Quietest Dehumidifier With Pump: TOSOT 4500 Sq. Ft. 50 Pint Dehumidifier

We know noise level is an important factor for some folks when picking a basement dehumidifier—especially if you are watching TV or have a bedroom nearby. So we used researched the decibel levels on a dozen different models, on various speeds. The quietest model we found is TOSOT’s 4500 square foot unit.

Now, let’s talk about noise level. 60 decibels is roughly the level of a normal conversation. This humidifier measured in the 48 to 53 decibel level (depending on the fan speed).

So to be clear: when running, this dehumidifier still makes noise. We haven’t yet found a model that is completely silent AND has the power to dehumidifier a basement. But when compared to other models that max out at 70 decibels, the TOSOT dehumidifier was much quieter by comparison.

What We Liked

• Alarm to indicate full tank.

• Affordable.

• Easy to use, all digital touch panel.

• Power outage settings retained.

• Water level indicated on front of tank.

• Indicator lights for filter cleaning. The maker says you have to clean the filter after 250 hours of use—or roughly, every 11 days.

• Hose outlet to drain into sink or floor drain.

• QUIET!

What’s Needs Work

• Long term reliability could be better. We notice some reports that these units run for a year or 18 months and then quit. That’s disappointing, as other models we tested have longer life spans.

• Alarm is very loud. We like the alarm feature, but it is VERY LOUD . . . especially when it goes off in the middle of the night!

• Hard to connect hose outlet. The hose outlet is recessed inside the unit, making connecting a drain hose more difficult than other similar models.

Budget-Friendly: SHINCO 5,000 Sq. Ft. Dehumidifier with Pump, Energy Star Rated, for Large Rooms and Basements, Continuous Drain, with Wheels, Quietly Remove Moisture Medium – (70 Pint)

Many dehumidifiers with built-in pumps can get rather pricey. Good news: we found this model delivered solid performance . . . at a price that is much easier on the wallet.

Here’s more:

What We Liked

• Large capacity tank. This model holds nearly two gallons of water—that’s more than others we researched for this article.

• Easy to set up.

• Turbo mode to dry clothes. Yes, you can set it in a laundry room and let it rip.

• Settings remembered after power failure.

• Good overall performance.

• LED display screen with easy-to-use controls.

• Sleep timer with two to four hours.

• Simple enough to move from room to room with wheels. 

• Affordable.

What Needs Work

• Heavy. At 43 lbs., you won’t wanted to haul this in or out of a basement frequently!

• Louder than other models recommended in this article.

• Filters must be washed once a month. But that’s rather standard.

• Instructions could be clearer.

• Return air is rather hot (about 130 degrees). This dehumidifier might be best for fall or winter use rather than summer.

• Drain hose is a small, clear tube. That’s smaller than other dehumidifiers we researched, which have larger hoses.

• Fan works continuously. Other dehumidifiers turn off completely when they reach the target level. This one stops dehumidifying, but keeps the fan running. On the upside, this keeps air circulating in an enclosed area like a basement. On the downside, it uses more electricity.

WiFi Smartphone-Enabled: LG PuriCare 50-pint Dehumidifier With Pump

If you’d like to control your dehumidifier with a smartphone app, there are surprisingly few choices in this category. Not many have that feature and even fewer have it with a built-in pump to drain water.

The best bet: LG’s PuriCare. This dehumidifier performs well and features LQ’s SmartThinQ technology. Basically, you can control with an app and it even works with Alexa and other voice-activated hubs.

What We Liked

• No spilling! This tank is the easiest to remove among the dehumidifiers we tried out—thanks to clever design, it slides out with a handle that flips up for easy carrying. Very clever!

• Effective at lowering humidity quickly.

• Includes drain hose. 

• LED display. 

• Clear water tank so you can see the level of water accumulated.

• Full tank alert.

• Washable filter.

• 12 hour timer. That’s longer than other competitors we researched.

• WiFi app.

• Works with Alexa and other hubs.

• Automatically restarts after power outage.

• Designed for basements or rooms up to 2000 square feet.

What Needs Work

• WiFi drops. If the unit loses its WiFi connection, you have to unplug and replug it in to reset this function. That isn’t fun. If the unit is far from your router, it may not connect consistently. But to be fair, that is true for many smart devices.

• Loud! This is definitely not the quietest dehumidifier on the market. That may not be a big deal if it is set up in a basement living room area . . . but might be a deal-killer in a bedroom.

• Fan runs continuously even when it hits the desired humidity level.

• Pricey.

Why Trust Us

We’ve been rating and reviewing gear for families and homes, including dehumidifiers, since 1994. To find the best dehumidifiers, we surveyed the parents who read our books (2.1 million strong!). We asked those who lived in the most humid areas of the country (New England, we are looking at you in the summer) what worked best in the real world. We took those suggestions and then did six hours of additional research to compare features, performance and value. Finally, we interviewed two HVAC professionals to get their insights.

Here’s another key point: we don’t take money from the brands we review. No free samples, no sponsors, no “partnerships.” Our work is 100% reader-supported!
