Humidifier FAQs

A humidifier adds moisture to the air. It works by releasing water vapor or steam into the indoor environment to increase humidity levels. Depending on the design, it may use ultrasonic vibration, warm mist, or an evaporative process. Here's how a humidifier works in most systems:

• Water is stored in a tank or connected directly to a water line.
• The device turns water into a fine mist or vapor.
• Moisture is distributed into the air via a fan or HVAC duct.
• Humidity levels are monitored and adjusted as needed.

There are many types of humidifiers, and the best option depends on your home’s layout, climate, and HVAC system. Whole-home humidifiers are often ideal for larger spaces, while portable units work well in small rooms. Common types of humidifiers include:

• Evaporative humidifiers
• Steam vaporizers
• Ultrasonic humidifiers
• Bypass humidifiers (for ducted systems)
• Fan-powered humidifiers

Learning how to clean humidifier systems correctly is essential for safe operation. Start by unplugging the unit, then empty and rinse the water tank. Use a soft brush and a mild disinfectant, such as a vinegar solution, to clean all accessible parts. Rinse thoroughly to avoid chemical residue. Steps for safe cleaning:

• Turn off and unplug the unit.
• Remove the water tank and any filters.
• Clean all surfaces with diluted vinegar or manufacturer-approved cleaner.
• Rinse and dry before reassembly.
• Repeat weekly or as needed.

Avoid using a humidifier when indoor humidity levels are already high, typically above 50 percent. Excess moisture can lead to condensation, mould, or mildew, especially in poorly ventilated areas. Avoid running a humidifier:

• In warm, humid weather
• In rooms with visible condensation
• Near open water sources or leaks
• When HVAC systems already include humidity control

Besides regular cleaning, your humidifier may require seasonal or annual maintenance. Filters need to be checked and changed regularly, especially in hardwater areas. We recommend keeping a maintenance schedule to ensure consistent performance and long-term reliability. Typical maintenance includes:

• Cleaning mineral buildup
• Inspecting float valves and hoses
• Changing evaporative pads or filters
• Testing electrical components and safety shutoffs

Knowing where to place a humidifier helps maximize coverage and efficiency. For portable units, position the device at least two feet off the ground on a hard, flat surface. Avoid placing it near curtains, electronics, or air vents. Central humidifiers are installed directly into your HVAC system and distribute moisture through the ductwork. Best practices include:

• Keeping the unit in an open area
• Avoiding direct contact with walls or furniture
• Maintaining safe distances from electronics
• Placing it away from sunlight or heat sources
