Why it's worth it

Its continuous-sensor auto-defrost system prevents coil icing and maintains operation in conditions that shut down lesser units — the same reason professional water damage restoration companies use ALORAIR equipment.

From our review of 11 basement dehumidifiers, by David Sinclair, Managing Editor

What we like

  • +Advanced auto-defrost with continuous built-in temperature sensors — designed for cold basement operation
  • +113-pint capacity at saturation conditions; 53 pints at AHAM standard testing
  • +Metal outer casing for commercial-grade durability in demanding environments
  • +MERV-1 filter protects internal components from dust in unfinished spaces

What to know

  • –At $587.48, a significant investment for a portable unit
  • –AHAM-rated 53 pints/day under standard conditions — the 113-pint spec is at saturation
  • –Commercial appearance not suited for finished living spaces
