Quick Review Summary

The Toshiba TDDP5012ES2 is an average dehumidifier. It has most of the features and much of the functionality you might want in a dehumidifier, but it doesn’t do anything especially well.

This unit was also only an average to below average performer in our hands-on performance testing. Its performance in those tests as well as all of its features and functionality are covered in detail below.

Performance Test Results

Energy Efficiency

The Toshiba’s measured power draw was 578 watts. The 50 pint units we tested had a measured power draw in the 560 to 610 watt range with most units drawing approx. 570 watts. Thus, the Toshiba’s power draw was ever so slightly higher than average.

The real concern here is its performance in our moisture removal tests. The Toshiba took much longer than most other 50 pint units we tested to dehumidify our test space from 90% down to 40% relative humidity (more on this test in just a moment).

Energy efficiency is dependent on two factors – power draw and how long an appliance draws that power for – i.e. how long it takes an appliance to do a particular job.

The TDDP5012ES2 not only had a slightly higher than average power draw but it also took much longer to dehumidify in a real world environment in our testing. This gives this unit below average energy efficiency compared to all of the other 50 pint dehumidifiers we tested.

Noise Output


We placed a sound meter right above the control panel and 10 ft. away from the dehumidifier to measure its raw noise output.

The Toshiba is a side exhaust unit and so it had an advantage in our testing. Why? Because its side exhaust directed much of the noise away from the dehumidifier – and away from the sound meter. Top exhaust units emitted noise directly at the sound meter when it was placed above the unit’s control panel. 10 ft. away from the dehumidifier this advantage was less pronounced.

In any case, our testing showed side exhaust units to have a lower raw noise output than top exhaust units. The same applies to the Toshiba. Because it is a side exhaust unit it was tested to be “quieter” than most other 50 pint dehumidifiers we tested.

On high fan speed above the unit’s control panel it was measured 61.2 dB of noise output. 10 ft. away it was measured at 52.4 dB. The “quietest” 50 pint dehumidifier we tested, the hOmeLabs HME020031N, was measured at 59.3 dB and 50.3 dB in the same respective tests. Top exhaust units were measured at 70+ dB and approx. 54 dB in the same respective tests.

Note, however, that raw noise output is only part of the equation when it comes to evaluating dehumidifier noise output. Another important consideration is the quality of the noise.

Here, the Toshiba, like all the other side exhaust units we tested, didn’t do as well.

You may have wondered why we didn’t mention low fan speed numbers earlier. The reason is this: you’ll almost never want to run a dehumidifier on low fan speed.

Why? Because on low fan speed it won’t remove moisture as fast AND the white noise the fan produces won’t hide compressor noise nearly as well.

The Toshiba’s compressor makes quite a bit of noise (just like the compressor in most other 50 pint units we tested). And because its side exhaust sends all fan noise in a particular direction, it doesn’t mask compressor noise very well (unless you point the side exhaust directly at you of course).

Top exhaust units better distribute fan noise throughout a whole room (the noise is directed upwards omnidirectionally throughout the whole room). For this reason top exhaust units are “loud” but most of that loudness comes from fan noise. And it’s actually a good thing that you’re hearing more fan noise (due to the upward facing exhaust) with these units, because otherwise you’d be hearing more compressor noise, and that’s a much less pleasing noise to listen to.

Moisture Removal

We measured how long it took each 50 pint dehumidifier we tested to lower room humidity from 90% down to 40% and then from 80% down to 50% (an easier test).

We saw much more variance in the first test (90 to 40%) than the second test (80 to 50%) as it was by far the more difficult test. Most 50 pint dehumidifiers can handle 80% humidity just about equally well and can lower room humidity down to 50% relatively easily. The true test is the 90 to 40% test as 90% RH represents extreme moisture levels and 40% RH represents very dry air.

It took the Toshiba 12 minutes, 42 seconds to lower room humidity from 90% down to 40% in our 50 sq. ft. test space. For comparison, most other 50 pint units took only 10 to 11 minutes. The top rated Frigidaire took only 7 minutes, 56 seconds.

It took the TDDP5012ES2 6 minutes, 44 seconds to lower room humidity from 80% down to 50%. Most other 50 pint units had a time in the 5 and a half to 6 minute range. The top rated Frigidaire was again a bit of an outlier with a time of 5 minutes, 19 seconds.

These results speak for themselves. The Toshiba was an especially poor performer in both moisture removal tests.

Hygrometer Accuracy

The TDDP5012ES2 also doesn’t have a very accurate hygrometer. It often displayed readings up to 4% above the actual room humidity. Top rated units were accurate to within 2% of actual room humidity.

