Humidifiers are designed to help maintain the comfort levels within your home by increasing humidity levels during the dry heat of the summer months. There are four main types of humidifiers, each of which has a specific method of operation to provide the same benefit to your home. Understanding the different advantages and drawbacks offered by each type of humidifier can help you choose the variant that best suits your home's needs.
Available in either cool or hot mist varieties, ultrasonic mist dehumidifiers work by vibrating a small metal strip within the unit at an ultrasonic speed (hence the name), spraying the water up in a ultrafine mist before moving it throughout the room through the use of a fan. Cool mist varieties can easily cool down a room, while hot mist units can be used to raise the temperature (some units have both capabilities). The main advantage of this type of dehumidifier is the fact that they are extremely low maintenance and don't need to be cleaned or have parts replaced regularly.
Evaporative Mist Humidifiers
Also known as swamp coolers, evaporative mist humidifiers work by drawing air into the unit and over a cold soaked wick or piece of fabric. Some of this water will evaporate into the air, which is then blown out of the humidifier. The main draw of these type of dehumidifiers is that they are excellent at cooling down the air at the same time as they humidify it, which means that they can work in place of or in tandem with your central air conditioning unit. However, evaporative mist humidifiers do need to have their wicks replaced and their interiors cleaned over time to prevent mold growth from occurring, which increases long-run maintenance costs.
Like their name suggests, air washers are designed to 'clean' the air within the room they are installed in, increasing air quality in your home. They work by sucking air into the unit, passing through a series of filters to remove any dust or other particles in the air. The air is then humidified with a cool mist and sprayed out. However, this unique method of operation means that they also require a great deal of maintenance, depending on how much they are used, to clean the filters and ensure continued proper operation.
Steam vaporizers work by superheating water to create steam which is then vented out into the air. By heating up the water used in the humidification process, steam vaporizers help to improve air quality by killing bacteria and any other organic compounds that may be within the water. However, their use of heat limits their effectiveness at improving comfort levels during the summer.
