Description

Breathe easier with the Air Innovations Ultrasonic Cool Mist Digital Smart Humidifier - Model 505A. For its size, it runs longer and it’s more versatile than any other humidifier on the market. This fully featured unit has a 1.37 gallon tank the runs up to 70 hours on low – that’s almost 9 nights of sleep before you have to refill it. The operation of this humidifier is silent for a peaceful night of sleep, yet it’s powerful enough to add humidity to large rooms up to 400 sq. ft. Other features include: built-in programmable humidistat that monitors and maintains the humidity levels that you set, a permanent ceramic filter that traps impurities from water, and a 360 degree rotating mist nozzle helps direct the moisture where you want it. It also features a fully programmable timer that turns on and off when you want it to, top and bottom handles for easy filling and carrying, extra wide opening for easy filling, and an auto out-of-water shut off when it runs out of water. It will also help kids and babies because the extra humidity will relieve dry eyes, rehydrate skin, help scratchy throats and will help reduce snoring for better sleeping. It also protects and rehydrates furniture, wood cabinets & floors and acoustic & electric guitars.

    • Perfect for our use
Color: Blue
Disclaimer - I have only used this for one night, but seems to work well so far. We were using an Optimus U-32000 "warm mist" type for many years, which I absolutely loved since it had a humidistat and did not have the "white dust" problem of ultrasonic types. The only problem with the warm mist humidifier was that the humid hot air rose up to our old plaster ceiling, condensed on it, and after 10 years caused the plaster to buckle. So we put this MH-505 humidifier 4 feet from the bed, with the vent pointing towards it. Hopefully the cool moist air will stay low and not effect the ceiling. I set the power on "low" and the humidistat on 40% (the lowest it will go) and placed a separate humidity meter next to the bed. The separate humidity meter read 20% before we turned on the humidifier, and by morning had risen to 30% which is exactly what we wanted. It only used 1" of distilled water overnight (on "low"). Pros: I love the features and the display, and the ease of setting it. The "dim LED" feature is a great idea - it shuts off the bright LED display so it does not keep you awake. I like the shape, color, and design. The only "cons" I have is that I wish you could set the humidistat down to 30%RH (it currently only goes to 40%), and I wish that it could display the surrounding humidity down to 10% (it currently only displays down to 31%). ... show more

    • Very nice humidifier
Color: Blue
Well constructed and performs great. Raised the RH of an 18' X 11' room to a comfortable level in about 40 min on highest setting. What I really liked was the fact that this machine produces a very fine mist; there was no pooling or accumulation of water on the surface where the unit sits. It is super quiet....only an occasional "gurgle". Used the unit at night in a bedroom. Some reviewers found the LED display not too bright for bedroom use, however for me I preferred to use the dimmer switch as there is are a lot of LED's lit up on the display. The display can be minimized / dimmed. Distilled water is suggested for hard water systems, however the instructions mention filtered water can also be used. I am using water from my BRITA filter system. Will see if this is sufficient to prevent any buildup. Water tank is large and seems to be sufficient for extended use without refill, even at high settings. ... show more

    • Perfect for a small or medium sized bedroom and looks cool
Color: Blue
I needed a steamer for my son's bedroom when he had bronchitis. I've previously used Crane, but I needed a new one. It works great and puts out a lot of steam for a small unit. We use it on the lowest setting in my son's room, which is about 130 sq. ft, with 8 foot ceilings. It puts out a decent amount of steam. I also used it in a larger space on a higher setting with good success. It helps him sleep better at night. It is relatively easy to clean, as far as these types of devices are. There is a 'ceramic' filter inside which needs to be rinsed periodically. I'm not sure exactly what it's supposed to do, probably reduce mineral content. The one feature I like is the ability to dim the display at night. I haven't used any of the other fancy features, so your mileage may vary in that respect. The design is cool and reminds me a bit of a Transformer. It has a very small footprint, so it can fit on a dresser or sturdy shelf. Overall highly recommended. ... show more

    • Oh So Silent wonderful Humidifier
Very attractive, yet unobtrusive, Humidifier. Runs quietly, all night, in my bedroom. Be sure to use the "Dim Light" setting for the dial, if you are sensitive to light. Liked the first one so much, I ordered a second for my home office.

    • Powerful but eats water on higher setting
Color: Blue
This will drink gallons of water depending on setting. Its quiet and works well but if you are buying distilled water you will be spending a fortune. Also its hard to clean, gets slimy and there is no real good way to clean it out. I can see the slime inside the tank but cant figure out how to clean it, Used hot water, vinegar, rubbing alcohol and water shake shake shake and still slimy. ... show more

    • Beats the NYT's Favorite Levoit
This is the second of this model and the third Air Innovations humidifier I have purchased. The New York Times WireCutter's favorite by Levoit comes up far short. The Levoit requires a network connection and an app just to set the humidity levels. It only comes with a cheap foam filter. And top filling is no easier than filling the Air Innovations. The AI's more effective filter can manage hard water. It has a wider level of mist settings. And setting humidity levels is easy. There is no function that can't be controlled via the front panel. There is absolutely no network connection required. It has hand grips on both the top and bottom for easy transport empty or full. It is a much more substantial unit. For another $10-15, the WireCutter shouldn't even be considered. Oh, and it comes with a filter brush attached to the inside of the base - very intelligent product design. ... show more

    • Malfunctions
Color: Blue
I’ve had this humidifier less then two years. It is used only at night. I like all of the controls. My routine is to turn it on, set the humidistat to 45 (sweet spot for sleeping), set the timer for 9 hours and then dim the display. Done and done. It shuts off in the morning before I go to work. When I turned it on last night, the display went immediately to “preset”, then toggled itself to timer screen and cycles through the timer numbers endlessly. It doesn’t turn on and I can’t get it off that screen. I tried unplugging it and that didn’t help. It wouldn’t turn on at all after that. If that hadn’t malfunctioned the only complaint I have is the base is awkward to descale and clean. I live in a dry state with hard water so descaling with white vinegar is necessary. The tiny brush they provide doesn’t help much. It’s just a tedious process due to all the nooks and crevices. I have contacted the company regarding the display malfunction but recent reviews have stated minimal responses :( ... show more
