Have you ever noticed condensation on your windows, a lingering musty smell, or even mold growing on your walls? If so, there may be an issue with humidity in your home. High humidity is caused by excess water vapor in the air and if the level of humidity reaches 60% inside your home, issues may start to occur affecting your belongings, building, and your health.  

There are various factors that contribute to excess water vapor in the air, from steamy showers to leaky pipes, however the adverse effects can easily be alleviated by using a dehumidifier. A dehumidifier works by passing warm air through refrigerated coils, cooling the air causing it to contract and turn into condensation, leaving cool and dry air to be redistributed into the home.   

Investing in a dehumidifier can cost you anything from $15 to $5000, and while many of the cheaper models may prove to be ineffective, we have scoured the market and found some excellent options all for under $100. If you have more budget then you might be more interested in what is our best whole house dehumidifier which can be used in far large spaces.

It’s important to remember that a dehumidifier will operate at its most effective in a specific-sized room. So while these models may not transform the humidity in your whole home, they can easily tackle humidity in localized hotspots, such as the bathroom, kitchen, or laundry room, and are often small enough to be easily transported and utilized all around the home.  

To help you find the best dehumidifier for your needs, we assessed each machine’s performance and usability, looking into how much moisture can be removed from the air, the room size suitability, operating noise, and energy consumption. If you’re concerned about airborne pollutants in your home as well as humidity levels and you’re still on a budget, take a look at what we think are the best cheap air purifiers which are under $100 but still can do a good job of cleaning your home air.

FAQs About Cheap Dehumidifiers

What are the different types of dehumidifiers? There are three types of dehumidifiers: compressor, desiccant, and thermo-electric. A compressor dehumidifier uses refrigeration to lower the temperature inside the unit. As it pulls in warmer air, the coolness inside causes condensation that will collect in the water tank. That warmer air is then blown back out, but it doesn't have any water in it. This tends to collect a lot of airborne moisture, so the tank needs regular emptying or the connection of a drainage hose. They're louder than most as well. Secondly is a desiccant dehumidifier. This uses an absorbent material to wick away moisture in the air, and since they don't condense moisture the way a compressor unit does, this type of dehumidifier will be more ideal in colder rooms like a garage or a basement. Lastly is the thermo-electric dehumidifier. This type is highly affordable, and they use electric refrigeration to condense and collect airborne moisture. However, this type tends to remove the least amount of moisture in the air within a day, so it can take a bit longer. How do I pick the right size dehumidifier? Determining the right size depends on a few factors. For starters, how big is the room you need to use it in? Also, what are the humidity levels? The size of a dehumidifier is determined by how many pints it's able to remove in a single day. If humidity is a major concern, then you need a dehumidifier powerful enough to handle high moisture environments. A unit that has a 70-pint tank can effectively handle these types of situations in large rooms. If you have a smaller room or less of a humidity problem, then something smaller around 20 pints will be effective. What features should I look out for when buying a dehumidifier? Certain features can make using a dehumidifier more convenient. For instance, a filter indicator light and a bucket full indicator light are beneficial components. These will tell you when it's time to clean a filter and when you need to empty the bucket. Also, consider a hose connection on large capacity dehumidifiers. This will let you run it continuously without having to empty it throughout the day. Some dehumidifiers have an automatic mode with humidity detection. This will auto-detect the humidity levels and turn the unit on or off depending on the room's needs. Other dehumidifiers have multiple fan speeds too so you can run it with more power or less based on what you feel is best. Which Dehumidifier is Best for You? High moisture environments can quickly make your home uncomfortable. It can cause allergen issues, lead to mold and mildew, and even bring out unwanted pests that thrive in moisture-filled environments like spiders and silverfish. That's why dehumidifiers are beneficial. However, dehumidifiers can be expensive, especially the larger ones. That's why we found some top-rated, affordable dehumidifiers that can provide you all the help your home needs without breaking the bank.
