Our take on the AlorAir Sentinel WHD 200 Commercial Grade Whole House Dehumidifier

The AlorAir Sentinel WHD 200 is a commercial-grade whole-house dehumidifier rated at 165 pints per day at AHAM conditions and 140 pints at DOE whole-house conditions, sized for spaces up to 4,500 square feet. It runs on standard 115V power, uses R32 refrigerant, and offers ducted mounting for whole-house, crawlspace, basement and light commercial use. Its 65 dBA sound level and 187 lb weight put it in the installed-equipment class rather than the portable one, so it suits crawlspaces, basements and mechanical rooms where it can be ducted and left in place. Against smaller residential units it removes far more moisture per day and accepts ducting; against larger commercial units it gives up capacity but runs on ordinary household current.

Questions and answers

How much moisture does the WHD 200 remove?
It is rated at 165 pints per day at AHAM conditions (80°F, 60% RH) and 140 pints per day at DOE whole-house conditions (73°F, 60% RH). That capacity is meant for spaces up to about 4,500 square feet.
Can it be ducted into my HVAC system?
Yes. AlorAir lists multiple duct mounting options, and the unit is designed for whole-house, crawlspace, basement and commercial ducted installs. Plan the duct layout and drain before placing it.
What power does it need?
It runs on 115V at 8.5 amps, so a standard household circuit works. It does not need a 230V line like some larger commercial dehumidifiers.
How loud is it?
The listed sound pressure level is 65 dBA. That is fine in a crawlspace or mechanical room but noticeable if the unit sits near living space.
What filters does it use?
It takes a MERV-1 filter and a MERV-10 filter. The MERV-10 option captures finer dust than the standard filter.
Does it have a built-in condensate pump?
The listed specifications do not include a built-in pump, so plan gravity drainage or add an external condensate pump for a crawlspace or basement install.
