  • Product Overview

    Maintain healthy humidity throughout your home and feel more comfortable indoors with the Ultra-Aire 70H 70-Pint Ventilating Dehumidifier. This whole house dehumidifier integrates into your home's existing HVAC system and ductwork to control humidity throughout your house. This unit also provides whole house ventilation with optional fresh air intake for improved indoor air quality year-round. The Ultra-Aire 70H Dehumidifier is rated to remove 70 pints of damaging moisture per day under AHAM conditions and is designed to handle up to 1,800 square feet. This makes it ideal for smaller homes, condos, and apartments. Popular installation options include a basement, crawl space, attic, closet, or mechanical room. Plus, like all other Ultra-Aire units, this dehumidifier is proudly made in the USA.

    Compact and Efficient, Fits Low-Clearance Spaces

    The Ultra-Aire 70H Dehumidifier is the industry's first ever compact, high-efficiency, whole house ventilating dehumidifier that fits into tight low-clearance spots. Its outer cabinet features a thoughtful design that allows you to convert airflow discharge vertically or horizontally from the unit. This cabinet also allows for dual-side filter access when it's time for maintenance. Both of these features make easier and more flexible installation possible in confined spaces. You'll be able to install this dehumidifier in areas where other dehumidifiers won't fit because of ducting problems, size constraints, or maintenance difficulties.

    The Ultra-Aire 70 H is also a highly efficient unit. Carrying the Energy Star seal, this dehumidifier uses 15% less energy to remove more moisture than similar-sized dehumidifiers. It's also built with a more efficient refrigeration coil, compressor, and fan. The system draws only 5.1 amps of power max while operating, which contributes to an impressive moisture removal energy factor of 2.37 liters per kilowatt hour.

    Customizable Installation to Fit Your Home's Needs

    This dehumidifier can be used as a freestanding dehumidifier or ducted into your home's existing ductwork and HVAC system. Ducting the unit is by far the most popular installation option and the one that will be most effective in maintaining lower humidity and improved air quality throughout your home. The most popular installation options include installing the unit in your basement, crawl space, attic, closet, or a mechanical room. A wide variety of ducting and usage accessories is available to customize a configuration for your home's needs.

    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 ventilation 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. To set up fresh air venting, you'll need to purchase an inlet hood, your preferred ducting accessories, and a remote digital humidity controller like the DEH 3000 or DEH 3000R. 

    *Please note - Ultra-Aire dehumidifiers require professional installation by a qualified contractor. If you are a homeowner, you may first want to consult your contractor on accessories needed for installing the unit in your preferred configuration.

    Options for Setting Your Desired Humidity Level

    • Built-In Dehumidistat - This unit features a built-in dehumidistat that controls your desired humidity. Use this built-in control if you'll be placing the unit in the area you're treating.
    • Optional Remote Dehumidistat - An optional remote dehumidistat—the Ultra-Aire DEH 3000 Digital Controller—is available as well. This controller allows you to set your desired humidity, manage fresh air ventilation, and activate air filtration all from the convenience of your living space. Use this controller if you plan to place the unit in an area outside of the treatment area and/or plan to set up fresh air ventilation.

    Additional Features

    • Condensate Pump Kit Available - If you prefer, you can attach an external condensate pump that can drain condensate upward or across longer distances to a nearby drain.
    • MERV-11 Air Filtration - Captures 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 49 degrees F and includes an auto defrost function to automatically melt frost build-up in chilly conditions.
    • Long Power Cord - A 9-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 70H 70-Pint Ventilating Dehumidifier helps you maintain a healthy humidity level indoors and protect your home investment from damaging conditions that can lead to costly repairs.

    What Customers Love
