TOSOT 70 Pint

TOSOT 70 Pint Dehumidifier with Pump

Best dehumidifier for large spaces

Continuous drainage feature lets you connect a garden hose to drain the water directly into a sink or floor drain.

1 TOSOT 70 Pint Review

The TOSOT 70 Pint is hands-down the best dehumidifier you can get, a unit designed to remove up to 9 gallons of moisture in one day. Use it for the basement or for the entire house, and enjoy the benefits of its continuous drainage.

Not only you’ll be able to leave the dehumidifier on for as long as you like, but this model also comes with an internal pump. Thanks to this innovative construction, you can just set it and forget it, whether you want to drain the water at the floor or window level.

The pump may not be the strongest; nevertheless, we like that it also comes with a 1-gallon bucket you can use if you don’t have a drain nearby.

Suitable to plug into any wall outlet, this unit also boasts a power outage restart and is Energy Star rated. Furthermore, it has a quiet operation that won’t disturb if you decide to place it in your living or sleeping spaces.

2 hOmeLabs 70 Pint Review

Similar to our best-in-class up to an extent, the hOmeLabs 70 Pint is an excellent choice if you’re looking for the best value for money. It’s ideal for rooms or basements up to 4,000 square feet and boasts a modern design that fits seamlessly in most homes.

An intuitive control panel makes it easy to switch from continuous to controlled moisture removal. A 1.6-gallon bucket with handle gathers all excess water, and you can even connect it to a garden hose for enhanced piece of mind.

This unit doesn’t have an internal pump though, which means you can only drain water through a hose in drains located at floor level.

Various settings give you plenty of control over the quantity of moisture you want to eliminate. For very damp environments, the unit even boasts a turbo mode. Furthermore, a set of wheels make it easy to move around your home.

3 Vremi 70 Pint Review

If you need a 70-pint dehumidifier for a large house or basement but are shopping on a budget, the Vremi 70 Pint could be the one for you.

It packs a wealth of interesting features, and its only downside is that it’s loud. Apart from the annoying noise issue, it’s quite similar to our best-value.

An intuitive control panel lets you choose between continuous operation until the tank is full or controlled dehumidification. It also has a turbo mode, and you can connect a garden hose to its drain for seamless water management.

Capable of removing up to 9 gallons of moisture a day and coming at a great price point, this is a great alternative if you don’t care about noise.

4 Afloia Portable Review

Designed for home use but compact and versatile enough to use in an RV, the Afloia Portable Dehumidifier can gather up to 26 liquid ounces a day. Thanks to its half a gallon water tank, you won’t even have to empty it frequently.

Safe to use in all indoor environments, it’s powered through an AC cable and comes with a built-in auto shut-off sensor that stops the unit when the reservoir is full.

With a noise level below 42 dB, this dehumidifier is also great to use in the bedrooms or in a nursery.

Energy saving and eco-friendly, it will also have a very low impact on both your wallet and the environment. It also comes cheap, and it’s a great alternative for the homeowner shopping on a budget.

1. How dehumidifiers work

Dehumidifiers all work in generally the same way: they use a fan to move air over cold coils that strip the moisture from the air in your room and blow it back into the room. Then, they drip the moisture into a tank that needs to be emptied. But the specific reason for your dehumidifier purchase will determine which one will solve your problem most effectively.

2. When you need a dehumidifier

Many small annoyances caused by humidity can turn into big problems if left alone for a long period of time. You may need a dehumidifier if:

  1. You experience allergies, headaches, or breathing problems only when you’re at home or that worsen when you’re at home.
  2. You notice dampness that damages paint, creates condensation on walls and windows, or that creates a “heaviness” in the air, especially in your laundry room or basement.
  3. You notice mold in your living spaces, basement, laundry room, or crawl-spaces.

Regardless of how severe your humidity problem is, there is a dehumidifier to relieve your home of unwanted moisture. Read on to explore the factors that determine which dehumidifier is the best dehumidifier for your house.

3. What capacity do you need?

Dehumidifiers typically fall into one of four size groups: Small-capacity, medium-capacity, large-capacity, and whole-house. Capacity, in this case, refers to the amount of water (moisture) the dehumidifier can remove from a space in 24 hours. Follow the guidelines below to see how your home’s unique humidity level, the height of your ceilings, and the size of your space determine what kind of capacity you need in a dehumidifier.

  • 10-40 pint capacity dehumidifiers are ideal for spaces with slight to moderate dampness problems and can generally dehumidify between 500 and 750 square feet.
  • 41-55 pint dehumidifiers can cover up 1,000 square feet, and they can handle more severe humidity in smaller spaces with mold, condensation, and staining.
  • 56-75 pint dehumidifiers are ideal for shoppers with large, tangibly damp, or outright wet spaces, and they’re better equipped to handle spaces that are damp enough to have mold problems. These dehumidifiers can generally handle spaces up to 1,500 square feet.
  • 76-pint+ and whole-house dehumidifiers come in portable units like the smaller options, but can also be purchased as an attachment (and supplement) to your current HVAC system. Whole-house dehumidifiers are the most expensive option, but they can dehumidify large spaces with serious humidity, dampness, wetness, and mold problems.

