Humidifiers perform an important function in your home. They can help you restore humidity to appropriate levels and can help make your home more comfortable.
A humidifier can help correct dry air in your home. Many whole house and furnace humidifiers are installed in your HVAC system. Other models have a standalone design and humidify smaller areas.
Whole-house humidifiers are mounted in your duct system and have added installation costs. Many people can benefit from the lower costs associated with standalone humidifiers.
