What customers say
Consumers highly value the GeneralAire Model 900A for its superior humidification capacity, calling it a reliable workhorse for whole house comfort, especially in winter. Its ability to maintain ideal levels across large areas is a significant advantage over portable units. While performance and long term value are excellent, the main drawback centers on installation. Many users find the setup challenging, often necessitating professional HVAC help, which increases initial expense. Maintenance is manageable, though water panel replacement is noted. Despite installation hurdles, the consensus favors this unit for powerful, consistent humidity control.
