Quick Verdict
The Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) takes this by a clear 2.7 points. Six gallons of invisible, dust-free humidity for a whole floor, at a filter-fed price. The Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) only makes sense if it wins on a category you care about more than the total.
The Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) and Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) are both closely matched humidifier models, and the Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) is $210 cheaper than the Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) ($39.99 vs $249.99). On Humidity Control, the Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) leads (8.5 vs 2.0/10) — whether there is a genuine closed-loop humidistat holding a setpoint, or just fixed output steps and a timer with a humidity label on it. On Output, the Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) leads (9.0 vs 3.0/10) — actual moisture put into the room per day in gallons or mL/hr, judged against the coverage the manufacturer claims — not the square-footage number on the box. On Runtime & Refill Interval, the Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) leads (9.5 vs 3.5/10) — how long a full tank really lasts at a useful output setting, rather than at the lowest setting the runtime is quoted for, and how painful the refill is. Overall, the Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) scores 8.1/10 across our 8 scoring categories versus 5.4/10 for the Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF). Below, we break down the full spec sheet, category-by-category scores, and exactly who should buy which one.
Side-by-Side Comparison
| Spec | Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) | Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) |
|---|---|---|
| Price | $249.99 | $39.99 |
| Release Year | 2023 | 2015 |
| Humidification Technology | Evaporative — a fan pulls room air through four wick filters standing in the reservoir; moisture leaves as invisible vapour, minerals stay in the wick | Ultrasonic cool mist — a piezo disc atomises water into a visible plume |
| White Dust & Mineral Aerosol | None. Evaporative humidifiers leave dissolved minerals behind in the wick — that is exactly why the wick goes stiff and crusty. Tap water is fine and no distilled water is needed | Yes, and Pure Enrichment says so in its own catalogue: the MistAire Decalcification Cartridge Filter is described as reducing "white dust from minerals in tap water". It is a $12.99 accessory, not included, and Pure Enrichment recommends changing it every six months. the EPA's "Use and Care of Home Humidifiers" states that ultrasonic and impeller humidifiers "are very efficient at dispersing minerals in tap water into the air" and that they "can disperse materials, such as microorganisms and minerals, from their water tanks into indoor air" |
| Tank Capacity | 6 gal / 22.7 L reservoir, filled through a supplied hose and funnel | 1.7 L / 0.45 gal — the smallest tank here after the Canopy |
| Rated Output per Day | Not published by Levoit as a gallons-per-day figure. The only published throughput is 6 gallons over "up to 72 hours", which works out at roughly 2 gal/day at the setting that runtime is quoted for | Published: 120 mL/hr on high and 60 mL/hr on low, i.e. 2.9 L/day and 1.4 L/day. That is a desk-scale output and Pure Enrichment is honest about it |
| Quoted Runtime (and at which setting) | "Up to 72 hours" — Levoit does not state the fan speed, but 6 gal / 72 h is about 2 gal/day, i.e. a low-to-mid setting. On high it is materially shorter | Up to 25 hours on LOW, up to 12 hours on HIGH — Pure Enrichment publishes both, which almost nobody else in this set does |
| Rated Room Coverage | Up to 3,000 ft² claimed with 360° circulation — the largest claim in this set, and one no portable unit can meet in a house with closed doors | Up to 250 ft² (Pure Enrichment) — the smallest claim here, and the only one that is consistent with the published output |
| Humidistat | Real closed-loop humidistat with a target-RH setpoint, plus app-side humidity history in VeSync | None. Two mist settings on a dial and an auto shut-off for a dry tank. No humidity sensor, no auto mode, no readout |
| Noise | 28-48 dB across the speed range per Levoit's material. The low end is genuinely bedroom-quiet; the top end is a fan you will hear | Not published as a decibel figure — Pure Enrichment says "whisper quiet". At 12W with no fan the noise is the ultrasonic hum and the water |
| Filters & Cartridges (Annual Cost) | Four wick filters, replaced together. Levoit's 4-pack is $39.99 and is listed as lasting up to 6 months, so about $40-80/yr depending on water hardness and hours. Dry Mode exists specifically to stretch that interval | Optional decalcification cartridge at $12.99, changed every six months — about $26/yr if you use it. Nothing is required for the unit to run, but running it on tap water without the cartridge is what generates the dust |
| Cleaning Burden & Dishwasher-Safe Parts | Low by console standards but not trivial: the reservoir is wide open and the parts nest for storage, but four wet wicks sit in standing water and Dry Mode has to be run to keep them from souring. Nothing is dishwasher-safe | Small, so it is quick, but the 1.7L tank neck is narrow and the supplied disk brush exists precisely because you cannot get a hand round the transducer. Nothing is dishwasher-safe. At 1.7L you are handling it daily anyway |
| UV / Antimicrobial Claim | No UV lamp and no antimicrobial claim on the water path. Levoit's hygiene answer is Dry Mode plus wick replacement, not a kill stage | None claimed. No UV, no antimicrobial coating, no bacteriostatic additive supported |
| Mist Temperature & Burn Risk | Cool, invisible vapour at room temperature — no burn risk. The evaporative process itself does not carry minerals or tank water into the air | Cool mist at room temperature — no burn risk, and no thermal kill step on the water |
| Warranty | 24 months | 60 months |
| Colors | White | White, Gray |
Category Scores
Freedom From White Dust
The Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) leads clearly here, 9.5 against 4.0 — a 5.5-point margin on the thing marketing never mentions. Ultrasonic humidifiers aerosolise whatever is dissolved in the water and deposit it as white dust on furniture — the EPA notes they are 'very efficient at dispersing minerals in tap water into the air', along with microorganisms from the tank. Evaporative and boiled-steam units do not do this at all. A high score means the technology cannot produce dust; a low score means you are buying distilled water for the life of the machine.. If that is what you are buying for, the Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) does not close the gap elsewhere.
