What is the best humidifier to buy?

The best humidifier is the type that suits your room and how much cleaning you will really do, with a built-in humidistat so it stops before the air gets too damp. The EPA groups home humidifiers into four main types. Here is how they compare, based on the EPA's guidance:

Type	How it works (per the EPA)	Minerals and microbes in the air	Things to know
Ultrasonic	Creates a cool mist with ultrasonic vibrations	Among the highest dispersal, per the EPA	Quiet; use distilled or low-mineral water to avoid white dust
Impeller ("cool mist")	Throws a cool mist off a fast-spinning disk	Among the highest dispersal, per the EPA	Clean often
Evaporative	A fan blows air through a wet wick, belt or filter	Generally lower; not expected to disperse substantial minerals	Moisture is invisible; the wick or filter needs replacing
Steam vaporizer (including warm mist)	Heats water to make steam; warm mist models cool the steam before it leaves	Generally lower; not expected to disperse substantial minerals	Keep out of children's reach, as steam and hot water may cause burns

Humidifiers also come in different sizes: portable units for one room, console units designed for floor use, and central humidifiers built into heating and cooling systems for the whole house, per the EPA.

What to look for:

• Humidity sensor and auto mode. The EPA says some humidifiers have a built-in humidistat you can set to the right level. That stops the room going above 50%.
• Tank size and runtime. A bigger tank means fewer refills, but you should still empty and refill daily.
• Easy cleaning. A wide tank opening or top-fill design makes the EPA's every-third-day cleaning easier.
• Room coverage. Makers list coverage in square feet; match it to your room.

The short version: pick the type for your room, set it to 50% or below, and clean it on the EPA's schedule.

Best humidifier 2026: models and stores in the US

For 2026, the best humidifier for most US homes is a sensor-equipped model from a brand that lists coverage, runtime and noise clearly, bought where you can go through ShopBack first. Dreo is a good example of how makers describe their range. According to Dreo's own product listings at the time of writing:

Dreo model	Type (per Dreo)	Tank	Coverage and runtime (per Dreo)
Humidifier 306S	Ultrasonic	3 L	About 300 sq ft; up to 30 hours in sleep mode
Humidifier 311	Ultrasonic	4 L	Up to 32 to 40 hours, depending on the listing; Dreo lists 28 dB
Smart Humidifier 713S	Top-fill cool and warm mist with humidity sensor	6 L	Up to 60 hours
Smart Humidifier 717S	Warm and cool hybrid	8 L	Up to 80 hours; Dreo lists 28 dB
Smart Humidifier 774S	Evaporative, mist-free	10 L	Up to 50 hours
Smart Humidifier 747S	Top-fill cool mist	11 L	About 700 sq ft; up to 100 hours; Dreo lists 21 dB

Dreo is on ShopBack US. Other US stores on ShopBack US that sell humidifiers from several brands include Walmart, Target, Home Depot and Lowe's.

Dreo vs Target: best humidifier price comparison

Buying direct from Dreo and buying at Target each have strengths: Dreo sells its own full range, and Target sells several brands side by side with options such as store pickup. For a fair comparison, look at the same model on the same day and compare the final price after shipping. Then compare the effective price, which is what you pay minus any cash that comes back through ShopBack. Both Dreo and Target have ShopBack US pages.

What is the best humidifier for a baby's room?

A cool-mist evaporative humidifier usually fits the EPA's guidance best for a baby's room, because the EPA warns that steam can cause burns and that ultrasonic and impeller units disperse the most minerals and microorganisms. Whatever type you pick, the EPA's care routine matters most in a nursery.

How to choose and use one safely:

• Avoid hot steam near children. The EPA says to keep steam vaporizer humidifiers out of the reach of children, since steam and boiling water may cause burns.
• Use distilled or low-mineral water. The EPA recommends low-mineral water, especially in ultrasonic and impeller units.
• Clean on schedule. Empty, dry and refill daily, and clean every third day, per the EPA.
• Do not over-humidify. Keep the room at or below 50%. If water condenses on windows or walls, the EPA says to move the humidifier, lower its setting or use it less.
• Place it safely. Keep the unit and its cord out of reach of the crib, and keep nearby carpet and curtains from getting damp.
• Choose a quiet model. Makers list noise in decibels; lower numbers suit a sleeping room.

If your baby has a cold or breathing concern, ask your pediatrician before using a humidifier. When you are ready to buy, open ShopBack, tap the store, then check out.

Best humidifier for baby: best deals in the US for 2026

For a nursery humidifier, the best deal is the safest suitable model at the lowest effective price, and big sale weekends are a good time to compare. In 2026, Black Friday is Friday, November 27 and Cyber Monday is Monday, November 30. Big retailers and appliance brands often discount home and baby items then.

Ways to pay less:

• Compare the same model across Dreo, Target and Walmart on the same day.
• Count running costs. Evaporative models need replacement wicks or filters, and distilled water is an ongoing cost.
• No code needed. Go through ShopBack before you pay and part of what you spend comes back as Cashback.

