In humid environments, dehumidifiers help air conditioners make an indoor living space comfortable. Dehumidifiers also prevent mold and clamminess in basements with flooding and groundwater.
TOSOT is one of many dehumidifier brands, but its dehumidifiers are especially powerful for the price. This review helps you get to know TOSOT dehumidifiers and assess whether a TOSOT model is right for you.
TOSOT Dehumidifiers Compared
Why Choose a TOSOT Dehumidifier?
Safe To Use
All TOSOT dehumidifiers are UL-listed. TOSOTs are safe for continuous unattended use—all have automatic shutoff, in case the tank is full or disrupted, and power outage restart, maintaining the user’s settings.
Quiet for Home Use
TOSOT is competitive with other dehumidifier brands when it comes to loudness: The loudest model is no more than 52 dB(A) on high fan speed; users compare this to the sound of a window air conditioner.
Dual Drainage Options
There is an optional internal pump on the largest model—the 50-pint. This is ideal only if you really need to pump water upwards. Otherwise, using the gravity-fed drainage is suitable for continuous unattended use. All models have a removable drain bucket that needs to be emptied, at most, every 5 hours.
All TOSOTs have washable air filters. The unit flashes a reminder every 250 hours of use. Remove the drainage tank, slide the filter down and out, and vacuum dust out. If deeper cleaning of the filter seems necessary, use warm water and mild detergent, but be sure the filter is dry before sliding back in.
Highly Rated, Popular Models
TOSOT dehumidifiers get high ratings on Amazon, and most users say they are impressively effective. As you browse, you might notice that these have both 2012 and 2019 pint-per-day ratings. This is because the Department of Energy (DOE) changed its rating criteria in 2019 from the 2012 standards: testing temperature reduced from 80⁰F to 65⁰F; and cooler air generally does not hold as much moisture, so the pints per day for the exact same model appear to be lowered.
The 1-year warranty with optional 6-month extension is comparable to some other similarly priced dehumidifier brands and models. Still, many have slightly longer warranties—this is a weak point of this brand.
- Adjustable Humidistat:
Users generally find TOSOT’s humidistats accurate. This is important because otherwise the unit is running out of control, not responding correctly to the user’s settings or current relative humidity in the room.
- Automatic Defrost Control:
Automatic defrost is always convenient and is a key feature in safe, unattended dehumidifier use. (When Defrost Mode is on, the unit will put out cool air, as fan is on but compressor is off; and it might turn on and off more often.)
- Automatic Shutoff:
This is an important safety feature to save the surrounding area from water damage from an overflowing tank. Also, the machine will shut off if malfunctioning, which in theory could prevent other types of disasters, too.
- Bucket Full Indicator:
TOSOT dehumidifiers have both an indicator light and beep alarm when the bucket is full. This could be annoying, but it does let you know you need to do something if you want to keep up dehumidification. Also, it keeps you from allowing old water sit and grow mold in the tank.
The 50-pint models are heavy enough that casters are a necessity for convenient transport. These are not whole-house duct dehumidifiers; therefore, it is good to be able to move them. The 360⁰ casters, while too small to help on many carpets/rugs, are sufficient for most users.
- Continuous Run:
For serious moisture build-up or rooms you do not visit often, it is good to have a safe, energy-efficient, constant-running dehumidifier with reliable water drainage.
- LCD Display:
TOSOT actually has an LED display—a modern improvement of LCD. The clear screen allows better feedback between user and dehumidifier—you can see exactly what humidity you have set and what humidity the machine is currently sensing.
The TOSOT Appliance Range Explained
TOSOT makes an assortment of affordable residential products: window and portable air conditioners, true HEPA air purifiers, dehumidifiers, and an ultrasonic humidifier. Most of these are Energy-Star-rated and UL- and ETL-listed. Their devices are competitive in noise level and ease of use. TOSOT’s 1-year warranty (with 6-month extension, if you register a new unit) is competitive with similar brands.
All TOSOT dehumidifiers are compressor dehumidifiers—a refrigerant-filled compressor-evaporator system cools humid air until vapor condenses out. All TOSOT dehumidifiers are the same build, just in different sizes. (The only exception: you can get the largest model with built-in pump.) Larger units are more powerful and have greater capacity, meaning they will pull more pints of moisture out of the air faster.
