include fewer allergy symptoms, less snoring, relief from sinus issues, and relief from dry skin. They could even aid in avoiding or reducing the signs and symptoms of the flu and common cold. Now, let’s explore the research behind the benefits of humidifier use.
1. Help with Allergies
Humidifiers may be useful in relieving dry, itchy throats and runny noses, which are frequent allergy symptoms. They can also help soothe nasal and throat tissues.
2. Help with Snoring
Humidifiers may aid by releasing mucus that obstructs the airway, which may lessen or halt snoring if nasal congestion is a contributing factor.
3. Help with Dry Skin
Many individuals suffer from dry skin, which is often brought on by the dry winter months or by dry air conditioning. By moisturizing the skin, humidifiers may aid by adding moisture to the air.
4. Keep Germs at Bay
Humidifiers don’t directly eradicate pathogenic microorganisms, but they may provide an environment that is less favorable to their existence. For example, studies indicate that influenza virus particles do not multiply as much in humid environments.
5. Improves Sinus Problems
Dry air can irritate nasal passages, which can cause congestion and an increase in mucus production. Humidifiers provide moisture to the air, which reduces irritation and thins mucus.
Dehumidifiers
In contrast to humidifiers, dehumidifiers function by eliminating moisture from the air, assisting in the preservation of dry indoor air. A standard dehumidifier may bring the relative humidity of your indoor air down to a more acceptable range of 30 to 50 percent.
This is how a normal dehumidifier works:
By use of a fan, the dehumidifier extracts heated air, which is then pushed through metal coils that have been lowered in temperature by means of a refrigerant that contains chemicals.
Remember thermal expansion from science class? Well, it’s really the opposite: small water droplets condense out of the air as the air becomes cooler.
Outside the dehumidifier is a tank that collects the condensed water droplets.
A fan-powered tube returns the cooled, dehumidified air to your home environment.
Benefits of Dehumidifiers
There are several benefits to having a dehumidifier in your house or place of business. Here are some reasons for thinking about getting one:
Diminishes Musty Odors – A dehumidifier aids in the removal of musty smells, which are often connected to mold and mildew.
Prevents Mold Development – A dehumidifier works to stop mold from growing on clothes, furniture, drapes, and bedding by lowering moisture levels.
Reduces Dust – Using a dehumidifier helps cut down on airborne dust, which may aggravate allergies in your space. Additionally, it lessens allergens such as mold, mildew, and dust mites, which cuts down on cleaning time.
Reduces Energy expenses
By improving the efficiency of HVAC systems, using a dehumidifier may reduce energy expenses. Air conditioners have to work harder in humid conditions to remove moisture from the air in addition to cooling it down. This increased workload may cause the equipment to break down earlier than necessary, necessitating expensive repairs or replacement. A dehumidifier may help extend the life of HVAC systems by lowering humidity levels, which can ultimately save you money.
The Difference between a Humidifier and a Dehumidifier
Humidifiers work by adding moisture to dry air, often used during winter when the air becomes dry. On the other hand, dehumidifiers are machines that remove surplus moisture from the air; they are often used in the summer and spring when humidity levels rise.
Indoor humidity levels between 40% and 60% are considered pleasant and can reduce health problems linked to high humidity, according to studies.
A hygrometer is an essential tool for determining the relative humidity of any given room. Keeping your home at the ideal humidity level requires regular adjustments due to the fact that humidity levels might change throughout the year.
When to Choose & Explore Types of Humidifiers
Humidifiers, as stated earlier, usually restore the room’s moisture level. A humidifier is a smart investment if your home’s relative humidity is less than 30%.
Extremely dry indoor air, particularly during the winter, may zap the moisture out of your skin, hair, eyes, and lips. Additionally, breathing in dry air may aggravate existing nasal passage conditions, increasing the likelihood of colds, nosebleeds, and other respiratory infections. On top of that, furniture can bend and shrink in dry air.
It is crucial to get a humidifier in order to avert the aggravation of any of these issues upon discovery. You can use a humidifier to prevent dry skin, ease a scratchy throat, lessen the severity of headaches and coughing, and moisturize your nasal passages.
Before purchasing a humidifier, it’s important to understand the different types available.
1. Bypass Humidifiers
These humidifiers usually have a direct connection to HVAC systems. They function by mixing warm air from the heat ducts with water to create moisture in the space. For the most part, these humidifiers are simple, affordable, and efficient in resolving low humidity problems.
