If you’re waking up with a dry mouth, sore throat, difficulty breathing through your nose, or even nosebleeds, it might be due to dry air. You might want to think about using a humidifier. Living in Kansas, right in the middle of
nowhere the U.S., I’ve found the indoor humidity to be around 30% in the summer and only 20% in the winter. My daughter frequently gets nosebleeds, and the doctor said it’s because of the overly dry air and suggested using a humidifier.

What should the indoor humidity level be?
If the indoor humidity drops below 30%, it can get pretty uncomfortable. Dry air can lead to itchy skin, exacerbated sinus issues, dry eyes, and so on. A range between 30-40% is generally comfortable for most folks. However, if the indoor humidity exceeds 50%, you’re risking mold growth.
When your space gets too dry (like when you’re cranking up the heat in winter), increasing the humidity can:
- Help with dry, painful noses and even prevent nosebleeds.
- Keep nasal passages moist, which can alleviate symptoms of colds, allergies, and asthma.
- Reduce pesky snoring.
- Soothe dry, itchy, cracked skin and lips.
- Cut down on static electricity.
- Protect your precious wooden furniture, flooring, and musical instruments from cracking and warping.
- Moist air can help retain heat in the home, potentially lowering heating costs.
Types of Humidifiers
The simplest way to humidify a room? A bowl of water. But if you’ve got carpet, that’s not ideal. Common market options include Ultrasonic Warm/Cool Mist, Evaporative Warm/Cool Mist, Whole-House Humidifiers, and Air Washers. The first two typically range from $40-100, while the latter two start at $140 and up.
Ultrasonic Warm/Cool Mist Humidifiers
These humidifiers often have “Ultrasonic” or “Warm/Cool Mist” in their names. They use a metal diaphragm vibrating at an ultrasonic frequency to nebulize water. The fan at the bottom then blows this mist into the room, increasing the humidity. Cool mist versions release mist slightly cooler than room temperature. The warm mist option heats the water to about 176°F, then nebulizes it. When this mist enters the room, it cools down to about 104°F, giving a warm mist effect.
- Lots of stylish designs.
- Compact size.
- Requires pure or distilled water.
- In areas with hard water, using tap water can lead to scale build-up and potential damage.
- The mist doesn’t travel far; limited coverage.
- Nearby furniture can get damp.
- Minerals from the water can settle around the humidifier.
Evaporative Cool Mist Humidifiers
If you leave a bowl of water at room temperature, it’ll slowly evaporate. That’s the basic principle behind evaporative humidifiers, also known as Evaporative Humidifiers. These devices have a large, mostly paper-based wick filter that soaks up water. A fan then draws in air from the room, which goes through the wet wick, causing the water to evaporate into the air. The resulting moist air is then blown out. This process cools the air slightly, but it’s barely noticeable.
- Can use tap water; the filter will trap minerals and impurities.
- Doesn’t produce a visible white mist.
- Vapor is light, covering a large area.
- Doesn’t dampen or stain nearby furniture.
- Pricier than ultrasonic models.
- Tends to be bulkier.
- Fewer manufacturers.
- You’ll need to change the filter regularly.
Steam Warm Mist Humidifier
The Steam Humidifier, also known as a Vaporizer, has internal heating elements that boil water and blow the steam into the room. It’s kinda like a funky-looking kettle (but you can’t drink from it). Unlike evaporative humidifiers, steam humidifiers emit boiled steam, whereas evaporative ones release evaporated steam. As of now, it seems Vicks might be the only brand still producing these. Some folks suggest adding table salt to the water. Doing this disrupts the bonds between water molecules, pushing them further apart and making it easier for them to vaporize. In this case, the salt acts as an “impurity”, but the impurity doesn’t necessarily have to be salt; some manufacturers recommend adding baking soda instead. If your tap water is hard, meaning it has plenty of minerals, you wouldn’t need to add any salt.
- Can use straight from the tap.
- Compatible with menthol scent pads or steam-specific cough remedies to soothe coughing.
- No need for filters.
- Too close to the steam nozzle can result in burns.
- Can’t turn off the nightlight feature.
- Limited number of manufacturers.
This type of humidifier is also of the evaporative kind. It’s installed right above the furnace and directly connected to the home’s water supply, eliminating the need for manual refills. When the heating system is on, the humidifier kicks in, and steam is blown into the house with the warm air. When the heat’s off, so’s the humidifier, saving both water and electricity. In the U.S., Aprilaire is a common brand. Depending on the size of your house, you can pick different models. These whole-house humidifiers typically require professional installation, but if you’re pretty handy, you might manage on your own. The internal filter just needs to be changed once a year.
- Uses the home’s water supply, so no manual refills needed.
- Humidifies the entire house without the need for individual room humidifiers.
- Set your desired humidity and forget about it.
- Filter can be replaced by the user.
- No noise inside the house.
- Professional installation required.
- A bit on the pricier side.
This type of device is known as an Air Washer or Air Purifier & Humidifier combo (2 in 1). It combines air purification and humidification. The air is drawn into the device and is cleaned by flowing through water or a filter, removing dust, mold spores, pollen, and other impurities. The humidification process is similar to that of an evaporative cool mist humidifier, releasing clean filtered air.
These devices are quite pricey. For instance, the Dyson, with its top-tier UV disinfection, can humidify, cool, purify the air, and eliminate formaldehyde, but it comes at a premium price.
