Types & When to Use Each
Bypass
Uses furnace blower; simple, budget-friendly. Best for compatible ducted systems.
Fan-Powered
Has its own fan; adds moisture more quickly. Good when static pressure is a concern.
Steam
Most output, precise control. Ideal for large homes or when higher RH is needed.
Sizing & Target Humidity
Most NC homes are comfortable at 35–45% RH in winter. Correct sizing considers square footage, insulation, air leakage, occupancy, and the heating equipment’s runtime.
Maintenance & Ownership Costs
- Bypass/Fan-Powered: replace pads annually; clean housings
- Steam: periodic scale removal & water quality considerations
- Have us check operation during your fall/winter tune-up
