Side-by-Side Comparison
| Spec | Dreo HM713S 6L Smart Humidifier | Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) |
|---|---|---|
| Price | $89.99 | $39.99 |
| Release Year | 2023 | 2015 |
| Humidification Technology | Ultrasonic, sold as "cool and warm mist". The warm mode pre-heats the water before the piezo disc atomises it — it does not boil it | Ultrasonic cool mist — a piezo disc atomises water into a visible plume |
| White Dust & Mineral Aerosol | Yes, in both modes. Warming the water does not change the mechanism: a piezo disc still aerosolises everything dissolved in it. 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". Dreo fits a mineral-absorption pad and sells no first-party replacement, so the aftermarket pads on Amazon are third-party and unverified | 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 L / 1.58 gal, top-fill | 1.7 L / 0.45 gal — the smallest tank here after the Canopy |
| Rated Output per Day | Published, unusually: 300 mL/hr in cool mist, 500 mL/hr in warm mist — 7.2 L/day and 12 L/day respectively if run continuously. Both exceed the 6 L tank, so the 60-hour runtime cannot be a high-output figure | 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 60 hours" — arithmetic settles this one. 6 L at the published 300 mL/hr cool-mist rate is 20 hours, and at 500 mL/hr warm it is 12. The 60-hour claim implies about 100 mL/hr, i.e. the lowest setting only | 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 | Not published by Dreo on the product page — the only sizing language is the retail headline "for Large Room". Dreo publishes output instead, which is arguably the more useful number | 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. Dreo rates the sensor at ±5% precision with a 30-90% RH adjustable target, plus manual, auto and sleep modes and 30 days of app-side history | 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 dB claimed by Dreo — a manufacturer figure with no independent measurement published, and comparable ultrasonics measure several dB higher in third-party testing | 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) | A mineral-absorption pad sits in the tank. Dreo does not sell a first-party replacement pack; the only replacements listed are third-party multi-packs, so budget is unclear and the pad does not eliminate white dust regardless | 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 | Top-fill opening takes a hand and the aroma tray lifts out, but the warm-mist heater adds a scale surface an ordinary cool-mist ultrasonic does not have. Nothing is dishwasher-safe. Dreo ships a cleaning guide and brush in the box, which is more than most | 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 | None claimed. No UV lamp, no antimicrobial coating. The warm mode is not hot enough to sterilise anything | None claimed. No UV, no antimicrobial coating, no bacteriostatic additive supported |
| Mist Temperature & Burn Risk | This is the trap. Dreo's own spec says warm mode "reaches 86°F in 5 minutes" — 30°C, barely above body temperature. That is comfort, not sterilisation: a genuine warm-mist unit boils at 212°F. It also means the 280W warm mode buys you no hygiene benefit at all, and the mist is not sterile | Cool mist at room temperature — no burn risk, and no thermal kill step on the water |
| Warranty | 12 months | 60 months |
| Colors | Silver, Blue | White, Gray |
Category Scores
Freedom From White Dust
The Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) leads clearly here, 4.0 against 2.5 — a 1.5-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 Dreo HM713S 6L Smart Humidifier does not close the gap elsewhere.
Output
The Dreo HM713S 6L Smart Humidifier leads clearly here, 7.5 against 3.0 — a 4.5-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 Dreo HM713S 6L Smart Humidifier leads clearly here, 8.0 against 3.5 — a 4.5-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 Dreo HM713S 6L Smart Humidifier 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 Dreo HM713S 6L Smart Humidifier does not close the gap elsewhere.
Quietness
The Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) leads clearly here, 8.0 against 7.5 — a 0.5-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 Dreo HM713S 6L Smart Humidifier does not close the gap elsewhere.
Humidity Control
The Dreo HM713S 6L Smart Humidifier 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 Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier (PEHUMIDIF) leads clearly here, 8.5 against 7.5 — a 1.0-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 Dreo HM713S 6L Smart Humidifier does not close the gap elsewhere.

Pros & Cons
Dreo HM713S 6L Smart Humidifier
Pros
- +One of the very few humidifiers at any price that publishes a real output figure — 300 mL/hr cool, 500 mL/hr warm
- +Genuine closed-loop humidistat rated ±5% with a 30-90% setpoint range and 30 days of app history
- +6L top-fill tank plus app, Alexa and Google control for $89.99
- +Because output is published, you can actually compute the refill interval instead of trusting a runtime claim
Cons
- −"Warm mist" tops out at 86°F by Dreo's own spec — warm water, not steam. It does not sterilise, and it costs 280W against 26W in cool mode
- −Ultrasonic in both modes, so it aerosolises minerals as white dust; the mineral-absorption pad reduces scale, it does not stop dust
- −The 60-hour runtime and the published 300-500 mL/hr output contradict each other — 6L at 300 mL/hr is 20 hours, so 60 hours is the lowest setting
- −Dreo sells no first-party replacement mineral pad; the only options are unverified third-party multi-packs
- −Twelve-month warranty and no published coverage figure or independent noise measurement
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
