Buying Guide
A basement dehumidifier regulates the moisture level and prevents mold from growing in one of the darkest, dampest rooms in your home. This buying guide will help you select the best dehumidifier to suit your basement.
- Size:Basement dehumidifiers can be quite large and bulky, and require a significant piece of available floor space. You should measure the size of the dehumidifier and the available space in your basement before making a purchase.
- Range:A basement dehumidifier is categorized by the square footage it can successfully remove moisture from. This helps you choose the right dehumidifier to reach every corner of your basement. Most can dehumidify between 1000 and 4500 square feet at once. If your room has very high humidity, you may want to opt for a model rated for a higher square footage.
- Filter:Most basement dehumidifiers feature a filter that traps dirt, grit, and airborne moisture particles behind it. Over time, these filters can get clogged and become less effective. Some filters can be removed, washed, and put back in place, while others must be replaced once they become too clogged to work.
- Noise level:As they are constantly working in the background, basement dehumidifiers can be fairly noisy. This may become an issue if you work in or regularly visit your basement. Some basement dehumidifiers feature built-in noise suppression technology for quieter operation. The noise level is measured in A-weighted decibels (dBA), which indicates the relative loudness. Under 50 dBA is a relatively quiet machine.
- Other features:Bonus features that can make your basement dehumidifier even more effective and efficient include:
- Auto-drain options
- Odor removal functions
- Automatic shutoff and functions
- Timers
- Additional hose connectors
- Wi-Fi connection capabilities
FAQs
Why does my basement need a dehumidifier?
The basement is the lowest-sitting room in your house, often located fully or partially underground. Because of this, it does not get a lot of light, the air can become damp, and mold can grow quickly. This can ruin any items you have stored in your basement. A dehumidifier keeps the moisture level low and prevents mold from growing.
Do basement dehumidifiers also remove bad smells?
Not all basement dehumidifiers feature an odor removal function, but some do. This may be useful if your basement has previously suffered from an outbreak of mold or mildew, as these can leave behind bad smells. Other unpleasant odors can come from dust or rotting materials.
How do I control and adjust my basement dehumidifier?
Most basement dehumidifiers have a control panel on the unit itself. Some also come with a remote control so you can control them from across the room. Still others will connect to your home Wi-Fi and can be adjusted via an app or smart home assistant.
