How do I determine what size dehumidifier I need?

Most dehumidifier manufacturers recommend a certain number of pints per square footage. The Ultra Aire MD33 In-Wall Dehumidifier is capable of removing 33 pints of moisture per day, which can maintain the relative humidity in spaces up to 1,200 square feet. Other factors to consider include moisture intrusion based on the tightness of the building envelope, efficiency and design of the HVAC system, and added moisture loads from occupant behavior.

How is an in-wall dehumidifier different than a portable or ducted dehumidifier?

Portable dehumidifiers take up valuable floor space and can be intrusive to residents because of the noise and continuous need to empty the water bucket. Portable units also pose a potential safety issue due to the electrical cord being underfoot.

Ducted dehumidifiers are integrated into the HVAC system and often times cannot be installed in apartments due to the limited space in mechanical closets. These units may also be oversized for the smaller living spaces.

The Ultra Aire MD33 In-Wall Dehumidifier is the best solution, as it is specifically engineered for apartments and hotels. Installed in an interior wall, the unit is unobtrusive to the living space, tamper-proof, and quiet. Since the unit is hardwired and plumbed, it truly is a hands-off dehumidification solution.

How loud is the Ultra Aire MD33 In-Wall Dehumidifier?

The Ultra Aire MD33 has a dBA of 46. To give you an idea of how loud this is, most refrigerators are around 50 dBA and computers are 40 dBA. [Source]

What are the benefits of using the Ultra Aire MD33 In-Wall DEHUMIDIFIER?

Excessive moisture can contribute to poor indoor air quality, property damage, mold, comfort complaints, and reputational risk and liability. Including a dedicated in-wall dehumidifier as an integral part of the mechanical system protects the physical investment and creates a comfortable, healthier living environment for residents.

Doesn’t the air conditioning system provide the dehumidification apartments and hotels need?

Building codes focused on higher energy efficiency result in better insulated, more tightly constructed spaces. These buildings, and the spaces within them, require far less runtime of the air conditioning units, which presents a challenge since these systems typically provide the dehumidification. Less air conditioning run time means less moisture removal and a much greater potential for microbial growth. Extending air conditioning run times to remove excess moisture and control humidity, is not an option if the goal is comfort and property protection.
