What is an Appropriate Pint Capacity for Your Dehumidifier

Dehumidifiers are useful devices that help maintain the right environment in your space. They get the job done by extracting the excess amount of moisture from the air and maintain it at the optimal level. If you are planning on getting a dehumidifier, We urge you to get the one that is best suited for your requirements to enjoy a pleasant experience.

Dehumidifiers have a capacity to extract a certain amount of moisture pints from the air. So before buying such an appliance, the number of moisture pints in your room that needs to be extracted daily must be determined. We have listed below some useful details to help you out in this regard.

If your living conditions are moderately damp, go for a dehumidifier capable of extracting 10 pints (4.73 l) of moisture for a 500 sq. ft. (46.45 sq. m) covered area. Moreover, it is recommended to add another 4 pints (1.89 l) for every other 500 sq. ft. (46.45 sq. m). Consider a scenario where you have a 1500 sq. ft. (139.35 sq. m) room. Having a dehumidifier with a capacity of 18 pints (8.51 l) would be the optimum choice here.

For rooms where there are very damp conditions, We suggest you buy a commercial dehumidifier capable of extracting 12 moisture pints (5.67 l) per 500 sq. ft. (46.45 sq. m). If the room is larger, it is advisable to add 5 moisture pints (2.36 l) for each 500 sq. ft. (46.45 sq. m).

For rooms experiencing wet conditions, go for a dehumidifier that may extract 14 pints (6.62 l) of moisture per 500 sq. ft. (46.45 sq. m). For any additional area, add 6 more pints (2.83 l) per 500 sq. ft. (46.45 sq. m).

In case your room is suffering extremely wet conditions, We recommend you not to rely on anything less than a capacity of extracting 16 moisture pints (7.57 l) per 500 sq. ft. (46.45 sq. m). In order to cover the additional area, add another 7 pints (3.31 l) for every additional 500 sq. ft. (46.45 sq. m).

Now that you know what is the right pint capacity of the dehumidifier you are going to purchase, you can consider having a look on our reviews of other dehumidifiers depending on your requirements. In this article, we will be only reviewing top 5 small dehumidifiers:

What is my recommended ACH & CFM?

ACH (Air Changes per Hour):

The term ACH refers to air changes per hour. It gives an idea about the number of passages made by the air through your dehumidifier every hour. ACH also tells you how much airflow is required for the appliance to dehumidify the air properly. Some recommendations to help you determine the right ACH are listed below.

Extremely Wet:
In extremely wet conditions, the air is usually 90-100% humid. Standing water or large puddles may also be seen. 6 is the optimal ACH for such scenarios.

Wet:
In wet conditions, the level of humidity is around 80-90%. You may see mildew, mold, wet spots, stains, etc. 5 is the optimal ACH for such a scenario.

Very Damp:
In very damp conditions, the level of humidity is around 70-80%. A mildew smell may be experienced while you may see moisture accumulations on floor or walls as well. 4 is the recommended ACH here.

Damp:
In damp conditions, the air is 60-70% humid and you may experience musty smells and damp feels. 3 is the recommended ACH in such a scenario.

CFM (Cubic Feet per Minute)

In order to compute the cubic feet per minute, multiply the ACH value by the cubic square footage of the space (Height*Width*Length) and divide it by 60 (minutes). The end figure would be the optimal CFM. In case you are unable to find a dehumidifier with the right CFM, We recommend you to use two separate units.

What Is a Small Dehumidifier and Why Do You Need One?

Has the air in your home or a specific room ever felt sticky to you? If it has, it’s because there is a high level of moisture in the air. Whenever the humidity level exceeds 50%, the chances drastically increase for mold or mildew. Additionally, the bacteria can trigger allergy or asthma symptoms. If you haven’t experienced high levels of humidity before, it causes you to instantly sweat. Your clothes will begin to stick to your skin in a very uncomfortable manner. No one wants that!

Installing a small dehumidifier can be the best solution to your problems. A dehumidifier allows you to take control of your environment. But how does it work? Dehumidifiers use a fan to move air over refrigerated coils. This collects moisture from your home’s air before releasing it back to the room. The final product is air that doesn’t make you feel sticky or dry. Your days of humidity are over.

How to Find the Best Small Dehumidifier for you

The size of your dehumidifier is dependent on the humidity level of the room. If you have a room with consistently high humidity levels, you’ll need a dehumidifier with a large moisture capacity. However, if you simply want stable humidity, a low capacity small dehumidifier is appropriate. You must also consider the size of the room. If you have a larger room with humidity, you may want a dehumidifier utilizing a large moisture capacity.

Indoor temperatures are also important factors to consider. Many dehumidifiers in this category have something called minimal temperature controls. This means the machine adjusts according to the present conditions in the room. If you want to control humidity levels in a cool-temperature area, you’ll need to select a dehumidifier that can handle those temperatures. A garage or cellar are examples of these types of areas. Failure to adhere to those temperatures may cause coils in the dehumidifier to freeze up.

Before buying a dehumidifier, you should double check on the product’s specifications. Ensure that it’s the right product for your space.

Things to Consider When Choosing a Good Small Dehumidifier

There are several factors to consider before purchasing a dehumidifier. This includes power consumption, size, user compatibility, capacity, and other features.

Power consumption:

This is important because you will most likely be running your dehumidifier 24/7. The last thing you want is to pay more for energy bills each month. When selecting a dehumidifier, ensure it is energy efficient. Not to worry, many modern products are eco-friendly and will save you money on energy.

