Overview

Anyone who’s struggled through chilly days with cracked lips or burned through jars of lotion during colder months has experienced the effects of dry air. When the air in your home or apartment is too dry, it affects your skin and mucous membranes. This can dry out and irritate your skin, aggravate your sinuses and contribute to coughs and colds. Overly dry air also increases static electricity in your hair and clothes, and it makes cold rooms seem even chillier. Humidifiers reduce these negative effects by adding moisture to the air in your home.

There are several types of humidifiers. Central humidifiers are built into your air conditioning or heating unit, and they generally do a good job of maintaining healthy moisture levels in your air. However, older homes, apartments or homes in very cold, dry climates might need a boost of humidity from portable humidifiers.

Portable humidifiers use different methods to add moisture to cold, dry rooms. Evaporative humidifiers, like the Everlasting Comfort Ultrasonic Cool Humidifier, Black, are the most common type. They have a reservoir that dispenses water through a wicking filter into a basin, then a fan blows air through the moistened filter to dispense small water droplets throughout the air.

Ultrasonic humidifiers use ultrasonic vibrating diaphragms to force tiny drips of water into your air. They tend to be quieter than other humidifiers.

MORE: The Best Humidifier Filter

Both evaporative and ultrasonic humidifiers need to be cleaned regularly to prevent mold, minerals and bacteria from growing in the water basin. However, some higher-end ultrasonic humidifiers have built-in UV light filters that sanitize your water before it’s exposed to air.

Most modern portable humidifiers use evaporative or ultrasonic technology. Cool mist versions of these humidifiers are also becoming more popular. They emit room-temperature water droplets into the air instead of warm water, making them more suitable for year-round use than steam humidifiers.

After you’ve covered your humidifier basics, there are a few more considerations you’ll want to make before selecting the best unit for your home.