Included Features, Functionality, Build Quality, Warranties, and Value

Durability (Build Quality)

General Impressions

This unit features average build quality. It doesn’t feature any parts or materials that make us especially concerned about its long term durability, but it also doesn’t feature any parts or materials that make us especially confident about its long term durability.

Consumer Feedback

This unit is essentially brand new to market at the time of the writing of this editorial review. We usually survey consumer reviews written after a few years of ownership to see if there are any issues with the unit we may have missed during testing. We can’t do that as of yet with the Toshiba since it’s only been on the market for a few months.

Overall Category Score

The unit earns an average 3.5 for durability.



This unit features a timer that can be set in 1 hour increments up to 24 hours. Most other 50 pint units allow you to set the timer in half hour increments up to 12 hours, and then 1 hour increments from 13 to 24 hours.

The Toshiba features two fan speeds. Again, you’ll almost always want to use only one – high fan speed. There are models on the market with three fan speeds.

This unit does feature a continuous mode. On this setting the unit will run continuously until you manually shut it off. Most other 50 pint units we tested also come equipped with this mode.

The TDDP5012ES2 does come with an auto mode called “comfort” mode. We’ll say more about this in the next section on versatility.

Overall Category Score

The unit again scores an average 3.5/5 in the category.


Set Humidity Range

The Toshiba allows you to set a desired humidity level between 35% and 85% humidity. You can adjust the setting in 5% increments.

On this “manual” mode the unit will cycle off automatically when the built-in hygrometer reads that room humidity matches the set humidity.

The unit’s “comfort” mode sets a desired humidity level automatically. And then the unit works much the same as it does on “manual” mode. Note that you’ll probably never want to use “comfort” mode as you’ll be able to establish the exact humidity level that’s comfortable for you by simply adjusting the desired humidity level on “manual” mode over the course of a few days. For example, you might set the unit to 55% RH on the first day, find that it’s not dry enough, then set it to 50% RH the next day, and from that day forward just leave it on 50% RH for many months as 50% RH may be comfortable for you. In contrast, “comfort” mode might set the unit to 55% RH, you may not be comfortable at this RH, and then you’ll set a lower desired RH manually anyway.

Operating Temperature Range

The Toshiba’s minimum operating temperature is 41° F. The user manual doesn’t state a maximum but we think it’s safe to assume it’s in the 89° to 90° F much like every other compressor based dehumidifier on the market.

Gravity Drainage


The unit has a drain outlet that doesn’t require an adapter for use. Certain models, like the LG UD501KOG5 and Keystone KSTAD504D, require that you install an adapter before connecting a garden hose to the outlet.

Built-in Pump

The TDDP5012ES2 doesn’t feature a built-in pump. You can, however, still pump collected moisture by draining through the gravity drain outlet into a condensate pump (purchased separately).

Overall Category Score

The Toshiba earns a 4.5/5 in the category.

Extra Features

Temperature Reading

This unit does not display current room temperature.


This unit features a defrost mode with an accompanying defrost indicator light (on the main control panel). Defrost mode is activated if frost builds up on the unit’s evaporator coils (the evaporator is found behind the unit’s back grille – see the photo below). On defrost mode the compressor shuts off and the fan continues to run to melt the frost. The defrost indicator light alerts you when defrost mode is activated.


Check Filter

This unit does feature a check filter light on its control panel.

Overall Category Score

The Toshiba earns a 4.5/5 in the category.

Ease of Use

LED Display Clarity

The display is low quality but easy enough to read.

Setup Difficulty

The unit is easy to setup and use.

Filter Removal Difficulty

The unit’s filter is easy to access and remove. It pulls out of the top of the back of the dehumidifier.


Manual Clarity

The TDDP5012ES2 manual is easy to follow and understand.

Water Tank Size


The unit’s water tank has a capacity of 14 pints – right around the average for the 50 pints/day size class. Some high capacity units have a smaller tank (e.g. the Keystone KSTAD504D has a 12 pint tank) while others have a much larger tank (e.g. the Frigidaire FFAD5033W1 has a 16.9 pint tank). The larger the tank, the more infrequently you have to empty and replace it (unless you’re using gravity drainage, of course).

Overall Category Score

The Toshiba earns average marks in the category – a 3.5/5.


The TDDP5012ES2 weighs just under 44 lb. The average for the 50 pint size class is around 43 lb.

The unit features side pocket handles and a plastic “buckle” on the back around which you can wrap the unit’s power cord.


Overall Category Score

The Toshiba earns a slightly above average 4/5 for portability has it has just about an average weight for a 50 pint dehumidifier and it features excellent cord storage.

Warranty (Manufacturer’s)

The TDDP5012ES2 comes with an industry standard 1 year warranty.

Only a handful of 50 pint dehumidifiers come with a longer warranty. The top rated Frigidaire FFAD5033W1 isn’t one of them. Like the Toshiba it only comes with a 1 year warranty.

