A dehumidifier can reduce the relative humidity in your home to below 50 percent, which helps prevent the growth of dust mites, mildew, and mold. Lower humidity levels can also reduce allergens, improve air quality, and make your living spaces more comfortable.
Do You Need a Dehumidifier?
First, assess whether you need a dehumidifier by looking for these common signs of high humidity in your home:
- Condensation on windows
- Mildew spots on walls
- A musty smell in certain rooms
- Watermarks in the basement
- Rotting wood beams or floors
- Peeling wallpaper
If you notice any of these issues, excessive humidity may be present, especially in areas like basements, bathrooms, kitchens, and attics, which are more prone to moisture buildup.
Choosing the Right Type of Dehumidifier
There are three main types of dehumidifiers, and the right choice depends on your specific needs:
Thermo-electric Dehumidifiers - Ideal for smaller spaces or moderate humidity control.
Compressor Dehumidifiers - Better suited for larger spaces and typically more energy-efficient than desiccant models, making them a cost-effective option for home use.
Desiccant Dehumidifiers - Designed for colder environments (temperatures below 2°C), these models aren’t typically recommended for standard home use.
For most home applications, a compressor dehumidifier is usually the best fit.
Determining the Right Size Dehumidifier
To choose the correct size, consider the square footage of the area you want to dehumidify and the level of moisture:
- Small– For rooms up to 600 sq. ft.; removes less than 30 pints/day.
- Medium– For 600-800 sq. ft.; removes 30-40 pints/day.
- Large– For 800-1,200 sq. ft. or high moisture areas; removes 40+ pints/day.
Additional Features to Consider
Beyond capacity, consider additional features that may add convenience, such as a timer, sleep mode, or remote control.
Finding the Right Dehumidifier for Your Budget
Finally, choose the best dehumidifier that fits your budget while meeting your space, capacity, and feature requirements. This careful selection will help you create a healthier, more comfortable living environment.