What is the best dehumidifier to buy?

The best dehumidifier to buy is an ENERGY STAR certified model with enough capacity, in pints per day, for how damp your space is. ENERGY STAR says a certified dehumidifier uses more efficient coils, compressors and fans to remove the same moisture as a similar conventional unit while using 20% less energy. The EPA advises keeping indoor humidity below 60%, ideally between 30% and 50%, to limit mold.

ENERGY STAR's capacity guide for portable dehumidifiers:

Condition without a dehumidifier (per ENERGY STAR)	Small to medium room (under 2,000 sq ft)	Large room (over 2,000 sq ft)
Slightly to moderately damp: feels damp, musty odor at times (50% to 75% relative humidity)	20 to 30 pints per day	30+ pints per day
Very damp: always feels and smells damp, damp spots on walls and floors (75% to 90%)	25 to 40 pints per day	40+ pints per day
Wet: walls or floor sweat, seepage, or laundry drying (90% to 100%)	30 to 50 pints per day	50+ pints per day

ENERGY STAR adds that it is better to oversize than undersize.

Other features to compare, according to ENERGY STAR:

• Water removal. Most portable units use a bucket with a full warning light and automatic shutoff. Some take a hose so water drains to a floor drain or sump pump, which suits basements.
• Low-temperature use. Frost can form on the coils below 65°F. If your basement is cool, look for a model rated for lower temperatures or with an anti-frost sensor.
• Efficiency. Efficiency is measured as an integrated energy factor in liters of water removed per kilowatt-hour; a higher number is more efficient.
• Whole-home units. In humid climates with central air, a whole-home dehumidifier connected to your ducts may suit better; ENERGY STAR says these are installed by an HVAC professional.

Check ShopBack before you buy a dehumidifier, and compare the effective price, not just the shelf price.

Frequently asked questions

What is the best humidifier to buy?

The best humidifier is one sized to your room, easy to empty and clean every day, and fitted with a humidity sensor so the room stays at or below 50% relative humidity, the level the EPA advises not to exceed. Evaporative and steam types disperse fewer minerals than ultrasonic ones, per the EPA. Open ShopBack, tap the store, then check out.

What is the best humidifier for a baby's room?

A cool-mist evaporative model usually fits the EPA's guidance best for a nursery. The EPA warns that steam vaporizers should be kept out of children's reach because steam and boiling water may cause burns, and says ultrasonic and impeller units disperse the most minerals and microorganisms. Use distilled water, clean it often, and ask your pediatrician.

What is the best dehumidifier to buy?

The best dehumidifier is an ENERGY STAR certified model with enough capacity, measured in pints per day, for your room's dampness. ENERGY STAR says certified units use 20% less energy than similar conventional ones and that it is better to oversize than undersize. Check ShopBack before you buy at Home Depot or Lowe's.

What humidity level should my home be?

The EPA advises keeping indoor relative humidity below 60%, ideally between 30% and 50%, and not humidifying above 50%. A hygrometer, which the EPA says costs about $10 to $50 at hardware stores, shows you the level so you can set your humidifier or dehumidifier.

What is the difference between cool mist and warm mist humidifiers?

Cool mist humidifiers include ultrasonic, impeller and evaporative types. Warm mist humidifiers are a type of steam vaporizer that heats water and cools the steam before it leaves the machine, according to the EPA. Steam and evaporative types disperse fewer minerals, while steam units need care around children because of burn risk.

How often should I clean a humidifier?

The EPA advises emptying the tank, wiping it dry and refilling portable humidifiers daily, and cleaning them every third day to remove scale and film. Unplug the unit first, follow the maker's instructions, and rinse well after any cleaning product. The EPA suggests a 3% hydrogen peroxide solution if the maker gives no advice.

Can I use tap water in a humidifier?

The EPA recommends water with low mineral content, such as distilled water, especially in ultrasonic and impeller humidifiers, because those types can release minerals from the water into the air. Evaporative and steam humidifiers are not expected to disperse substantial amounts of minerals, according to the EPA.

What size dehumidifier do I need?

ENERGY STAR suggests 20 to 30 pints per day for a slightly to moderately damp small to medium room under 2,000 square feet, 25 to 40 pints for a very damp one and 30 to 50 pints for a wet one, with higher capacity for larger rooms. If you are replacing a unit, judge by how much water you empty each day.

Is Dreo or Target better for buying a humidifier?

Both work well for different reasons. Dreo sells its own humidifiers direct, including ultrasonic, evaporative and warm and cool hybrid models, while Target sells several brands with options such as store pickup. Compare the same model's price after shipping, and go through ShopBack before you check out at either.

What is the effective price of a humidifier after ShopBack?

Your effective price is what you pay minus the cash ShopBack returns. The live rate is shown on each store's ShopBack page.
