| Last Updated: December 20, 2021

A dehumidifier is a household appliance that works to reduce the amount of humidity in the air. It helps you avoid a host of problems that come with excess moisture. Some of these include the growth of mold, dust mites, mildew, and harmful bacteria and viruses.

Dehumidifiers make the environment hostile to the growth of the allergens. It saves you money in the long run, in more ways than one. You won’t have to pay for pricy mold removal, and your AC unit will function better, taking a load off your electric bill.

What is a 30 Pint Dehumidifier Best For?

Today’s dehumidifiers can dry off 750ml per day all the way to 70 pints (About 9 gallons). Between these two extremes is the sweet spot, the 30 pint (about 4 gallons) device. They’re ideal for small to medium sized rooms. Most fall in the 40 to 60 decibel range, which is a good for home use. Quieter ones are great for bedrooms and common rooms, especially for 500 to 1,500 square feet.

House basements exhibit higher levels of humidity in comparison to the rest of the home, and will definitely require more powerful dehumidifying options. Dehumidifiers with larger area of effect (between 1,500 and 2,500 square feet are ideal for basement use. They’re louder than normal dehumidifiers thanks to their powerful fans, and this also makes them perfect for the secluded space in the basement. Dehumidifiers are also used in boats, but only when they are moored.

How to Choose a 30 Pint Dehumidifier

Choosing the right dehumidifier can be tricky, especially if you’re new to this category of consumer electronics. Here are some factors you should consider.

Moisture Levels

Get a hygrometer to test the humidity levels in your home. Anything above 50% and you should definitely get a dehumidifier. Buy one that matches the relative humidity in your home. There are guides online to help you assess this.

Square Footage

Identify the amount of space you’re dealing with. You can physically measure your space, or consult the floor plans of your house. Knowing the size will help you identify the right size dehumidifier for you.

Capacity

This is measured in pints or gallons. The larger your space, the higher the capacity you will require from your dehumidifier. Otherwise, you’ll have to keep emptying the tank. You should also factor in the wetness levels in the room. A laundry room or kitchen will require more capacity in comparison to your bedroom.

Now that you know the space you are working with and the capacity you need, the next step is to compare the options available. This can be done from buyer’s guides and reviews. Pick the dehumidifier that best fits your needs for the budget you are working with. Be on the lookout for additional features such as auto-restart and digital controls.

Review

The world of 30-pint dehumidifiers is just a little better because of the existence of the Shinco SDL-30P. Coming in with a 5-star rating for affordability and cost efficiency, it screams value for the bargain buyer. It’s also the smallest on the list, but a small stature doesn’t negate its ability to dehumidify up to 1,500 square feet. Perfect for small homes, garages, and basements, this 30-pint dehumidifier combines all of the most-wanted features into a single unit.

Bottom Line

Although 30-pint dehumidifiers have the unsavory reputation of being underpowered or inefficient, the Shinco SDL-30P debunks the myths. Two adjustable fan settings, an auto restart, and built-in handles offer a 4-star portability rating while whisper-quiet operation means you can put it in junior’s room. It’s one of those purchases that you won’t (and your child) won’t make a fuss about.

Pros

1,500 sq. ft. of coverage

Fan with two adjustable settings

Auto-restart after a power outage

One of the quietest dehumidifiers on the market

Super durable lift-up handles move with ease and conserve space

Cons

Drainage hose and power cord are short

Automatic drainage tube gets clogged easily

Review

The Waykar PD100A 30-pint dehumidifier may not be up to par with the Shinco, but it certainly offers a lot in the way of style, design, and quality. It features a hose that’s more than 6 feet, which is an upgrade from most systems, as well as a humidistat to provide you with the right amount of moisture. Add in 4.5 stars for both cost efficiency and affordability ratings, and the Waykar PD100A is an above-average entrant into the world of 30-pint dehumidifiers.

Bottom Line

If you’ve never used a dehumidifier before, the small tank and poor instructions won’t do you any favors on the Waykar PD100A. However, built-in handles and casters provide a 3-star portability rating, and with a weight under 25 pounds, you can easily lug this unit into the attic or down a flight of stairs.

Pros

Full tank indicator light

Sleek, modern look

Up to 1,500 sq. ft. of coverage

Continuous drainage hose included

Ability to adjust humidistat from 30% to 80%

Cons

Small tank necessitates emptying far too often

Manual is in broken English, making it hard to operate for novice users

Review

If you’re searching for a dehumidifier that’s affordable and surprisingly efficient, the Shinco SDZ-30P should make its way onto your shortlist. Offering a 3.5-star rating for affordability and 3-star ratings across the board for cost and space efficiency, it’s a well-priced unit that can get the job done. With the inclusion of multiple fan speeds and an LED control panel, it’s easy to use no matter what room of the house you’re in.

Bottom Line

Although its bulky construction lends itself to only a 2-star portability rating, the Shinco SDZ-30P is a decent option in the world of 30-pint dehumidifiers. It’s surprisingly lightweight and offers a number of features that other dehumidifiers only wish they had, making it yet another solid option for prospective buyers.

Pros

Multiple fan speeds

Energy Star certified

A 2- or 4-hour sleep time

Up to 1,500 sq. ft. of coverage

Easy-to-use LED control panel

Cons

The auto-defrost feature has frequent problems

A 2-foot drainage hose leaves much to be desired

Tank Capacity: 2.5 Liters

Review

Although it’s not technically a 30-pint unit, measuring in at 34 pints, the Waykar PD160B earns a spot on this list due to its higher coverage area, drainage options, and intelligent control system that’s an outlier in the 30-pint realm. A power outage restart is also a solid feature on this, especially in areas with extreme weather or older homes with aluminum or knob and tube wiring/fuse boxes. It also earns a 3-star affordability rating that pairs with a 4-star cost efficiency rating, which makes this a decent buy compared to other underperforming dehumidifiers.

Bottom Line

While its performance might lag in high humidity areas and short cycling, or turning off and on frequently, can prevent you from a good night’s sleep, the Waykar PD160B is still an excellent choice for basements, attics, and garages. It’s a tad bit on the heavier side, so a 1-star portability rating is a concern, but overall, you won’t find many better dehumidifiers on the market.

Pros

Intelligent humidity control

Full water tank indicator light

30-day money-back guarantee

Up to 2,000 sq. ft. of coverage

Both auto and manual drainage options

Cons

Issues with short cycling

Somewhat poor performance in high humidity areas

Where Should You Place Your Dehumidifier?

This depends on several factors, such as the size of the dehumidifier, its area of effect, and the condition of the room. Find a spot next to a drain or sink. It should also be close to a power outlet, easing your connection process. Place the dehumidifier in a position with enough room for air to circulate – about 6 to 12 inches of space should suffice.

The hose should be directed away from any electrical appliances and outlets. It should also be kept short, to reduce the possibility of accidents.

Keep the dehumidifier away from dust sources such as woodworking equipment or windows that face the street. In smaller spaces, placing the dehumidifier in the middle of the room is advised.

Lastly, always put the dehumidifier in your damp rooms (basement, bathroom, kitchen, laundry room). Using a dehumidifier in the basement is particularly encouraged, since too much moisture could be dangerous for the structural integrity of your basement.

Conclusion

Dehumidification is important. It improves air quality by removing excess moisture and making it lighter and more breathable. It also makes it harder for odor-causing bacteria and mold spores to exist. These require constant moisture in order to thrive. Make sure you have the right dehumidifier for your needs. Remember to check for an ENERGY STAR rating – rated units are up to 15% more energy efficient than unrated ones. With all that in mind, our top recommendation is hOmelabs 1,500 square foot dehumidifier.