4 TOSOT Dehumidifiers Reviewed
1. TOSOT GDN50BA-A3EBA2E
Best TOSOT Dehumidifier with Pump
|Moisture Removal||50 pints per day|
|Coverage||4500 sq. ft.|
|Dimensions (W x D x H)||14.8 x 11.4 x 24.1 inches|
|Noise Level||52 dba|
|Water Tank Capacity||2 gallons|
The best TOSOT dehumidifier with pump is ideal for continuous unattended use in large spaces. This unit is a 50-pint dehumidifier, indicated for 3000-4500 sq. ft., but users report good functionality in much larger spaces. (Confusingly, the exact same model is sometimes called a TOSOT 70 pint dehumidifier with internal pump in some reviews, but that is because of the 2012 DOE standards.) The 70 pint 2012 DOE specification is common among 50-pint dehumidifier reviews.
Note that if gravity-fed drainage is possible, one of the TOSOT dehumidifiers reviewed below would be more economical for continuous running.
Furthermore, some users have trouble with the internal pump drainage joint. People permanently damage the outlet, as they tend to just yank the green plug out of the outlet. (Proper technique is a simultaneous push and pull motion.) For convenience, this unit comes with a 16-ft. length of white ¼-inch hose for use with the internal pump—you could pump water about 12 ft. directly up, if needed.
If you use this in an occupied area, note that it generates 52 dB(A) on high fan speed. Most users find this relatively quiet, but a few say it is a bit loud on high, comparing it to the sound of a window air conditioner.
This unit, like all TOSOT dehumidifiers, is made to work in a temperature range of 41-90⁰F and a relative humidity range of 35-80%. Also, it is not made to be used in places where it could be submerged in fluid. Therefore, be cautious if using in extreme conditions.
The filter indicator light comes on every 250 hours of use to remind you to clean the filter as needed—for most, this is about every 30 days. The power cord is 6 ft. long. Extensions are not recommended because of insufficient grounding. If you only have a 2-prong outlet, purchase a plug adapter for safety.
2. TOSOT Super Quiet GDN50BA-A3EBA2D
Best TOSOT Dehumidifier for Large Spaces
|Moisture Removal||50 pints per day|
|Coverage||4500 sq. ft.|
|Dimensions (W x D x H)||14.8 x 11.4 x 24.1 inches|
|Noise Level||52 dba|
|Water Tank Capacity||2 gallons|
The TOSOT 50-pint is the best TOSOT dehumidifier for large spaces—an entire apartment, level of a house, or even a whole house. (Again, it is not uncommon to see this called a TOSOT 70 pint dehumidifier in some reviews, using 2012 DOE standards.)
Even without an internal pump, it can run unattended, as long as you keep a gravity-fed drain hose in place. (The gravity-fed connection is on the mid left side, looking from the dehumidifier’s front.) Most people find they can use standard garden hoses, but you can also purchase a small length of ¾-inch hose for the purpose.
Aside from no internal pump, this unit is identical to the one above. The control panel features an LED screen showing the humidistat reading—the target humidity as you set it, and then the actual current humidity in the room. The humidity can be set in 5% increments; users with separate hygrometers find that the dehumidifier’s hygrometer’s error is 3-4%.—negligible for most purposes. If you press the “-“ button below 35% RH, the unit goes into Nonstop Mode, which means it will keep dehumidifying at the current fan speed, regardless of relative humidity level.
Like other TOSOT dehumidifiers, this unit will restart its last settings if there is a power interruption. If the condenser starts to freeze, this unit automatically engages its Defrost Mode—the fan runs without the condenser. If its tank is full or there is a problem, it will automatically shut off. TOSOTs can run according to user intentions, even when unattended for days.
Users are wowed by how quickly this unit can remove moisture—3 pints per hour, maximum. In some spaces, it can get the relative humidity (RH) from 80% to 35% within a couple hours.
