Does the dehumidifier require any maintenance?

Yes.
 
  • For the DH70 & DH95:  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.
  • If deemed necessary: Flush the unit with water to ensure the drain is clear.
 

What does the dehumidifier weigh?

Model DH70:  65 lbs.
Model DH95:  73 lbs.
 
 
 

What are the electrical needs of the 1300 dehumidifier?

It requires a 115V 60Hz, single phase, 15 amp dedicated circuit.
 
 

Other than dehumidification, what is the benefit of running the dehumidifier in a basement?

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.
 

How does the dehumidifier know it needs to remove moisture?

When humidity reaches the set point on the humidistat, the unit turns on to remove humidity. The compressor is turned on if dehumidification is needed. The dehumidifier will run until it once again reaches desired humidity levels.
 
 

What areas of the country need whole-house dehumidification?

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.
 

Why do you want to keep indoor relative humidity (Rh) between 40-60%?

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.
 

How much moisture do each of your dehumidifiers remove in a given day?

DH95:  up to 95 pints per day
DH70:  up to 70 pints per day
 

What are my installation options?

The DH70 & DH95 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).
 
 

What is the size of the DH Models?

The DH 70:  13” H x 13” W x 27 1/4” L
The DH95:  14 1/2” H x 14 1/2” W x 29 1/4” L
 

What warranty do you offer on your dehumidifiers?

  • DH Models:  5-Year Warranty on the compressor and a two-year warranty on all parts.

How can a dehumidifier reduce the dust mite population in my home?

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.
 
 

Can I install your dehumidifier in my pool area?

Our HealthyAire® 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.
