If you tend to experience dry sore throats, watery eyes, and even a dry nasal passage from time to time in your home, chances are the air in your house is dry. This basically means the humidity level is very low and is a sign you need a humidifier in your home. While it's generally impossible for you to control the weather outside, you can certainly manipulate the relative humidity levels inside your home with a humidifier — and you can do so throughout your home by investing in a whole-house humidifier.

Whole-house humidifiers do exactly as their name suggests. They're responsible for altering your home's humidity level and are able to work hand-in-hand with your HVAC. When used properly, whole-house humidifiers have the potential to save you some money by not using too much energy on heat or even wasting energy on air conditioning. If you're thinking of purchasing a whole-house humidifier, you're in for a real treat, but the kink is knowing which one to buy. Fortunately for you, we've carefully made your search simpler by arranging a list of the best humidifiers out there for you to choose from.

How we selected products

With so many amazing brands producing quality whole-house humidifiers, it can get confusing knowing which product to take home with you. When buying a humidifier, you have to make sure the specs tally up with what you have going on at home. For this list, we considered the sizes of the humidifiers themselves. Some people value portability, for example, while others want a built-in option.

Another factor that went into consideration is the lengths to which the humidifiers can cover. Some are capable of reaching farther distances than others so there's no point for you to purchase a wide-range whole-house humidifier if you live in cramped quarters. Also crucial to note is the amount of water used by the humidifier. Some of the devices tend to be wasteful while others are more efficient, turning over optimal humidity with limited water resources.

We also looked at the ease of installation for those who prefer to do it themselves rather than call a professional. Finally, we considered the cost of the humidifiers and the reviews from verified buyers. There are also different types of humidifiers, such as ultrasonic, steam, and evaporative, and the one you choose depends on your living situation. Take a gander at the products listed below and make a careful choice based on which product you know will serve you best.
