Thermostatic control modifies internal climate to accommodate for comfort or necessity. Heating and A/C make harsh conditions more habitable but they can dry out the air in the process. Too much moisture leads to mold or mildew and too little wreaks havoc on the sinuses and skin. Dehumidifiers exist to ameliorate the first problem and humidifiers are effective for the latter. Many humidifiers are of the ultrasonic variety. These use a ceramic diaphragm vibrating at ultrasonic frequencies to create a cool mist which is then forced out by a fan.
A few examples include the PureGuardian H7550, an elegant device that dispenses either cool or warm air for up to 90 hours. The Air Innovations MH-801B might look like a giant snail but it has a 120-hour run time. The Apalus HF001BK is another ultrasonic, point-of-use humidifier that can be remotely controlled. It has a 1-gal. tank which enables it to run for 24 hours on a single filling. Once the humidity rate is set, the HF001BK has an automatic moisture balance system which will maintain a constant relative humidity level of 40% to 90%. When the water gets low, this device will automatically shut itself off. It also possesses something called a "purify air ionizer" which purportedly spreads robust, healthy negative ions in order to reduce bacteria, viruses, mold, and fungus.
There are 3 settings available to control the amount of mist, and two 360-degree rotating outlets for disbursing it. The night light is touted by Apalus as perfect for the bedroom, although it seems to be the biggest issue for those who can't sleep as a result of its insistent luminosity. The remote control uses a CR2025 lithium battery and can be utilized from up to 15 feet away. The LCD display allows for manual control while showing operational status. This appliance is best suited for rooms up to 300-square feet, and it includes a replacement demineralization cartridge. Since the downside of these humidifiers is that the water droplets will possess whatever impurities are in the reservoir, it's important to clean them out with vinegar on a regular basis.
A life saver for my desert dry air! I've owned several brands of humidifier over many years and this one is by far the best money ever spent.
I like the product with constant humidity function, it is easy to use with a remote control as well. Works great and very efficient customer service!
