Venta Sonic VS205 Cool and Warm Mist Ultrasonic Room Humidifier

Product features:

Full List

The Venta Sonic VS205 Cool and Warm Mist Ultrasonic Room Humidifier features a demineralization cartridge with new nano-silver technology providing microbial protection to help prevent bacterial growth and calcium and lime buildup with no white dust. It uses a high-frequency vibration to generate a micro-fine mist that is then blown into the room by a fan.

As an ultrasonic humidifier, there is no wick like in evaporative humidifiers, which means no moldy odor. Yes, the water tank is difficult to fill as you have to turn it upside down, but the quiet operation of the machine more than makes up for that minor irritation. All humidifiers generate noise of some type, but this one seems to hands-down be the quietest one we’ve reviewed.

Almost all humidifiers are tap water safe; however, the harder your tap water, the more white-dust buildup you will get in the room as well as inside the humidifier. If this happens, simply switch to filtered or distilled water.

The Air-O-Swiss 7144 Ultrasonic Humidifier uses high-frequency vibrations to generate a microfine mist, preventing leaking and/or condensation on the unit. To avoid steam burn, you choose the pre-heating function and the mist then exits the machine at a pleasant 104 degrees Fahrenheit. A replaceable demineralization cartridge (Ag+ Ionic Silver Technology) ensures water mist without lime scale or mineral residues and a quad-band microbial protection system prevents microbial growth in the water base. To completely eliminate white dust buildup, though, it’s recommended to use reverse osmosis drinking water, which also has the added benefit of extending the life of the demineralization cartridge.

Most importantly, the Air-O-Swiss 7144 humidifier is equipped with ITC (Intelligent Temperature Compensation) technology that monitors the temperature to automatically adjust output when conditions change. In other words, this unit measures the humidity and turns on and off based on your chosen preset user selectable setting much like a thermostat does for heating and cooling.

One negative aspect to this unit is that the water tank is undersized and awkward to handle. Once removed, the odd shape makes it difficult to refill and prevent tipping. Additionally, it is nearly impossible to remove the tank without dripping water all over the floor because while installed in the unit, it actually sits in a pool of water; so just be sure to immediately wipe the base of the tank.

Although the tank is difficult to fill, it is equipped with a handle for easy carrying and a full tank will provide up to two night’s sleep free of irritating throat, nose, and skin conditions. Combined with it’s sleek, modern look and it’s state-of-the-art technology, the Air-O-Swiss 7144 Ultrasonic Humidifier is the perfect choice for someone serious about a good night’s sleep and maintaining a high quality of life.

One thing to keep in mind whenever using a humidifier is the type of tap water you have. Almost all humidifiers are tap water safe; however, the harder your tap water, the more white-dust buildup you will get in the room as well as inside the humidifier. If this happens, simply switch to filtered or distilled water.

Crane Warm Mist Humidifier – 1 Gallon

Check Price

Product features:

  • 1 gallon tank with 4.0 gallon output per day
  • Built-in auto shut-off feature
  • Minimum 8 hour running time
  • Medicine cup
  • 2 steam output settings
  • FDA registered

Full List

The Crane Warm Mist Humidifier has two steam output settings to emit bacteria-free steam into the room, a removable, dishwasher-safe medicine cup for steam medication or aromatherapy, and comes in either black or white.

This is a fairly inexpensive humidifier and you get what you pay for, so if you want it to last, there are a few things to keep in mind. First, be very careful placing the water tank into the unit as there is a standing plastic piece that can break off if the tank is not gently placed straight down. If this pin breaks, water will run out of the machine. Second, be sure that you have a good grip on the water tank when refilling as it is very heavy when full and if dropped or bumped into another hard surface, the plastic could crack. If the plastic cracks, then you lose the near-vacuum causing air to enter from the top once the tank is put back into the unit. If this occurs, the water will run out too fast causing a big spill.

Overall, though, this is a classy looking machine that is great for its price.

Sunpentown (SPT) SU-4010 Dual Mist Humidifier with ION Exchange Filter

Product Features:

Full List

The Sunpentown Dual-Mist Humidifier with ION Exchange Filter has a sleek design with easy to use control knobs and disperses cool or warm mist, depending on your preference of the moment. The 360-degree adjustable split nozzle offers a bi-directional mist for wider coverage. Perhaps the biggest selling point, though, is the ION exchange filter. It removes scale-forming calcium and magnesium from hard water by demineralizing the water, so you aren’t restricted to using only distilled or filtered water in your humidifier. This then prolongs the life of the generator and prevents white dust particles from depositing into the air.

A common complaint for this humidifier is that water leaks out of the tank. If this occurs, check the size of the washer (o-ring). If it is slightly too big, it will roll on itself when the cap is shut too tightly, so just unscrew the cap, check the washer placement, and screw back on. Also, remember that if you choose to switch from warm mist to cool mist, it will take time for the water to cool as the unit does not actively cool the water. So if you want to immediately switch from warm to cool with no cooling down period, then you will need to empty out the existing warm water and refill with cool or cold water. Otherwise, just wait for the unit to expel all the warm water from the base.

  • 1 gallon tank

  • Minimum 12 hour running time
  • Medicine cup
  • Quiet operation

Full List

The Vicks Pure Warm Mist Humidifier (with auto shut-off) boils water to a pure stream vapor that is up to 96% bacteria free which then goes to the cooling chamber where it mixes with dry air to finally release warm, moist air into the room. The attached medicine cup allows the use of respiratory medicines, inhalants, or essential oils to produce a medicated or aromatic vapor. There is no filter or parts that need to be replaced; just regular, weekly maintenance to be performed. Compared to most warm mist humidifiers, this one is fairly inexpensive. You get what you pay for, though, so this isn’t a machine that will last a lifetime, especially with regular, frequent use.
