Whole House Dehumidifiers

Whole house dehumidifiers that tie into the home's ductwork and treat every room the air handler serves, rather than drying one space at a time. Ebac units cover 24 to 150 pints per day, inline or wall-mounted, on 110–115V or 220–230V circuits.

Whole House Dehumidifiers for Ducted, Whole-Building Humidity Control

What makes a dehumidifier a whole house unit?

A whole house dehumidifier connects to the building's duct system, so dried air reaches every room the air handler already serves. A portable dries the room it stands in and leaves the rest of the house at whatever humidity it was.

Two things follow from that. The equipment sits in a mechanical room, basement, or crawl space instead of taking up floor area somewhere finished, and humidity holds at one setpoint across the structure rather than in pockets around wherever a portable happens to be plugged in. Maintenance gets simpler too: one filter, one drain. The EPA puts the target band for indoor relative humidity at 30 to 50 percent, and below 60 percent in all cases.

How to size a whole house dehumidifier

Size on the building's moisture load and the air handler's airflow, not the room count. Match the unit's rated CFM to the duct system it is joining, then pick capacity from the load.

The Ebac range here runs from 24 to 150 pints per day. The CD30-S and CD30-SE (24 PPD) suit small zoned ductwork. The CD60, CD85, and CD100 cover 60 to 90 PPD, which handles most full-home ducted installs. The K100E and K100H (97 PPD, 700 CFM) and the CD200 (138 PPD, 664 CFM) are built for higher-airflow systems, with WiFi monitoring on the K100E. The PD120 (110 PPD, 261 CFM) and PD150-D (145 PPD) take heavier commercial loads. The RM4500 and RM4500-H reach 150 PPD, the second with WiFi and smartphone monitoring. Every unit here is ducted; the WM80 and WM150-D are the wall-mounted versions of that.

What to check before you order

Four site conditions decide whether the install goes smoothly, and getting them wrong is the usual reason a unit arrives and cannot be commissioned.

Start with electrical service, because this range splits across two supplies. The CD60, CD85, CD100, CD100E, CS60, RM40, RM40P, RM40-SH, K100H, WM80, and RM4500 are listed at 110–115V. The AD850E, CD200, K100P, PD150-D, WM150-D, and Freestar are listed at 220V or 230V, which usually means bringing in an electrician. Where a listing does not state a voltage, confirm it before you order. Next, confirm the mounting spot has room for plenum connections, filter access, and service. Check the unit's rated external static pressure against your duct system before ordering, since a mismatch shows up as poor airflow after the install, not before. Last, sort out condensate: a gravity drain needs continuous fall to a drain point, and where that does not exist you need a condensate pump.

Most ducted installations are handled by a licensed HVAC contractor. To compare running costs across units, the ENERGY STAR dehumidifier program publishes the efficiency metric these are measured against.

Frequently Asked Questions

What size whole house dehumidifier do I need?
Size on moisture load and air handler CFM rather than square footage alone. Small zoned ductwork is served by the 24 PPD CD30. A typical full home takes the 60 to 90 PPD CD60 through CD100. Higher-airflow and commercial systems want the 97 to 150 PPD K100, CD200, PD, and RM4500 units. Confirm the unit's rated CFM suits your duct system before ordering.
Are the wall-mounted units still ducted?
Yes. Every unit in this collection is a ducted model, including the WM80 and WM150-D. Wall-mounting describes how the cabinet is fixed, not whether it connects to the duct system.
Will it run on a normal household circuit?
Some will, some will not. The CD60, CD85, CD100, CD100E, CS60, RM40, RM40P, RM40-SH, K100H, WM80, and RM4500 are listed at 110–115V. The AD850E, CD200, K100P, PD150-D, WM150-D, and Freestar are listed at 220V or 230V and normally need an electrician to add the circuit. Where a listing gives no voltage, check before ordering.
What humidity should I set it to?
The EPA recommends keeping indoor relative humidity below 60 percent, ideally between 30 and 50 percent. Going much below that band spends energy for no further benefit, and letting it drift above invites mold growth and damage to building materials.
Can one unit dry a basement and the main floor together?
Yes, if both are on the same duct system and the unit is sized for the combined load. Where the basement is not ducted into that system, it is usually treated separately.
