In this buying guide, we are going to be looking at three dehumidifiers. The BLACK+DECKER BDT30WTA, the BDT50WT, and the BDT70WT. All three of these dehumidifiers are great. Each one has its own distinct features, attributes, strengths, and flaws.

Dehumidifiers are great because they remove all of the excess moisture in your air. From doing this, they prevent the growth of mold and mildew, and they make your air much more pleasant to breathe.

One of the benefits of the BLACK+DECKER BDT30WTA is how efficiently it goes about fulfilling that purpose.


The BDT30WTA can remove up to 30 pints of water from your air, within the span of a single day.

That’s a lot of moisture, and it stores all of this in a large moisture tank. But, don’t worry about you running it for too long and having the tank overflow, because there is a sensor in place. This sensor tells the dehumidifier when the tank is full, and then it shuts off.

Since this is an Energy Star certified dehumidifier, it doesn’t use that much electricity, either. So, you can run it for those 24 hours, and your electricity costs won’t skyrocket.

Due to the sheer amount of water this dehumidifier can remove from your air, it is recommended for space such as basements and living rooms.

To use the dehumidifier, just turn it on and choose a fan speed. On a small screen, you will see the temperature and humidity level that each particular fan speed corresponds to, and from that information, you can choose the ideal speed.

One downside is that the moisture tank is only 8.5 pints, which means you do have to empty it on a fairly regular basis. However, you can also install a direct drainage system, so that you don’t have to empty a moisture tank. But, that costs some extra money, since BLACK+DECKER doesn’t give you the tools needed for that.



So, unlike the BDT30WTA, the BDT50WT can extract up to 50 pints of moisture, within a single 24-hour period. That’s quite a bit more moisture, and because of this fact, the BDT50WT is a great dehumidifier, if you have a large space/floor that you want to dehumidify completely.

To better accommodate this larger volume of moisture, instead of having just an 8.5-pint moisture tank, you now have a 16.9-pint bucket.

Other than that, though, the features are very similar. You have the same choices when it comes to fan speed and the same humidistat. This humidistat tells you what the temperature and humidity levels in your room/space are, and then it allows you to adjust the speed of the dehumidifier to accommodate those levels best.

Ultimately, the BLACK+DECKER BDT50WT is a great dehumidifier, if you have a larger space to dehumidify. If you don’t, though, then the BDT30WTA is still a great choice.



Finally, we come to the BLACK+DECKER BDT70WT. As you may have gathered, from the title, this particular dehumidifier can extract up to 70 pints of moisture within a single 24-hour period. This is the fastest and most efficient dehumidifier on this list.

With that being said, the features, in comparison to the other dehumidifiers on this list, are pretty much the same. You have the same fan speeds and settings. The same humidistat. The same 24-hour timer. Even the bucket can store the same amount of weight, at 16.9 pints.

Because of this, the only real reason you should purchase the BDT70WT is if you have a large space that you need to dehumidify and if you want to dehumidify that space in a very brief period.

Other than that, though, there isn’t much reason to purchase this one, over the others.

With that being said, though, this is still a very high-quality dehumidifier.

BLACK+DECKER Dehumidifier


Every one of these dehumidifiers is very well-made. If you want to dehumidify a smaller space or even a large space, then the BDT30WTA is a great choice.

If you want to dehumidify a larger space, and you want that dehumidification process to be swift, then you can’t go wrong with the BDT50WT.

Finally, if you want to dehumidify a really large space, and you want the process to be quick and easy, you can’t go wrong with the BLACK+DECKER BDT70WT Dehumidifier.
