The Best Warm and Cool Mist Humidifiers (2026)

Two modes are the easy part. Control is the product. Plenty of humidifiers offer warm and cool. What makes the Levoit LV600S worth $109.00 is that it also has a humidistat, so it targets a relative humidity level and modulates output to hold it, rather than converting 6 L of water into mist at a fixed rate and stopping only when it runs out.

Levoit publishes 6 L, which covers a long night with margin and often a second one. The warm mode is genuinely more pleasant in a cold room and gets the antimicrobial benefit of heating the water on the way out; the cool mode costs less to run. Being able to switch by app, from bed, is a smaller feature that turns out to matter.

Nothing goes in the tank, ever: no VapoSteam, no essential oils. If you want scent, use a diffuser, and if you want menthol vapor you need a steam vaporizer with a medicine cup, which we cover in the cold and congestion ranking. Detail is the Levoit LV600S review, and the head to head buyers ask about is LV600S vs the Vicks warm mist.

Not everything needs to be on your phone. The Levoit LV600HH at $99.99 is the non-smart version of our pick: the same published 6 L tank, the same warm and cool modes, operated from the unit itself. No account, no app updates, no device that stops working when a server changes.

What you lose is genuine: no remote adjustment, no scheduling, and no humidity monitoring from another room. If those matter to you, spend the $9.01 on the LV600S. Levoit also sells a classic warm and cool unit in white at $99.99 and a smart symptom relief version at $89.99. The brand overview is the Levoit humidifier review.

Buying the badge, honestly assessed. The Honeywell HWC775B Dual Comfort at $114.99 offers both cool and warm mist. Honeywell's reputation in humidifiers was built on its evaporative line rather than its hybrids, so this unit competes on the brand's longevity and its wide retail service network.

If evaporative rather than hybrid is what you actually want from Honeywell, the Cool Moisture HCM-350 class unit at $76.42 is the model that made the brand in this category, publishes 1.1 gallons, and leads our cool mist ranking. It needs Filter A replacements at $29.21 for three. Our brand take is the Honeywell humidifier review.

The most familiar brand, at the least familiar price. The Vicks Dual Comfort at $114.61 sits at the top of the Vicks humidifier range and offers both cool and warm mist. Vicks is the name everybody reaches for in this category, largely on the strength of its steam vaporizers rather than its hybrids.

Vicks publishes no capacity, humidistat confirmation or decibel figure for this model that we can verify, so those rows stay blank. At this price the LV600S at $109.00 publishes more and costs less, which is the comparison we would make. Our brand take is the Vicks warm mist review, and the far cheaper V745 leads our warm mist ranking.

The clean value comparison on this page. The Dreo 6 L smart warm and cool at $79.94 publishes the same headline specification as the $109.00 LV600S: 6 L, both mist modes, smart control with humidity targeting. That is a $29.06 gap for a matched spec sheet.

Dreo's decibel figures elsewhere in the range are the best in our catalog, which is worth knowing: the 747S 11 L at $99.99 publishes 100 hours and 21 dB, and the 3 L at $29.97 publishes 26 dB. See best quiet humidifier and the Dreo humidifier review.

The convenience argument. The Crane 4.5 L warm and cool top fill at $87.94 publishes 4.5 L and fills from above, which means you never carry a heavy tank to a sink and invert it. On a 4.5 L unit that is not a small thing: a full tank is over nine pounds of water.

Crane does not publish a humidistat confirmation or a decibel figure for this model that we can verify, so those rows stay blank, and 4.5 L is 1.5 L less than the three 6 L units here. Crane's smaller warm mist units are covered in our warm mist ranking and its nursery line in best humidifier for baby. The brand take is the Crane humidifier review.

Nearly the same money, a different published number. The Levoit 6 L smart warm and cool with 60 hour runtime at $109.99 publishes the same 6 L tank as the LV600S plus an explicit 60 hour runtime rating, for $0.99 more.

Sixty hours means filling it roughly twice a week rather than every night, which is the difference between a device that stays in service through a whole winter and one that ends up in a cupboard. If you want the simpler, cheaper version of the same idea, Levoit's smart symptom relief unit is $89.99.
