    Types of Humidifiers

    Cool Mist Humidifiers

    Shop This Product

    Cool mist humidifiers function without a heating element and often use a wick in diffusing mist around your home. The fan is an important feature of this kind and serves to blow air through the filter.

    Due to the lack of a heating element, cool mist models are relatively energy-efficient. This lack of element also makes them safer to use around children.

    PROS:
    • Energy-efficient.
    • Reduce room temperature on hot days.
    • Includes filters to purify the air.
    • Safer for children.
    • Ideal during the summer.
    CONS:
    • Harder to clean and maintain.
    • Noisy at maximum capacity.

    Warm Mist Humidifiers

    The water in a warm mist humidifier is heated up almost to boiling point by a heating element. This heated water is then dispersed around as vapor, which can bring a snuggly and warm feeling around the home when it’s cold.

    Since warm mist models need to heat the water first, they use up more energy. Despite this, they’re reported to be a popular choice for many.

    PROS:
    • Don’t use fans, so are quieter.
    • Raises room temperature.
    • Less prone to mold.
    • Easy to maintain.
    • Well-suited to the winter.
    CONS:
    • Consume more electricity.
    • Risk to children due to heating elements.

    What to Consider Before Acquiring a Humidifier

    We know you’re keen to jump to the best whole house humidifiers that we’ve recommended. But, wait a few more moments and take into consideration the following factors before you buy!

    Environment

    Many whole house humidifiers operate by injecting mist — warm or cool — into the environment.

    For cold environments, a warm mist whole house humidifier serves the dual purpose of increasing humidity and temperature. In such environments, cool mist may be counterproductive and further reduce the temperature of the home.

    On the other hand, in warmer temperatures, a cool mist whole house humidifier will be an ideal choice. It’ll perform the dual functions of reducing the temperature and humidifying your home.

    Features

    Look out for these key features of whole-house humidifiers:

    Humidistat

    Environments should be kept at a healthy, constant moisture level. A humidistat is an essential feature that could impact on the health of your families. Maintaining optimal humidity will reduce the risk of suffering from heat strokes, dehydration, and fainting, in some cases (1).

    Water Tank Indicator

    This feature is key to knowing when your tank is drained or running low.

    Auto Shut-Off

    After procuring a humidifier, maintenance should be a priority. An in-built auto shut off mechanism is essential for this since it turns the unit off when water levels are low.

    Filter Indicator

    Many, but not all, humidifiers clean the air with in-built filters. These are handy but aren’t a staple. Filter indicators are ideal for an at-a-glance check if the filters are operating optimally.

    Warning

    A clogged filter can release pollutants back into the air and become a health risk, so ensure you clean out the filter regularly.

    Noise

    Fans are the major cause of the noise produced by humidifiers. This makes warm mist and ultrasonic humidifiers the quietest you’ll find. With these two types, the vapor doesn’t need to be ejected into the atmosphere by a fan, as is the case with cool mist humidifiers.

    On the high setting, the noise produced by the fans could be loud enough to disturb your sleep. This is a factor worth considering, especially in houses where there are babies or light sleepers.

    Capacity

    How disappointing would it be to find out that your humidifier is good enough for just one room when you have four rooms? Knowing the capacity is vital before making a purchase. Whole-house humidifiers should be able to service a few thousand square feet.

    It’s vital to ask about the mist output when trying to figure out the capacity of a humidifier. A higher output means that your spaces will be humidified faster.

    Water Tank Size

    This feature ties in perfectly with the capacity. Whole-house humidifiers cover a lot of ground. This directly impacts the amount of water they need to function. You wouldn’t want to refill your tank hourly or even daily.

    Humidifiers will consume more water when they’re running on their highest settings. The ability to go for longer periods before needing a refill is a great advantage. You should also consider one that has an easily detachable water tank.


    The Best Whole House Humidifiers of 2020

    We’ve extensively researched some of the most in-demand products on the market and have also taken into consideration what consumers’ reactions. The result? These seven best whole-house humidifiers.

    The backlash of very low humidity could be cracks on wooden furniture, carpet shock, and dry skin (2).

    This Honeywell model is built to get rid of dry air in the house. It’s equipped with a distribution tray, which allows the most efficient use of water in reducing heat and saves on energy consumption.

    Why We Love It

    Flow-Through Technology

    Flow-through technology ensures that water isn’t stagnant in a humidifier reservoir. This maintenance-related feature ensures that the unit will stay cleaner for a longer period. It’s reported that you won’t need to clean every 2-3 months, depending on your house settings.

    Control Ease

    We like how user-friendly this unit is and that the humidistat can be set for optimal humidity relative to outside humidity. Also, the user manual includes a recommendation table for reference while setting the thermostat.

    Easy Installation

    This model is installed directly onto the air handler or warm air supply of your forced air furnace. It’s a process that’s fairly easy to do. To complete the installation, you’ll need the installation kit and connecting components.

    Up to 4,200 Square-foot Reach

    The 4,200 square-foot coverage makes this model ideal for a big house. It’ll produce up to 18 gallons of moisture daily to keep your home adequately moist.

    Keep In Mind

    Installation Kit

    When purchasing this humidifier, keep in mind that you’ll have to procure the installation kit separately.

