Best Dehumidifier for Wet Carpet After Flood Damage

Water damage or floods is an emergency that needs immediate, proper solutions. A wet carpet or rug is only one of the problems you may face after a water leak or flood in your home. To solve these problems, dehumidifiers are beneficial in drawing out deeply embedded moisture from heavily damp areas. They effectively remove large amounts of water per day if you use the right capacity or size you need. 

A regular household dehumidifier may be enough for drying small rugs and solving less severe damages. However, they may not always be enough to address emergencies. High-capacity dehumidifiers pull excess moisture trapped under carpets and floorboards to prevent further damage. Professional restorers use water damage restoration dehumidifiers along with other drying equipment for a quick and efficient carpet drying process. Below you’ll find the top six heavy-duty dehumidifiers used for this purpose.

Best Dehumidifier For Wet Carpets

AlorAir Storm LGR

ALORAIR Commercial Dehumidifier with Pump

The AlorAir Storm unit can withstand harsh environments with its epoxy-coated coils and waterproof components. You can even use it outdoors or underwater. Due to its compact build, homeowners and professional restorers also recommend it for wet crawl spaces and basements. It is equipped with an auto defrosting system to prevent frost buildup in temperatures as low as 33.8°F. To avoid internal corrosion and freon leakage, AlorAir uses a rare earth alloy tube evaporator, extending the life of the coils and maintaining heat transferability. As a show of confidence in its products, AlorAir guarantees a five-year warranty.

The unit’s onboard display shows the inlet and outlet temperature and humidity, as well as the number of hours the unit has run. The AlorAir dehumidifier also comes with a built-in condensate pump that can discharge water up to 14.7 feet high. The power cord and drain hose can be winded and stored on each side of the dehumidifier to maximize the space. For easy storage and transport, up to three units can be stacked on top of each other.

The AlorAir Storm also has a Smart version you can connect with a WiFi Control App for easy setup and monitoring. It’s not the most powerful in terms of airflow and coverage, but AlorAir is known for its high-efficiency performance in flood repair and water damage restoration, perfect for drying your wet carpet pad and wet furniture. Considering its capacity, the unit may be too heavy to carry around.

• Energy efficient
• Waterproof, robust build
• Compact, stackable design
• Affordable price for its performance
• Coverage area may be too small
• A little heavy for its size

Dri-Eaz DrizAir 1200

Dri-Eaz 1200 Commercial Dehumidifier with Pump

Dri-Eaz is a popular name in the flood and water damage restoration business, so if you’re looking for an effective dehumidifier to dry your wet carpets, then look no further. The Dri-Eaz DrizAir 1200 industrial dehumidifier removes up to 64 pints of moisture under AHAM conditions and up to 145 pints at saturation. With an airflow rate of 227 CFM, it can dry extremely damp or wet spaces up to 12,000 cubic feet. 

The DrizAir is equipped with the Hot Gas Bypass system for quick defrost cycles and efficient operation in temperatures between 33°F and 100°F. On the top of the unit, you can find the electronic touchpad controls with a digital display including the on/off indicator, a job hour meter, a reset function, and the purge button. The digital control panel allows viewing in four languages: English, Spanish, German, and French. 

This rugged industrial dehumidifier is built with strong roto-molded polyethylene that is highly resistant to damage and leaks.Two units can be stacked together for easy storage. It has semi-pneumatic wheels and a rigid handle for support and ease of movement. It also comes with a built-in condensate pump and a 40-feet drain hose to pump out moisture as high as 15 feet. The hose can be wrapped on the back of the unit and the 25-feet power cord on the top for easy storage.

Although it’s a highly effective dehumidifier for large, wet carpets, note that Dri-Eaz is heavy and heavy as a consequence of the rugged design. Without a built-in humidistat, you need to connect it with an external device to monitor and maintain humidity levels automatically. Additionally, in case of a power outage, the settings will reset to default without the auto-restart function built-in. All things considered, the Dri-Eaz DrizAir is not the best value dehumidifier you can find.