2. Power Humidifiers
A powered humidifier is quite similar to a bypass humidifier, with the exception that the latter does not have a fan. You can make it seem like the air conditioner is on full blast without turning on these fans.
3. Steam Humidifiers
In order to add moisture to dry air, steam humidifiers employ in-built heating components, which are different from conventional humidifiers. This gives you more freedom as steam humidifiers don’t need to be part of your HVAC system to work. Steam humidifiers are thus the most adaptable option for your house.
When to Choose & Explore Types of Dehumidifier
If you find that the humidity in your house is more than 60%, installing a dehumidifier is strongly recommended. It can be extremely uncomfortable and challenging for your body to cool off when there is too much humidity.
Additionally, high humidity fosters the ideal conditions for the growth of mold and dust mites. Furthermore, excessive wetness may attract termites and other bugs and harm your furnishings.
In particular, installing a dehumidifier can help maintain proper humidity levels when your HVAC system isn’t able to handle the issue. Depending on your requirements and preferences, there are two primary methods to add a dehumidifier to your house: either installing it as a separate unit or integrating it into your HVAC system.
By serving as ventilators, some dehumidifiers can improve the general quality of the air within. They can filter out allergens, lessen the smell of mold and mildew, and make sure that your home’s damp areas dry up before mold and mildew can form.
There are several kinds of dehumidifiers that you may get for your house, such as:
1. Heat Pump Dehumidifiers
To remove excess moisture from the air, these dehumidifiers usually employ exchange coils, blowers, and heat pumps. The air is drawn in by a fan and travels across cold coils. This causes the moisture in the air to condense and be collected.
2. Dehumidifying Ventilators
An exhaust fan is used by these dehumidifiers to force humid air outside. They are often used by people in attics, basements, and crawlspaces.
3. Chemical Absorbent Dehumidifiers
Often referred to as desiccant dehumidifiers, these appliances work by absorbing excess moisture using materials such as silica gel. They’re especially advised for places with very high humidity and low temperatures.
Humidifier-Dehumidifier Combo
Do you intend to install a dehumidifier and a humidifier in your house? Even while it might appear like a fantastic idea, you may not get the desired outcome. That’s because a combination unit can only effectively serve one purpose: either adding moisture or removing it.
This might lead to unnecessary expenditure without delivering the promised advantages. If you want the optimum results, choose a humidifier or dehumidifier—ideally a programmed one.
A programmable device can maintain your desired humidity levels whenever you need it to. If you want to adjust the humidity in the opposite direction, you can simply switch off the device and let the natural conditions take over.
Which is better a humidifier or dehumidifier?
If your home or a room feels humid and the humidity level is above 60%, you might need a dehumidifier. On the other hand, if it feels hot, stuffy, and dry, and the humidity level is below 30%, a humidifier could help add moisture to the air.
If you’re worried about high humidity, using a dehumidifier might be the way to go. However, if low humidity is a concern, using a humidifier could be helpful.
Remember, it’s crucial to monitor your humidifier use. If you see water collecting on surfaces or notice mold growing, stop using the humidifier and adjust the settings.
FAQ
Use a dehumidifier to regulate humidity levels in the summer, spring, and early autumn, but to protect it from damage in the winter, disconnect it and put it away.
You can check this using a hygrometer, which is an inexpensive device that accurately measures the humidity in your room. The ideal relative humidity is around 50%. If it goes above 60%, it’s probably time to consider getting a dehumidifier.
First of all, it may lead to more power usage, which can result in higher utility costs. Furthermore, there are dehumidifiers that are loud, which can be unsettling, especially at night. Another thing to consider is maintenance; in order to continue operating at their best, dehumidifiers need regular cleaning and maintenance on a regular basis. A dehumidifier can also harbor mold if you fail to maintain it correctly, which could be dangerous to your health.
Dehumidifiers reduce allergens in the air, such as mold, dust mites, and pollen, helping lessen allergy symptoms. They improve the quality of the air by lowering air moisture and inhibiting the formation of mold. They may make breathing easier and keep pests away, but they are not an asthma cure. Moreover, they also lessen the need for air conditioning in humid environments.
Dehumidifiers remove dust from the air, reducing the likelihood of itchy skin. However, they can also make the skin dry and flaky by withdrawing the moisture from the air.
