What to know about Levoit LV600HH

The non-smart sibling of the LV600S: a 6 L, filterless, bottom-fill hybrid ultrasonic unit with warm/cool mist, auto mode and remote, rated 430–753 sq ft. Reviewed measured the biggest humidity increase of any unit it tested (38.5%), and NBC Select calls it the best cool-mist pick for large rooms. A good-value way to get high output if you will use distilled water.
Editorial notes

Why it stands out

Why we like it

Reviewed measured the biggest humidity increase of any unit it tested, 38.5%, and NBC Select picks it for large rooms. It is the lowest-priced pick in this guide and needs no filters.

If you want the output of the LV600S without paying for the app and top-fill design, this is the straightforward alternative.

What to know

Skip it if you dislike hassle. The tank is bottom-fill and must be flipped to refill, BabyGearLab found it harder to clean, and it needs distilled water.
Performance

Score breakdown

Hygiene & Ease of Cleaning

How easy it is to fully disassemble, reach and dry every wet surface. Covers dishwasher-safe or boilable parts, mold-inhibiting features, and parts count. Weighted heavily by BabyGearLab (35%) and stressed by Babylist, Forbes and RTINGS.

4.8
Ultrasonic has the highest dispersal per EPA; BabyGearLab says it is somewhat harder to clean.
Humidifying Performance

Ability to raise and hold nursery humidity in the 40–50% range: tested output, coverage for the room size, overnight runtime per tank, and humidistat or auto-mode accuracy.

8.0
Largest gain in Reviewed testing; 6 L tank, 753 sq ft max.
Quiet & Sleep-Friendly

Measured or rated noise, absence of gurgles and beeps, dimmable or switch-off lights, and nursery extras like a red night light or white noise that help rather than disturb sleep.

6.8
No verified dB figure; no sleep-mode evidence.
Health, Safety & Materials

Cool-mist or evaporative design (no burn risk), stainless or BPA-free water-contact materials, and white-dust/mineral mitigation such as demineralization filters or evaporative design. Also covers tip and leak resistance, auto shut-off, and any recalls or regulatory warnings.

5.5
CARB/Intertek marks; tap water causes white dust and PM2.5.
Ease of Use

Filling (top-fill vs flip-tank), controls usable in the dark, app reliability, leak-free refills, and how easy it is to move or place.

6.5
Remote and auto mode; bottom-fill means flipping the tank.
Value

Street price plus ongoing costs (filters, cartridges), weighed against warranty length and performance.

7.6
$99.99 with no filters, but distilled water and warm-mode power add cost.
