A humidifier-dehumidifier combo would be the perfect solution to manage humidity levels around the home.

Are you struggling to maintain a comfortable level of humidity in your home or office? Are you considering a humidifier-dehumidifier combo?

A humidifier-dehumidifier combo would be the ideal solution to handle air moisture – if it existed.

Some people think that a combo product is impossible, but there are several options available on the market today. Let’s explore the world of humidifier dehumidifier combos and discuss their features and benefits, so you can decide if they’re worth the investment for your unique needs.

The Truth About Humidifier Dehumidifier Combo Units

The market does not have a wide range of dedicated humidifier-dehumidifier combo units that perform both functions within a single unit. Humidifiers and dehumidifiers incorporate distinct technologies to either add moisture to the air or remove it.

There are devices that offer both humidification and dehumidification capabilities within the same unit, but these typically function as standalone units that are joined together, rather than the one unit doing everything. For example, some advanced HVAC systems might incorporate both humidification and dehumidification features to control indoor humidity levels. These systems can switch modes based on the sensed humidity levels.

If you need to add and remove humidity in the same space, then separate humidifier and dehumidifier units may be your best option. However, as technology and product offerings evolve, it’s worth regularly checking for any new product releases.

Understanding Humidity Control

Humidity and Its Effects on Indoor Environments

Humidity indicates the moisture content in the air and significantly influences indoor comfort and overall well-being. If the air gets too humid, it can create a muggy and uncomfortable feeling. Conversely, low humidity levels can cause dry skin, respiratory passage irritation, and increase the risk of respiratory infections. In addition, incorrect humidity levels can promote mold growth, harm wooden furniture, and make paint peel in indoor spaces.

Differentiating Between Humidifiers and Dehumidifiers

Humidifiers and dehumidifiers are devices designed to regulate indoor humidity levels, but they serve opposite purposes.

  • Humidifiers add moisture to the air, increasing humidity levels in environments where the air is too dry. This is particularly beneficial during cold winter months when indoor heating systems can lead to dry air.
  • Dehumidifiers, on the other hand, reduce moisture in the air. This makes them essential when humidity levels are excessively high, which can lead to discomfort and potential mold growth.

Benefits of Using a Combination Device

Although you might not commonly find dedicated humidifier-dehumidifier combo units, the idea of merging these two devices into one is interesting. This combination device could offer the best of both worlds by allowing users to tweak humidity levels as per their requirements. For example, in transitional seasons when humidity levels may vary, the combo device could automatically switch between humidification and dehumidification modes to maintain ideal indoor conditions.

However, it’s important to note that creating an effective and efficient combo unit presents technical challenges due to the contrasting mechanisms of adding and removing moisture from the air. Manufacturers would need to balance these functions without compromising performance or causing operational issues. In the absence of dedicated combo units, homeowners seeking both humidity control functions may need to consider using separate humidifiers and dehumidifiers strategically placed in different areas of their living spaces.

In the following sections, we will delve into the specific factors to consider when selecting individual humidifiers and dehumidifiers, along with affordable options available in the market for each. While a combination device might be an exciting idea, it’s crucial to make informed decisions to achieve the desired indoor comfort and health benefits.

Humidity Control Options

There are four main appliances available to combat the ongoing battle with humidity control. They each serve a primary function and are essential for living in any climate that is not at the optimum humidity level, especially for any home that is humid. They are:

  • Humidifiers
  • Air Purifier Humidifiers
  • Dehumidifiers
  • Extractor Fans

Below we’ll look at how each helps to control your home’s humidity.

A humidifier adds moisture to air in a room or living space. You’d use a humidifier more often in winter when the air is usually drier than during the rest of the year.

Symptoms of dry air include :

  • coughing,
  • sneezing,
  • dryness of the throat, and
  • dry, flaky skin.

Humidifiers come in a few different styles:

  1. Evaporative Humidifiers: These humidifiers use a fan to blow air through a wet wick or filter. The air absorbs moisture from the wick and circulates it into the room. They provide cool mist and are generally safe for all ages. They are often more budget-friendly and don’t require as much maintenance as some other types.
  2. Ultrasonic Humidifiers: Ultrasonic humidifiers produce mist through ultrasonic vibrations that break water into tiny droplets. Depending on the model, they provide either cool or warm mist. They generally operate more quietly and consume less energy, although they might need cleaning more often to avoid bacterial growth.
  3. Steam Vaporizers: Steam vaporizers heat water to generate steam, then cool it slightly before releasing it into the air. They produce warm mist which is especially beneficial for easing respiratory symptoms. However, they use more energy and can feel hot to touch, making them better suited for use around older children and adults.
  4. Cool Mist Humidifiers: Cool mist humidifiers, on the other hand, encompass both evaporative and ultrasonic humidifiers, producing a cool mist. They are great for adding moisture to the air without raising the room temperature. Cool mist humidifiers are generally safe for use around children and pets.
  5. Warm Mist Humidifiers: Warm mist humidifiers, such as steam vaporizers, produce a warm mist by heating water. The warmth can help ease congestion and respiratory issues. However, they can be a bit riskier around children due to the hot water and steam they produce.

Air Purifier Humidifiers

An air purifier humidifier has one extra feature when compared to the average humidifier. It removes many particles trapped in the air including pollen, dust, pet dander, mold, and odor.

The way in which this works is through a simple filtering system. By using a removable and washable filter, the unit traps and contains these particles for disposal.


