Dehumidifiers for Home Health

Danby Dehumidifier Condensation Windows

High humidity in the summer can be uncomfortable, and musty odors in a bathroom or basement are annoying. But humidity should be kept in check for more serious reasons, too. First, there’s your health: excess moisture encourages the growth of mold and dust mites, which are known to trigger asthma attacks and cause nasal irritation, sneezing, and other respiratory discomfort. Humidity can also lead to structural problems in your home, including warped and rotten wood. It also encourages unwanted guests: rats, mice, and wood-devouring carpenter ants and termites thrive in dampness. High humidity can even boost your utility bill in summer, for the simple reason that humidity makes you feel warmer, encouraging you to crank up the air conditioner.

The higher the humidity in your house, the harder it is for water to evaporate from your skin. That’s why humidity makes you feel warm in the summer. Water vapor can also make your basement or crawl spaces musty. Since it’s a lot cooler down there, a lot more water will condense because the cool air won’t hold as much water.

The ideal humidity inside your home is around 45%. Over 50% seriously encourages growth of molds and bacteria. If any part of your home is significantly higher than 45%, you should take the steps below and, if you still have a problem, consider a dehumidifier.The higher the humidity in your house, the harder it is for water to evaporate from your skin.

Top Tips

 

At home
Many problems with excess humidity can be eliminated or greatly reduced by taking the following simple steps to stop moisture at the source.

  • Seal cracks in basement walls and foundations. Cracks obviously admit moisture. Look for them and seal them with a high-quality concrete sealer. Where there is general dampness rather than leaks, the application of a waterproof coating on the concrete may help.
  • Check plumbing. Look for leaks, but also wrap any cold-water and drainage pipes where you see condensation forming. Also look for openings where pipes come through walls and floors and seal them with a good caulk.
  • Clean and seal gutters and downspouts. Much of the moisture in basements comes from water that soaks into the ground close to the building. The first line of defense is to make sure there are no leaks or clogs in the gutters and downspouts. Once the water reaches ground level, it should be routed at least three feet away from the house.
  • Add underground drains. Serious drainage problems may require installation of underground drainpipes close to the foundation. If you already have such a drainage system, run water through it periodically to make sure it isn’t plugged. If the water backs up, you need to unclog the system.
  • Use a properly sized fan in your bathroom.
  • Use a range hood fan in your kitchen when cooking.

When shopping, look for

  • Energy Savings. The energy efficiency of a dehumidifier is measured by its energy factor, the volume of water (in liters) removed per kilowatt-hour of energy consumed. A higher energy factor means a more efficient machine. A hard-working dehumidifier can consume around $150 worth of electricity a year, so look for one with the EPA’s Energy Star label.
  • Danby DehumidifierEasy-to-read, easy-to-set controls. Many models have electronic controls–some with digital displays–that allow you to set the humidity where you want it. If yours doesn’t have such controls, you can purchase a hygrometer, which will measure your humidity. (These cost about $20.)
  • The right size. Consider the size of the area that needs to be dehumidified and how damp the area is. A moderately damp 2,000-square-foot basement, for instance, will need a dehumidifier with capacity of 22 pints a day. An extremely damp area of the same size may need one that can wring out 40 pints a day. To cope with serious humidity problems in large crawl spaces, you may want to take a look at companies that provide more heavy-duty dehumidifiers specifically designed for crawl spaces.
  • Easy maintenance. Most dehumidifiers have a water tank inside that must be periodically emptied. Some machines expect you to do it, and others do it automatically by draining into a basement drain or sump-pump cavity or pumping the water outside. If you are likely to forget to empty the water, then be sure to select one of the automatic machines. If, on the other hand, there isn’t a convenient outlet for an automatic to drain to, make sure the tank is easy to remove and carry. You’ll probably also want a washable air filter that can be easily cleaned.
  • The right model for your climate. Many dehumidifiers operate best at temperatures above 65ºF. If the temperature of the area being dehumidified will routinely fall below that temperature, you should probably buy a dehumidifier designed to handle the cold–or one that shuts off if the temperature goes too low. Below 65ºF, frost can collect on the machine’s condensing coils, interfering with its operation (just as frost does in a refrigerator). If you see frost on the coils, turn off the unit and let it defrost before starting it up again.

    I am looking at your 70 pint dehumidifier but hesitate to purchase as the fan stays on even after the desired humidity is reached. I would like a unit that the fan turns off when reduced humidity is reached, do you offer a product like this?

      Hi Blanche,

      Great feedback! Our DDR70B1CP model turns off when the desired humidity is reached and also has the 70 pint capacity you’re looking for.

      It’s currently available via costco.ca should you be interested in purchasing it.

        Hi, you say that the danby model DDR7021CP is turning off when the desired humidity is reached, but does it restart by it self when after a certain time the
        humidity starts again to go up? Im looking for this kind of unit.
        Thanks to reply by return

    What is the power/wattage consumption per hour of use of one of your Energystar dehumidifiers? TIA

      Hi Andrew,

      This will depend on the size and if the fan runs all the time.

    I recently purchased a used Danby dehumidifier in good condition but have no instruction manual. The model # is 067638 70135. Can I get a manual online?

    The DDR60RGDD must be a classified military secret. I can find very little info on it. I have a new one, but no guide. I understand it has an integrated pump but no hose or info on how to use it. Can anyone assist me? Thank you

    I haven’t been able to find a downloadable manual for the Danby Premiere Dehumidifier – Model DDR6011R. Also I may need to buy a replacement remote control for this unit.
    Where can I get both?

    My “Premiere” dehumidifier keeps freezing up. We clean the filter but the problem persists. I looked on the website for warranty servicers and one seems to be out of business(the phone number has been disconnected) and the others aren’t taking Danby products any more. What do you recommend?

    I buying a dehumidifier for a very large fininshed basement. I am dowen to choosing between two different units that you have. I especially want quiet with adjustable and auto humidity control. I’m having a difficult time deciphering the diffenence between the ADR70A2G AND THE DDR70A2GP. They seem to have the exact same options and I can’t tell which runs more quitely?
    Thanks,
    Steve
