Air-O-Swiss AOS 7147 UltrasonicAir-O-Swiss AOS 7147 Ultrasonic

This dual system can switch between cool and warm mist. Heavy duty with a capacity of humidifying 600 square feet of area, a built in timer for setting between 1- 8 hours, this is the smartest of its class. Control the humidity level so it does not drastically change while you sleep.

This is due to its ITC, or Intelligent Temperature Compensation technology. Hydro cells keep the ambience fresh and its ITC helps keep the climate perfect.

 The reason Air-O-Swiss AOS is great for large rooms is because of its output capacity. With a relatively high capacity, it has an output of 3 gallons per 24 hours. It does have a large tank capacity, as it can take in 1.5 gallons at a time. That in mind because of the 3 gallons per day output, you'll have to refill it about twice a day if you have it running full steam, 24/7 but that's pretty normal if you want to fill up a large room.

Buying Guide & What To Look For

Cool mist humidifiers aren't cheap, and if you're looking to buy one you'll want to make sure you do the appropriate amount of research. here, we'll let you know what to look for before you make your decision. First, it's important to understand that cool mist humidifiers are either ultrasonic or evaporative.

Purpose - Allergies vs Dry Skin vs Sleeping vs Protecting Wooden Furniture

There a lot of reasons to get a humidifier - with most people deciding to get one for health or their furniture. There are a lot of health benefits to properly maintaining the humidity in a room.

Moisturizing Dry Skin

The most obvious benefit is that more moisture in the air will help keep your skin moist. Dry air can cause dry skin and rather than slathering on a ton of moisturizer using a humidifier is more convenient, less greasy, and can be more affordable in the long run.

Fighting Allergies

Similarly, in denser, more humid air there are fewer pollutants in the air and they can help allergies, especially if you feel them while you're inside the home. More water particles will cause other particles to rise due to the density of the water particles and there will be fewer particles to be allergic to overall since adding additional water particles reduces the overall density of allergens.

Sleeping

Many people are not aware, but a big reason people have trouble sleeping is because of the ambient air. Dry air can cause dry throat and eyes, hurting the ability to get a good night's sleep. Having a better-controlled environment will allow you to get more consistent sleep. You'll not only get less sore throats but will also achieve deep sleep more easily.

Protecting Your Furniture

If the air is too dry it can actually damage your wooden furniture. If the air is too dry it can suck the moisture out of the wood, ruining the balance between water and oils that are healthy for your wood. In extreme cases, this can cause wood to warp or crack, potentially damaging your furniture in significant ways. If you have expensive furniture then you'll definitely want to invest in a humidifier.

Ultrasonic

Ultrasonic humidifiers vibrate the water out to send water vapor into the air. It accomplishes this by using high-frequency sound vibrations. Despite what you may think, ultrasonic machines are usually quieter than evaporative.

However, ultrasonics don't have a filter so if your water is very hard ( has lots of minerals) you'll get a lot of mineral deposits dust in the rooms. I live in California where the water has a lot of mineral deposits so I decided not to go with this option as it also made cleaning more difficult because of the dust. The dust is subtle so you won't typically see it, but it does build up after a few days in which case you'll want to wipe off the surface of everything in the room.

Evaporative

Evaporative humidifiers evaporate the water that is inside the machine then distribute the water vapor out, increasing the humidity of the ambient air. This is the most common of the two and is similar to what people have done for centuries - taking a hot pot of water to allow it to steam up the room and increase the humidity and make the air less dry. Unlike ultrasonic options, evaporative choices have filters that will filter out minerals, preventing the mineral dust build-up.

While this is good, that means you need to replace and buy additional filters and that you'll need to clean them. They're a lot easier to clean than a whole room though so we opted for this type.

They are generally the cheaper of the two options.

Location - Bedroom, Kitchen, and evaluating Portability

Where do you want your humidifier? Having it in the kitchen compared to your bedroom requires different considerations. For example, in your kitchen you are in a lot, may have guests, and have lots of equipment that you'll be using to prepare foods you eat in which case you'll want to avoid mineral dust and you would want to more closely consider evaporative.

In a bedroom, on the other hand, you have a little more flexibility and it comes down to preference.  Both types of humidifiers will work and it just comes down to preference in what we mentioned - keep in mind if it's in the bedroom you'll actually be in the room for at least 8-9 hours (as it's where you sleep) so you'll probably want a higher quality machine since.

Of course, you can get a portable option if you want to move your cool mist humidifier around. It's not ideal, but if you're on a budget then a portable one may be the best option, but it sacrifices convenience since you'll have to lug it around the house whereas if you had multiple then they'd already be in the appropriate rooms.

Large room vs Small Room

If you are looking to humidify a small room then almost any of these options will do well for you. However, if you need one for a large room then you'll want a humidifier with good output and tank capacity. The output tells you how much it can increase the humidity of a room by, while tank capacity is how much water it takes in. If the output is high but the tank capacity is low then you'll find yourself annoyed with how much you'll have to refill the tank. For example, if the output is 3 gallons a day but the tank capacity is only .5 gallons, that means you'll have to fill up the tank (3/.5 = 6)  6 times a day, which is a LOT!

For large rooms, go with our recommended option of the Air-O-Swiss AOS 7147  - it has an output of 3 gallons per day and an input of 1.5 gallons. With great output, it'll work for large rooms while only requiring 2 refills per day.