• High performance and efficiency
• Rugged, durable build
• Easy to use controls
• Too heavy for its capacity
• No humidistat

Waykar 180PPD

Waykar 180 Pints Commercial Dehumidifier with Pump

Waykar is known for its functional household dehumidifiers on a budget but it also offers a selection of industrial dehumidifiers including this 180-pint unit. It can remove a maximum of 180 pints of moisture per day at saturation and 90 pints per day under AHAM conditions. With an airflow rate of 380 CFM, the highest on our list, it can quickly eliminate moisture in water-damaged areas and dry wet carpets in large spaces up to 7,000 square feet.

This portable commercial dehumidifier features a simple control panel with a clear digital display to change the operation settings. Adjust your ideal humidity level from 10% to 98% RH and set the unit to turn off automatically with the 24-hour timer. The screen displays the current humidity level or your desired level when setting. The auto-restart feature ensures that the unit will automatically resume operation to your last settings in the event of a power interruption. The HGV defrosting system ensures efficient operation at a wider operating temperature range of 33°F to 113°F. The Auto Defrost mode activates and the indicator light illuminates when frost starts to form.

This high-capacity Waykar dehumidifier is built with two large semi-pneumatic wheels and a rigid steel handle for easy movement. It also includes a built-in condensate that can discharge water up to 15 feet up and a 9.84-feet drain hose. When the internal reservoir is full, the pump will automatically activate. If necessary, you can use a longer garden hose and direct it upwards to the sink or out through the window. For manual drainage, just tilt the unit and remove the rubber plug on the bottom to allow the collected water to drain out.

This Waykar dehumidifier is backed with a one-year manufacturer warranty you can extend up to two years when you register the product on the website. Considering its features, perhaps the most attractive aspect of this product is its affordable price. However, you can’t expect the same build quality as the more expensive and popular brands.

• High moisture removal rate
• Large coverage area
• Easy to use controls
• Not the best build quality


COLZER 232 PPD Commercial Dehumidifier

Another budget-friendly dehumidifier brand we recommend for effective carpet cleaning is Colzer. For large commercial spaces up to 8000 square feet, the Colzer 232PPD dehumidifier is one of your best options, removing moisture up to 232 pints per day or 110 pints under AHAM conditions. This is the highest maximum moisture extraction capacity on our list. It is also one of the most powerful with an airflow rate of 353 CFM, second only to the Waykar unit. It works quickly and efficiently for drying and restoring areas after a flood or leak and also for commercial spaces in need of constant humidity control such as workshops, warehouses, restaurants, and office buildings.

Simply set it and forget with the built-in humidistat feature. It allows you to adjust the humidity level between 10% and 98% in 1% increments. It also has the standard auto restart and auto defrost functions to guarantee efficient operation. Furthermore, the continuous draining option provides hassle-free use without your constant attention. Unlike the rest of our picks, it doesn’t come with a built-in pump, only a 6.56-feet hose for continuous gravity drainage.

This high-capacity commercial dehumidifier is built with two large semi-pneumatic wheels, two flexible front casters, and a sturdy bar handle for easy movement even up and down the stairs. However, the COLZER 232 is quite heavy at around 106 lbs. It requires 1400 Watts to run, which is not the best energy efficiency you can get at this capacity. Overall, its affordable price and functionality make it one of the best all-around dehumidifiers for very large spaces. 

• High maximum capacity of 232 PPD
• Large coverage area up to 8000 square feet
• Easy to use controls
• Low price for its capacity
• Low energy efficiency
• Too heavy to move around

AlorAir HDi90

ALORAIR Basement Crawlspace Dehumidifiers 198 PPD

AlorAir is popular for high-efficiency dehumidifiers for crawl spaces and basements. Even without water damage or flood emergencies, these areas can accumulate huge amounts of moisture around the year. To keep humidity at bay, you need a dehumidifier specially designed to handle extreme conditions in these locations. The AlorAir Sentinel HDi90 is one of its smaller dehumidifiers that are suitable for this job. It can remove up to 90 pints per day under AHAM conditions, and 198 pints per day at saturation. With a 210 CFM maximum airflow, it is recommended for areas up to 2600 square feet. Being the only Energy Star certified unit on this list, it is the most energy-efficient dehumidifier, running on as low as 640 Watts per hour. 

This unit features an onboard humidistat where you can set the humidity level from 35% to 90% RH. It samples the air every hour, and if the humidity goes above the set level, the unit will start dehumidifying. The two-digit display screen shows the current humidity level or the desired humidity during the setting. The unit also features LED lights to indicate when the unit is on, when it’s on continuous or auto defrost mode, and whether the compressor is working or warming up. You can also use this remote humidistat for AlorAir models to control settings far from the unit’s placement. 

