The Best Room Humidifiers to Up the Moisture in Your Home

Hello, my friend, hello again; today we come together to talk about The Best Room Humidifiers to Up the Moisture in Your Home and hope the blog can help you.

A heated home doesn’t have to go hand in hand with dry air. Pick out the best humidifier with the help from our guide, and you’ll rest comfortably indoors all year long.

Heating and air conditioning strip a home’s indoor air of its natural humidity. The result of uncomfortable dryness leaves skin feeling dehydrated, contributes to sinus and respiratory problems, and even promotes static electricity—that annoying shock that occurs upon crossing a carpeted room and touching the television.

A little added moisture in the air helps alleviate dust mites, reduces allergy symptoms, and soothes irritated nasal passages. In addition to a handful of household hacks, residents can rely on humidifiers to help the situation. Humidifiers have been around for decades, but today’s models offer more choices than ever before. We’ve done the legwork and found out what features buyers want most in humidifiers as well as which models they rate as the best humidifiers.

Keep reading to learn all about today’s room humidifiers, hear what experts have to say about these devices, and discover why we’ve selected these as top choices, depending on a person’s individual home and needs.

How We Chose the Best Room Humidifiers

Room humidifiers can do more than just improve the air quality. They can soothe dry skin, chapped lips, and help relieve a dry throat and common cold symptoms. However, there’s no one-size-fits-all solution, so consumers will want to check the variety available before making their choice.

During our own research, we looked at over 60 of the best room humidifiers currently available before landing on our carefully collated selection. We wanted to incorporate the various types, account for different room sizes, and choose models that were as easy to operate and maintain as possible. We looked for a range of humidifiers that would satisfy every need.

Price is always a consideration, and many of our picks offer excellent value for money. We also included a few high-end models for those who are prepared to pay a little extra for their comfort.

Evan Scobria, founder of Prime Home Humidity based in Bellingham, Washington, provides consumers with the latest information about humidifiers, dehumidifiers, and home humidity. “The mist created by room humidifiers protects wood floors and wood furniture from the damaging effects of overly dry air,” he says. In sum, the devices “are an effective remedy for low-humidity home environments.”

With so many quality models available, it isn’t easy picking a single best room humidifier. The Levoit Classic takes top spot for its wide-ranging feature set at a price that won’t break the bank.

A 6-liter (1.6-gallon) water tank provides a runtime of up to 60 hours in rooms from 215 to 505 square feet. It has a top opening that’s easy to fill—and easy to clean, too.

Best Bang For The Buck

Pure Enrichment MistAire Studio Ultrasonic Humidifier

Product Specs 

• Type: Ultrasonic
• Runtime: Up to 10 hours
• Coverage: Up to 175 square feet

Pros

• Compact model ideal for modest spaces at a very competitive price
• High and low mist settings provide up to 10 hours per refill
• Easy-to-fill top-loading model; comes with its own cleaning brush to help prevent mold

Upgrade Pick

Venta Filter-Free Evaporative Humidifier

Product Specs 

• Type: Cool mist
• Runtime: None provided (see above)
• Coverage: 600 square feet

Pros

• High-capacity unit can run for more than a week before it needs cleaning
• Simple top-mounted LED touch controls offer the choice of 3 speeds
• Runs safely on tap water and doesn’t have filters to clean or change

Cons

• It’s quite a bit more expensive than the other picks on our list

This Venta humidifier uses an unusual—yet very simple—design of a disk stack running in a 3-gallon bath of water. With no wick or filters to clean or replace, it’s a very low-maintenance machine. While many standard humidifiers require cleaning every day or so, the Venta only needs to be checked every 10 to 14 days, and the process is very straightforward.

This Venta model is rated for coverage of up to 600 square feet and offers three speeds for rapid humidification if desired. The company doesn’t provide a runtime but does suggest that the water level be checked daily. Should the water run out, the machine will automatically switch itself off.

Venta says their machine naturally reduces air pollutants. Another option is to consider a combined humidifier and air purifier, devices we explored

Best Design

Honeywell Designer Series Cool Mist Humidifier

Product Specs 

• Type: Cool mist
• Runtime: Up to 24 hours
• Coverage: None listed (see above)

Pros

• Sleek, modern, filter-free design with 3-stage illuminated water tank window
• Ergonomic handle provides rapid access to wide tank for easy refills
• Tactile scroll wheel allows adjustment of mist output, and an aromatherapy tray is included

Cons

• At the price, we’re surprised that there’s no humidistat—the machine is either on or off

Good design is about more than visual appeal. While we expect many will find the exterior of the Honeywell Designer Series humidifier attractive, there are several valuable ergonomic and practical elements we can recommend as well.