The hOmeLabs HME020031N does come with a longer warranty – 2 years plus an additional 6 months if you register your purchase with the manufacturer.


The Toshiba TDDP5012ES2 tends to be priced towards the lower end of the range for 50 pint units. But it’s a very average, if not below average dehumidifier overall. And since value is just as much about what you get as it is about what you pay, this unit earns only an average 3.5/5 for value.


  1. Allan Robinson says

    Purchased in May 2020, cost $230 plus tax. Early Sept 2021, coils all iced up and almost no water in bucket. Contact Toshiba Customer Service and their answer is sorry, out of warranty. This unit only 16 months old. Don’t buy this product, it is J.U.N.K.

  2. Christine says

    The compressor isn’t working. It blows warm air. The unit is only 6 months old. What is wrong?
    Where can I find instructions online? I can’t find mine.

  3. Jim says

    Avoid this product! It has a 1 year warranty and mine failed after 1 year and 3 weeks! Toshiba refused to repair it because it has a “1 year warranty “. Planned obsolescence at its finest! This is the last Toshiba product I will buy.

  4. Thom says

    Well, I’ve seen many others experiencing the same problem I’m currently having… the unit won’t allow me to move the desired humidity level, won’t dehumidify, yet the compressor runs even it it’s turned off. What I don’t get is not being able to get any answers or solutions to this problem, nor Toshiba standing behind their engineering and given the mass situation do either a recall and replace or free replacement demonstrating their commitment to quality and their customers. That is exactly why I’ll never buy GE again after having a $2k refrigerator need a new damper after 13 months, which was likewise a common problem on that model. How these companies get away with this I’ll never know.

  5. Alwyn Allan says

    Mine failed in a year. It was past warranty when I noticed. The refrigerant leaks then they ice up, even in warm temperatures and with clean filter and coils. Toshiba (or whoever uses that brand) just wastes your time until you give up. I made a video

  6. Phil says

    Worst dehumidifier that i have ever purchased. Worked 4 months tops. Put it away and when we got it out to use it was passed warranty by 2 weeks. DO NOT BUY!!!!

  7. Kerry says

    After 1 year and 1 month (out of warranty, purchased 7/21/20, first noticed ice on coils 8/11/21)), I noticed ice on the coils. I had checked the unit since I purchased it and noticed the DEFROST feature had been working. To my surprise, DEFROST quit working.
    Called the Contact number provided in paperwork. They asked me to perform a few checks on the unit such as is the grill clean, is there adequate ventilation, etc. All of that checked out. Average basement temp was 70. They said that was all they could do since the product was out of warranty. The did suggest I call a local repair man, if i knew one. Suggested the DEFROST sensor was probably malfunctioning.
    Wrote a review on Home Depot site about the unit and stated I would not purchase another Toshiba product. Received a response from Toshiba to check the room temp and maybe increase it (I originally stated temp was between 55 and 60, my mistake). Unit is still icing up. Am currently running it during the daytime for a period of time and shutting it off at night until I can find a QUALITY product.
    Do not invest your money in this product! It is not worth it!

  8. Paul DeSmidt says

    I purchased the Toshiba Dehumidifier model TDDP5012ES2. I am using the tank only and it runs great and fills quickly. Problem is, it overflows the bucket. I can see where the swivel point at the top of the bucket should hit the switch on the back inside upper left. But that doesn’t seem to stop the water from draining into the tank and overflowing. What am I doing wrong?

  9. Mot says

    The hygrometer is accurate but only when the unit is running. As soon as the fan stops, it shows ~10% RH higher than actual. This causes the unit to cycle on/off every few minutes unnecessarily: it turns off when it gets to the desired RH, then it incorrectly thinks that the RH increased by 10% (because it’s off), then it turns on, then the RH quickly returns to being accurate, so it turns off again, ad infinitum. I’m surprised your testing didn’t reveal this flaw, because, looking at online reviews, it seems to be intrinsic to the design of the device.

    Also, the one I had broke after less than a year of very light use, which also seems to be a frequent occurrence based on other customer reviews. The control panel and fan worked fine but it sounded like the compressor would never turn on.

    The unit seems to be a white-label Chinese device that’s branded by Toshiba. If you search Amazon for dehumidifiers, there are a lot for sale under different brand names that look very similar to this one and have almost exactly the same control panel. I assume they’re all basically junk.

      I agree, mine died just after 13 months and Toshiba would offer no assistance with repair or replacement. I would recommend to not purchase Toshiba!

    • Admin says

      Comfort mode is an automatic mode that sets a “comfortable” humidity level for you. On manual mode you decide and select the exact desired humidity level.

  10. Sam says

    Does the TDDP5012ES2 actually have a filter or just a screen. If it has an actual filter where can I get one? What size is it?