The Sentinel HDi90 also features the HGV defrosting system for quick and efficient defrost cycles, allowing for low-temperature operation down to 36°F. This ensures higher efficiency which saves time and money on operation. It also comes with a built-in condensate pump for automatic drainage up to 15 feet high and optional duct mounting flanges for easy connection to an existing duct system. 

Whether you need the dehumidifier for water damage restoration or as a permanent solution to humidity in the basement or crawl space, this commercial-grade AlorAir unit performs at a wide range of temperatures. AlorAir protects all its dehumidifiers from corrosion and freon leakage. The five-year manufacturer warranty also applies to this model.

Dri-Eaz Revolution F413

Dri-Eaz Revolution LGR Commercial Dehumidifier with Pump, Industrial, Compact, Crawlspace and Basement Drying

The Dri-Eaz Revolution (formerly Dri-Eaz F413) is a compact commercial dehumidifier packed with even more power than other, larger models. It can remove a maximum of 17 gallons or 136 pints of moisture per day and 12 gallons or 96 pints per day under AHAM conditions. Contrary to its high moisture removal rate, it has below average airflow from 121 to 180 CFM with a large coverage area of 7,000 square feet.

This unit is often compared with our top pick AlorAir Storm for their similarities in build and capacity. AlorAir ultimately won us over because of its efficiency and cheaper cost. However, the Dri-Eaz Revolution is by no means an inferior dehumidifier. It uses a similar LGR technology that ensures quick moisture removal in a wide range of temperatures and humidity levels. It has a built-in humidistat with a real-time inlet and outlet temperature and relative humidity display so you can set your desired humidity level and leave the unit to work. 

Dri-Eaz is built for tough environments, specifically in water damage restoration projects, after-flood repairs, and construction sites. It features rugged rotomolded housing and corrosion-resistant aluminum coils backed by a one-year warranty on parts and labor and a six-year warranty on internal components.

How to Dry Wet Carpet After Flood or Water Damage

Dry Wet Carpet After Flood or Water Damage

The first thing you’ll notice when you have a wet carpet after a flood or water leak is the unpleasant smell that can be hard to get rid of with just regular cleaning. If left unattended for long, the trapped moisture and its accompanying musty smell can cause damage to your flooring and even higher risks of health problems. Dark and moist areas promote mold growth and other common allergens such as dust mites. 

Once you identify the damp area and the root cause of the moisture, it’s essential to find the right solutions to dry and repair your belongings as soon as possible. The first step you can do is to stop more water from collecting in the area. If you have a leak in your home, have it repaired immediately. If the water is from a rain flood or other natural phenomenon, there may not be a lot you can do to stop the water from flowing into the area. In any case, remove the carpets and other items to prevent further accumulation of moisture.

Once the source of moisture is removed, it is important to dry out the area affected within 48 hours. If there is standing water, mop it up or wipe it with a dry rug. Quickly dry the wet carpets with a fan or wet/dry vacuum cleaner. If possible, take the carpet, rugs, furniture, and other wet items outdoors to air-dry. Wall-to-wall carpeting will need a more powerful fan or blower to suck out moisture that has penetrated the wet floor. For serious water damages, you need to hire professional services immediately. 

Household Dehumidifier vs Water Restoration Dehumidifier

Water Restoration Dehumidifier

Household dehumidifiers are an HVAC staple in highly humid regions that need constant humidity control. They come in a wide range of sizes with many different features suitable for every need. However, for water damage emergencies, you need much more than the capacity of these regular residential dehumidifiers. Unforeseen incidents like heavy rainfall and floods or water leaks in the basement may damage your flooring and house structure. 

For severe water damage, professional restoration services use heavy-duty blowers and dehumidifiers that are specifically built for drying applications in after-flood repairs, building maintenance, and new constructions. These commercial dehumidifiers vary greatly in terms of size and coverage but are usually portable and stackable for easy storage, loading up into vehicles, and transportation from site to site. 

Note that these high-capacity devices can take up a lot of space for storage and operation. They are also a lot more costly to run and may not be suitable for regular, everyday use. So for water damage emergencies, it’s probably best to call a specialized water restoration company.

