Of course, you can’t expect one of the best 70 pint humidifiers to not have an array of safety features, as well.

Considerations For Basement & Large Area Dehumidifiers – Buying Guide

Best Large Area Dehumidifiers
Vremi 4,500 Sq. Ft. Dehumidifier

Now that you have had the opportunity to browse through all our reviews of dehumidifiers for basements, have you decided which one is the right for your home?

If not, then there’s no need to be concerned. For this exact reason, we’ve decided to take it upon ourselves to create the following comprehensive buying guide.

This guide will take you through each step of the selection process to ensure that by the time you’re finished reading, there will be no doubt which is the perfect appliance for you! Get ready to have healthier, fresher air in your home!


First, it’s a good idea to know the size of the area you’re going to be using your dehumidifier in. This is so you can figure out the capacity that you’re going to require.

As you may have noticed, those on our guide have a 70 pint capacity, which means it can get rid of 70 pints of excess moisture in a room per 24 hours. These are ideal for basements, which is why we’ve included them on our list.


All dehumidifiers come with a kind of collection area or tank, though some will come with an included drainage hose or at least the option to add one on later.

These are very similar to your regular garden hose and work to transport the collected moisture into a floor drain. If you don’t use one, most quality products come with an auto shut-off feature that will turn it off once the tank becomes full.

However, this also means that you won’t be able to operate it non-stop, and will only turn on once you’ve emptied it out.

Keep in mind that a pint weighs approximately one pound, so while a large capacity dehumidifier can collect up to 75 pints a day, tanks generally hold up to three gallons to allow for easy, frequent emptying though this is going to be challenging if you’re not incredibly strong.

Noise Level

When it comes to any kind of appliance in your house, you want to consider how much noise is creates.

Dehumidifiers create a noise similar to the hum of a window air conditioner though the bigger the capacity the louder it’s almost always going to be.

Most will give out around 53 decibels though some can go up to and over 65 decibels which is relatively noisy. If you really want to keep noise down, make sure it’s sitting on a level surface or has leveling feet that will do the job for you.

Digital Controls

You may have noticed that each machine comes with a different set of controls along with a different type of display screen.

You probably want to have the most control possible over your machine, to provide the best results for your home and your lifestyle. Some are very easy to work with and let you quickly change the desired humidity percentage up or down with a simply press or touch of a button.

Others are a bit more complicated, though this is only usually the case in less expensive models. You’ll probably also like to have automatic options that will let you just set it to your desired level and go – no need to keep checking in or babysitting it!

Energy Costs/Consumption

Did you know that it costs around $15 to $50 per month just to run a large capacity dehumidifier like those seen on our guide? Of course this does vary a bit depending on how much you use, the size of your basement, and the humidity levels.

Despite this, we always highly recommend purchasing a model that’s certified by Energy Star, as they’re the most energy efficient and can even let you save up to 30% on energy consumption over non-certified machines!


How much are you willing to spend on one a good crawl space dehumidifier? It’s a good idea to create a budget for yourself before you start looking so you don’t accidentally spend more than you’d wanted to.

No matter what your budget is, we can assure you that we have an excellent selection that will fit it. Just keep in mind that if you do have the means of spending a bit more, it often pays for itself in one way or another.

When you go up in price, you’ll find that models are often comprised of higher-quality materials and with more care which will usually end up lasting longer than cheaper ones anyway.


When it comes to household appliances, warranties are crucial to have. You want to be able to purchase with confidence knowing that it’s going to work properly and that the money you’ve invested hasn’t or won’t go to waste. Warranties do vary quite a bit, with the minimum typically being 60 days and the max around 5 years or more.

FAQs About Crawl Space Dehumidifiers

Q: How big of a dehumidifier do I need for my basement?

A: You first need to measure the dimensions of the room or home in question. If you’re going to be addressing a space 2,500 square feet or larger, it’s just best to opt for a whole-home dehumidifier. Also, consider the level of humidity in your basement.

  • For a space that’s 500 square feet (46 m2), a dehumidifier with a 10 US pt (4.7 L) capacity should work.
  • If your space is 1,000 square feet (93 m2), get a 14 US pt (6.6 L) dehumidifier.
  • For a 1,500 sq ft (140 m2) space, get a 18 US pt (8.5 L) dehumidifier.
  • For a 2,000 sq ft (190 m2) space, get a 22 US pt (10 L) dehumidifier.
  • For a 2,500 sq ft (230 m2) space, get a 26 US pt (12 L) dehumidifier.

Q: Do I need to run dehumidifier in basement in winter?

A: This will depend on your individual home and environment. As a general rule, it’s recommended that you keep using your dehumidifier so long as humidity levels are 50% or above. However, if you live in a particularly warm or humid environment year-round, then you should also use the dehumidifier year-round.

Q: Will a dehumidifier in the basement help the whole house?

A: Typically, yes. As humidity can seep through the floors/ceilings, it can have a huge influence on the overall humidity levels in your entire home, as well as the cleanliness of the air.

Q: Will a dehumidifier help with basement smell?

A: High-quality dehumidifiers like those that we’ve covered on our guide will help to greatly reduce and/or eliminate foul odors completely, just like that of “basement smell”.

Q: Where in basement should I place dehumidifier?

A: Most people who are dealing with relatively mild humidity are best off placing it in a central location. They operate best when they’re in closed areas, and you should have at least a foot of space around the coils to allow air to flow freely.

Q: Will a dehumidifier kill mold?

A: No. Dehumidifiers do not have the capability to actually kill mold, though they can help to prevent it from growing due to humidity levels/moisture.

Tips For Choosing Dehumidifiers

#1: For extra savings, make sure to find a dehumidifier with an easy-to-clean filter.

Instead of having to purchase replacement filters or deal with the hassle of all of that, simply go for a model that has filters that can just be washed out under the faucet. Eco-friendly and budget-friendly!

#2: If you’ll be using the model in various parts of your home, make sure it’s easy to transport.

Take this extra seriously if you’re not going to be using a drainage hose! These will feature attached wheels on the bottom to glide them from room-to-room, and handles so you can carry them if you’d like.

#3: If you’ll be using it in colder temperatures, make sure the dehumidifier comes with a kind of anti-frost feature.

This feature makes sure that it can operate and won’t freeze or jam up in lower temperatures. Usually, the lowest temperature you can operate them in is 41 degrees Fahrenheit.


Now that you’ve had the chance to read everything you could ever want to know about the basement & crawl space dehumidifiers, which one will you be using in your home? If you’re still unsure know that no matter which one you get, you’ll be receiving one of the best available.

However, what’s most important is that you select the perfect product for you and your home. We hope that our guide has helped you do just that. Thanks for tuning in and we’ll see you again soon!
