Top Five Warm Mist Humidifiers

Top Five Warm Mist Humidifiers OnlineAs the most traditional style, warm mist humidifiers deliver soothing warm mist or steam to relieve the symptoms of dry air. The models often use a water boiling or heating technology to convert water into comforting humidity that can help people with asthma, eczema, allergies or just the cold/flu during the dry fall and winter months.

A common problem with warm mist or steam humidifiers is that because they often boil the water, older models can present a safety hazard, but all of these top five warm mist humidifier models correct that problem. Compare each and select the model that best meets your needs.

Best Steam Humidifier Air O Swiss S450


1. Air-O-Swiss S450 Steam Humidifier

As one of the few true steam humidifiers available, the AOS S450 stands heads and shoulders above the field. Not only does it actually heat the water to a full 212°, but thanks to the ClearMist technology, when the steam comes out of the humidifier it is warm, not scalding hot. So while it truly does offer the warmth and hygiene of boiling the water, it is safer than any comparable warm mist humidifier available.

In addition to the warm mist capability the S450 offers an array of digital controls and an LCD display. The built-in hygrostat lets you set your desired humidity level and quickly see current conditions in the room. This model is also one of the most versatile in that unlike other styles, it can safely use any type of water - hard, tap, softened or distilled water all work. Lastly, the Air-O-Swiss S450 has a longer warranty than most other brands, three years.

AirOSwiss U700 Warm Mist Humidifier


2. Air-O-Swiss U700 Humidifier

New to our top five list this season is the Air-O-Swiss U700, the largest, most effective room humidifier in the AOS line. Not only does the U700 have the largest tank capacity of any Air-O-Swiss humidifier model, it will can also output more humidity, up to four gallons, over a 24 hour period than any other warm mist humidifier. In addition to powerful performance, the U700 has the most advanced features of any model including Intelligent Temperature Control (ITC - auto setting), self cleaning mode, timer, auto shutoff, and a sleep mode. You can use the AOS U700 as either a cool mist or a warm mist humidifier. For great output, opt for warm mist.

Like other AOS models, the U700 can preheat water to 176° creating a mist that won't affect the temperature of the room and better disperses throughout your home. Full digital controls, a robust warranty, and the most effective hygiene features make this model the most well rounded choice amongst all humidifiers.

3. Air-O-Swiss 7142 Dual Mist Humidifier

Near the top of the Air-O-Swiss line of humidifiers sits the 7142. With its versatility, performance and features, the AOS 7142 could easily sit at or near the top of any top humidifiers page. When it comes to warm mist, the AirOSwiss 7142 is both safe and reliable. Instead of boiling the water, it preheats it to 176°, and when the vapor is released from this humidifier it measures about 104°.

While this isn't as warm as what comes from the first ranked S450, it ensures that putting this vapor mist back into the air does not affect the temperature of the room. To the touch the mist feels lukewarm, but considering body temperature is over generally 98°, this is normal. In addition to the ability to produce warm as well as a cool mist, the 7142 has an extra large two gallon tank, integrated hygrostat, and a bevy of indicator lights to complement the ITC (read more below), digital display and push button controls, not to mention the fact that the Air-O-Swiss 7142 is nearly silent while operating.

Pure Guardian H7550 Dual Mist Humidifier


4. Pure Guardian H7550 Humidifier

When it comes to style AND substance, the new Pure Guardian H7550 is one of the best warm mist humidifiers available. Not only can it run for up to 90 hours before needing to be refilled, but it has a pre-warm feature that increases efficiency without lowering the temperature in your room. The streamlined, modern design makes it a great fit for any room in your home.

The H7750 humidifier has a few unique features that are a first for the Pure Guardian line of warm mist humidifiers. Like more expensive brands, it features soft touch controls and a digital display. Extension wands allow this model to disperse soothing moisture higher in the room, and the H7750 is demineralization cartridge ready for those who have hard water. Like other dual mist, ultrasonic humidifiers, the warm mist is really only through a pre-warm feature, so when the mist leaves the humidifier it is generally lukewarm. For the features and performance, it's hard to beat the Pure Guardian H7750.

Top Warm Mist Humidifiers


5. Air-O-Swiss U650 Digital Humidifier

The Air-O-Swiss U650 was the first humidifier to feature surface touch controls. Like a touch screen phone or computer, there are not true "buttons" since the controls are smoothly integrated into the sleek control panel. Unique to only the top tier of Air-O-Swiss humidifiers, the U650 features the ITC (Intelligent Temperature Compensation) technology. As with the 7142, this model will automatically adjust the moisture output to create the most comfortable relative humidity for the current temperature of the room. Humidity and temperature are closely related, so this automatic feature will track along fluctuating temperatures and continue to deliver just the right amount of moisture.

As a dual mist model, the U650 can pre-heat the water or simply run as a cool mist humidifier. When set to warm mist, this humidifier emits a lukewarm mist that is safe for use around pets and children. With a full array of features, controls, and hygienic add-ons, the Air-O-Swiss U650 is fully loaded with features.
