Design and Size

Ultra-Aire 70H is a compact design. It smoothly connects your HVAC system, doesn’t get out. The dehumidifier has a rectangle form and from one end comes air inlet and from the opposite side comes air outlet. You can remake the air outlet to the top. Dehumidifier provides dual-side filter access. This proceeds easier and more manageable installation possible in limited spaces where other dehumidifiers won’t fit.

Ultra-Aire 70H weight is 55 pounds 25 (kg). Yes, a dehumidifier is heavy but you don’t have to move it. Install it and enjoy how it works.

Dehumidifier size:

  • Height: 12 inches / 30 cm
  • Width: 12 inches / 30 cm
  • Depth: 28 inches / 71 cm


  • Built-In humidistat controls your wanted moisture level.
  • Ultra-Aire DEH 3000 Digital ControllerOptional Remote humidistat controller also is available. With this controller, you can set wanted humidity, control pure air ventilation, and activate air filtration all from the ease of your desired space. There are 2 types of the controller – Ultra-Aire DEH 3000 Digital Controller or DEH 3000R Digital Controller with Remote Sensor. Both controllers have a smooth design and wide, easy-to-read LCD display. The DEH 3000R Digital Controller has a separate sensor that can be installed in an area that is out of place, such as a crawl place while the 3000R Digital Controller can be wall installed in a living space where the Ultra-Aire Dehumidifier purposes can be quickly controlled.
  • Another external feature for this dehumidifier is a condensate pump kit. With an external condensate pump, you can remove condensate upward or across longer distances.
  • MERV-11 air filter is made to catch dangerous allergens and shreds.
  • For more powerful air filtration you can buy a separate MERV-14 filter. This filter is 90-95% effective in eliminating particles within 0.3 and 1-micron size. You can use both air filters together, in this case, MERV-11 works as a pre-filter.
  • Low-Temperature Control allows the dehumidifier to operate in temperatures as low as 49 degrees F and has an auto defrost function to automatically decrease frost build-up in cold conditions.
  • A 9-foot long power cord supports more flexible installation.
  • Made in the USA
  • Energy Star efficient. Read more below under the Maintenance and Upkeep section.

Noise level

Max noise level is 55.3 dB which is ok for this type of dehumidifier. Even more – you will not hear it because it will be installed far from your living room. Don’t have to worry about noise at all.

Maintenance and upkeep

Let’s start with energy consumption. Maximal energy usage for this dehumidifier is 580 watts. While typical 70-pints dehumidifier delivers an Energy Factor (EF) of 1.8 liters of water removed for each kilowatt-hour of electricity used, the Ultra-Aire 70H far exceeds this with an EF of 2.37. This means that it will remove about 29% more water for each dollar you spend.

The dehumidifier doesn’t need much maintenance. The filter should be inspected and replaced each three to six months.

The biggest headaches come with the installation. The dehumidifier has a lot of accessories to make installation easier such as ducting kits, dampers, a hanging kit but the Ultra-Aire dehumidifiers should only be installed by professionally qualified jobbers.

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one.

During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry.

I now feel convinced that I have built a guide that shows you all you need to know about air purifiers, humidifiers, and dehumidifiers. So I came up with the idea of creating this website.