Dehumidifier For Wet Carpet Buying Guide

Choosing a commercial dehumidifier for carpet drying and water damage restoration involves critical decision-making. Among other factors, you must first consider the dehumidifier capacity and coverage that suit your needs the most.

Moisture Extraction Capacity

This is the amount of water the dehumidifier can remove from the environment, measured in pints per day or PPD. Two types of capacities are often indicated in commercial dehumidifiers. The AHAM capacity is the water collected under average conditions of 80°F and 60% RH, as recommended by the Association of Home Appliance Manufacturers. On the other hand, the maximum capacity is the largest amount that it can extract per day at saturation or 90°F and 90% RH. In this article, we included both the maximum and AHAM capacities of each model to show you their full capabilities. 

Industrial dehumidifiers built for water damage restoration typically come with a minimum of 70 PPD AHAM capacity. For heavy tasks, you may opt for a capacity as high as you need. The largest unit among our picks can extract a maximum of 232 pints of moisture per day. In most cases, it’s more important to look at the AHAM capacity to know the unit’s actual performance.

Coverage Area

The area of coverage of the dehumidifier is also important in drying wall-to-wall carpeting inside your home. This is often measured in square feet or cubic feet. For reference, a standard commercial dehumidifier can cover anywhere from 2,000 to 8,000 square feet. Another important feature you must understand is the airflow, measured in cubic feet per minute (CFM). This is the volume of air that the unit can process per minute. A higher airflow rate typically means a larger coverage area, but it can vary between different brands and models. 

Build Quality

Commercial dehumidifiers are usually built with a durable metal casing or heavy-duty roto-molded housing, as opposed to the lightweight plastic found in residential dehumidifiers. This makes them more durable and more likely to survive harsh environments. One helpful indicator of the product’s quality is its warranty policy. A longer warranty period means the manufacturer is confident in the quality and durability of the product.

Extra Features 

Most dehumidifiers, either for residential or commercial use, have extra features like the auto restart and auto shut-off for your convenience. Also consider your drainage options to avoid even more mess up or spilling of the water collected. Some models like those from AlorAir also have an optional remote control and ducting you can purchase separately.

Tips on Using a Dehumidifier to Dry Carpet

When using the dehumidifier, place it in an area with enough air circulation, preferably in the center of the room with the wet carpet. Close all windows and doors and maintain a few inches of distance from the wall, furniture, or any blockage. Most dehumidifiers work best at room temperature but remain functional from 33°F to 100°F. 

At freezing temperatures, always check the coils for frost, even when the dehumidifier defrosts automatically. Operating your dehumidifier in these conditions can damage the unit’s components. If you have fans or blowers in the room, turn them on to increase airflow and help in drying the moisture or melting any frost buildup.

Do not turn on the dehumidifier instantly after turning it off. Wait for at least ten minutes to turn it on again to allow to even out the pressure manufactured when the machine was operating. Turning the unit on instantly after turning it off can also cause damage to its compressor. Many dehumidifiers have a three-minute reset time where it pauses before starting the dehumidification process.

Make sure all flooring and padding are completely dried before reinstalling your dry carpet. Before cleaning the dehumidifier, always turn off and unplug the unit first. Do not pour any cleaning solution directly on the unit. You may also use a vacuum to clean the inside of the machine to remove any dust or debris. Dehumidifiers include an air filter to protect the machine and its components from pollutants in the air. You must clean this filter as well or replace it as needed. Consult your manual for more specific guidelines and instructions. 

When the dehumidifier is not in use, place it in storage until it is needed. First, turn it off and allow it to dry completely. Ensure that the power cord and drain hose are wrapped neatly in their proper places. Some units have a designated area for them. Once cleaned and dried, store the unit in a clean dry space. When transporting from one location to another, make sure each unit is stacked properly.


Whether caused by a natural event such as heavy rainfall and floods or incidents like burst pipes and cracks in the foundation, water damage in your home must be addressed immediately. Wet carpets, furniture, and other items must be dried and cleaned as soon as possible to prevent moisture and musty odors from spreading. Over time, water-damaged carpets can also damage your floors and cause allergies and other health problems. Depending on the level of water damage, you need a dehumidifier with a large capacity for the best quick solution. Professional restoration companies use commercial dehumidifiers that typically come in a portable and stackable design.
