'Tis the season for rocking around the Christmas tree -- and turning up the heat. If you live in an area with frigid, cool weather this time of year, you're likely cranking up your heat to stay cozy. And if you already live in a dry climate, you're all too familiar with what this may mean -- dry air. Air that lacks sufficient moisture can cause discomfort and easily irritate your hair, skin, throat, nose, and more.

With tons of humidifier options on the market, it isn't easy to sort the best ones. The perfect fit for you is a humidifier that fits your physical space and your wants and needs for a product.
We chose these humidifiers through a mix of research and personal experience. We also took the following into consideration when making our top picks.
The ideal humidity in a home is to some level dependent upon personal preference, though the Centers for Disease Control and Prevention (CDC) recommends keeping the humidity levels in your home "as low as you can" and "no higher than 50% all day long."
Most professionals online suggest keeping your home's humidity somewhere between 30-50%, though some outlets say up to 60% is fine. Just keep in mind that an increase in water vapor in your home increases the chances of mold and mildew growth, and that humidity rates fluctuate throughout the day and throughout the seasons. The CDC additionally suggests maintaining proper ventilation within your home, especially in areas such as kitchens or bathrooms.
The ideal tank capacity for the humidifier that best fits your needs is going to depend on the size of the room you are looking to house your humidifier in and how often you plan on running your device. If you're only wanting to up your room humidity when you sleep, you won't need as large of a water tank as you would if you're planning to run your humidifier all day.
It's key to keep in mind your portability needs, too. Do you need to move this humidifier around a lot? Will it remain in one room and one spot? If you want a humidifier with better portability, a smaller tank size may be best so you aren't lugging a larger device with a copious amount of water back and forth.
Generally, you can choose your humidifier based on three different room sizes: small, medium, and large. Here's a ballpark room size to tank capacity to use as a basic guideline.
As you're looking for your humidifier, you'll see that most brands give an idea of the room size the device is appropriate for, or the number of gallons the tank holds.
Portable tabletop or room humidifiers are not your only option to add moisture into your home. If you live in a climate that is dry all year round, or are particularly sensitive to low humidity and prone to dryness, you may want to consider a whole home humidifier.
Whole home humidifiers can be installed either inside your home's HVAC system, or mounted on the outside. They are traditionally connected to a house's electricity and plumbing though specific installation methods can vary in complexity and differ by humidifier types, brands and models. While a whole home option may be the best option, keep in mind that some drawbacks include installation requirements, maintenance and upkeep expenses on a much larger scale, and the potential for mold and mildew growth.
Humidifiers are often used to soothe and relieve common effects of dry indoor air: soar throats, nosebleeds, chapped lips, dry and itchy skin, and more. Primarily during colder weather, an increase in heat use and the changes in the weather can generate less moisture in home environments, leading to uncomfortable conditions.
Humidity acts as a moisturizing agent that soothes seasonal affiliated dryness in children and adults, but it can also be used to provide extra water vapor to plants, babies, and more for similar reasons year-round. Humidifiers require regular upkeep and maintenance to remain healthy and clean for users.
Evaporative humidifiers build upon the simple concept of naturally letting moisture evaporate into the environment to relieve dryness. These types of humidifiers speed up this process by using a fan that blows air through a moistened wick filter. In turn, as the water evaporates, it is expelled from the humidifier as water vapor.
On the other hand, ultrasonic humidifiers use two ceramic plates that vibrate at a high frequency to create humidity. The plate vibrations produce a fine mist that spreads into the air, where it evaporates, thus producing humidity. Ultrasonic humidifiers require purified or distilled water and can be more upkeep.
Both types of humidifiers can generate water vapor in your space, but you may find that one option is better for you than the other, depending on your wants and needs.
While ZDNET rounded up the best humidifiers according to research and personal experience from our experts, there are tons of other options available across retailers that may fit your needs. Here's a few other humidifier options to consider for adding the perfect amount of water vapor to your space.
If you're not looking to sacrifice your aesthetic, the Vitruvi Cloud humidifier offers a sleek, minimalist design and 24 hours of quiet, humidity-building technology for up to 600 square feet.
This evaporative style humidifier offers up to 400 square feet of floor coverage and is available in larger models, too. It also utilizes plain tap water to function, and is easy to clean.
The PureBaby humidifier from Pure Enrichment packs fun, child-like design in the shape of a cloud with up to 24 hours of ultrasonic misting for up to 250 square feet. A built in color-changing nightlight equips the functions, too.
Hvac Scenting The Everlasting Comfort humidifier provides up to 500 square feet with 50 hours of misting time, and is accompanied by a massive 6L water tank.