Dehumidifiers, as you probably guessed, actively decrease the moisture levels in the air. Air with a high moisture content can lead to corrosion and rust. Mold and mildew formation, which pose health risks, can also result.

Dehumidifiers generally fall into three main categories:

  1. Refrigerative (Compressor) Dehumidifiers: function similar to air conditioners, utilizing a refrigeration cycle to remove moisture from the air. Here’s how they work:
    • A fan draws in moist air.
    • The air passes over cold coils, causing the moisture to condense into water droplets.
    • The water droplets collect in a reservoir, while the drier air is reheated and released back into the room.
    • Some models also include a humidistat to regulate the humidity level.
  2. Desiccant Dehumidifiers: These dehumidifiers use a desiccant material (a substance that absorbs moisture) to remove humidity from the air. The process involves:
    • The fan draws in air.
    • The air passes over the desiccant material, which absorbs moisture.
    • The moist air is then expelled outdoors or passed through a reheating process before being released back into the room.
    • Desiccant dehumidifiers are particularly effective in low-temperature environments and often operate quietly.
  3. Whole-House Dehumidifiers: These dehumidifiers are integrated into HVAC systems and are designed to control humidity levels throughout an entire house. They work by:
    • Drawing in air from various parts of the house.
    • Passing the air over cooling coils to condense moisture.
    • Reheating the air to its original temperature before distributing it back through the HVAC system.
    • This approach ensures consistent and balanced humidity levels throughout the home.

It’s important to note that different dehumidifiers are better suited for specific situations. Refrigerative dehumidifiers are commonly used for general household use, while desiccant dehumidifiers excel in colder conditions. Whole-house dehumidifiers are ideal for maintaining consistent humidity levels across larger spaces.

There are also many different applications that dehumidifiers are designed for, including:

Each design fits a specific use and works to keep humidity below 60 percent – the level where corrosion can start to form.

Extractor Fans

Extractor fans simply suck out the humid air so that it does not have a chance to cause problems with condensation, mold, and mildew buildup. These are particularly useful in areas with concentrated humidity problems, such as bathrooms and stovetops.

Here are the main types of extractor fans:

  1. Wall-Mounted Extractor Fans: These fans are installed in external walls and are commonly used in bathrooms and kitchens. They expel air directly to the outside.
  2. Ceiling-Mounted Extractor Fans: These fans are installed in the ceiling and are suitable for spaces where wall installation is not feasible. They are often used in bathrooms and large kitchens.
  3. Window Extractor Fans: These fans are designed to fit in windows and provide ventilation in areas where other types of installation might be challenging.

Each type of extractor fan serves the purpose of expelling stale air, odors, and excess moisture from indoor spaces, contributing to better indoor air quality and humidity control.

Factors For Humidifier or Dehumidifier Selection

Size and Capacity According

You must select the right size and capacity for your humidifier or dehumidifier to ensure effective performance. The measurement of the unit’s capacity often involves the volume of moisture it can add or remove from the air in a specific period, typically in gallons per day (GPD) or pints per day (PPD). If you choose a unit that is too small for your space, it may not control humidity adequately, while selecting an excessively large unit can result in wasting money or too much energy consumption. Measure the square footage of the area you intend to use the device in and refer to the manufacturer’s recommendations for the appropriate capacity.

Humidification or Dehumidification Technology

Different technologies are used in humidifiers and dehumidifiers to achieve their respective functions.

For humidifiers, common technologies include evaporative humidification, ultrasonic humidification, and steam vaporization. Each has pros and cons, including noise level, maintenance needs, and the size of water tank.

Refrigerative dehumidifiers work best in larger spaces and higher humidity levels. Desiccant dehumidifiers perform well in lower temperatures and usually produce less noise.

Additional Features and Settings

  • Humidistat: This built-in device measures humidity levels and automatically adjust the humidifier or dehumidifier to maintain a set humidity range. Units with humidistats provide a convenient way to achieve consistent and comfortable indoor conditions.
  • Hygrometer: These display the current humidity levels.
  • Programmable Controls: Some advanced units come with programmable controls that allow you to set specific humidity levels for different times of the day. This feature is particularly useful for achieving optimal comfort while saving energy during periods when you might not need as much humidity control.
  • Auto-Shutoff and Timer Functions: An auto-shutoff feature turns off the unit when a desired humidity level is reached or when the water reservoir is empty, preventing over-humidification or over-dehumidification. Timer functions let you schedule when the device operates, helping you manage energy usage and humidity levels according to your daily routine.

As you compare different products, pay attention to these features and how they align with your preferences and lifestyle.

Humidifier and Dehumidifier Options

Unfortunately, humidifier-dehumidifier combo options that are combined into one unit are rare. But this may be for a few (good) reasons:

  • Typically, most people only want one or the other
  • It increases the size of the unit, as well as the cost and complexity
  • For the combo units that do exist, the manufacturers have typically just combined the 2 individual units into one. So if one unit stops working, it means that you still have to keep the broken unit so that you can use the part that still works, or throw out the lot and replace it all (remember the combo VCR / DVD players – if one player broke, you had to either keep the whole unit and buy just the unit that stopped working, or throw out the whole lot which meant throwing out the 1/2 that did work, and replace it all)
  • It can be better to purchase 2 individual units because the capacity requirements are different for each application

With all that in mind, here are some of the different Humidifier and Dehumidifier options on the market at the moment:
