Choosing Between Them
I recommend the Airplus 70-pint unit as the primary choice for anyone dealing with large basement moisture. It provides the most consistent performance for those who need to maintain a dry environment across expansive floor plans. In my view, this machine offers the best value for serious humidity control.
Be aware that your drainage setup will dictate how much maintenance you actually perform. If you intend to run this in a remote corner of your home, ensure you have a floor drain nearby to utilize the continuous gravity drain feature. Failing to plan for the water output is the most common mistake buyers make with high-capacity machines.
