Aprilaire 800 Humidifier Toronto — Whole-Home Steam for Big Comfort Gains
Winter air in Toronto can be brutally dry. The Aprilaire 800 Steam Humidifier adds clean moisture directly into your ductwork so every room benefits—protecting people, hardwood floors, cabinetry, musical instruments, and finishes. Its electrode-steam design automatically adapts to your home’s water and delivers serious output for larger or tighter homes.
Why GTA homeowners choose the Aprilaire 800
- High capacity: 11.5–34.6 GPD depending on voltage and amp setting, sized for big homes and tough cold snaps.
- Automatic control: Model 62 digital humidistat + outdoor sensor adjusts RH based on outdoor temperature; can activate your HVAC blower for sampling/maintaining setpoint.
- Whole-home coverage: duct-mounted dispersion tube spreads steam evenly across the airstream for room-to-room comfort.
- Water-friendly: Purified water is not required—electrode technology needs natural minerals for conductivity (no special filtration needed).
- Low seasonal service: replace the steam canister (Model 80 or 80LC) about once per heating season; periodic drain/hoses check.
How it works
The 800 boils water inside a sealed canister using two electrodes. Steam flows through a high-temp hose into a dispersion tube in your supply duct. Integrated fill and drain valves manage water quality and temper drain water. The included Model 62 Automatic Digital Control monitors indoor RH (and outdoor temperature) and runs the humidifier only when needed.

Is Aprilaire 800 right for me?
Choose the 800 if you have a larger home, short furnace run times, humidity-sensitive finishes (hardwood, millwork), or need steady output regardless of supply-air temperature. If you don’t have ducts in the target area, ask about the fan-pack option (Model 865 system) which disperses steam directly into a space.
