  • Product Overview

    Protect your investment and stop problematic humidity in your home with the Ultra-Aire XT205H 205-Pint Ventilating Dehumidifier. Removing a staggering 205 pints of moisture a day, this unit is considered the largest capacity whole house residential dehumidifier on the market.

    This workhorse model was designed for powerful whole house humidity control in large homes up to 5,000 square feet. It works especially well in homes with high ceilings. And it installs in your basement, crawl space, attic, closet, or mechanical room and can be used with a remote humidity controller for your convenience. Easily ductable, this dehumidifier can also be configured to supply fresh air ventilation to all the rooms of your home. Plus, like all Ultra-Aire products, this model is proudly made in the USA.

    Larger Capacity, Same Size

    The Ultra-Aire XT205H Dehumidifier is a powerful large capacity dehumidifier that services large homes up to 5,000 square feet. With such a large capacity, you might expect this model to be double the size of its sister models. But it's not. Remarkably, Ultra-Aire engineers were able to build a more powerful dehumidification system while retaining the size of its smaller XT siblings, the XT105H and XT155H. That means you'll save valuable space when you install this unit and get even more humidity-reducing power.

    Fully Customizable for Your Home's Needs

    The Ultra-Aire XT205 H is designed to integrate into your home's ductwork, creating a full-scale humidity control solution for your home. The most popular installation options for this model include installing the unit in your basement, crawl space, attic, closet, or a mechanical room. A variety of ducting accessories is available to customize a configuration for your home's needs.

    Remote Dehumidistat Options

    You'll need to purchase a remote dehumidistat controller in order to operate this unit. Therma-Stor has a few options available. All of the control units below are wired directly to the Ultra-Aire unit using 24-volt pig tail wiring.

    • Honeywell H46C 1166 Wall-Mounted Humidistat - The Honeywell H46C is a basic analog humidistat you can use to control humidity. It features a manual dial control you'll use to set your desired humidity.
    • Ultra-Aire DEH 3000 Digital Controller - The DEH 3000 is an all-digital controller that allows you to monitor and control humidity, manage fresh air ventilation, and activate air filtration for the unit from your living space.
    • Ultra-Aire DEH3000R Digital Controller - The DEH 3000R is similar to the DEH 3000, but it also features a remote sensor that can be placed up to 100 feet away from the controller. This sensor allows you to control and monitor humidity conditions in a separate area and keep the wall-mounted controller out of sight.

    Accessories for Fresh Air Ventilation

    You may want to configure your Ultra-Aire system to provide fresh air ventilation to your home while it dehumidifies. Doing this brings fresh air into your home. Today’s well-sealed homes can create a build-up of indoor air pollutants, resulting in air that is far more polluted inside than outside.

    Sources of indoor air pollutants include fireplaces, off-gassing furniture and flooring, cleaning supplies, pets, and gas-burning appliances. Fresh air venting creates a safer living environment for you and your family. It's also a popular option for light and natural dehumidifying during drier months when you wouldn't normally run your dehumidifier. For this application, you'll need to purchase an inlet hood, your preferred ducting accessories, and a digital controller like the DEH 3000 or DEH 3000R.

    Additional Features

    • Condensate Pump Kit Available - If you prefer, you can attach an external condensate pump to customize a draining system that can drain condensate upward or across longer distances to a nearby drain.
    • MERV-11 Air Filtration - This model comes standard with a MERV-11 air filter to capture harmful allergens and particles and keep the unit running at peak efficiency.
    • Optional MERV-14 Filter Available - You can add a MERV-14 filter to improve air filtration. The MERV-14 filter is 90-95% efficient in removing particles between 0.3 and 1 micron. When you add this filter, the MERV-11 filter functions as a pre-filter.
    • Low Temperature Operation - Operates in temperatures as low as 56 degrees F and includes an auto defrost function to automatically melt frost build-up in chilly conditions.
    • Long Power Cord - A 10-foot power cord helps make installation options more flexible.
    • Made in the USA - All Ultra-Aire products are made in the USA with quality components by Wisconsin-based Therma-Stor.


    The Ultra-Aire XT205H 205-Pint Ventilating Dehumidifier is a powerful unit that dehumidifies large homes up to 5,000 square feet all while retaining the same cabinet size as Ultra-Aire's smaller capacity XT models.

    What Customers Love

    • More Power, Same Size - The XT205H's cabinet size is exactly the same as that of the XT105H and XT155H models. It's just more powerful.
    • Fully Customizable System - A variety of accessories - including ducting kits, dampers, an external pump kit, a hang kit, added air filtration, and remote humidity controllers - help you fully customize your unit's installation to your preferred specifications.

    Things To Consider
