Stadler Form Hera Humidifier

As one of the largest humidifiers Stadler Form has to offer, the Hera delivers exceptional humidifying performance all while offering an array of features. Key to the Hera is a large capacity reservoir that holds up to two full gallons of water. This means fewer refills and a longer run time for you. Like the William, Hera is an ultrasonic humidifier that gives you the ability to set your desired relative humidity level or allow for continuous use. With an output of up to three gallons per day, Hera can provide more than enough moisture to relieve the symptoms associated with dry indoor air (itchy, dry skin, coughing, dry sinuses, and chapped lips) as well as help to reduce airborne dust. If an ultra quiet, tower-style humidifier is what you want, look no further than the Stadler Form Hera humidifier.

Customer Q & A

Q1: Why can't I use essential oil in the Stadler Form Hera like I can in the Anton? Isnt' it the same internal machine, of an ultrasonic humidifier? And why doesnt' this have a dual voltage capability like the Anton? I like the Anton, but I need to cover more area and dont' want to run 2 machines.

A: I'm not exactly sure why they suggest the use of essential oils with the Anton. You are correct in that the technology behind both the Anton and the Hera are the same, so it would seem odd that it's ok for one and not the other. That being said, Stadler Form is the only humidifier brand that we've worked with that ok's the use of essential oils with their humidifier Anton. Conversely, every other brand we have carried explicitly says to keep the water clean and free of things like fragrance and essential oils. This is always stated for ultrasonic humidifiers b/c there is some possibility of the added substance eventually gumming up or disrupting the function of the diaphragm that creates the mist. With evaporative, air washer, and even some true warm mist humidifiers, the technology driving the creation of the mist/steam is such that things like essential oils pose very little risk of causing any type of malfunction. So in general, if it's an ultrasonic humidifier, I always advise against the use of essential oils or any substance added to the water. As far as the dual voltage, the only reason I would think why is b/c of where these two products were manufactured. Hera is made in Korea. While Anton is made is China.

Q2: Hera model worked well first year. We just put the unit back into service for the winter dry months. There is a new filter, de-scaled water hardness = 1 degree tank filled with fresh water. Place tank on unit, gurgles and unit runs about 15 min on Continuous opertion AND IT DISPLAYS NO WATER alarm and shuts off. Turn off the unit tip it forward and it runs another 15 min+/-. Anyone have a clue what to do?

A: Take off the water tank and look down on the unit. You will see a screw top. Under that screw top is a white donut shaped piece that is the float. Many times there is calcuim buildup on the stem, and the assembly just needs taken apart and cleaned and put back together. Much of the time, cleaning this assembly can correct the issue. Hope that helps!

Stadler Form Hera Humidifiers

As a tower-style humidifier, the Hera by Stadler Form offers modern convenience and quiet humidifying in an attractive package. With your choice of two colors, the Hera operates at a near silent level and can put up to 3 gallons of moisture back into the air each day to help relieve eczema symptoms, a dry cough typical with asthma, chapped lips, dry skin, a sore throat and other problems that can arise from lack of moisture in your home. With our sample model, I tested the Hera and here is how she compares to other humidifiers.

What I like about the Stadler Form Hera Humidifier

Large Capacity and Effective Coverage - The tank capacity of the Hera is one of the largest of the humidifiers available through Stadler Form - two gallons. For many people this is enough to run for anywhere from 1-3 days, depending on the specific conditions in your home. In terms of coverage, the Hera can tackle up to 760 sq. ft. Generally, I recommend spaces a little smaller than what the manufacturer rates them for, so for this model, I find it works best in areas that are around 550 sq. ft. Again though, this will vary depending on the air flow in your home, how open the space is (open floor plan vs. a lot of doors), and how dry the air in your home is. For most modern homes, the Hera provides enough moisture to help relieve symptoms in larger living rooms/dining rooms and almost all bedrooms.

Quiet - Speaking of use in the bedroom, the Stadler Form Hera ultrasonic humidifier is REALLY quiet. My dog easily makes twice as much noise as this humidifier does at night. When thinking about the noise level, have you ever been in the kitchen in the middle of the night and heard the hum of the refrigerator as the only sound in the house? It's like that, but a little quieter.

Features - Three Settings and an adjustable hygrostat allows you to customize the relative humidity you want, and when it reaches that point, the Hera shuts off. If conditions are particularly severe in your home or office, set it to continuous, and this ultrasonic humidifier will continue to put moisture back into the air until it runs out of water. Don't want to mess with adjusting the settings at night? Use the Sleep/Night mode. This will lower the humidity to an efficient but still comfortable 45% AND dim the display for you. When the water is out, not only can you see it through the smoke colored tank, but an indicator will also let you know on the control panel.

Hygiene - Mineral content in water can be a tricky, as minerals like lime and calcium can form scale and reduce the effectiveness of a humidifier. To combat this, the Hera has a demineralization cartridge that captures minerals and keeps them from being vaporized by the ultrasonic technology. Additionally, there is a small part located in the nebulizer chamber of the humidifier - the Ionic Silver Cube. This little device emits silver ions that help to neutralize microbes in the water tank. Additionally, the ultrasonic vibrations created by this humidifier can actually destroy microbes. All of these things keep the Hera operating efficiently and hygienically.

What I do not like about the Stadler Form Hera Humidifier

Like other ultrasonic humidifiers that bill themselves as "dual mist," the Hera is a bit underwhelming. No ultrasonic humidifier (not Pure Guardian, not Air-O-Swiss, not Vornado or Stadler Form) truly put out a warm mist. Water vapor loses heat very rapidly, so for the moisture coming out of an ultrasonic humidifier to be warm to the touch, it would have to be really hot in the nebulizer compartment. Ultrasonic humidifiers are safer than the older boiler-style humidifiers, so the pre-heat feature in any ultrasonic humidifier doesn't actually warm the water enough to where it feels warm to the touch, as vapor.

The Stadler Form Hera performed well at my house. It kept the bedroom comfortable, and for the low humidity condition in my home, I only had to fill it twice during the course of a week. The design and sleek style blend right in, and with no noise but top notch performance, the only thing I noticed was waking up without a stuffy nose and sore throat. The features of the Hera add value, and while there is some cost associated with maintenance, it's relatively minor and right on par with other ultrasonic humidifiers. Overall, well worth the money.

My son has always had a nagging cough when the weather gets colder, that persists all winter long. The Vornado Humidifier  seems to have helped him feel better, and I don't hear nearly as many late night coughing fits. Thanks!
