What Is a Whole House Humidifier? When Would I Need One? 

There are two basic types of a whole house humidifier that can be purchased today. The first, which is a console humidifier, sits within your home and acts like a traditional humidifier would. It takes water from a tank, processes it into water vapor, and then expels it into your indoor environment to improve humidity levels. Tanks for a console humidifier can be 14+ gallons in size, allowing indoor air modification to occur in spaces that reach 4,000 square feet in size.

A console humidifier is a solid choice for homes that have an  open floor plan. They’re also suited to improve humidity levels in office buildings and other commercial or light industrial locations. If you don’t have an open floor plan, however, the benefits of a console humidifier can be quite limited. That’s when you’ll want to consider the second design option.

Some whole house humidifiers can be hooked directly into your current HVAC system. These central evaporative humidifiers attach to your furnace or other heating equipment, tap into your plumbing system, and provide humidified air to your entire home You may need to have this type of humidifier professionally installed, however, which may add $100-$250 to the product price.

These humidifiers solve one common problem: a systemic lack of humidity. Not every home has this issue, so measuring humidity percentages over a period of time can help you determine if the purchase of a whole home humidifier is right for you.

The Advantages of Owning a Whole House Humidifier

The primary advantage of owning a whole house humidifier is that you have an easy way to maintain humidity levels. Some can be programmed right at your wall thermostat, while others have a built-in humidistat to use. Many can be plumbed directly into your home’s water supply, so you never have to worry about a tank running dry. In return, you receive an accurate humidity level that is easy to maintain and for the HVAC options, may even give your home some added value.

There’s also the consistency advantage that a whole house humidifier can provide. Unlike the smaller room-sized options, you receive consistent humidification throughout the entire structure, preventing damage to your structure while lowering your own risks of health consequences that come about when humidity levels are too low or too high.

For the central evaporative humidifier, there’s also the advantage of the humidifier being out of sight from the primary living space. Console humidifiers take up space, but are designed to look like part of your interior design. Some even allow for the top surface to be used as shelf space for decorative purposes.

The Disadvantages of Owning a Whole House Humidifier 

The primary disadvantage of owning a whole house humidifier is based on how it must be installed. Some manufacturers of humidifiers in this category will require you to schedule a professional installation for them to honor the warranty that is associated with your preferred model. You’ll want to check each whole house humidifier review to determine if this is the case for your preferred model.

Because of the scope of humidification these models provide, you may also find that you need to clean your humidifier frequently to maintain the unit. This is particularly true if your unit is plumbed into your home and you have a hard water supply. Some homes may even need to install a water softener to make sure their humidifier is able to work as it should.

There is also the potential for mold and mildew growth within these systems because there is always water available. This is especially true within console humidifiers with their large reserve tanks. You may need to run bleach, vinegar, or other disinfectants through the humidifier on a regular basis, which reduces the number of days you can have it operating to provide humidification.

What Are the Prices of a Whole House Humidifier?

 From a product cost standpoint, the humidifiers that tap directly into your existing HVAC system tend to be a little cheaper than the console humidifiers that can improve humidification for the entire home. Central evaporative humidifiers that hook into your furnace are typically priced in the $100-$250 range, whereas console humidifiers tend to be priced in the $250-$400 range.

The difference is that you will typically not need to have a professional installation scheduled with a console humidifier. Although they are large and somewhat heavy, you can take a curbside delivery and get it placed into the perfect location at your home. You may need to have a professional installation with the central evaporative humidifier, which adds another $100-$250 to the price, making the costs very similar between these two styles of whole house humidification.

Vornado Evap40

This is the perfect humidifier for smaller homes. Using vortex circulation to improve humidity levels, it works best when the space is 1,000 square feet in size or less.

The water tanks are easy to fill on the side of this model, though you’ll need to do this once a day under heavy operating conditions. One word of caution: this model does require two filters, so there is an increased level of maintenance with this humidifier compared to some other models.