Humidifier vs. Diffuser
Humidifiers are called, well, Humidifiers. Diffusers are meant for aromatherapy. They operate similarly, and a diffuser can be thought of as a mini-humidifier. Some standard humidifiers come equipped with essential oil trays, doubling as diffusers. Diffusers typically have smaller water tanks, making them perfect for bedside use, but if used as a humidifier, they require frequent refilling. Some versions atomize essential oils without the need for water, meaning they can’t be used for humidification.
Which Type of Humidifier to Choose?
Despite the numerous types mentioned above, the core operating mechanisms are ultrasonic and evaporative. Both have their pros and cons, and neither is definitively better; it depends on individual needs. If you’re set on getting a Dyson, you can probably skip the next details.
Evaporative humidifiers have a large water wick inside, making them bulkier compared to ultrasonic ones of the same capacity. They might not win beauty contests, but they cover a larger area since they emit more water into the air without leaving puddles on the ground.
2. Water Filling Method
Most have detachable tanks with a fill hole on the bottom. You flip the tank to fill it, screw on the lid, and flip it back. Some have peculiar shapes that make it hard to fill under a bathroom faucet, requiring a bathtub instead, which isn’t always convenient. Top-fill designs exist but are less common.
3. Tank Capacity
Tank capacity doesn’t equate to humidification efficiency or amount. Smaller tanks need refilling more often, while larger tanks can last days.
Both ultrasonic and evaporative humidifiers have fans, with the noise primarily coming from the fan motor. Ultrasonic models, having smaller fans, are quieter than their evaporative counterparts. However, even evaporative ones can be quiet if they use a good motor.
Ultrasonic humidifiers are ideal for bedrooms to ensure a quiet sleeping environment. Evaporative ones, being louder, are better for living areas where normal activities can drown out the noise. Generally, if the noise level is below 36 decibels, it won’t disturb your sleep. Still, tolerance varies among individuals. Some folks need complete silence, while others could sleep through a marching band.
5. Mineral Deposits
My biggest gripe is with ultrasonic humidifiers that don’t filter out minerals from the water. This can lead to white mineral deposits on furniture and floors, especially in areas with hard water. It doesn’t pose a health risk but can be a pain to clean up. From personal experience: I’d only recommend ultrasonic humidifiers in areas with soft water or for those with RO filters or who are willing to buy distilled water daily.
Evaporative humidifiers release vapor, not droplets. Minerals remain in the wick, not in the vapor. So, you won’t get those white deposits, but the wick will need regular cleaning or replacement, incurring an extra cost.
6. Cool Mist vs. Warm Mist
Whether you prefer cool or warm mist is a matter of personal preference. Some devices offer both functions; give them a try. Warm mist models can slightly raise room temperature, comfy in winter but might make your AC work harder in summer. Steam-based models are cheap but can scald if knocked over or if a child gets too close.
7. Bacterial Growth
Warm environments can promote bacterial and mold growth. Devices that spew water containing bacteria or mold pose health risks. Ultrasonic warm mist humidifiers need regular disinfection. In steam models, boiling kills off most microbes, but stagnant water can still breed bacteria.
8. Maintenance & Consumables
Humidifiers are relatively low-maintenance appliances, but regardless of the type, they still need regular cleaning. You can use a mix of white vinegar and water to clean the water tank and reservoir. Let it air dry afterward. Most households typically have white vinegar on hand, so this cleaning method is pretty cost-effective.
The additional expenses come from cleaning the mineral buildup in ultrasonic humidifiers. This includes buying water filters, distilled water, and descaling solutions. For evaporative humidifiers, the primary cost is replacing the filter. Ensure you get the right fit for your model. Changing it every three months means you’ll be spending about $50 to $60 a year just on filters. You could almost buy a new humidifier for that amount.
To remove scale, you can use white vinegar or a more efficient specialized cleaner.
9. Additional Features
Many humidifiers come with a nightlight feature, which I find quite handy. Others have features like a clock, thermometer, and even WiFi (really?). Whether you think it’s worth paying extra for these features is a personal choice.
Ultrasonic humidifiers operate very quietly, which I love. However, the mist they produce can dampen surrounding surfaces and furniture. I’ve bought the Crane ultrasonic humidifier twice because of its adorable design. They didn’t last more than two years, not because of product quality, but due to my mistakes. I placed the humidifier on a plastic shelf, which sagged under its weight, making it unstable. I also didn’t secure the water tank properly a few times, causing leaks that damaged the fan. If your local water is soft or you’re willing to use distilled water, I’d still recommend the Crane ultrasonic humidifier. They come in various designs.
Later, I tried the evaporative humidifier, specifically the Honeywell Cool Moisture Humidifier I mentioned earlier. It has two humidity settings. The high setting is a bit noisy, while the low setting is considerably quieter, which I use at night. Filling the tank is easy since the opening is larger than my fist, but it doesn’t have a nightlight. With the fan positioned on top, there’s no worry about accidental spills damaging the motor. After using it for two months, it worked wonders. My daughter hasn’t had nosebleeds in the middle of the night since. I’ve been using this humidifier for almost four years now, and it’s still going strong. However, it does require periodic filter replacements.
I also use a hygrometer to monitor indoor humidity. I bought the ThermoPro TP50 Digital Hygrometer. Keep in mind that household electronic hygrometers have an accuracy range of ±5%, so they’re just for reference.