A clever handle in the lid gives easy access to the 1.25-gallon lift-out water tank, making it easy to fill and clean. An illuminated window lets users check the water level easily with three lighting settings: bright, dim, and off. There’s also an auto shutoff if it reaches empty. Below this is a thumbwheel that allows the mist output to be adjusted to personal preference. Honeywell claims the Designer Series humidifier can run for up to 24 hours, though rather than give a specific coverage area, the machine is simply described as for medium to large rooms.

Best Portable

Geniani Erie Portable Small Cool Mist Humidifier

Product Specs 

• Type: Cool mist
• Runtime: Up to 8 hours
• Coverage: Up to 65 square feet

Pros

• Compact and lightweight cordless model for humidification on the go
• Features include 1-button operation, USB charging, silent running, and night-light function
• Fits in most cup holders, so it can be used in vehicles

Cons

• It’s very popular, but fault reports suggest quality control might be hit and miss

Folks who need to humidify a variety of small spaces but only want to purchase one machine will want to take a close look at Geniani’s portable unit. It’s compact, has cordless operation, and weighs under 11 ounces. This travel-ready mini model will even fit into vehicle cup holders. USB charging can be done via a laptop, portable power pack, or household socket with an appropriate adapter.

Despite a tank that’s only 0.006 gallon, the Geniani will run for up to 8 hours. Coverage isn’t huge at 65 square feet, but it’s adequate for many modern motel rooms. It runs silently, so it won’t disturb sleep. There’s a built-in nightlight plus an auto shutdown that prevents damage if it dries out.

Quietest Operation

Everlasting Comfort Air Humidifier for Bedroom

Product Specs 

• Type: Ultrasonic
• Runtime: Up to 50 hours
• Coverage: Up to 500 square feet

Pros

• Uses “whisper-quiet” motor technology, which should allow for undisturbed sleep
• Straightforward dial control offers fully variable humidification to suit individual tastes
• Includes selectable night-light, drawer for aromatherapy oils, and 360-degree mist nozzle

Cons

• Some found it awkward to fill or to carry when full without spills

It’s never easy to define how quiet something is because we all hear differently. However, we do know that ultrasonic humidifiers like this one from Everlasting Comfort are typically quieter than fan-based alternatives. Although the manufacturer doesn’t give an actual decibel level, independent figures put it at under 35 decibels, which is the equivalent of the “whisper quiet” given in the description.

This low sound level is all the more impressive given the performance provided. Variable mist output gives a runtime anywhere from 22 to 50 hours from the 1.6-gallon water tank, and it’s rated for coverage of 500 square feet. An aromatherapy oil tray lets users scent the room either purely for pleasure or to combat seasonal allergies.

Best For Plants

Crane 4-in-1 Drop Ultrasonic Cool Mist Humidifier

Product Specs 

• Type: Ultrasonic
• Runtime: Up to 24 hours
• Coverage: Up to 500 square feet

Pros

• Adjustable 360-degree nozzle can aim humidification at groups of houseplants
• 3 speed settings to adjust output, plus easy-to-monitor water level
• Included sound machine delivers a choice of white noise, rain, or ocean waves to help sleep

Cons

• Not everyone likes the sounds or color-changing night-light, but both can be turned off

Those keen on houseplants probably know that most of them love increased humidity. While tropical plants may prefer a warm mist humidifier, these devices can cause discomfort for people. The Crane ultrasonic cool mist model is a solution that will keep both plant life and human occupants happy.

The 360-degree nozzle allows humidity to be directed where it’s needed most, and three speeds deliver the desired moisture level. With its clear 1-gallon tank, the Crane humidifier can run for up to 24 hours and provide coverage for up to 500 square feet. For nighttime use, it comes with a choice of three soothing sounds, and it has a night-light that changes colors. An aroma tray is included that can accept pads or oil.

Best For Small Rooms

Raydrop Cool Mist Small Room Humidifier

Product Specs 

• Type: Ultrasonic
• Runtime: Up to 9 hours
• Coverage: 220 square feet

Pros

• A low-cost model that’s under 5 inches in diameter, so it’s great for small spaces
• It has an impressive runtime for its size, even on full power
• Very quiet with an easy-to-use dial that offers precise mist control

Cons

• Cannot use essential oils, and a tray is recommended on wood tables or delicate surfaces

Finding a spot for a humidifier can be a challenge in small spaces like dorm rooms or campers. This Raydrop humidifier boasts a compact design that’s only 4.7 inches in diameter, so it should be easy to find a space for it in small or cluttered spaces. It also has a noise level of just 32 decibels, which is described as very faint, so it should not disturb sleepers.

The water tank is only 0.45 gallon, but that will provide mist for up to 9 hours at the machine’s highest output setting. The revolving control dial is easy to use while still offering accurate adjustment of mist output. It is rated for coverage of 220 square feet, so it actually has the capability to humidify good-size bedroom or home office spaces. It also comes with a budget-friendly price tag.
