Using an environmental chamber to control test conditions, we measure the claimed moisture output-the number of gallons emitted daily per square foot. We also gauge how easy a model is to set up and operate, as well as how easy it is to clean. For our noise test, we measure the sound in decibels generated when the units are running on their highest speed to see how quietly they operate. That’s important because you’re likely to run a humidifier in the same room you’re in, such as your bedroom. Because humidifiers run for long periods of time, we evaluate their efficiency by calculating how much energy it requires for the unit to emit a gallon of water into the air. You may want to avoid models that do poorly on this test because they’ll be more expensive to run. Our humidistat sensitivity test measures how accurate the target humidity setting is on the humidifier. This is important for comfort and efficiency. Finally, we test each unit’s moisture output when operated with hard water. We conduct this test because hard water can have a noticeable impact on performance. Keep in mind: Hard water performance does not apply for every consumer, just in places where the water supply contains significant amounts of dissolved minerals. All these test results are compiled into an Overall Score for each model in our ratings. Humidifiers come in two general types: warm mist and cool mist. The process they use differs, but both add moisture to the air. Choosing between them is largely a matter of personal preference. Make sure the model you choose is easy to clean. As we discovered in our clean air tests, humidifiers can harbor bacteria if not cleaned regularly. Get the full story in “Why You Should Clean Your Humidifier. ”Note: There is a third type of whole house humidifier. In duct or furnace humidifiers are the ideal choice if you have a forced air heating system and want to humidify the entire house. They are tapped into the air ducts and plumbed into your home’s water supply, so they usually require professional installation. We do not test that type. Warm mist humidifiers heat water to a boil, then emit the resulting steam. Some warm mist humidifiers include mineral filters that trap water deposits. These filters are not pricey to replace, but they do need changing, so factor that maintenance cost into the equation. Because of the risk of burns, some pediatricians caution against using warm mist units near children. Shop Warm Mist on AmazonThere are three kinds of cool mist humidifiers: evaporative, ultrasonic, and impeller. Evaporative models use a fan to blow air over a wet wick. The cost for a spare wick is around $, depending on the model. Ultrasonic humidifiers use a vibrating nebulizer to emit water, and they usually operate quietly as a result.
