With this 70-pint Frigidaire dehumidifier, it's possible to keep the humidity in my basement consistently around 50% to 60% (or even lower, depending on basement size), which will prevent mold, mildew, rust on tools, damage to electronics, and other nasty things that excessive humidity can, and will, do.

This model has all the desirable features:

  • Built in humidistat to maintain humidity at users pre-set level
  • Auto shut-off when collection bucket is full (if using collection bucket) with visual full indicator
  • Capability to bypass collection bucket by using hose to drain directly
  • Washable, re-usable anti-microbial filter
  • Caster wheels to make for ease of movement, if need be
  • Top and side handles
  • Dual fan speeds

This Frigidaire unit is fairly quiet when the fan is running at the lower of the two speeds. Of course, you will hear it running while you are in the basement, which I find pleasing because I know it's working. I find it's like a nice low-level white noise while working in my basement workshop.

A handy feature I like about this model is that you can bypass the 2 gallon collection bucket and attach a hose directly to the drain spout, if you have a floor drain close by. Hence, the biggest chore with a dehumidifier, that of emptying the bucket (depending on how low you want the humidity, this could be a daily chore), is not necessary. Indeed, it should be noted that the design lends to the bucket being slightly difficult to remove and empty until one gets used to it, so if you can position the unit near a floor drain and use a hose, it is recommended to do so.

According to the Frigidaire product lineup, this 70 pint dehumidifier is designed for medium sized rooms. However, it works very well for my basement, which is about 30' x 50'. It's important not to "cheap out" when buying a dehumidifier. A model that is not powerful enough for your needs will simply be a waste of money; continually running but yet, not able to do the job.

This model has a filter clean reminder light that goes on after 250 hours of operation. This is a handy reminder that it's time to clean the washable filter. As well, it has a "bucket full" indicator light, and the dehumidifier will stop running until the bucket is emptied.

This model is 11.3 x 16.1 x 24.6 inches and weighs 49 pounds.

Here are just a few excerpts from the many glowing reviews by owners on Amazon.com:

Most noticeable are differences from the previous model which indicates some very significant improvements:
FIRST, it is amazingly quiet! In fact it was so quiet that I wondered whether the compressor was even working. I disconnected the drain hose (I use a gravity drain) to see whether the bucket would fill up. It did so in just a few hours! I would support the claim for 70 pts in 24 hours. The old model was quite noisy and, although in a different part of the basement, interfered with listening to the TV in the basement rec room. Not the case for this model.
SECOND: The exhaust for this model is out the TOP! Not out the back as in most older models, or the side as in the previous version of this one. How novel ... very unlikely to have an obstruction out the top and that also significantly aids in the air circulation. I wonder why no one ever though of this before. The squirrel cage fan now exhausts directly up and that may have something to do with it's quiet operation.
THIRD: The hose attachment for the gravity drain is now outside of the case and very easy to get to. It was very difficult to attach the hose in the previous version.
FOURTH: It was less expensive than the older model, which is also still available on amazon.com.


I am extremely pleased with my Frigidaire FAD704DUD Dehumidifier. It replace an LG unit which did not work well at all right from the start. The LG unit was noisy and the coils would freeze up from time to time even though it was the low temperature model. Our basement seldom drops below 60 degrees so the unit should not have frozen up. The Frigidaire was superior in every respect. Its is very quiet compared to the LG unit. I have it draining to a small automatic pump. I don't have any basement water issues but like most basements, the humidity does go up during the summer months. I just leave the humidity control set at 50% and the unit does the rest flawlessly.


Purchased this dehumidifier from Amazon several weeks ago to cure a humidity problem in my basement. I had installed a bamboo floating floor in February, and while the planks were given sufficient time to acclimate to the basement, humidity was low during that period. As such, when summer arrived and relative humidity levels rose, certain sections of my floor began to buckle. This was even after having left .5" of gap between walls for expansion!

Suffice it to say, I was a little hesitant purchasing this dehumidifier due to the sole negative review left. I'm glad I took my chances as this dehumidifier has been running non-stop now for over a month. I left it on continuous cycle for about 4 days which brought the RH level of 75% in my basement down to 50%. Once humidity dropped to an acceptable level, I set the unit to run only when humidity hits 50% or higher.

My floor has now returned to normal and the air smells cleaner and less musty as well. All in all, very satisfied with the unit. Hopefully my opinion remains the same in the long run, but for now, I believe that this is a well manufactured unit.

For your reference, my basement is finished and quite large at approximately 1700 sq ft. This single dehumidifier has kept RH steady in the basement with all doors in each room open.
