How to Pick a Dehumidifier - Complete Guide

Dealing with excessive moisture in your home? Struggling with water damage?

A dehumidifier could be the solution you’ve been looking for. Excess humidity can lead to mold growth, musty odors, and even health issues.

In this article, we will guide you through the process of picking the right dehumidifier for your needs, ensuring a comfortable and healthy living environment.

Understanding Dehumidifiers

Before we dive into the factors to consider when choosing a dehumidifier, it’s important to understand how they work. Dehumidifiers are appliances that remove excess moisture from the air, reducing humidity levels. They achieve this by condensing the moisture on cooling coils or absorbing it with a desiccant material.

Using a dehumidifier offers several benefits. Firstly, it helps prevent mold and mildew growth, protecting your home and belongings. Secondly, it reduces musty odors, creating a fresher and more pleasant living environment.

Additionally, dehumidifiers can alleviate respiratory issues caused by high humidity levels. They also aid in drying damp laundry faster and can even help preserve the lifespan of certain items, like books and electronics.

Factors to Consider When Choosing a Dehumidifier

  1. Size and Capacity

The size and capacity of a dehumidifier are crucial factors to consider. You need to determine the square footage of the area you want to dehumidify and choose a dehumidifier with the appropriate capacity to effectively remove excess moisture in such area.

  1. Humidity Control and Settings

Look for a dehumidifier that offers precise humidity control and adjustable settings. This allows you to set and maintain your desired humidity level, ensuring optimal comfort and efficiency. Speaking of…

  1. Energy Efficiency

Energy efficiency is an important consideration, as it impacts both the environment and your electricity bills. Look for dehumidifiers with an Energy Star rating, as they are designed to consume less energy while providing the same level of performance.

  1. Noise Level

Consider the noise level of the dehumidifier, especially if you plan to use it in living spaces or bedrooms. Look for models that operate quietly, allowing you to enjoy a peaceful environment.

  1. Maintenance and Filter Replacement

Check the maintenance requirements of the dehumidifier. Look for models with easy-to-access filters that can be cleaned or replaced without much hassle. Regular maintenance ensures optimal performance and longevity.

  1. Additional Features

Some dehumidifiers come with additional features like built-in timers, auto-defrost functions, or digital displays. Assess these extra features and determine if they align with your needs and preferences.

Different Types of Dehumidifiers

There are various types of dehumidifiers available in the market. Understanding their differences can help you make an informed decision:

  1. Refrigerative Dehumidifiers

Refrigerative dehumidifiers use a cooling coil to condense moisture from the air. They are ideal for most residential settings and offer effective humidity control.

  1. Desiccant Dehumidifiers

Desiccant dehumidifiers use a desiccant material to absorb moisture from the air. They are often more energy-efficient and operate at lower temperatures, making them suitable for colder environments.

  1. Whole-House Dehumidifiers

As the name suggests, whole-house dehumidifiers are designed to dehumidify an entire home. They are typically installed as part of the HVAC system.

  1. Portable Dehumidifiers

Portable dehumidifiers are versatile and can be easily moved from room to room. They are suitable for smaller spaces or areas that require temporary dehumidification, like water-damaged rooms. 

How to Determine the Right Size for Your Space

Determining the right size of dehumidifier for your space is essential for optimal performance.

Follow these steps to calculate the appropriate capacity:

Step 1: Measure the length and width of the room in feet.

Step 2: Multiply the length and width measurements to get the square footage.

Step 3: Consider the moisture level in your area:

  • If the room is slightly damp, multiply the square footage by 1.5.
  • If the room is very damp, multiply the square footage by 2.
  • If the room is wet or has water damage, multiply the square footage by 3.

Step 4: The resulting number is the capacity you should look for in a dehumidifier (in pints).

Step-by-Step Guide to Choosing a Dehumidifier

Now that you have a clear understanding of the factors and types of dehumidifiers, follow this step-by-step guide to choose the right dehumidifier:

  1. Assess Your Needs

Perhaps you have water damage. Do you really need to purchase a dehumidifier? Or can you just hire a water damage restoration company to “dry out” the problem for you?

Weigh in your options. 

  1. Calculate the Room Size

Measure the dimensions of the room and calculate the square footage to determine the capacity required, as outlined above.

  1. Determine the Desired Humidity Level

Decide on the desired humidity level to maintain in your space. This will help you choose a dehumidifier with appropriate control settings.

  1. Research and Compare Models

Conduct thorough research on different dehumidifier models. Consider their features, performance, and customer reviews. Compare their specifications to find the best fit for your needs.

Some of the popular models include Haier 20-Pint Dehumidifier, BLACK+DECKER 30-Pint Dehumidifier, and Honeywell 70-Pint Dehumidifier. 

  1. Read Customer Reviews

Read reviews from customers who have purchased and used the dehumidifiers you are considering. Pay attention to their experiences, pros, and cons to gain valuable insights.

  1. Consider Energy Efficiency

Opt for an energy-efficient dehumidifier to reduce your environmental footprint and save on energy costs in the long run.

  1. Evaluate Noise Levels

If noise is a concern, choose a dehumidifier that operates quietly, especially for bedrooms or living areas.
