What Is a Basement Dehumidifier?
A basement dehumidifier is a specialized HVAC appliance designed to remove excess moisture from below-grade spaces. Bryant's DEHXX Preferred™ Series whole-home dehumidifier is available in two capacities—up to 80 or 100 pints of moisture removal per day—and can integrate with your existing HVAC system or operate as a standalone installation. The DEHXX is ENERGY STAR® Most Efficient 2024 recognized and offers automated humidity control. By integrating directly with your existing HVAC ductwork, a Bryant dehumidifier can help maintain indoor humidity between 30% and 50% to help control excess moisture, musty odors, and conditions that can contribute to mold growth.
Why is humidity control essential for basements?
Controlling basement humidity is essential to protect your home's structural integrity and improve indoor air quality. Basements are naturally prone to dampness due to cooler temperatures and their proximity to the ground, which can lead to warped wood, peeling paint, and the proliferation of mold and mildew.
Investing in a whole-home dehumidifier does more than just dry out the air. Bryant whole-home dehumidifiers integrate with central heating and cooling systems to provide consistent moisture removal, while the DEHXX can also be installed as a standalone system when appropriate. This can help make your basement a more comfortable, usable extension of your living space rather than a damp storage area. Learn more about the importance of humidity control.
How Does a Basement Dehumidifier Work?
A Bryant whole-home dehumidifier draws in humid indoor air and uses an independent refrigeration system with a blower, coil and compressor to remove moisture before returning drier air to the home. The collected moisture is drained away rather than requiring a homeowner to repeatedly empty a water bucket.
This continuous cycle provides three distinct advantages over standard portable units:
- Continuous Drainage: Bryant whole-home systems are designed to drain collected moisture automatically, eliminating the need to empty a portable unit's water bucket.
- Whole-Home Circulation: By connecting to your HVAC system, a Bryant whole-home dehumidifier can distribute dehumidified air throughout the connected system rather than treating only one area. Bryant DEHXX models are also zoning capable for targeted humidity control.
- Energy Efficiency: The Bryant DEHXX is recognized as ENERGY STAR® Most Efficient 2024, and its dedicated dehumidification system can remove moisture without requiring the air conditioner to provide all of the home's dehumidification. Bryant notes that reducing indoor humidity can allow homeowners to feel comfortable at a higher thermostat setting during humid weather.

How to Choose the Right Basement Dehumidifier
To choose the right basement dehumidifier, evaluate your home's square footage, current moisture levels, and long-term energy goals. A whole-home system is better suited for homeowners seeking reliable, long-term comfort, while portable units work best only for temporary, localized moisture issues.
Bryant Basement Sizing Guide
Bryant's DEHXX is available in two moisture-removal capacities. Use the following guide as a starting point, then have a Bryant dealer evaluate your home's size, moisture conditions and HVAC configuration before selecting a model.
| Bryant DEHXX Model | Moisture Removal Capacity | Bryant's Published Application |
| DEHXXCDA080 | Up to 80 pints/day | Small- to mid-size homes, condos, townhomes, crawlspaces, basements and attics |
| DEHXXCDA110 | Up to 100 pints/day | Mid-size to large homes, crawlspaces, basements and attics |
Bryant does not publish a single square-footage formula for selecting between these models. A Bryant dealer can account for basement conditions, home size, moisture levels and installation configuration when determining the appropriate capacity.
Assess Capacity and Sizing
Proper sizing is critical for reliable performance. An undersized unit may struggle to control humidity, while an oversized unit may not operate as intended. Bryant's DEHXX models remove up to 80 or 100 pints of moisture per day, with the appropriate capacity depending on the home's size and moisture conditions. Bryant dealers can assess your basement and recommend a unit with the appropriate pint-per-day capacity.
Prioritize Energy Efficiency
For homeowners focused on long-term value, energy efficiency is a key decision factor. The Bryant DEHXX is recognized as ENERGY STAR® Most Efficient 2024. Bryant also designed the DEHXX with automated operation based on your comfort preference, helping the system operate according to the humidity level you select.
Look for Smart and Quiet Features
Modern comfort means "set it and forget it" convenience. The Bryant DEHXX includes an on-board LCD control and can work with compatible Bryant controls.
- Smart Controls: Compatible Bryant controls allow homeowners to manage their preferred humidity level and automate dehumidifier operation.
- Quiet Operation: The DEHXXCDA080 is rated at 45 dBA when ducted and 49 dBA when unducted; the DEHXXCDA110 is rated at 55 dBA ducted and 58 dBA unducted.
- Automatic Humidistats: The DEHXX provides automated operation based on your comfort preference, helping maintain your selected humidity level.
Installation and Maintenance
Proper installation by your local Bryant dealer ensures your dehumidifier is optimized for your specific layout and operates as intended. The Bryant DEHXX is compatible with any furnace or fan coil and can be installed as part of an HVAC system or as a standalone unit. Whether utilizing existing ductwork or setting up a standalone configuration for non-ducted spaces, professional installation can help ensure reliable performance.
Maintenance is straightforward and designed for the homeowner. Routine tasks include checking the filter every one to three months and ensuring the drain line remains clear. The DEHXX includes a MERV 8 filter, and Bryant recommends routine filter maintenance to support proper airflow and performance. Annual professional service can help verify system operation and other components.
Routine maintenance keeps efficiency high. Clean or replace filters every one to three months, check the condensate line quarterly, and vacuum dust around vents. Schedule annual professional service with your local Bryant dealer to verify refrigerant performance, fan operation, and calibration. With these steps, your Bryant whole-home dehumidifier can provide consistent moisture control and long-term comfort.
