2025 ENERGY STAR Dehumidifierd: Removes 35 pints per day (AHAM standard) and up to 70 pints in saturated conditions. Perfect for spaces up to 1,000 sq. ft.

Automatic Defrost System: Our advanced auto-defrosting system continuously monitors ambient temperature using built-in sensors. When low temperatures are detected, the unit automatically initiates a defrost cycle to prevent frost buildup. During this cycle, the compressor pauses while the fan continues to operate, allowing the frost to thaw. Once complete, the dehumidifier resumes normal operation. This feature conserves energy and helps extend the unit's lifespan.

Full-Featured & User-Friendly Design: Designed with the modern user in mind, this professional dehumidifier combines powerful performance with thoughtful details. The efficient auto-defrost function enables reliable operation in low-temperature environments. It operates quietly at less than 52 decibels and features an auto-restart memory function. The intuitive control panel makes operation simple and straightforward.

Built-In Protection & Filtration: Equipped with a MERV-1 pre-filter that captures large particles (down to 10 microns) to protect the unit's vital internal components from dust during operation. This helps maintain performance and longevity while ensuring the output of fresh, dry air. (Note: For comprehensive air purification of smaller particles, a separate air scrubber is recommended.)

5-Year Warranty & Safety Certified: This dehumidifier is ETL-certified, fully compliant with electrical safety standards. Every AlorAir dehumidifier is backed by a 5-year limited warranty, supported by a professional customer service team ready to assist you at any time.

Why Use a Dehumidifier?
There are several important reasons to use a dehumidifier. Firstly, it effectively reduces indoor humidity, preventing the growth of mold and bacteria, which thrive in high-humidity environments and can lead to respiratory problems and other health issues. Secondly, dehumidifiers improve indoor air quality by reducing the number of dust mites and mold spores, which is particularly beneficial for individuals with allergies. Additionally, dehumidifiers protect furniture and indoor decorations from moisture damage, preventing wood from rotting and metal from rusting, thereby extending the lifespan of items. Improving living comfort is another major benefit, as an appropriate humidity level can make one feel cooler or warmer, reducing the discomfort caused by excessive moisture. Lastly, dehumidifiers help save energy because high humidity makes air conditioning systems work harder, increasing electricity consumption, while proper dehumidification can improve the efficiency of the AC and reduce energy use.


In Which Scenarios is a Dehumidifier Needed?

  • Basement: Basements are prone to moisture buildup due to their lower position in the house. A dehumidifier can prevent mold growth, protect stored items from dampness, and avoid the unpleasant musty smell often found in basements.
  • Crawlspace: Crawlspace areas often suffer from high humidity due to poor ventilation and proximity to the ground. A dehumidifier is essential in these spaces to prevent mold and mildew growth, protect insulation and structural materials from moisture damage, and maintain a healthier indoor air quality for the entire home.
  • Bathroom: After showering, the humidity in the bathroom significantly increases. A dehumidifier can help quickly dry the air, reduce condensation on bathroom walls and mirrors, and prevent the growth of bacteria in tile grout.
  • Clothing Storage Area: In moist environments, clothing is susceptible to mold and odors. A dehumidifier helps keep clothing dry, prevents damage to valuable textiles, and reduces the need for frequent drying of clothes.
  • Study or Storage Room: Books, documents, and collectibles are highly sensitive to humidity. Excessive humidity can cause paper to deteriorate, fade, or become structurally damaged. A dehumidifier helps maintain a dry environment, prolonging the preservation of these items.
  • Kitchen: The kitchen experiences significant changes in humidity, and a dehumidifier can help control moisture levels, prevent food spoilage due to dampness, and reduce the likelihood of mold growth inside cabinets.
  • Bedroom: Maintaining an appropriate humidity level in the bedroom is crucial for a good night's sleep. A dehumidifier can reduce the moisture in the air during the night, providing a more comfortable and healthier sleeping environment.
  • Gym: Exercise produces a lot of moisture, and a dehumidifier can help keep the gym environment dry, prevent equipment from being damaged by dampness, and enhance the workout experience.
  • Office: Using a dehumidifier in the office can boost work efficiency as a dry environment helps maintain employee comfort and focus, while also protecting electronic equipment and important documents from moisture.
