  • Product Overview

    Maintain healthy humidity throughout your home and keep more money in your pocket with the Ultra-Aire XT105H 105-Pint Ventilating Dehumidifier. Considered the world's most energy efficient dehumidifier, this model removes 105 pints of moisture per day and provides comfortable fresh air ventilation - all while using just 4.9 amps and maintaining an energy factor of 4.2 liters per kilowatt hour. These power specifications actually exceed the Energy Star program's standards by 50%.

    This unit is most ideal for average-size homes up to 2,500 square feet. Popular installation options include a basement, crawl space, attic, closet, or mechanical room. Plus, like all Ultra-Aire products, it is proudly made in the USA.

    Exceeds Energy Star Standards

    The Ultra-Aire XT105H Dehumidifier is the only whole house dehumidifier on the market that exceeds Energy Star efficiency standards by 50%. This model uses XT (Extreme Technology) dehumidification to remove 4.2 liters of moisture per kilowatt hour. This rating is equal to double the Energy Star program's minimum energy factor standard for residential dehumidifiers. This essentially means that the XT105H is an incredibly efficient machine that reduces your home's overall humidity while consuming the least possible amount of energy. If you tend to keep a close watch on your home's energy usage, this dehumidifying system is for you.

    Customize the System for Your Needs

    This dehumidifier 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.

    Options for Controlling Your Humidity

    You must purchase a remote dehumidistat controller in order to operate this system. 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.
