Whole-House Humidifiers help keep you healthy by preventing dry air. As “The Authority on All Things Real Estate,” you bet we’ve made a list of your best options this winter. Read on to see our favorites from around the web.

Why Use a Whole-House Humidifier?

Every winter brings colder temps and drier air. We’ve all experienced cracked lips and rough skin that occurs from the lack of humidity in cooler months.

Or maybe you’re tired of battling static hair á la Cruella de Vil. A quick fix is to put a few small humidifiers in your bedroom and other common areas. Still, you’ll need to do the legwork to refill the water frequently.

A more powerful option is to install a whole-house humidifier. Whole-house humidifiers attach to your ductwork and blow moist air into your home.

This can improve the quality of life for all members of your family and is particularly important for young children.

Best Overall: Honeywell By-Pass Flow-Through Humidifier with Water Savings

This sophisticated tool costs just $218 at Home Depot. The Honeywell humidifier works with your home’s heating and cooling system to create a comfortable humidity level throughout the house.

It’s a great option if you are concerned about increasing energy costs, as the technology is designed to use 30% less water than standard models.

The result is a more comfortable home with added benefits of preventing woodwork and furniture from drying and cracking. Because it works with your existing HVAC system, the effectiveness of this humidifier depends on how efficient your home’s systems are.

It works best for newer homes (less than 20 years old) for up to 4,000 square feet. If your home is more than 20 years old, it works for up to 2,000 square feet.

Mount the humidifier on either warm air supply or return air duct of forced-air furnaces. The result saves money for a comfortable home and is a lot less maintenance than smaller humidifiers.

Reviewers say their home felt more comfortable in just a few days. DIY installation is possible, but take your time and remember the old adage: Measure twice, cut once. Homeowners say installation is easy but time-consuming. You can expect to take a few hours to get the unit in place.

Best for Homes Without HVAC Duct System: Aprilaire 865 Whole House Steam Humidifier

If you live in a home without a traditional HVAC duct system, this high-output steam humidifier is the answer. It’s an investment for $908 on Amazon, but reviewers say it’s worth the price.

A wall-mount fan pushing humidified air into the living space without an HVAC duct system. It also has impressive full coverage for up to 6,2000 square feet in tightly built homes.

The design uses electrode technology. It has six output levels that can add up to 34.6 gallons of moisture into the air each day. There’s a dual sensor and 24/7 auto mode that continually responds to outdoor temperature and indoor relative humidity.

Just set it and forget it. For those suffering from allergies and asthma, it’s worth every penny. It has been shown to reduce the incidence of respiratory infections.

Reviewers say installation is easy. It only requires a simple water supply connection and the addition of a 240v circuit. If you aren’t particularly handy, enlist the help of a handyman.

Buyers were also happy with the results for added comfort in the winter. Most simply switch the system off each summer.

Best Value: Aprilaire 500M Whole House Humidifier

The manual humidifier has a single sensor built into the standard control to monitor indoor relative humidity. This is for use in manually setting the percent humidity in your home.

It doesn’t have the fancy bells and whistles of its $900 counterpart, but this option is great for smaller homes. The only extra step is setting the percentage of humidity on your own — it won’t adapt to outdoor temperature like the higher-tech options.

Reviewers were delighted with the results. If you aren’t familiar with basic wiring principles, enlist the help of a handyman. If you do have some basic skills, installers say it can be DIY’d in several hours.

The classic white design is on casters for easy mobility. It has a digital humidistat to maintain your home’s humidity automatically. It is powerful enough for a whole house up to 3,600 square feet.

Once installed, reviewers said the unit was quiet and efficient. If you need to cut a hole in your duct, it may be best to enlist the help of a professional or rent a Dremel with cutoff a wheel.