    • Anonymous says

      I had the same problem, this seems strange but I put my finger in the drain hole looking for something to divert the water, did not feel anything but it is now draining out that port.

  11. André Bouchard says

    We can’t use the continuons draining We use à Water hose but the Water-fill in the Bucket. Do We have something el se to do or if it’s defected

    • Damian says

      I figure it out and wanted to share with everyone, so I’m copy/pasting!!! You need to have the unit higher compared to the hose, it works with gravity, is pretty crazy but raise it and you’ll see that it starts again, even with a full bucket..

  12. Paul says

    Machine reads 30 RH since new. Won’t collect water. I changed setting to 50 RH, waiting to see what happens. Set on continues for 8 hours

  13. Peter says

    I have it set on continuous with a hose drain to my sump well but the unit is still filling up the reservoir. Is there something else I need to do to get it to drain out the hose?

  14. VJ says

    Had the unit running all
    Night and woke up to water on my floor. Tank full light was on but unit never shut off, the hose drain plug was tight.

  15. hugh donald says

    I purchased my unit a few months back, I had no problems, a few weeks back I shut the unit off for a few days while we were away, upon return I started it and it continues to build up frost to the point that it melts on the floor and there is no water in the water holding tank. I have melted the ice a few times but it continues to frost up to the point of half way up the coils. Please help.

  16. Manny Quintero says

    I attached a water hose to the drain outlet in the rear of the unit, in order not to have to use the tank in front. the unit continues to drain in the front tank. I can not get it to drain out of the drain outlet.
    I need help to resolve this.

    Thank you.

    • Kurt Schnittger says

      I have my dehumidifier set on continuous. The hose is connected properly, and is running down hill into a drain. yet the front tank on the dehumidifier keeps filling up, and the unit keeps shutting off due to it being full. I see that multiple people on this site have issues with this. Any suggestions?

  17. Raymond Webber says

    Will this unit restart after a power failure in the area?
    If not do you have a unit that will accommodate this need?

  18. leonard h littmann says

    if i run the unit on continuous with a hose attached that is above where the water is draining to is this ok? And I imagine the place where the water is draining to must be lower than where the hose is hooked into the unit, right? also, what humidity level will be reached by setting it on continuous mode. Thanks

  19. Tom says

    i have a hose connected to drain outlet in back but does not empty water. Device still shuts off until drawer is emptied.

  20. Paul Firetto says

    We just bought this unit and don’t understand how to set the timer so it will shut off at the programmed time and go back on at the desired time. The explanation in the manual is not clear. What are we doing wrong? Also, we are using it in the basement. Can we put it in a separate room with ventilation where we can pump the water into a drain?

    • Admin says

      The timer can only be set to turn the dehumidifier off at a particular time within 24 hours. It can’t be set to turn the unit off and then back on again.

      Yes, you can put the unit in a separate room as long as there’s adequate airflow between that room and the rest of the space you want to dehumidify.

  21. Sam says

    I have the 70 pint and it was working then it suddenly won’t start, showing “88” on screen with all lights on. Then I pulled out the bucket and it shows P2 and I put it back (empty) but still says P2 and won’t start. What is the problem??

  22. Michele says

    I purchased the dehumidifier because it has a self drain option. It’s not working and the manual is not helpful


    RE: The TDDP5012ES2 Toshiba dehumidifier.

    In the manual mode the unit turns itself off when it reaches the set humidity , will it turn itself back on when the humidity goes up say 5 or 6%?

  24. Michael Schaefgen says

    How do you change the humidity on this unit. The manual states it can’t be changed on continuous or comfort. Mine doesn’t have a manual button to push, so how do i change it?

    Thank You, mike

    • Admin says

      As long as continuous or comfort mode isn’t activated, you can set a desired humidity level using the arrow buttons on the control panel.

      • Anonymous says

        Thank you for this response. The manual isn’t clear on how to engage “manual” mode and it’s not really intuitive looking at the control panel. I was expecting a manual button. Your response cleared it up!

  25. kaizen099 says

    Hi, I just bought this unit yesterday at the Home Depot for $229. I had to set the unit to 55% humidity so it would not continue to shut on and off. When I set it lower it would shut down automatically for about 30 seconds then it would start again. Once I set it 55% it did not turn on again. Both of my calibrated humidistats are currently reading 51% and 50%. The humidistat on this unit is a bit flaky it is currently reading between 54-55%, also did your units compressor turn on and off a bit aggressively? I’m not sure if I am going to keep the unit yet. Home Depot has a six month return policy on this unit…thanks.

  26. Marilyn Burton says

    will the unit shut down when it reaches to setting desired for the humidity? Or do you have to set the timer to only run for a certain amount of time?
