Best Dehumidifier for a Piano Room [Comparison of Top 5 Picks]

Do you desire a dehumidifier for your piano? Pianos, as we all know, have a lot of wooden frames. Manufacturers of pianos have not ignored modern technologies and have created numerous varieties of pianos throughout the years to increase quality and cut costs.

The reality is that no other material, natural or manufactured, has yet been discovered that can compete with wood from a range of tree species in delivering the best sound quality.

The biggest issue with wood is its porous nature, absorbing water from the air when humidity levels are high and releasing it when humidity levels are low. As we know, exposing wood to dry and moist conditions causes it to expand and compress, warp, and even split.

In the case of a piano, this might cause issues. The piano’s wooden soundboard is not flat but features an arch known as a “crown.” Changes in moisture content cause the crown to swell or shrink somewhat.

It causes the tension on the strings to shift, causing the piano to become out of tune. The more severe the variations and the more often they occur, the more probable the soundboard will need reconstruction or the whole instrument replaced.

Significant changes in humidity can also impact other wooden elements of your instrument, so don’t worry about it. All piano specialists will agree that extreme variations in humidity are hazardous to the piano, so the humidity should be constant.

How To Control The Humidity of A Piano Room?

The optimal relative humidity for a piano is 42 percent, and most piano manufacturers recommend a humidity range of 40 percent to 50 percent.

That range may not be possible in some cases because most experts think it is more vital to minimize the interval in which humidity varies than it operates within the specified lower and upper limits. In other words, keeping humidity within 50-60 percent is preferable to 40-55 percent.

It is not enough to use a piano dehumidifier; you must also use a piano humidifier. A relative humidity level that is too low is equally as dangerous as one that is too high.

Best Dehumidifier for a Piano Room: CLEVAST 35-Pints Dehumidifier

The Clevast 3,000 sq. ft. 35 pints dehumidifier improves the air quality in your house and maintains a safe and healthy atmosphere.

One aspect to consider is the size of your piano room. This device is designed for medium to large rooms up to 3,000 square feet and can absorb 35 pints (50 Pint 2012 DOE Standard) of water per day between 410F and 900F, and 35% (RH) and 88% (RH).

It absorbs moisture effectively and is ideal for a basement, piano room, living room, bathroom, bedroom, garage, stockroom, laundry, and crawlspaces. It is healthy to maintain the humidity between 45% and 65%.

The device is convenient and easy to operate. You may set the desired moisture level and let it run constantly for 24-hours or until the water tank is full. The indicator will turn On to alert you when the tank is full.

If you don’t realize when the 1.6-gallon tank fills, the appliance will effect an “auto-shutoff” technology that will instantly shut down the unit to avoid overflow.

You can set up and operate this dehumidifier with its simple control panel. When it reaches a particular time or temperature, it will shut off automatically.

It also has an auto-defrost function. The auto-defrost feature significantly prevents machine damage caused by ice from the collected water and provides 24-hour continuous dehumidification, which is fantastic.

When frost accumulates on the evaporator coils, the compressor cycles off, and the fan continues to run until it disappears.

The CLEVAST dehumidifier has 360-degree castor moving wheels for easy movement from one location to another. The recessed handles provide support when carrying the equipment around the room or building.

It has a detachable water tank for easy emptying and cleaning. Just remove the drain bucket and empty the water. To clean the container, fill half of the bucket with clean water and add a small quantity of mild detergent. Twirl it around in the bucket, then empty and rinse it.

If you opt for the automatic draining option, you can attach a drain hose to the outlet for gravity-fed uninterrupted draining.

You must clean the dehumidifier regularly if you want it to function safely and efficiently. Clean the tank every few weeks and wash the filter monthly, but ensure the filter is dry before re-installing. Moreover, a washable filter maintains air quality without costly replacement parts.

It also has soft-touch buttons, an adjustable digital humidistat, and a 24-hour timer for accurate humidity management.

The CLEVAST 35-pint is certified by Energy Star as environmentally friendly, safe, and energy-efficient. CLEVAST offers a 1-year warranty and lifetime support.

Before you begin the operation, make the following checks:

  • Make sure you connect the device to a power outlet.
  • Check that the drain bucket is in the correct position.
  • Ensure that the filter is in place.

Feedback from Users on CLEVAST 35-Pints Dehumidifier After Using for Piano Room

These are feedback from verified purchases only.

1. It reduced the humidity quickly

A customer purchased this appliance for a room not up to 1400 sq ft. He complained that there is just one HVAC unit in the attic, and the humidity level in the summer is up to 70%, which is hazardous to the structure of a building and human health.

Luckily, he saw this product on the list of the most energy-efficient dehumidifiers in 2021, compiled by Energy Star. It has one of the best efficiency ratings for a standalone dehumidifier.

Although the coverage area of the house is not up to 3,000 square feet, he wanted a unit that would function quickly and efficiently to lower the humidity level.

The normal range for the summer is 50% – 55%, and this appliance pulled it there quickly. He decided to position it in an open place downstairs near the stairs, in the same room as the HVAC, its return and offset from the top of the stairs.

It influenced the entire house, especially the two bedrooms in the upstairs with closed doors. He tested it by moving a compact hygrometer around the house and monitoring the humidity level on a thermostat.

On the 25th of May, while operating the dehumidifier, the air was dry within a few hours. He explained that in the first few days of running it on Turbo mode, there was a significant reduction in humidity, and as a result, he emptied the container up to three times per day.

The disadvantage of this, or any dehumidifier, is that it releases heat, particularly in Turbo mode. Once the humidity is at 55% or below, put off the turbo mode and adjust the settings manually to maintain it in the correct range.

