Best 100 Pint Dehumidifiers (2026)

The DECIUU puts a condensate pump inside a large cabinet, which solves the problem that defeats most big basement installs: there is no floor drain nearby. The pump moves collected water upward up to 16.4 feet, so you can run a small hose to a laundry sink, a sump or an outside wall. The sibling listing without a pump carries an Energy Star Most Efficient 2024 badge, and this model comes from the same family.

The 5,000 sq ft coverage figure is a reasonable claim for a 100 pint machine in a mildly damp space, and it sits below the 6,000 sq ft claims made by some rivals using the same pint count. In a truly wet basement, treat the capacity as a ceiling, not a promise. Against the Bufanli, the DECIUU gives you the pump while the Bufanli leans on its rotary compressor and newer Energy Star year.

Plan the pump route before the machine arrives: use clear tubing that you can see through, route it with a continuous upward-then-down path and secure it so vibration does not walk it loose. Rinse the filter often, since a big blower pulls plenty of dust. Keep the intake six to twelve inches from walls so the compressor can breathe. Weight is the other thing to plan around: a cabinet of this class is heavy enough that you should roll it on its casters rather than carry it, and a full tank adds more.

AprilAire sells the E100 Pro as a whole-house unit, and that is a different category from the portable boxes around it. It is designed to be set up once and left to run, with smart sensing that starts dehumidification when humidity rises above your target. The listing says it is Energy Star Most Efficient and commercial grade.

The practical difference is installation. Instead of a bucket you carry to a sink, the water leaves through a drain connection, and the unit can connect to ductwork for whole-home treatment. That matters if you want dry air in the living spaces, not just the basement floor. Compared with the DECIUU, the AprilAire is the more serious, more permanent machine, and it asks for more planning and often a professional.

Ownership is quiet: change the filter on schedule, check the drain line and let it work. If you plan to move house soon, a freestanding unit may be the better fit. Ask a contractor about the condensate path early, because the drain line, power and any duct tie-in decide the install more than the unit itself.

Bufanli leads with the newest efficiency label in the group and a high-efficiency rotary compressor. Rotary compressors are generally compact and efficient, and the listing says efficiency is up 50 percent over non-Energy Star products. The claim comes from the seller, so verify the certification on the EPA list before you buy.

Its 6,000 sq ft coverage line is larger than the DECIUU's 5,000, which is the kind of claim to discount by a step. The extra quoted area does not mean a stronger machine; both are 100 pint labels. Compared with the DECIUU, the Bufanli gives you the newer label but no pump in the listing, so it needs a floor drain or a lower exit for the hose.

As with any large compressor unit, run it on a hose, keep the filter clean and place it off the wall. A rotary compressor is quieter and lighter than an older piston type, which helps when you move it between corners. Check the warranty terms, since a less established brand is more of a gamble on service. A newer compressor type is no guarantee of long life, so keep the purchase date and the warranty card together. Inspect the hose clamps each spring, since vibration loosens them over a season.

HOGARLABS states its test basis plainly: up to 100 pints at 95 F and 90 percent humidity. That is a hot, saturated condition, so a cool basement will see a fraction of it. The listing describes a continuous mode with a 3.28 foot hose and a DEHU mode where the unit starts and stops on a set humidity target.

The 5 liter tank is the other practical detail. A large basement unit will fill that in hours, which means the hose is the normal way to run it and the tank is only a backup. The short included hose is a small trap: a 3.28 foot length rarely reaches a floor drain, so budget for a longer one.

Against the DECIUU, the HOGARLABS has no pump but offers a clear mode set, and against the Bufanli it is more transparent about test conditions. Wash the filter often and keep the hose sloping down to the drain. The short hose in the box is a minor nuisance with a simple fix: buy a longer length of the same diameter and a spare clamp before you set it up. Keep the exhaust clear of boxes, because a blocked outlet overheats the compressor.

JustSmart bundles a 24 hour timer, three smart modes, a drain hose and a tank at the lower end of the pricing ladder. The listing positions it as a whole-house machine for basements, offices and stockrooms, though a freestanding unit does not treat a whole house through walls.

Its 4,500 sq ft figure is the smallest coverage claim in the group, and that restraint is a quiet plus. Set against the HOGARLABS and Bufanli at 6,000, it is the conservative one. The timer lets you run it during off-peak hours, which can lower the cost of operation if your utility charges more at peak.

Ownership is plain: wash the filter, check the hose and keep the intake clear. Because it has no pump, the drain must be at or below the machine, so put it near a floor drain if you can. Run the timer to start after the evening peak and stop before morning, and compare your electric bill across two months to see the effect. Use the mode that matches the weather, since a wet week and a dry week are not the same job.

Sijipt adds Wi-Fi app control to a 100 pint basement machine, so you can change the humidity target or check status from anywhere. For a basement you rarely enter, an app that tells you the unit has stopped is the closest thing to peace of mind. The listing offers two drainage methods, tank removal or a hose.

Be careful with the details: the brand is new, the app depends on a vendor server and the listing does not name a certification. If the app ever stops, you want the physical panel to keep working. Against the DECIUU, the Sijipt trades the pump and the efficiency badge for connectivity.

Set it on a low platform so the exhaust is not blocked, wash the filter monthly and test the hose connection once a season. Treat the app as a bonus, not a core feature. If the app drops, use the front panel to hold the target, and set a calendar reminder to look at the unit in person each month. A sticker on the lid with the install date makes future troubleshooting easier.
