  • HUMIDITY OFFSET: Select "Humidity Offset", range is +/-8.
  • FREEZSTAT LOCKOUT OFF AND ON SETPOINT: Your control allows you to adjustable the freeze stat temperature cut-off (28°-34°F / -2°- +1°C) and turn-on (48°-52°F / 9°-11°C). The adjustability of the freeze stat allows the dehumidifier to run efficiently in low temperature conditions.
    • Set OFF with ranges from 28°F to 34°F / -2°C to +1°C; and ON with ranges from 48°F to 52°F / 9°C to 11°C.
  • DEWPOINT LOCKOUT SETPOINT: Adjustable from 36-42°F.
    In addition to the low ambient temperature 50°F (incoming air) on the previous version of firmware, the added low dew point temperature lockout will further ensure the dehumidifier runs more efficiently.
    • Simply select "Dewpoint Lockout Setpoint" to set; with range from 36°F / 2°C to 42°F / 6°C.
  • FAN IDLE: In low outdoor temperature settings, this can help make the dehumidifier run more efficiently by turning the drain cycle feature off.

WARNING: Shut off the unit and unplug the dehumidifier power cord before performing this activity.

  1. Using a Phillips-head screwdriver, locate and unscrew the screw at the top of the filter door (nearest the control panel) by a quarter turn. Remove the door and the filter.
  2. Using the T15 Torx wrench (included with the unit), locate and unscrew the four screws holding the display board in place.
  3. Once the board is loose, unplug the two wire inserts. Set aside the old display board.
  4. Insert the new display board through the open filter door, and place behind the display board opening, ensuring the arrows are pointing up.
  5. Reconnect the two wire plugs to the new board.
  6. Using the Torx wrench, screw the four screws back into the new board, holding the back of the board until all four screws are fully seated.
  7. Replace the filter and the door.

Yes. You must replace the MERV 11 pleated filter a minimum of once a year to ensure your unit is running smoothly. Depending on environmental conditions, you may need to replace it more often. Do not run your dehumidifier without a filter in place.

Because the air coming from the dehumidifier is slightly warmer than the room temperature, there can be a slight warming effect in the basement. This will further assist in lowering the Rh of the basement, as the same air at higher temperatures has a lower Rh. Click Here to learn more.

Warm air is brought into the unit and is passed over refrigerated coils, causing condensation that goes down the drain and gradually decreasing airborne moisture. Once the humidity set point is reached, the dehumidifier shuts off.

Any region with a summer dew point average above 55° needs dehumidification, separate from cooling. While one would typically think the Southern states would most often fit this circumstance, this would even include cities such as Chicago, Detroit, St. Louis, and more, as all have dehumidification needs.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) recommends keeping the relative humidity in a home between 40-60%. Outside that range your risk of being adversely affected increases. In addition, the Journal of Allergy and Clinical Immunology recommends keeping indoor relative humidity below 51% in order to deter dust mites and boost overall comfort of the home.

DH100: Up to 100 pints per day
DH75: Up to 75 pints per day
DH70: Up to 70 pints per day
DH95: Up to 95 pints per day

The DH75 & DH100 have been specially designed for small spaces such as basements, crawl spaces, closets, garages, and attics of homes, condos or apartments. Each come with adjustable feet that allow for level installations even if the floor is not level. You can even suspended them from the ceiling (with optional accessories).

Our dehumidifiers offer 5-Year Warranty.

First, let's learn a little about dust mites.

  • Genus: Dermatophagoides; Mites are Arachnids (members of the spider family).
  • Species: Dermatophagoides Farinae (DF) - commonly found in North America.
  • Size: About 250 to 300 microns (µm) in length.
  • Adult Mite Lifespan: Up to 3 months; (3 larval stages).
  • Reproduction: Female mites lay about 25 to 50 eggs.
  • Habitat: Mites live in carpet, fabric upholstery, and mattresses.
  • Diet: Human skin scale, animal dander and trace nutrients. Mites need to absorb humidity, they cannot drink water.
  • Allergen: Dust mite fecal material.
  • Body Color: Translucent.
  • Average Threshold before Developing Allergies: 100 mites/gm of dust.
  • Allergic Reactions: asthma, rhinitis.
  • Living Conditions: Temp. Range: approx. 59°F to 95° F (15°C to 35°C).
  • Relative Humidity Range: approx. 55% to 85%.
  • Number of People in the US Suffering from Allergies: 50 million and rising.

Dust mites are the most common allergen-producing organism found in homes. They live in carpets, upholstered furniture, bed pillows and mattresses. If the relative humidity in your home is below 50%, dust mites desiccate. If the relative humidity rises above 50% they strive and reproduce, their appetite increases, and therefore their fecal matter (the source of the dominant dust mite allergen) increases. Ninety percent of the population that experiences any allergy-based symptoms reacts to dust mite allergen.

Vacuum often. Washing bedding in hot water has been shown to reduce dust mites. Since stuffed toys are a breeding ground for dust mites, choose toys that can be washed and thoroughly dried, and keep them off beds to reduce the exposure received during long hours of sleep. It may also help to put stuffed toys in the freezer for a day or so.

The best solution is to control the relative humidity in your home. Dust mites can not survive in areas where the humidity level is below 50%. Have the relative humidity checked in your home during summer and fall. Relative humidity can be controlled by the use of a whole-house dehumidifier installed adjacent to the air conditioner. By controlling the humidity, you completely remedy the dust mite problem.

Our dehumidifiers are not designed to work in pool applications due to the corrosive nature of chemicals that are used in swimming pools; chemicals that can become airborne and corrode components within. You may contact Desert-Aire at (262) 946-7400, as they may have models designed for pool installation.

There could be a few reasons for this:

  1. Do you have the drain trap installed correctly? An upside down trap will cause leakage.
  2. Ensure a drain vent is installed with the drain trap.
  3. Are the PVC connections snug?