During the low humidity days, adjust the settings to Comfort mode. In all honesty, you will never regret buying this unit.

2. Super helpful for multiple household uses and keeps moisture out

Another customer from Washington purchased this appliance for two primary purposes. The first is for exterior storage shed with insulation but not completed with drywall. It is damp during the rainy season.

He has furniture and other important stuff in the storage shed because he moved into this house not quite long. The unique part is that this appliance has an option that automatically controls the humidity to maintain it at an appropriate level.

You may also modify the humidity setting manually to reduce it to 35% for dryer air when it rains.

The second unit is inside the house to function as an air conditioner in the summer. So, he relied on an evaporative air cooler, which emits moisture and makes the room wet when it is running to chill the air. As the place gets damp, the evaporative air cooler becomes ineffective. 

Purchasing this dehumidifier is a good investment. In terms of loudness, it is similar to running a standard fan. If you use it in tandem with an evaporative cooler, there is almost no background noise interfering with phone calls. It is a quality product to recommend.

How To Select The Best Dehumidifiers For A Piano Room?

Piano dehumidifiers and humidifiers are generally used in this situation since they manage the humidity around a piano. They are common household appliances.

If you reside in a region where lower or higher relative humidity is the norm, you will only need one of these machines. Nevertheless, for most individuals, a piano dehumidifier will be required during the humid periods of the year and a humidifier during the dry season.

Let us now look at features you should consider when buying the best dehumidifier for a piano room.

1. Type

There are three types of dehumidifiers available for purchase. The most popular type is the condensing dehumidifier, which draws absorbed air through refrigerated coils and cools it sufficiently to condense and extract the moisture.

Other types are the desiccant dehumidifier and thermoelectric dehumidifier.

The desiccant dehumidifier applies a water-absorbing substance in its operation. The thermoelectric dehumidifiers operate with charged plates. These two types are not as effective as the condenser model, so we can’t recommend them here.

All the dehumidifiers on this list are condensing dehumidifiers.

2. Capacity

A dehumidifier’s capacity in pints refers to how much moisture it can absorb each day. The higher the pints of water a dehumidifier removes per day, the larger the space it can handle. Your ideal dehumidifier should take care of the size of the piano room where you want to use it.

The Hogarlabs 3500 sq. ft. 50-pints dehumidifier outperforms in this case with the highest coverage area of 3500 sq. ft and removing up to 50-pints of moisture per day. Next to its performance is the CLEVAST 3000 sq. ft, which removes about 35-pints of water within an area of 3000 sq. ft. 

3. Size of the bucket

The bucket size should not be confused with the pint capacity. This specification shows the volume of water the bucket can retain. The bigger the bucket, the less often it will need to be emptied.

The Midea Cube 20 pints dehumidifier has a sizeable bucket compared to other products on this list. It has a bucket size of 19 liters and can retain a large volume of water, so you don’t have to empty it more often.

4. Type of drainage

There are two types of drainage dehumidifiers. The passive types allow you to drain the water with a hose or remove the bucket and empty it manually. The pump drainage types will automatically pump out the water.

Pump drainage does not rely on gravity to drain water. You can channel the nozzle into a sink or out of the window. These models are more expensive than passive models.

Both drainage systems are suitable for a piano room; it all relies on the proximity to a window and the availability of a sink.

The dehumidifiers listed in this review use both tank and drain hose options to drain the water.

5. Energy Star Certification

It is advisable to check for the Energy Star Certification to guarantee energy savings.

All the products covered in this review are Energy Star certified, so they use less power during operation.

6. Frost sensor

A frost sensor detects ice formation on the condenser coil. The dehumidifier will then turn off the compressor to allow the ice to melt. If it operates with ice on the condenser coils, the parts may be damaged, and the appliance will need to work harder to absorb moisture.

The CLEVAST 3000 sq. ft dehumidifier is the most recommended for this feature.

7. Auto-restart

If the dehumidifier loses power, it will restart automatically and return to its previous settings when power restores.

The HOGARLABS 3500 sq. ft. and Gree dehumidifier outperform other dehumidifiers with the auto-restart function.

They store the previous setting before losing power and use it when the supply restores. 

8. Humidity sensor

With this sensor, a dehumidifier can detect changes in the environment and automatically turn on and, in certain situations, adjust its power appropriately. Units without a sensor operate manually.

Your piano dehumidifier should detect the relative humidity and turn it on or off when it reaches the threshold. This feature is known as a humidistat.

Since you need a dependable piano dehumidifier, it is best to buy from a reputed manufacturer rather than the cheapest; however, you do not need the most expensive.

The humidity sensor function is active in all the dehumidifiers that make up this review.

9. Quiet Operation

The noise level of the dehumidifier for a piano room may be unimportant to some, but it is essential for others. Look for a unit that has been rated as quiet by users.

CLEVAST 3000 sq. ft. is the best dehumidifier when it comes to quietness. With a noise level of 35dB, it has a whispering noise during operation, so you may forget it is there.

Final Words:

A dehumidifier makes your piano room healthier and more relaxing. You’ll need to buy the correct size unit for the room to ensure it can handle the workload. Once you’ve purchased and set up your dehumidifier, you should notice a reduction in humidity levels within a couple of hours.

It is worth mentioning that when the air is humid, we perceive it to be hotter than it is. If you live in a humid area, a dehumidifier may enable you to reduce the temperature of your air conditioner, save you money, and make the room feel less muggy.

In this review, the CLEVAST 3,000 sq. ft. 35-Pints dehumidifier is our top pick for the best dehumidifier for a piano room. We know you will be pleased with this model, whether your piano room is small or large.