Output
The Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) leads clearly here, 9.0 against 3.0 — a 6.0-point margin on actual moisture put into the room per day in gallons or mL/hr, judged against the coverage the manufacturer claims — not the square-footage number on the box. If that is what you are buying for, the Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) does not close the gap elsewhere.
Runtime & Refill Interval
The Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) leads clearly here, 9.5 against 3.5 — a 6.0-point margin on how long a full tank really lasts at a useful output setting, rather than at the lowest setting the runtime is quoted for, and how painful the refill is. If that is what you are buying for, the Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) does not close the gap elsewhere.
Cleaning & Access
The Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) leads clearly here, 6.5 against 6.0 — a 0.5-point margin on whether the tank opening takes an adult hand, whether any part is dishwasher-safe or boilable, and how realistic the manufacturer's stated cleaning interval is to actually keep to. If that is what you are buying for, the Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) does not close the gap elsewhere.
Running Cost
The Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) leads clearly here, 8.0 against 6.0 — a 2.0-point margin on wicks, demineralisation cartridges, antimicrobial additives, distilled water and electricity — everything you keep paying after the purchase. If that is what you are buying for, the Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) does not close the gap elsewhere.
Quietness
The Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) leads clearly here, 8.0 against 7.0 — a 1.0-point margin on noise at the setting people actually run it overnight, weighted toward independently measured figures over manufacturer claims. If that is what you are buying for, the Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) does not close the gap elsewhere.
Humidity Control
The Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) leads clearly here, 8.5 against 2.0 — a 6.5-point margin on whether there is a genuine closed-loop humidistat holding a setpoint, or just fixed output steps and a timer with a humidity label on it. If that is what you are buying for, the Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) does not close the gap elsewhere.
Safety Around Children
The Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS) leads clearly here, 9.0 against 8.5 — a 0.5-point margin on burn and scald risk from boiled or heated water, tipping hazard, and whether the hygiene story holds up in a nursery. If that is what you are buying for, the Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) does not close the gap elsewhere.

Pros & Cons
Levoit Superior 6000S Smart Evaporative Humidifier (LEH-S601S-WUS)
Pros
- +Evaporative design means no white dust and no distilled-water habit — you fill it from the tap with a hose
- +Six gallons and up to 72 hours is the longest unattended run here without stepping up to a plumbed whole-house unit
- +Dry Mode is a real answer to the wet-wick problem most evaporative units ignore
- +36W and 28dB at the low end make it far quieter and cheaper to run than an AC-motor console of similar output
- +Collapses with wheels and a storage bag, which matters for something this big six months of the year
Cons
- −$249.99 plus roughly $40-80 a year in wicks — the highest first-year cost of any evaporative unit here except the Venta
- −The 3,000 ft² claim is a still-air marketing number; a single portable unit will not humidify a 3,000 ft² house with interior doors shut
- −Levoit publishes no gallons-per-day output at all, so you have to back it out of the 6 gal / 72 h runtime
- −Four wicks standing in six gallons of water is a lot of wet surface — skip Dry Mode and skip the wick changes and it will smell
- −Physically large even collapsed, and there is nowhere on the unit to see humidity without the phone
Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF)
Pros
- +A five-year warranty at $39.99, which no other humidifier in this comparison comes close to
- +Publishes both output (120/60 mL/hr) and runtimes for both settings — rare honesty at this price
- +Pure Enrichment openly sells a cartridge described as reducing "white dust from minerals in tap water", so the problem is at least acknowledged
- +12W and auto shut-off; small enough to sit on a desk without dominating it
Cons
- −1.7L and 120 mL/hr is a desk humidifier, not a bedroom one — a full tank on high lasts twelve hours and covers 250 ft² at best
- −Ultrasonic, so it makes white dust; the demineralisation cartridge that reduces it is a $12.99 accessory sold separately on a six-month cycle
- −No humidistat of any kind — two settings on a dial and nothing that senses the room
- −Narrow tank neck means you clean the transducer with the supplied brush rather than your hand
- −No antimicrobial or UV stage, and Pure Enrichment publishes no noise figure