3. TOSOT GDN35BB-A3EBA2A
Best TOSOT Dehumidifier for Mid-Sized Spaces
|Moisture Removal||35 pints per day|
|Coverage||3000 sq. ft.|
|Dimensions (W x D x H)||13.7 x 10.6 x 21.9 inches|
|Noise Level||50 dba|
|Water Tank Capacity||1.5 gallons|
The 35-pint is the best TOSOT dehumidifier for mid-sized spaces, such as garages, great rooms, and medium-size basements. (It is recommended for 1500-3000 sq. ft. areas, so if your space is under 1500 sq. ft., consider #4 below.)
This unit is a bit quieter than the large models above, at 50 dB(A) on high and 48 and 46 dB(A) on medium and low, respectively—another feature that makes it best for living rooms and bedroom-bathroom areas.
This unit is a bit smaller in dimensions than the ones above while having the same uniquely attractive aesthetic of all TOSOT dehumidifiers. The exterior is white plastic, and the grille has lens-shaped openings instead of the usual straight rows. Plus, the drain bucket has a thin vertical viewing window on the unit’s bottom front to display the water level discreetly.
There is debate whether it produces a plastic smell at first, as many dehumidifiers do. It looks like you should expect a bit of plastic odor the first day or so of use.
Some users take issue with the swivel casters, arguing that they are really only helpful on solid floors. Fortunately, this particular model is light enough that many users could probably carry it if needed.
4. TOSOT GDN20AZ-A3EBA2A
Best TOSOT Dehumidifier for Smaller Spaces
|Moisture Removal||20 pints per day|
|Coverage||15000 sq. ft.|
|Dimensions (W x D x H)||13.4 x 9.9 x 19.5 inches|
|Noise Level||48 dba|
|Water Tank Capacity||1 gallon|
The 20-pint is the best TOSOT dehumidifier for smaller spaces. If you have a closet, a small basement, or just very small living quarters, this unit is the smartest choice—a larger dehumidifier will only take up unnecessary space and turn on and off quickly as it rapidly reaches the target humidity.
This unit is smallest in dimensions, lightest in weight, and least expensive on this list. Those using it in a small bedroom or bathroom will appreciate that it is also the quietest on this list—only 48 dB(A) on high, and 46 and 44 dB(A) on medium and low fan speeds, respectively.
Like the other TOSOT dehumidifiers, this one has a gravity-feed outlet that works with a garden hose. However, many small space users will just want to empty the drain bucket: the bucket has the same easy-to-use handle and spill-resistant structure as the larger ones above. This model also has the same noticeable but unobtrusive sound alarm to indicate the bucket is full and that the auto-shutoff is going into effect.
Ultimately, this is just a mini version of #2 and #3 above. The thorough video reviewer below demonstrates the use and functionality of this unit. (He says this is a TOSOT 30 pint dehumidifier review, but this is the 2012 DOE standards—it is the same model):

Who Makes TOSOT Dehumidifiers?
The TOSOT brand has existed since 2003. TOSOTDirect, under the auspices of SainStore, Inc., has marketed TOSOT units to the USA since 2018.
This begs the question, where are TOSOT dehumidifiers made? In fact, TOSOT is a brand of the Chinese company Gree Electrical Appliances. Since 2007, Gree has been the world’s biggest manufacturer of air conditioners and air conditioner parts, many of which are produced under other companies’ branding. Gree makes a variety of residential devices, including induction cookers, heaters, and electric fans.
Comparing TOSOT with Similar Dehumidifier Brands
TOSOT vs. Frigidaire
Usually, a dehumidifier by Frigidaire is slightly more expensive than a TOSOT—probably partially because of brand recognition. In addition to a selection nearly identical to TOSOT’s, Frigidaire offers a 60-pint unit, as well as a newly released 50-pint WI-FI compatible one. Overall, Frigidaire dehumidifiers have a similar build to TOSOT’s and get similar user ratings.
TOSOT vs. HomeLabs
HomeLabs dehumidifiers are a slightly better value, as their prices tend to be lower than TOSOT’s, but the warranty is 2 years. HomeLabs has a similar dehumidifier size selection, but they do not have an internal pump option. However, they do offer a mini dehumidifier that can remove 9 oz. of water per day—perfect for dehumidification of small spaces, such as closets, bathrooms, or personal offices.
