LG Puricare Dehumidifier Review

This is a review of the LG PuriCare 50-pint dehumidifier. The 70-pint models have been discontinued in 2019.

During humid summer days, an air conditioner may not be enough to keep your living space comfortable. Finding the best dehumidifier can make all the difference in your indoor environment. It removes excess moisture and unpleasant room odors while reducing the risks of mold and mildew growth due to high humidity. 

If you’re looking to purchase a dehumidifier for your home, the well known electronics company LG offers two options: the LG Puricare 50-pint that has all the standard features, and another 50-pint version equipped with a built-in pump.

In this post we’ll explore the specifications of these two LG models. I’ve done the research and scanned over 300 user reviews across multiple platforms to lay out all the details you need before you make a purchase.

The LG UD501KOG5 and UD501KOJ5 are built with the same exact structure and features. The only difference is the built-in pump and Wi-Fi compatibility of the latter model. From here on, we’ll be referring to the non-pump unit, unless we’re specifically talking about the pump and Wi-Fi capabilities.

Moisture Removal Capacity and Energy Efficiency

The LG PuriCare is rated to remove 50 pints of excess moisture per day under the Department of Energy 2019 test standards. Its capacity is suitable for damp basements and large rooms up to 2,000 square feet. Some top performing 50-pint dehumidifiers like the hOmeLabs can cover larger spaces around twice as much area.

The LG operates in temperatures ranging from 41°F to 99°F, which is the standard for dehumidifiers of its class. It effectively eliminates excessive moisture to prevent the growth of mold and mildew and improve indoor air quality. Users report quick and efficient moisture removal at 50% RH, give or take 2%.

With its Energy Star rating, this LG product is guaranteed to save you money and energy in the long run. Energy Star gives ratings to appliances that meet the energy efficiency requirements set depending on the product category. Most of the highest rated dehumidifiers have this label.

High Quality Construction and Design

This model is fairly new to the market, and it definitely shows in its modern and sleek design that customers like. It stands taller than most dehumidifiers of the same capacity and features an elegant black casing that is made from steel. Perhaps the only other model that can rival the LG model in terms of build quality is the top rated Frigidaire.

User-Friendly Control Panel

LG Puricare Dehumidifier Control Panel

The control panel features a large screen and bright LEDs that show the following functions:

Humidity Control

The LG Puricare 50 pint Dehumidifier has a highly accurate built-in humidity sensor. Set your preferred humidity level using the up and down arrow buttons and the unit smartly adjusts the relative humidity to maintain the pre-set level. The LED display shows the current humidity level from 25% to 90%, and the humidity setting from 30% to 80%, both in 5% increments. 

The unit has no continuous mode. It will automatically stop working once the room humidity is lower than the setting and start back up when humidity rises.

Fan Speeds

Like most standard 50-pint dehumidifiers, the LG has two fan speeds: Low speed, where the air flows at 158.9 cubic feet per minute (CFM), and High speed, at 194.2 CFM. Some users remark that the fan continues to run even when the compressor stops.


You can set a timer from one to 12 hours in one hour increments. Most other dehumidifiers in the 50-pint class have timers that can be set for up to 24 hours.

Auto Defrost

The LG has the normal automatic defrost feature that allows for operation down to 41⁰F. If the unit detects frost on the internal coils, it goes into defrost mode. The compressor stops while the fan keeps running in order to melt the ice. The indicator lights up to let you know when it’s on defrost mode.

Check Filter

The washable filter helps eliminate bacteria and other airborne particles to keep the unit functioning well. An indicator light notifies you when the filter needs to be cleaned. This happens after 350 running hours or 15 days of continuous use. The filter can be accessed on the back of the unit. For optimum performance, clean the filter at least every few weeks. Once you’ve reinstalled it, hold the button for three seconds to reset the hours. 

Bucket Full

The unit features the standard auto shutoff with indicator light and alarm to alert you when the bucket is full. Remove the bucket from the side, empty the water into a sink or drain, and rinse the bucket before putting it back into the dehumidifier. A few negative reviews mention that the alarm sometimes malfunctions and the loud beeping can disrupt sleep. 

Designed for Safety

The LG dehumidifier is designed with some new and unique features that ensure your safety. It has a non-flammable metal frame and an external metal case, as well as heat-resistant glass fiber and silicone wire enclosures. Along with the Airflow Blockage alarm,  this unit has a Safety Standby mode that shuts off  the unit for one hour after 23 hours of continuous operation in order to prevent overheating.

Continuous Draining Option

Even with a collection bucket as beautifully designed as that of the LG PuriCare dehumidifier, it can be inconvenient to have to empty it at least twice a day. Maybe the dehumidifier is in a location you seldom visit, or you’re out of town for a weekend. Having the auto shutoff means the unit will not be dehumidifying when the bucket is full, and during that time the humidity will rise again. 

The best dehumidifiers allow you to automatically drain the moisture collected through a drain hose. If you want to keep the dehumidifier continuously running (for 23 hours) but don’t have the time for manual emptying, you have an optional gravity drain functionality. Just attach a standard drain hose into the outlet found at the back and place the unit near a suitable drain. One downside is the drainage port requires an adapter to connect to the hose.

Additional Features 

What sets the UD501KOJ5 apart is the added internal pump and ability to connect to Wi-Fi. 

Built-in Pump

The built-in pump gives you another option for continuous drainage. It can pump water up into a sink, out a window, or anywhere suitable for you. 

One potential problem with internal pumps is their longevity, based on other brands and models. If one of your main considerations in a dehumidifier is the built-in pump functionality, it may be better to purchase a cheaper model of good quality and a separate, more heavy duty external pump.

Wi-Fi Connectivity

This unit is also SmartThinQ compatible. There is an app you install on your smartphone that allows you to start or stop the operation, monitor bucket capacity, and receive alerts when it’s full. You may also connect with Amazon Alexa or Google Assistant for voice controls. This feature can be extremely helpful for the tech-savvy if only it functioned well. A majority of reviewers complain that their unit does not connect to the Wi-Fi.

LG PuriCare 50-Pint Dehumidifier – Is it Worth the Cost?

The LG is on the higher end in terms of price. If you have severe humidity issues, you can get a higher rated model for a lower cost. But for fans of the LG brand, this portable dehumidifier is still a pretty good deal.

In average room conditions, it can remove moisture just as well as the top-rated high capacity dehumidifiers for homes. These include the Frigidaire and the hOmeLabs 50 pint dehumidifier.

Since this line of LG dehumidifiers came into the market not too long ago, it’s still early to judge the durability and longevity of these models. But if we base it on the high quality build and great features, you can expect a long life given proper care and maintenance.