    Why We Love It

    This humidifier has an extensive reach and will serve spaces as large as 3,600 square feet, which is about the equivalent of a small house. Alternatively, if you don’t have this much space, you could go for the model with a 2,600 square-feet reach.

    Mist Evaporative Technology

    It employs cool mist evaporative technology to inject moisture into the surroundings, reducing the risk of static shocks. Moisture plays a vital role in rendering the flu virus powerless and slowing down the rate of transmission (3).

    Tank Refill and Maintenance

    The 3.6-gallon tank means that it serves for up to 36 hours before a refill is required. On top of this, the tank is moderately easy to fill, as you will just need to lay it flat in a sink while it fills up.

    It’s also quite easy to clean, with best practice being to clean every two weeks to avoid mold growth.

    Movement

    If ease of movement is important to you, this model should be a consideration. It comes with tiny caster wheels, removing the need for lifting it for transportation.

    Quick Tip

    If you need to take it upstairs, it’s advisable to empty the tank before lifting.
    Humidistat

    This model is equipped with an automatic digital humidistat that displays humidity levels. The humidistat also triggers an auto shut-off when the desired level is reached.

    This feature is a great energy-saver. The auto-shutdown feature is also triggered by low water levels in the tank.

    Keep In Mind

    Noise

    Since this is a cool mist humidifier, users report that the fan can be noisy at night. Consider adjusting the fan speed to keep the noise to minimal levels while the household is sleeping.

    This Aprilaire 700 does not have the coverage strength of the larger models. However, with an up to 4,200 square foot range, it still classifies as a high-capacity humidifier .

    This model is fan-powered and works together with the home’s cooling and heating system. It does this by the fan sucking in non-humidified air, humidifying it and circulating it via the vents to every room in the house.

    Why We Love It

    Up to 4,200 Square-Foot Reach

    This 4,200 square-foot capacity utilizes approximately 0.75 gallons of water every hour and a total of 18 gallons daily. This may not seem like a lot of water, but it’s enough water to humidify a big house.

    Great for Furniture and Electronic Devices

    This humidifier makes sure that the static electricity from dry air is in check by drawing in non-humidified air. This thereby gives the assurance of longevity to your wooden furniture, paintings, artwork and electronics.

    Automatic Digital Control

    Noise

    Keep In Mind

    Installation

    With this model needing to integrate into an HVAC system, users report the installation to be a bit tricky. Consider calling in an expert to help with this process and bear in mind that it will cost you, so factor that in if you have a budget.

    • Power button.
    • Steam icon.
    • Fill icon.
    • Drain icon.
    • Service icon.
    Dual-Sensor Automatic Mode & Humidistat

    We like that this model is built to function either manually or automatically, depending on user preference. However, it comes with an auto-mode that’s even more impressive.

    This mode allows it to monitor and automatically respond to humidity changes inside your home, depending on the outside temperature levels.

    Also, this mode will notify you when heat is being released or when water is being drained. It’ll also drain the water automatically after 168 hours, in preparation for canister replacement.

    Keep In Mind

    Warranty

    The Aprilaire 800 comes with a 5-year limited warranty. However, the initial installation must be done by an authorized technician, or else the warranty is void. Users report that the installation process is quite easy, and most people would rather prefer doing it themselves.

    The primary role of a humidifier is to control atmospheric humidity levels. This unit serves that purpose and a bit more.

    The pedestal-style humidifier can be a makeshift table, with an espresso color and a replaceable 12 x 12-inch tile top. It can match the design of your living space and serves the function of extra furniture.

    User-Friendly

    It’s quite straightforward to operate since there are only three buttons:

    • Power.
    • Target humidity.
    • Fan levels.
    Auto Humidistat

    This function takes the burden of determining the required humidity levels from you. The unit will adjust the inside humidity of the house relative to the outside humidity levels.

    Automatic Shutdown

    If you have concerns over energy use, then this feature may be the one to take note of. To make it easier to use, the burden of shutting down is handled by the unit itself. When the desired humidity level is reached, the shutdown mechanism is triggered.

    Keep In Mind

    Noise

    Users report that the noise from this fan is off-putting when running at high speeds.

    Why We Love It

    Convenient Refilling

    Refilling water is very easy with this humidifier. Since it’s filled from the top, all you need to do is pour water directly from above into the reservoir. There’s no tilting or turning to get a good filling angle, which is something users report with other models.

    It has a 6-gallon tank and an extended runtime of 70 hours, which allows for some spacing between refills.

    Presence of a Filter

    The Aircare 826000 comes equipped with a powerful Trapmax filter. This helps trap allergens and possesses antimicrobial properties for cleaner air.

    Wick Replacement

    We recommend that you change the wick at the start of every season. If you live in areas with hard water, you may need to make more frequent replacements.
    Coverage Area

    Consider this model as ideally suited for small houses. It’ll work efficiently to humidify spaces as large as 2,400 square feet.

    Keep In Mind

    All-Rounder Humidifiers

    Having a humidifier is a necessity for most homes, especially during the winter season. It improves the standard of living, and the benefits of owning one make the cost of acquisition worth every cent.

    The best whole house humidifiers take away the need to buy smaller room-size humidifiers. This allows you to control house humidity levels from a central location.

    Your final choice will be down to your personal preference, but it’s important to consider the age of the children living in the house before buying a humidifier. If you have small kids around, consider avoiding whole house humidifiers because of the risk of burns posed by their hot elements.