TOSOT vs. Danby
Danby dehumidifiers are not quite as well-rated as TOSOTs, but accordingly, Danby keeps its prices lower. All the while, it out-competes TOSOT with a few more size/capacity options, black and white color options, 2-year warranty, and 24-hour timer. Most Danby dehumidifiers are Energy-Star rated. However, note that Danby seems to keep using 2012 DOE standards: Its 70-pint is comparable to TOSOT’s 50-pint, etc.
TOSOT vs. Hisense
Hisense dehumidifiers are slightly lower-rated and noticeably cheaper than TOSOTs. However, all Hisense dehumidifiers are Energy-Star rated, relatively quieter, and come with a 2-year warranty. Hisense also has more options and features: Smart options, 2- and 3-speed fan options, black and white colors, built-in pump, and even inverter dehumidifiers. However, coverage figures suggest Hisense units are less powerful.
TOSOT vs. Soleus
SoleusAir dehumidifiers are similar to TOSOTs in price, features, and warranty; however, users seem to rate Soleus lower on general retail sites (Amazon, Walmart)—users claim they malfunction fast. However, buyers on specialized sites (Sylvane, Home Depot) seem to be more satisfied. Soleus units do have some unique features: Child Lock and pre-programmed modes for different room types.
How to Set up & Use a TOSOT Dehumidifier Effectively
TOSOT dehumidifiers should be kept in spaces 40-90⁰F in temperature. When running, the dehumidifier should be on a flat surface and have a surrounding clearance of 18 inches; the intended area should be well-insulated for best results.
Read the TOSOT Dehumidifier Manual for best use, but there are also TOSOT video demonstrations. Among other things, the manual decodes the various malfunction codes. (For example, the TOSOT dehumidifier “fo” code on the digital display means a disruption to the compressor-evaporator system.) Sometimes, the solution to an apparent malfunction is to transfer to a more moderate (RH or temperature) environment or turn up the fan speed for better ventilation.
50% RH is arguably the best setting for a living space—dry enough to prevent mold and mugginess but humid enough for healthy skin and sinuses. If needed, gently clean the tank and exterior with soap and water. It is okay to put vinegar in the tank if mildew is a real concern. Dry all parts out before storing.
People Also Ask (FAQ)
How do you clean a TOSOT air dehumidifier?
Clean the removable filter whenever you see the indicator—with vacuum, or if needed, detergent and water. Add vinegar or AC tablets to the tank to prevent mildew, especially if the internal pump is running. (The pump maintains a certain level of water standing in the tank.)
Why is my dehumidifier running but not collecting water?
If it is turned on but does not run, it could be shutting off because the environment is already at the set humidity. Otherwise, if the dehumidifier is running but not removing moisture from the air, there is likely a compressor problem. Alternatively, if the room is very cold, the unit could be running in Defrost Mode—running with fan only and frequently shutting off. (You can tell this is happening if the output air is cool—expected dehumidifier output is warm.)
How do I empty my TOSOT dehumidifier and how often?
Every 5 hours is the reported maximum for manual pouring out of the drain bucket, but in most environments, you can probably go longer. Do not worry about overflows since TOSOT units reliably shut off when filled.
How long should a TOSOT dehumidifier last?
A few users have them quit fast, before the warranty period is up, but most find they last 3-5 years.
Do TOSOT dehumidifiers use a lot of electricity?
Most users are satisfied with the power usage. TOSOT dehumidifiers are Energy-Star rated, so they are competitive in this area.
How much do TOSOT dehumidifiers cost?
Generally, the smallest model (#4 in this review) is around $175, while #1 (the one with the internal pump) is closer to $300. The others fall in between, with #2 (without internal pump) around $240.
Where can I buy TOSOT dehumidifiers and replacement parts?
While Walmart offers some TOSOTs, Amazon and Home Depot offer the full range of TOSOT dehumidifier models at lower prices. (Amazon and Home Depot more or less tie on costs—it depends on when you buy and which model you get.)
TOSOT dehumidifiers are suitable for a variety of spaces and situations. However, the TOSOT 50 pint dehumidifier with Internal Pump (#1 in these TOSOT dehumidifier reviews) is the overall best bet. TOSOTs are affordable, simple to use, and have all the necessary features most residential users want.
