AlorAir Sentinel WHD150/WHD200 Whole House Dehumidifier

Commercial-Grade Whole-House Dehumidification The AlorAir Sentinel WHD150 and WHD200 tie directly into your ductwork to dehumidify large homes and commercial spaces from one central unit. Choose the WHD150 for up to 3,500 sq. ft. (140 pints AHAM), or the WHD200 for up to 4,500 sq. ft. (165 pints AHAM) — both professional-grade and C-ETL certified with dual-stage filtration. DIY Multiple Inlet and Outlet Rotate the inlet and outlet configuration to fit your install — forward air, rear air, or up air — without buying a different unit for a different layout. Energy Efficient — removes moisture across large homes and commercial spaces without spiking your energy bill. Upgraded Fresh Air Function — a fresh air damper brings in outdoor air on demand, plus GPP mode, continuous mode, timer, and power-failure memory. Automatic Defrost — built-in sensors trigger a defrost cycle before coil frost can hurt performance. Diversified Installation — duct to multiple rooms, or run in series/parallel with other ventilation equipment for the largest spaces. 6-Year Limited Warranty — every unit is ETL-compliant and backed by AlorAir's support team. Gravity or Pump Drainage — Your Choice Run a gravity drain line to a nearby floor drain, or add a condensate pump (sold separately) when gravity draining isn't an option for your install location. Works With Your Existing HVAC Ducting Tie into your HVAC return and supply ducts to dehumidify air as it circulates through the house — no standalone unit taking up floor space in every room.
