Best Whole-House Humidifiers Reviewed – 2017 Buying Guide

​

With so many suppliers online and in stores, the task of finding the right humidifier for your house can become overwhelming. The first step is to know the reason why you are buying it; and finally, you can look into features and functions of humidifiers as you a trusted supplier.

Today, more and more people are becoming aware of the need for humidity in the home. Cold air holds less moisture, so, heating cold air produces dry air in the home. An excellent answer to the dry winter air problem is retrofitting a humidifier to your gas forced air furnace. After that, it’s just a matter of adjustment for comfort and overall benefit. This handy guide has therefore been put together to especially help you make the right decision when you finally decide to make this investment. Reviews will go on to cover humidifiers such as the Aprilaire® 600 Bypass, 24V with Digital Control and the Essick Air AIRCARE MA1201 Whole-House Console-Style Evaporative Humidifier among others.

Do I Need a Whole-House Humidifier?

Strange as it may sound, the right level of humidity will make your house feel warmer, which means lower heating bills. On the other hand, with low humidity comes an increase in allergies, dry lips, asthma, dry coughs, nosebleeds, dry skin, problems in the nasal passages and sinuses and, respiratory congestion. With a humidifier installed, all you have to do is turn it on and avoid all these complications.

Whole-house humidifiers are available in digital and manual models. Digital models tend to be highly automated, and they are the most preferred options. With these new technologies, you only have to select and input the amount of humidity you want, and the unit’s built-in humidistat monitors your home’s air for moisture, keeping it at the desired level. For manual models, however, everything is done manually, in that you have to adjust your humidifier yourself every time there is a need to.

Your furnace blower system can also run the whole-house humidifier, which is a bonus because only seasonal maintenance is required. Unless you are doing an individual room, this is the best option. Finally, portable units are available but require more maintenance.

​

How a Central Humidifier Works

These attach to your furnace and are fed with a water pipe attached to the household plumbing. Some models inject a mist into the ductwork; others use a foam cylinder which rotates in a tray with air blowing over it. Because it is fed from the house water supply, you can keep your whole house at the desired level of humidity without worrying about filling tanks or having them run dry. This type of humidifiers operate virtually silently, cost almost nothing to run and are cheaper than a portable unit. Units are available for radiant or baseboard heat systems.

You can have your humidifier professionally installed, or you can do it yourself. Depending on where you live, the water may cause an accumulation of minerals; this will need to be cleaned out with vinegar once a year. It is best done immediately at the end of the season before the deposits have time to harden. This is only a problem for water supplies with hard water. There are several easy tests to see if your water is hard that can be found online.

Portable Humidifiers

The portable unit is suitable for a student dorm room or a renter. As the name implies, these units can be moved from one room to another, usually on casters. They have their own reservoir which you will need to keep topped up, and they require about 120-volt power outlet to plug into. Sizes range from small table top units, suitable for a small room, to the more powerful units which will cover several rooms at a time.

Because it is self-contained, a decent portable humidifier will cost you more than a whole-house humidifier. The household furnace’s blower powers the airflow in a whole-house unit while a portable unit must have its own. Portable units can be heavy, require more maintenance, and can be noisier than their whole house counterparts. They also have a water reservoir, either a removable tank or one built in, which needs to be kept topped up and clean. Bacteria, fungus, mildew and mold all thrive in stagnant water, and they will end up in your air if you don’t take proper care. This is a particularly important for people with conditions such as asthma and allergy.

​

Choosing your Whole-House Central Humidifier

The type of humidifier you choose will depend on your particular objectives and most importantly, your budget. It will also depend on whether you want a central, entire house or whole house system.

A central humidifier is attached between the hot air duct and cold air return of your forced air furnace for heat, humidification, and air conditioning to enter the house. Hot air is redirected through the humidifier, and being hot, it will hold moisture. This air is forced into the rooms as water droplets evaporated into the air in all rooms through the air vents. Ideally, each room should have an air return. Sometimes, based on square footage and furnace power output, HVAC technicians will create a large air return for new furnace installations to accommodate the need.

Warm air from the forced air furnace is used by these units to distribute moisture into the air in the home. Warm air from the heating ductwork is directed through a water panel, also known as a filter that distributes moisture vapor through the entire house. These units can be installed on a forced air system on the supply or return air plenum, where the air is pressurized for circulation.

All in all, basic humidifier types include Steam, Bypass, and Fan.

Bypass Humidifiers

Drainless bypass humidifiers are available where there is no floor drain, these recirculate their own water, thereby saving on water usage, and on plumbing to remove the condensation. The bypass is mid-range with regards to functioning and cost. Aprilaire® Bypass Humidifiers make a good example of a bypass humidifier.

