The bedroom is meant to rest and relax. Unfortunately, if you live in a place with high humidity, the house’s heat and humidity can make it uncomfortable to sleep. High moisture levels can become a breeding ground for mold, mildew, and allergens. Left unchecked, your bedroom may turn into a stale-smelling room that brings you allergies and restless sleep.
Apart from hot, humid weather, condensation laden windows are a common occurrence during the winter months. The problem is exacerbated on single glazed windows or older double glazed units where thermal efficiency is much lower. Condensation is caused by the moisture released by breathing and sweating during sleep in the night. As per research, we exhale up to 300 – 500 milliliters of water every day and can sweat out up to 1 liter of water each night (depending on weather).

The warm air inside our homes holds a certain amount of moisture. Since the air becomes cooler overnight, it cannot retain as much moisture and is released on cold surfaces such as window panes, where it deposits as condensation. A dehumidifier extracts excess moisture from the air to help maintain optimum humidity levels by cleansing excess moisture and preventing mold, bacteria, and other particulates from growing. A bedroom dehumidifier runs quietly through the night to avoid disturbing your sleep.
How Dehumidifier Help Remove the Excess Moisture
Dehumidifier for bedroom plays a vital role in improving your indoor air quality. Dehumidifiers help prevent wallpaper peeling, protect home electronics and music equipment, preserve documents, and keep sofas, chairs, and curtains from moisture. A less humid environment in your home helps clothes dry faster, bread and cereals will remain fresh longer without getting stale.
Many dehumidifiers come equipped with an internal hygrometer and automatic control system. The hygrometer monitors the humidity levels and automatically turns on the dehumidifier until the humidity falls within the prescribed limit. This automation ensures that a dehumidifier can tackle condensation virtually automatically while remaining as energy-efficient as possible.
The air expelled by dehumidifiers ranges typically between 3 °C to 6°C warmer than the ambient room temperature. Over time this raises the temperature of the room, which helps prevent condensation and damp patches. It will also keep the bedroom cozy and comfortable during colder months.
Things to Consider When Choosing a Dehumidifier for Bedroom
Right Size: Dehumidifiers are measured in Pints of moisture per day, or PPD, which refers to the number of moisture a dehumidifier removes from the air in a single day. Buying a large-capacity dehumidifier for your bedroom is overkill and may lead to overly dry air. Instead of going for the largest, most powerful model you can find, consider your bedroom’s area or square feet. If you have a small bedroom at less than 180 cubic feet, then a compact tabletop dehumidifier would suffice. If your bedroom surpasses 500 cubic feet or more, you can consider the best 30-pint or 50-pint dehumidifiers as well.
Noise level: When buying a dehumidifier for your bedroom, you should consider the operating noise generated by the machine – especially if you want it to run overnight. Typically a bedroom dehumidifier generates anywhere from 33dB of noise (equivalent to people whispering) up to 40dB – 50dB of noise (equivalent to a normal conversation). Dehumidifiers that utilize thermoelectric or Peltier technology are the quietest. If you have a small bedroom, a dehumidifier using Peltier technology would be ideal as it ensures dehumidification efficiently and quietly. Note that dehumidifiers that run on Peltier technology are quieter, but they also process less air than those with a compressor.
Dimension: Nobody wants to trip over a large unit on the way to the toilet in the middle of the night. Look for a dehumidifier that can be placed on a tabletop out of reach of children. This ensures that you efficiently get effective dehumidification. A tank size of around 2 liters is adequate to ensure that you don’t need to empty the tank every day.
Timer: Using a timer provides precise control over how long your dehumidifier will operate each day. Usually set in 1-hour increments, many dehumidifiers allow you to set from 1 – 4 hour operation times up to 1 – 24 hours. This setting is commonly used when homes are empty during the day or when people are asleep overnight to ensure the dehumidifier does not run for longer than is required.
Ease of use: A dehumidifier that is feature-rich and packed with advanced technology but challenging to operate would not help you. Most dehumidifiers have straightforward controls, and the units with digital displays will share all the vital statistics at a glance.
Display: A built-in humidistat will tell you the current relative humidity and room temperature in your bedroom. It also indicates whether the unit is working to reduce humidity to the desired humidity level.
Maintenance: Look for features such as a drain outlet or a large and easy-to-clean tank so that the machine can provide a hassle free operation. The tank should be easy to remove, and the machine should be easy to wipe clean once every two weeks.
