Installers build these humidifiers into your home’s HVAC unit. These systems are what your installer will provide when you are considering AC or furnace humidifier installation. They are expensive systems that only work in homes with ductwork and are easy to maintain. There is no risk of accidents because the unit is always out of the way. 

These units heat and cool water before dispersing it into the surrounding air. They are some of the most affordable humidifiers you can find. However, be careful about the placement if you have children or pets to avoid hot water burns.

These are the most common types of humidifiers on the market today. They feature a rotating disc that sends water as a cool mist through a diffuser and into the air. They are the right choice if you want a humidifier for a fairly large room.

These systems are affordable. However, they require regular maintenance to prevent bacteria buildup. Change the filters once they begin to show signs of dirt accumulation.

Evaporators feature a fan that releases moisture through a damp filter and are another affordable option to consider. However, you’ll need to buy one for each room as there is no way to connect them to your air ducts. You should also keep in mind that evaporators are sometimes guilty of releasing too much moisture into the air, leading to mold problems.

Ultrasonic humidifiers are a fantastic choice if you’re looking for a silent humidifier. They feature a vibrating ceramic or metal diaphragm that generates water droplets and a fan that disperses the water into the atmosphere. Ultrasonic humidifiers are low-maintenance units.