Use the table below to match the square footage of your space and the severity of your humidity problem to your ideal dehumidifier capacity. If you live in a home with above-average ceiling heights (generally, greater than 9-feet tall) you will need to add a few extra pints to the capacity you need to accommodate that extra space.

500 sq. ft 750 1000 1500 2000
Slightly damp (50-65%) 30 pint 40 pint 50 pint 60 pint 70 pint
Moderately damp (65-80%) 40 pint 50 pint 60 pint 70 pint 80 pint
Very damp / wet (80-100%) 50 pint 60 pint 70 pint 80 pint 90 pint

Clearly, some overlap and a certain level of “intuition” are involved in choosing the correct capacity for your needs. When in doubt, it’s best to choose the larger of two models. It’s much better to have a too-large machine working lightly than a too-small machine working overtime to do a sub-par job.

Other capacity considerations

The size of your space, the severity of your humidity problem, and the type of space that needs humidity treatment will help you determine the correct capacity for your needs. Keep in mind that there are pros and cons to investing in different sizes that go beyond your dehumidifying needs:

  1. Portability and weight: Smaller units may be more portable, but you’ll want to check the precise weight on your top models to make sure the difference in portability is significant enough to sway your decision.
  2. Efficiency and cost-effectiveness: Larger units usually get the job done much more quickly while exerting less effort, which may save you money on your utility bill (and replacement units) in the long-run—regardless of how large your space is or how severe your humidity problem is.
  3. Longevity of the product: Smaller units can get the job done, but they’ll work harder to do it. That means that all of the machine’s internal parts will be more stressed for longer periods of time and, as a result, you’ll likely need to replace the unit sooner than you would a larger one.

If in doubt, we recommend erring on the side of caution by purchasing a larger capacity unit than strictly necessary. That way, you get the job done more quickly, efficiently, and reliably.

4. Draining, pumping, or dumping the tank to remove water

As you shop for a dehumidifier, it’s also important to consider how you want to dispose of the moisture that your dehumidifier collects. Depending on the size of your unit (capacity), the level of moisture in the space, and the type of dehumidifier you select, the tank will need to be emptied of water anywhere from weekly to daily. Dehumidifiers feature three primary options for water removal:

  1. Bucket or Tank: Many budget-friendly units feature an easily accessible bucket or tank for manual emptying. You’ll need to check these units regularly to empty them before they reach capacity. If you choose this route, try to select a unit with a tank that features easy-to-use handles, a cover over the tank itself (a splash guard), and a design that allows for easy cleaning. Units with manual emptying features are typically the least expensive—but they also require the most upkeep on your end. Keep in mind that smaller-capacity tanks need to be emptied more frequently. Luckily, most dehumidifiers that require manual emptying also shut off automatically when they reach capacity, and a warning light turns on when the tank needs to be emptied.
  2. Direct Drainage: This feature allows your unit to continue operating without the need to turn it off and manually empty its bucket. However, it requires a floor-level water drain, and the unit must be positioned higher than the drainage point to let gravity do its work. Dehumidifiers with direct drainage systems offer a less maintenance-heavy approach for a slightly higher price tag.
  3. Internal Pump: This feature allows you to position the unit next to or near a sink or window above the level of the dehumidifier itself. The unit will pump the water from floor-level up to the sink or window, so you don’t have to manually empty its tank. This is the most efficient and versatile draining option, but it’s also the most expensive.

Direct drainage units are ideal for those who need to dehumidify their basements and who have a floor-level drain available. Dehumidifiers with an internal pump are ideal for those who need to pump the water upward into a sink or through a window instead of down into a floor drain.

Generally, it is worth it to invest in a dehumidifier with one of these two drainage systems due to the time commitment involved in emptying a tank by hand. If you’re on a budget and are willing to make a trade-off for maintenance time, though, the bucket- and tank-based drainage options are a solid choice.

5. Energy efficiency

Dehumidifiers are an excellent way to strip moisture from a room, but they can also use more electricity (and money) than running a fan or an air conditioner. Dehumidifiers with an “Energy Star” rating have more efficient coils, compressors, and fans than unrated models. Energy Star rated models remove the same amount of moisture as other models but typically use 15 percent less electricity to do so.

If you don’t see an Energy Star rating on a product, look for its energy factor. An energy factor is the amount of moisture removed per kilowatt-hour. The higher the energy factor, the more energy-efficient the product will be—as long as you select the correctly sized unit for your room.

Running costs

Most dehumidifiers cost between 5 and 10 cents an hour to run. On a monthly basis, you can expect to see a $15-40 increase in your electricity bill. To minimize costs as much as possible, choose a dehumidifier with a humidity control and set it at 40-50 percent—higher for basements and lower for living spaces. That way, the unit will only turn on when the room gets too humid.

6. Available controls and settings

Like most tools, your experience with a dehumidifier is made better when it has the features you need to operate it headache-free.

There are a variety of controls available that allow you to personalize the way your dehumidifier works to suit your home’s unique needs.

