The answer to 'how long will dehumidifier last' is that a typical dehumidifier will last 5-10 years with proper maintenance and care. Dehumidifiers are designed for long-term use, but their lifespan can vary depending on factors like the unit's quality, how often it's used, and how well it's maintained.
Higher-quality dehumidifiers from reputable brands tend to have a longer lifespan, often reaching the 10-year mark or more. Proper maintenance, such as regularly cleaning the filters and coils, can also extend the life of a dehumidifier. Additionally, dehumidifiers that are used in less demanding environments, like a dry basement, will generally last longer than those used in very humid spaces.
