    Great video!!! Pleasant, informative and so well done!! More of these please! I learned several things that I was not aware of before watching the video!

    Having an older home with a crawl space for a basement, a good dehumidifier is critical. Thanks for the education about how to monitor the levels – I learned something new!

    Interesting tip about using a smart plug to check on the energy use of the dehumidifier. I suspect that our dehumidifier costs quite a bit more than 30 dollars a month to run, and we’re only bringing down the humidity to around 60-65%. It’s tricky to balance out humidity versus cost.

    How timely! We just bought a dehumidifier this last weekend because of the basement “stink”.

    Thanks for reminding me it’s time to do something about our dehumidifier which isn’t performing well.

  10. Bob said:

    I agree with Megan. Despite following the recommended usage guidelines here, I feel that the dehumidifier is really an energy hog. Even if it’s running just a few hours a day, our energy bills go up in the Summer (as compared with early Spring or late fall and this is with little to no use of AC.

    Nice to know there’s a way to monitor usage though.

    I lived in Arizona for a couple of years and would try my best to avoid the humidity cliches, but it’s so true. One of the things I’ve noticed in moving to a townhouse is the extreme differences in temperature and comfort depending on the level. I’m wondering if adding a dehumidifier to the mix might help. Any suggestions from others would be appreciated.

  12. danny andersen said:

    Good video. We have an energy star device, but have had it set at 60%, so I will adjust to 50%. I also have the option to use a 3 hour cycle, a 6 hour cycle, or neither (ie, it runs as necessary). What do you suggest is best?
    Thanks.

    at 2:35 pm on July 6, 2017
  13. danny andersen said:

    Another question. Our energy star device is more than 10 years old. Are newer versions better? Is there a particular brand that is best?
    Thanks.

    Very informative – especially for those of us who do not have central air. The fact about the setting of 50% was especially helpful. I did not know what the correct setting should be.

    What is the energy difference between an older model and a new energy star dehumidifier. I know it was huge when I replace a refrigerator freezer.
    Same thing here?
    Thanks

  22. Stuart Utley said:

    Not familiar with the smart plug. Is it like a watt meter that can also power the device plugged into it on & off? If so, can it do so at preset times and/or based on energy usage etc.?

  27. Rena Crispin said:

    I am so glad I listened to this! I’ve been keeping mine at 30% because I had no idea where to set it. Now I know that 50% humidity is good and that anything less than 50% is a waste of money. Wow, I’m changing it right now.

    at 4:41 pm on July 6, 2017
  28. Tia Davis said:

    This is a great educational clip! I didn’t know 50% is the recommended level for the dehumidifier so I appreciate the advice. It’ll cost to run it but we need to consider the need to replace windows and musty carpets sooner than later because of not running one enough or at all.

    Thanks!

  33. Elizabeth Armstrong said:

    This is a very nice video with good information. The pace is just right and the man speaking has an upbeat tone of voice which encourages listening to his points. Thank you MG&E. I’d eagerly read other presentations about energy usage and home comfort levels all year ’round if you produced more such videos.

    Like others who commented, I’m glad to know about the smart plug! A great idea to understand energy usage.

    I have found that this year (2017) the humidity levels have contributed to my sinus headaches. I’ve never had this kind of reaction before. It may be my age, 73, but I suspect it has been the prolonged humidity. My small home has no basement, so don’t experience the dank smell, but I do think the AC is making a difference not only in the cooler air but the lower humidity in my home.

    Does it help to run a dehumidifier along with an air conditioner even if you don’t have any trouble with basement humidity or musty smell?

    Mold loves moisture and heat. Another great reason to spend a little more now to preserve home and health in the future.

  36. Edwin Gilbert said:

    Bought a big Sahara unit 12 years ago. Humidity set to 65% . Last bill used 200 kwh more than April. Finished basement – live there in the heat. My allergies act up when in AC all day. So have not turned ours on in 16 years.

  38. Bobbi Zehner said:

    Thank you. We do use a dehumidifier in our basement for the very reasons you stated. But clearly, we need to upgrade to a more efficient model.

    at 8:49 pm on July 6, 2017
  39. Jennifer Mitchell said:

    We have been using a dehumidifier for years to do what your video suggests: keep the smell and mold absent from our basement. What I did not know is that 50% is the target number, I often kept it lower. We recently purchased a new model that has a remote setting. We’ll set it at 50% now.

  42. David said:

    Very cool. I never new that less than 50% humidity is basically a waste of energy. I’m going to check my setting when I get home tonight!

  54. Mary Christian said:

    I had a smelly basement years ago, but got out all the mildewed paper boxes, paper anything, and moved all into plastic bins…treated mildewy wood stuff I wanted to keep with tea tree oil. I painted and decorated half the space then…it is a very fun T.V./lounging space and so cool in the summer. Then I set up a high quality dehumidifier (I actually run two sometimes for a space around a corner) – one drains right into the floor so I don’t have to remember to emtpy the bucket all the time. I don’t like the extra I have to pay in the summer, but figure it offsets the winter heating bill I don’t have, and also, it is a trade-off for having a space that is nice, and never smells of mildew. I used consumer reports to buy mine a number of years back.

    The video made me realize that we probably need a new dehumidifier in our basement. I know the one we have now is quite old. Thanks for the informative video.

  58. Paul Milenkovic said:

    The efficiency of refrigeration dehumidification equipment depends on both humidity level and temperature. Each 5 degrees colder in temperature requires a humidity setting 10 percentage points higher to be at about the same level of energy consumption.

    Furthermore, humidity gauges and dehumidifier digital readouts are not always that accurate.

    When I brought up with my allergist about 50% humidity being a difficult level to achieve, I was told, “The important thing is that you have a humidity gauge and have some awareness of its reading.” Use your nose and other senses as a guide.