  1. Timers allow you to pre-program the hours in the day that your dehumidifier will run. Doing this puts control of cost, energy consumption, and noise levels in the palm of your hand.
  2. Humidity controls let you set the percentage of humidity that the unit should maintain. When it reaches the level you’ve set, the unit will shut off and will only turn back on again when the humidity level has increased.
  3. An auto-restart feature allows the dehumidifier to turn itself back on again if the power goes out. This is especially handy for those who are away from home for long periods of time.
  4. Auto-defrost features keep frost from building up inside the unit and lowering its efficacy. This feature is a must-have for dehumidifiers that will be running in cold areas (like basements).

7. Noise levels

Just like other appliances with fans such as the best space heaters or garage heaters, some dehumidifiers are whisper-quiet and some are disruptively loud. To determine how much noise a dehumidifier will make, look at the decibel (noise) rating. Generally:

  • 0-30 decibels is considered quiet. These dehumidifiers are ideal for living spaces.
  • 31-60 decibels is considered reasonably quiet. These dehumidifiers are acceptable for living spaces.
  • 61-80 decibels will feel disruptively loud. Dehumidifiers at this noise level are suitable for basements or less-traveled areas.
  • 80 decibels and higher will be impossible to talk over and should, generally, be avoided.

8. Air filtration

All dehumidifiers come with air filters that help remove bacteria, dust, and other contaminants from the air. Some units come with washable filters, some include replaceable filters, and others still have a built-in air purification system. Each option offers its own pros and cons. Read on to find the option that best fits your needs.

Washable vs. replaceable filters

Higher-end models often offer a washable air filter that functions similarly to the ones on air purifiers. This means a little more maintenance on your part, but the alternative is a dehumidifier with replaceable filters: when they get dirty, you’ll have to spend extra money to replace them.
If you choose a unit with replaceable filters, be sure to replace them regularly. A build-up of contaminants will cause the dehumidifier to run less efficiently and will also increase the likelihood that those contaminants end up in your lungs.

Combination purifier-dehumidifiers

And, if you’re also in the market for an air purifier, many companies offer combination purifier-dehumidifier models. These models are more expensive than a simple dehumidifier, but contain filtration systems that actively trap allergens and contaminants while managing the humidity level in your home. These are the ideal choice when you genuinely need both purification and dehumidifying functions.

9. Buying Tips

There’s a lot to think about when you’re in the market for a dehumidifier, but we’ve put together a list of the basic components that make a dehumidifier worthwhile (must have features), the good-to-have features that will make your unit more satisfying and efficient for a little extra cash, and the great-to-have features that make a dehumidifier truly best-in-class.

Must have features:

  • Pay attention to the capacity of the dehumidifier: 10-40 pints are sufficient for modestly humid 500-750 square-foot spaces, 41-55 pints will cover moderately damp spaces up to 1,000-square-feet, and 56-75 pint capacities are ideal for severely damp and wet environments or those larger than 1,000-square-feet.
  • Find the most energy-efficient dehumidifier within your budget by looking for an Energy Star rating or, for a more budget-friendly option, a unit with a high energy factor.
  • A decibel (noise) rating of under 61 dB is crucial if you plan to place the dehumidifier in a living space. Otherwise, it’ll feel like you’re talking over a vacuum cleaner.
  • Look for a bucket or tank that can be easily emptied and cleaned when it becomes full and that includes a splash guard over the tank if you plan to empty the water manually.

Good to have features:

  • Direct drainage models offer a hose attachment that lets your unit drain water as it accumulates, eliminating the need to empty the tank on a regular basis.
  • A tank with a 60-75-pint removal capacity will cost more but will ensure that you’re covered for larger spaces or when your dampness problems become more severe.
  • Timers allow you to pre-program the hours in which your dehumidifier will run to save on energy costs.
  • Reusable air filters will help you keep allergens out of the air while you manage the humidity and will also save you from the extra long-term cost of replaceable filters.
  • Humidity controls allow you to program the dehumidifier to maintain the same level of humidity in the room. It will only turn on when the humidity needs to be reduced.

Great to have features:

  • Choose a dehumidifier with an internal pump for a versatile and efficient draining option. Internal pumps avoid the need for a floor drain and allow you to pump water to a higher level (into a sink or out a window) than direct drainage systems.
  • Look for a dehumidifier with a noise rating under 31 decibels for the least disruptive and, often, whisper-quiet option.
  • If you’re in the market for the whole package, consider a combination dehumidifier and air purifier to keep your air clean and
  • An auto-restart feature ensures that your unit comes right back on when your power does to keep the humidity at bay.
  • An auto-defrost feature will keep your unit running as efficiently and smoothly as possible—even in cold temperatures—to save you money and keep you comfortable.

Regardless of your budget, the severity of your humidity, and the size of your home, there’s a dehumidifier out there to keep your home safe and comfortable. A properly sized unit with as much energy efficiency as possible will have your house feeling dry and clean again in no time. By keeping the tips above in mind, you’ll have no problem identifying a high-quality product that delivers the results you’re looking for.