Size:

The size of the room must be considered before making a purchase. For example, you may want a small dehumidifier for a bathroom as compared to a larger room. While small dehumidifiers can cover large rooms, they will take a longer amount of time and more frequent emptying to effectively work.

User compatibility:

Modern dehumidifiers attempt to make the controls user friendly. They implement digital controls that help you determine and maintain the desired humidify level. If you simply want a hands on experience, many machines will adjust according to the room’s present temperature. The water collected in the dehumidifier may need to be emptied for particular models, while other models can be directly connected to a hose. This means the water will be drained for you.

Moisture capacity:

Each dehumidifier contains a particular level of water capacity. This is important because you will have to constantly empty the water. If the capacity is small, you can expect this to be regular task.

Design:

The design or aesthetic appearance is probably an important factor in your buying decision. If your dehumidifier is in a visible place, you’ll want it to be pleasing to the eye. Ensure that your product choice is small but modern. Some of the older models look clunky and out of place. The coloring should be mellow and easily blend in with the room.

Advanced features:

If you have a larger budget, you may want to consider extra features. This includes automatic shutdown and timers. While these are not necessary, they offer some convenience. A timer or shutdown feature can save you some power, and ultimately money.

Benefits of a small dehumidifier

A small dehumidifier will do a couple things to improve your home’s air quality. The purpose of a dehumidifier is to lower the level of humidity. As a result, you reduce the chances of mold, mildew, and odors. If you have allergies, a dehumidifier will reduce your symptoms. It does so by circulating the air and filtering bacteria. This circulation also eliminates musty odors from stagnant air.

Have a pet that stinks the house up? Not to worry, a dehumidifier will eliminate the odor and collect your pet’s hairs. A dehumidifier will also protect stored items from water damage. Since the dehumidifier collects water, the storage items will be safe from potential damage. A small dehumidifier will also be extremely portable. This will help if you decide to take the machine to your work or another room.

Our Pick: Eva-dry Edv-1100 Electric Petite Dehumidifier, White

Unheard-of Dryness

Eva-dry Edv-1100 Dehumidifier

Get It On Amazon

Eva-Dry Not High and Dry

Eva-dry Edv-1100 Dehumidifier

Priced under $65, this 8oz dehumidifier by Eva-Dry stays out of the way and out of your ears. It's built with Peltier cooling tech for whisper-quiet operation, and it's still one of the best-selling small dehumidifiers on Amazon.

Why this product is Our No 1 Pick?

We keep coming back to this one because it nails the basics: it’s genuinely quiet (Eva-Dry lists it at 33 dB, well under the ~53 dB average for this type of unit), it auto-shuts off when the 8oz tank is full, and it’s simple enough that you plug it in and forget about it. Amazon currently lists it as an Amazon’s Choice pick in this category.
It’s priced under $65, which is reasonable for a name-brand thermoelectric unit with this kind of track record.
It’s backed by thousands of Amazon ratings and a 4.1-star average, which is solid for this product category — small Peltier dehumidifiers tend to run lower than compressor units simply because of the physics involved (more on that below).
Low energy draw (about 22.5 watts) means you can leave it running around the clock without worrying about your power bill.

Detailed Review

Noise Level

This is one of the quietest units we looked at. Eva-Dry rates it at 33 dB, and reviewers consistently back that up — several mention it running next to the bed all night without being disruptive, with one owner describing it as “barely audible” even in a quiet room. That’s a real strength if you’re putting this in a bedroom or nursery.

Moisture Removal

The EDV-1100 is rated for rooms up to about 122 sq. ft. — think a bedroom, bathroom, or walk-in closet, not an open living room. Reviewers who size it correctly are happy with it: one owner used it in a 138 sq. ft. bedroom and said they stopped waking up feeling damp and sticky. But we also found reviews from people who tried it in a small RV bathroom with very high humidity and found it couldn’t keep up compared to a larger compressor unit — so treat the 122 sq. ft. rating as a real ceiling, not a suggestion. The auto shut-off and full-tank indicator light are genuinely useful so you’re not left guessing.

User Friendliness

Plug it in, flip it on, and you’re done — there’s no learning curve here. Depending on your room’s humidity, expect to empty the tank anywhere from every couple of days to about once a week. At 6.5″W x 5″D x 11″H it’s small enough to tuck into a corner or set on a dresser without it being an eyesore.

More Factors

The one thing we’d flag: durability reports are mixed. Some owners report years of steady use, while a handful mention the power adapter or unit itself failing anywhere from a few months to a couple of years in — not universal, but common enough in the reviews that we think it’s worth knowing going in. Bottom line: if you need a genuinely quiet dehumidifier for a bedroom, bathroom, or closet-sized space and don’t mind emptying a small tank regularly, this is still our top pick in the category.

Pros

Genuinely quiet operation
Auto shut-off with full-tank indicator
Compact and easy to place anywhere
Low energy consumption
Amazon’s Choice with a strong review history

Cons

Only rated for rooms up to ~122 sq. ft.
Some reports of the power adapter failing over time

Using silica gel instead of a motor, this Eva-Dry is perfect for drawers and closets. It carries a 5-year warranty, is safe around kids and pets, needs no power at all, and is priced well under $20.

Why this product is Budget Pick?

This is, hands down, the cheapest real option on this list — and it’s also one of the most-reviewed dehumidifiers on all of Amazon, with tens of thousands of ratings and a solid 4.2-star average. Despite the low price, it’s not a toy: the crystals visibly change color as they absorb moisture, which makes it obvious when it’s time to recharge, and Eva-Dry backs it with a 5-year warranty.
