#dehumidifiers

Anyone who has a basement knows that they’ve got a tendency to be humid and a breeding ground for mold and mildew. You’ve got to figure out a way to keep the dampness under control, especially if you use your basement for storage. One solution is to find the most efficient dehumidifier for a basement and install it. Whether you’re a DIYer, a homeowner, or a professional cleaner, you may be wondering how to find the best dehumidifiers. Keep reading to learn how dehumidifiers work, what the best models are, and how to select the best dehumidifiers for a basement. Understanding Dehumidifiers and How to Know What to Choose Let’s start with why you might need a dehumidifier in the first place. Dehumidifiers can prevent the growth of mold and mildew, both of which can cause health problems. Two-thirds of all people in the United States have experienced mold in their homes. Having a mold issue can reduce the value of your home by up to $99,000. One-fifth of all asthma cases in the US may be caused by mold. These numbers show how mold issues can impact your health and your wallet, and why having an air purifier or air conditioner may not be enough. What Do Dehumidifiers Do? The simplest way to describe what dehumidifiers do is that they pull moisture from the air. Most are composed of five basic parts. Fan Compressor Cooling coils Reservoir  Reheater Air gets pulled into the dehumidifier and cooled and compressed to remove moisture. The moisture goes into the reservoir, and then the air is reheated and released back into the room. How to Know Which Dehumidifier to Choose Here are some questions to ask yourself before you go shopping for a dehumidifier. How much humidity is in my home? (More on that in the next section.) How large is my home? Will I need to run the dehumidifier all the time? How much do I want to spend? These questions will help you narrow your choice of dehumidifiers. How to Measure Indoor Humidity Levels One of the most important questions to ask is how humid your home is to begin with. It’s easy to figure out. You can head to your hardware store and purchase a hygrometer to give you the percentage of humidity. If you have two thermometers on hand, here are the steps to measure humidity levels in your house without a hygrometer. Step 1: Take two standard glass thermometers. Leave one as it is, and wrap the base of the other with a wet cloth. Step 2: Place both thermometers in front of a fan. Leave them there for five minutes. Step 3: At the end of five minutes, check the temperatures and subtract the dry bulb temperature from the wet bulb temperature. Use the table on this page to identify your humidity level. Watch the video below to see the dry and wet bulb thermometer method. Types of Dehumidifiers There are several types of dehumidifiers to consider.

Should I go with a commercial/industrial grade dehumidifier? The truth is that most homes won’t require a commercial or industrial grade dehumidifier, but some may. Consumer Reports has said that smaller dehumidifiers won’t get the job done in spaces that are 1,200 square feet or larger.2 If you’ve got a large home or live someplace where the humidity is extremely high, then you may benefit from investing in a commercial dehumidifier.

If your comfort is the most important thing, then the real answer is that you should keep the humidity at a level where you’re not uncomfortable. The EPA says that for indoor spaces, the ideal humidity level is between 30% and 50%.3 Are there any side effects from running a dehumidifier all day? While dehumidifying your living space can help with mold and allergens, there are some potential side effects, too. According to Healthline, since dehumidifiers remove moisture from the air, they may dry out your skin, hair, and nasal passages.4 Drinking enough water can offset the effects.

A healthy home leads to a happier and healthier life. Routinely performing general maintenance tasks can keep mold and dust from building up in your home, making you unwell. You don’t want to get home at the end of the day, and the bathroom sink is clogged, and the ceiling is leaking due to overflowing gutters. Instead, you want to come home to a fresh house with purified air and dust-free surfaces.

Achieving comfortable indoor living requires careful attention to moisture balance rather than extremes. When Dehumidifiers and Humidifiers are used thoughtfully together, they create an environment that feels stable, comfortable, and healthy. This balanced approach supports air quality, protects interior spaces, and enhances daily comfort. With proper understanding and use, moisture control becomes a reliable foundation for maintaining pleasant indoor conditions throughout every season.

Anyone who has a basement knows that they’ve got a tendency to be humid and a breeding ground for mold and mildew. You’ve got to figure out a way to keep the dampness under control, especially if you use your basement for storage. One solution is to find the most efficient dehumidifier for a basement and install it. Whether you’re a DIYer, a homeowner, or a professional cleaner, you may be wondering how to find the best dehumidifiers. Keep reading to learn how dehumidifiers work, what the best models are, and how to select the best dehumidifiers for a basement. Understanding Dehumidifiers and How to Know What to Choose Let’s start with why you might need a dehumidifier in the first place. Dehumidifiers can prevent the growth of mold and mildew, both of which can cause health problems. Two-thirds of all people in the United States have experienced mold in their homes. Having a mold issue can reduce the value of your home by up to $99,000. One-fifth of all asthma cases in the US may be caused by mold. These numbers show how mold issues can impact your health and your wallet, and why having an air purifier or air conditioner may not be enough. What Do Dehumidifiers Do? The simplest way to describe what dehumidifiers do is that they pull moisture from the air. Most are composed of five basic parts. Fan Compressor Cooling coils Reservoir  Reheater Air gets pulled into the dehumidifier and cooled and compressed to remove moisture. The moisture goes into the reservoir, and then the air is reheated and released back into the room. How to Know Which Dehumidifier to Choose Here are some questions to ask yourself before you go shopping for a dehumidifier. How much humidity is in my home? (More on that in the next section.) How large is my home? Will I need to run the dehumidifier all the time? How much do I want to spend? These questions will help you narrow your choice of dehumidifiers. How to Measure Indoor Humidity Levels One of the most important questions to ask is how humid your home is to begin with. It’s easy to figure out. You can head to your hardware store and purchase a hygrometer to give you the percentage of humidity. If you have two thermometers on hand, here are the steps to measure humidity levels in your house without a hygrometer. Step 1: Take two standard glass thermometers. Leave one as it is, and wrap the base of the other with a wet cloth. Step 2: Place both thermometers in front of a fan. Leave them there for five minutes. Step 3: At the end of five minutes, check the temperatures and subtract the dry bulb temperature from the wet bulb temperature. Use the table on this page to identify your humidity level. Watch the video below to see the dry and wet bulb thermometer method. Types of Dehumidifiers There are several types of dehumidifiers to consider.

FAQs Do dehumidifiers prevent mold? This is a great question, and the answer is yes, but only to a point. Experts have pointed out that it’s impossible to remove all mold and mold spores from an interior space.1 However, they’ve also said that mold thrives in damp environments, so installing a dehumidifier can make your home a less welcoming place for mold. Should I go with a commercial/industrial grade dehumidifier? The truth is that most homes won’t require a commercial or industrial grade dehumidifier, but some may. Consumer Reports has said that smaller dehumidifiers won’t get the job done in spaces that are 1,200 square feet or larger.2 If you’ve got a large home or live someplace where the humidity is extremely high, then you may benefit from investing in a commercial dehumidifier. What’s the ideal humidity for inside a house? The answer to this question may depend partially on personal preferences and partially on environmental and health concerns. If your comfort is the most important thing, then the real answer is that you should keep the humidity at a level where you’re not uncomfortable. The EPA says that for indoor spaces, the ideal humidity level is between 30% and 50%.3 Are there any side effects from running a dehumidifier all day? While dehumidifying your living space can help with mold and allergens, there are some potential side effects, too. According to Healthline, since dehumidifiers remove moisture from the air, they may dry out your skin, hair, and nasal passages.4 Drinking enough water can offset the effects.
