An In-Wall Dehumidifier (as opposed to a Whole House Dehumidifier system, portable dehumidifier, or wall mounted dehumidifier) is one that is built within the wall or wall cavity of an existing property (home, apartment, etc).
The IW25 dehumidifier by Innovative Dehumidifiers is classified as an In-Wall Dehumidifier, which makes it unique to the market.
By being classified as an In-Wall Dehumidifier (or built in dehumidifier), the IW25 is more affordable to install and maintain then a Whole House system, as well as being smaller (thus using less energy), less noisy, and generally more effective because it doesn’t require the assistance or cooperation of the tenant. The control and operation of the IW25 Dehumidifier is handled by the property owner and is virtually tamper proof.