Fan-Powered Evaporative Humidifiers

These are also known as evaporative cool mist humidifiers. They are similar in their workings to bypass units with the exception that they use a fan to blow air over the water panel to assist evaporation. The advantage is about a gallon or more of extra moisture produced per day. Bypass ductwork is not used so smaller areas are needed for installation which is ideal for homes built with a furnace installed in a closet room or a home built on a slab. The Honeywell® HE300A1005 TrueEASE™ and Aprilaire Model 700 are good examples of this.

Steam Humidifiers

These put moisture into the air by heating water until it becomes steam. They are sometimes known as mist humidifiers. The furnace’s blower sends the moisture laden air through the house’s ductwork and into the rooms. This method is fast and efficient, provides moisture as needed, but it is also the most expensive. If you are considering a steam humidifier, the Aprilaire® 800 Automatic Whole-House Steam Humidifier is a good choice for certain house sizes. It works independently of the HVAC system in larger homes.

What to Look for In a Whole-Home Humidifier

The simple process of adding moisture to the air in your house, known as humidification is among the most important factors to be considered for all round indoor comfort. Here are some five things you should look out for:

Coverage

As the name implies, a whole-house humidifier is manufactured to cover an entire house, however, it is necessary to check actual coverage. Coverage of units can range from 4000-square feet to 2500-square feet. Some humidifiers are built specifically for a baby or toddler’s room.

Evaporation Rate

Higher evaporation rates mean more air will be saturated with moisture in a given time.

Control Mechanism

When it comes to humidifiers, automatic and manual control features are available. This is therefore largely a matter of personal preference and budget. However, an automatic humidifier comes with an Automatic Humidistat which calculates the humidity and adjusts moisture output accordingly.

Installation

For humidifiers, installation can be a tricky affair. A licensed HVAC professional may be required to install units that interface with a gas forced air heat furnaces. Also, some manufacturers void their warranty if the installation is not done by a licensed HVAC professional.

Maintenance

You can avoid unnecessary expenses by checking the maintenance requirements prior to making your purchase. Modern humidifiers are so advanced that minimal cleaning is required, along with filter changes.

​

Benefits of a Furnace Humidifier

If you live in a cold region or your region experiences a dry climate all year round, putting a bit of extra humidity into your living environment will be of great benefit. Almost everyone knows about the small, portable vaporizers and humidifiers used for babies’ rooms. You fill the tank, and when the water runs out, you top it up or switch it off. Moreover, the unit can be moved from room to room.

Not so many people, on the other hand, know about the operation or the benefits of a whole-house humidifier. These units are installed into your heating and cooling system. Water vapor is then injected at the heating ducts, and the temperature is controlled by your thermostat while humidity levels are controlled by a humidistat. You can adjust the level of humidity according to your needs. A water line is also attached to the plumbing of the house, which is a fairly simple process.

The advantages of whole house units include:

  • They require low maintenance since you only have to just occasionally check the filter
  • It is easy to achieve whole-house humidity. For digital humidifiers, you just set and forget.
  • No water tanks to fill required
  • No need to purchase a blower because a humidifier uses the one in the furnace
  • Health benefits associated with humidity include moistened skin and lips, no chapping, no stuffed up or congested nasal passages and sinuses, less allergies, and best of all, plants love it
  • Humidity comes with its benefits such as extension of the life of wooden floors, furniture, papers and artwork. You must however ensure that it is not too high as it will also cause mold to grow. Ideally, you should keep it between thirty and fifty percent
  • Not only is humidity good for you, it also guards timber flooring, furniture, plaster, electronic components and musical instruments against cracking, warping and deteriorating. Humidity also protects wallpaper from cracking and peeling

​

Please note that you can’t put essential oil into humidifiers, but if you want a relaxing and aromatic environment, Essential Oil Diffusers are available.

Finally, here are twelve of the best whole house humidifiers for your consideration. Check them out to ensure you make an informed decision on exactly what you need for your home.

Tips for getting the most out of your home humidifier system

As you get started using your humidifier, there are some special tips to observe.

1. Do not put essential oils into your humidifier! Even if the manual doesn’t specifically say you can’t, YOU CAN’T. The oil will mess up the inner workings.

2. Boiling hard water does not get rid of hardness. The minerals in hard water will adhere to the inside of the unit. Using distilled water is best.

3. Every degree you turn down your thermostat saves you up to 3% on your energy bill.

Final Thoughts

Hopefully, some of the mystery has been taken out of humidifiers, and you are now armed with enough information to make an informed decision.

Follow the installation and electrical requirements; take proper care and do proper maintenance as required. That way, your humidifier will give you many years of comfort. Enjoy!
