The ideal indoor humidity level is somewhere between 30% and 50%, with most experts agreeing upon 45% as just right. Anything lower than that causes dry, itchy skin and eyes as well as irritated throats and respiratory tracts. Anything higher causes mold, mildew, and fungus to grow, exacerbating allergies and inviting infections. In extreme cases, it can lead to drowning. If possible, the best way to control moisture levels indoors is through humidifiers or dehumidifiers. One company that capitalizes on improving home air quality is Air Innovations with its large selection of humidifiers. What these have in common are the use of ultrasonic cool-mist technology, which makes for quieter units, permanent ceramic filters and antimicrobial protection.
The main differences between them are room size, tank capacity, run time, and appearance. For instance, the streamlined Air Innovations MH-408 is geared for medium sized rooms with its 1.1-gallon tank and 70-hour run time whereas the Air Innovations MH-512 is best for large rooms, with a 1.37-gallon tank and 80-hour run time, and comes in a variety of fun colors. The Air Innovations MH-602 is also for more spacious rooms, and it has a 1.6-gallon tank and an 80-hour run time as well. The MH-505 is ideal for bigger rooms too, comes with a 1.37-gallon tank, a 70-hour run time, and a trim, compact design.
The MH-505 possesses a rotating mist nozzle, a digital LED display, and a built-in Humidistat which monitors the humidity setting. There is a programmable timer that allows you to set the unit to turn on or off in 1- to 24-hour increments and an automatic shut-off for when the unit runs out of water. This humidifier comes with 4 levels of adjustable mist output ranging from Low to Supreme. As with their other humidifiers, the 505 is well rated and purportedly easy to use. The consensus appears to be that distilled water is preferable to tap water, and regular washing of the unit with vinegar is essential to prevent unpleasant powdery build-up.
I love this Air Innovations Humidifier! I by- passed the Showstopper for this unit and I am so happy with it! It is a smaller unit but just right for my needs.
This one seems a little lighter, but works great so far. It is very quiet, which we have to have. Happy so far!
I love this product! I fill it with water and set it to what I want the humidity to be in my room. It goes for 3-4 days with out needing to be refilled with water.
Warning: Do Not Use Hard Water! Wish I had known that before I purchased this great sounding product. This is not practical or cost effective for me, so I am returning it...
