Humidifiers vs. Dehumidifiers: How they work and what you need

If you’ve found yourself saying “It’s so humid” or “It’s so dry” lately, you’re likely in the market for a humidifier or dehumidifier. Understanding the differences between the two, knowing when to choose one over the other, and determining the best type for your specific needs can help you create a more comfortable home environment.

Humidifiers vs. dehumidifiers: The big (and small) differences

While humidifiers add moisture to the air, dehumidifiers remove it. However, they are not complete opposites. Here’s a closer look at each:

Humidifiers dispense water

Humidifiers require a water tank to disperse moisture into the air. Some advanced models may use a hose feed. There are various mechanisms for dispersing water vapor, with some models also capable of dispensing essential oils.

Dehumidifiers accumulate water

Dehumidifiers draw in moist air, cool it to condense the moisture, collect the water, and release drier air back into the room. Proper water storage or disposal is essential for dehumidifiers.

Humidifiers vs. dehumidifiers design considerations

Key design differences between humidifiers and dehumidifiers include automatic shut-off features, water tank designs, filtration and cleanliness requirements, and noise levels. Consider these factors when choosing the right device for your home.

So, which one do you need?

If your home is humid, a dehumidifier is recommended. For dry air, a humidifier is the solution. If you’re unsure, consider using a hygrometer to measure humidity levels in your home.

Types of humidifiers

Common types of humidifiers include ultrasonic, evaporative, impeller, and vaporizer models. These devices come in central and portable forms, with portable humidifiers being more common for household use.

Types of dehumidifiers

Dehumidifiers come in various sizes and designs, with small units suitable for bedrooms and larger, more powerful models ideal for basements. Consider your specific needs when choosing a dehumidifier.
