5 Criteria to Look For Before Buying a Levoit Humidifier
Key buying criteria so you get the right fit the first time.
Cool Mist (Ultrasonic or Evaporative) vs Warm Mist
Cool mist humidifiers come in two types: ultrasonic models use a vibrating plate to create a fine mist, while evaporative models use a fan to blow air through a wet wick filter. Warm mist humidifiers instead boil the water before releasing it as vapor, which kills bacteria and mold in the water during the boiling process and runs quieter since there's no fan, but uses more electricity and isn't well-suited to a large room since it has no fan to circulate the moisture. Warm mist suits a small bedroom or office where quiet matters most; cool mist covers a larger area more efficiently.
Tank Cleaning Frequency and Mold Risk
The mold and bacteria risk with any standing-water humidifier is real, not a minor concern: manufacturers and health sources recommend cleaning the tank every two to three days minimum, since stagnant water is exactly the environment bacteria and mold need to grow, and an ultrasonic or evaporative unit will then disperse whatever is growing in that water directly into the air. A wide-opening tank and dishwasher-safe parts make this maintenance realistic to keep up with; a narrow, hard-to-reach tank often ends up cleaned far less often than it should be.
White Dust From Ultrasonic Models and Hard Water
Ultrasonic humidifiers can disperse fine mineral particles from tap water as a visible white dust that settles on nearby furniture, since the vibrating plate doesn't filter out dissolved minerals the way an evaporative wick does. Using distilled or demineralized water instead of tap water largely eliminates this issue with ultrasonic models. Evaporative humidifiers don't have this problem at all, since minerals get trapped in the wick filter rather than released into the air, which is worth knowing if you have hard water and don't want to keep buying distilled water.
Tank Capacity vs Room Size and Refill Frequency
Bigger tank capacity means fewer refills, but also more size and weight to deal with when it does need refilling: a 1-gallon humidifier is compact and easy to carry to the sink, but may need daily refills in a dry room, while a 3-gallon-plus console model runs for days at a time but is heavier and bulkier to move and fill. Choose based on how often you're realistically willing to refill it, not just the room-size coverage number on the box.
Filter vs Filterless Design and Ongoing Cost
A humidifier with a replaceable filter (common on evaporative models) traps minerals and some airborne particles, but that filter needs periodic replacement, an ongoing cost the upfront listing price doesn't reflect. A filterless humidifier (typically ultrasonic) skips that recurring expense but requires more diligent manual tank cleaning to prevent mineral buildup and bacteria growth, since there's no filter catching anything before it's dispersed. Factor in filter replacement cost over a year, not just the sticker price, when comparing a filtered model against a filterless one.

Frequently Asked Questions
Is a cool mist or warm mist humidifier better?
Warm mist humidifiers boil the water, killing bacteria in the process and running near-silently, but use more electricity and work best in a small room since they have no fan; cool mist humidifiers (ultrasonic or evaporative) use less power and cover larger rooms more effectively, since they distribute moisture with a vibrating plate or fan instead of relying on steam alone.
How often do I need to clean a humidifier?
At least every two to three days, since a standing-water tank left uncleaned becomes a real breeding ground for bacteria and mold that then gets released into the air; check for a wide-opening, dishwasher-safe tank design, since a hard-to-clean tank often just doesn't get cleaned as often as it should.
Why does my humidifier leave white dust on furniture?
This happens with ultrasonic humidifiers using hard tap water, since the vibrating plate disperses dissolved minerals into the air along with the moisture; switching to distilled water largely fixes it, or choose an evaporative model instead, which traps minerals in its wick filter and doesn't produce white dust.
What size humidifier tank do I actually need?
It depends on how often you're willing to refill it: a 1-gallon tank is compact but may need daily refills in a dry room, while a 3-gallon-plus console tank runs for several days between refills but takes up more space and is heavier to carry and fill.
Do I need a humidifier with a filter?
A filtered evaporative model traps minerals but needs periodic filter replacements, an ongoing cost beyond the sticker price; a filterless ultrasonic model skips that expense but requires more diligent manual tank cleaning, since nothing is filtering the water before it's dispersed as mist.
Can a humidifier help with dry skin or allergies?
Adequate indoor humidity (typically 30 to 50 percent) can ease dry skin, irritated sinuses, and some allergy symptoms caused by overly dry air, but a poorly maintained humidifier can worsen indoor air quality by dispersing mold or bacteria from an uncleaned tank, so the maintenance routine matters as much as owning one.
