Search for Levoit air purifier decibels and you will find a figure on almost every product page Levoit runs. That is more than many brands publish. What the pages do not make plain is that the low figure does not always describe the same setting, and that changes how you should read it.
We read the US product page and user manual for every air purifier on Levoit's US store. Seventeen current models carry a noise figure. This page lists all of them, explains what Levoit's labels mean, and ranks each model only against others whose figure describes the same thing.
Our picks are listed above, with full specifications for each.
Every Levoit spec table gives a range in the form "Noise Level: 22-50dB". Levoit does not name the setting at either end, does not state a measuring distance, and does not name a test standard. The figures are in dB. One manual, for the Eleva 500X, writes the same range as dB(A).
The low end is where the labels differ. Levoit's summaries use three kinds of wording:
- Tied to Sleep Mode. The Eleva 300X page says "20dB whisper quiet in Sleep Mode". The Core 200S-P says it "operates with noise levels as low as 27dB" in Sleep Mode. The LV-H128 says "Sleep Mode: Rest undisturbed with noise levels as low as 24dB."
- Tied to the lowest fan speed. The Sprout is "as quiet as 22dB on the lowest fan speed". The Vital 100 and LV-H132 use the same wording, at 23dB and 25dB.
- Not tied to a setting. Most models say "QuietKEAP Technology: Keeps noise levels as low as" a figure, and stop there.
In every Levoit manual we read that describes Sleep Mode's fan, it is a separate speed below low, so a Sleep Mode figure and a lowest-fan-speed figure describe different fan speeds. We never rank one against the other. Winix prints just one figure per model, for the slowest speed, and our Winix air purifier decibels page shows that on ten models its manual makes that speed Sleep Mode.
The top end is never labelled. Levoit's manuals say the highest speed, turbo on most models, is the loudest, so the top of the range most likely describes it, but Levoit does not say so. We rank top figures against each other as the top of Levoit's printed range, and only within a room-size group, because a bigger unit moves more air at full speed.
Low end tied to Sleep Mode, quietest first
- Eleva 300X: 20dB in Sleep Mode; range 20-50dB; 250 sq ft at 4.8 ACH.
- LV-H128 desktop: 24dB in Sleep Mode; range 24-36dB; 47 sq ft at 4.8 ACH.
- Core 200S-P: 27dB in Sleep Mode; range 27-48dB; 140 sq ft at 4.8 ACH.
Low end tied to the lowest fan speed, quietest first
- Sprout: 22dB on the lowest fan speed; range 22-50 dB; smoke CADR 85 CFM.
- Vital 100: 23dB on the lowest fan speed; range 23-50dB; 163 sq ft at 4.8 ACH.
- LV-H132: 25dB on the lowest fan speed; the spec table gives the top as at most 50dB, printed with a less-than-or-equal sign; 54 sq ft at 4.8 ACH.
Low end not tied to a setting, lowest first
- Vital Pet Pro: 21-53 dB, with no "as low as" claim; 229 sq ft at 4.8 ACH.
- Core 300S-P: 22-50dB on the product page, 22-54.5dB in the manual; 219 sq ft.

- Core 400S-P: 22-52dB in the spec table, but "as low as 24dB" in the summary and 24-52dB in the manual; 358 sq ft.
- Vital 100S-P: 23-52dB; 222 sq ft.
- Vital 200S-P: 23-54dB; 388 sq ft.
- Core 300-P: 24-54.5dB; 222 sq ft.
- Core P350-P pet care: 24-50dB; 217 sq ft.

- Core 600S-P: 26-55dB; 606 sq ft.
Levoit also sells the Vital Pet, but its US product page gives no noise figure, so it is not ranked here.
Top of the range, by room size
For a small room, rated under 140 sq ft at 4.8 air changes an hour, the LV-H128 tops out lowest at 36dB, then the Core Mini-P at 44dB and the LV-H132 at 50dB or less. These are desk-sized units.
For a bedroom, rated from 140 to 250 sq ft (the Sprout gives no room size, so it sits outside these groups), the Core 200S-P is lowest at 48dB. The Eleva 300X, Vital 100, Core P350-P and Core 300S-P product page all list 50dB, then the Vital 100S-P at 52dB, the Vital Pet Pro at 53 dB and the Core 300-P at 54.5dB.
For a large room, rated above 350 sq ft, the Eleva 500X and Core 400S-P tie at 52dB, then the Vital 200S-P at 54dB, the Core 600S-P at 55dB and the EverestAir-P at 56dB on its product page. Our large-room air purifier guide sets these beside other brands' bigger units.
What the gaps mean
Decibels are logarithmic. Roughly every 10 dB sounds about twice as loud, so the gap between 20dB in Sleep Mode and 50dB at the top of the same Eleva 300X is large: the top end sounds several times louder. A gap of 2 or 3 dB between two Levoit models is small, and with no distance stated it may be no gap at all. Our decibel chart sets published appliance figures beside everyday sounds such as a whisper and a fridge.
Levoit's quiet features, by their real names
QuietKEAP Technology. This is the name Levoit gives its low-noise design. The pages say it "Keeps noise levels as low as" a figure, or "reduces noise levels to as low as" one. Levoit does not say what it changes in the machine.
Sleep Mode. Every Levoit manual we read describes it the same way: it "operates quietly by using a fan speed lower than low speed", or lower than fan speed 1. On the Core 300S-P, Core 400S-P and both Eleva models, Sleep Mode turns the display off after 3 seconds; on the Core 600S-P, EverestAir-P and both Vital S models, after 6 seconds. The Core 200S-P manual says the display "will be completely turned off within 6 seconds", though its night light stays on until you turn it off.
Display Off. A button, or an app setting on the Vital models, that turns off the button and indicator lights. The Check Filter Indicator stays lit when a filter is due.
Auto Mode, and how it ramps. Auto Mode reads a dust sensor and sets the fan to match. On the Core 300S-P, Core 400S-P, Core 600S-P, EverestAir-P and Vital S models, the manual's chart runs from Sleep Mode for Very Good air up to High for Bad air. The Core 400S-P, Core 600S-P and Vital S manuals say Auto Mode does not use turbo, and the EverestAir-P manual says it does not use Turbo Mode. The Sprout and Eleva charts run from fan speed 1 to 4, so they can reach the top speed. A burst of cooking smoke can take any of them up several steps in the night.
Quiet Auto Mode. An app setting. On the Core 300S-P, it "never uses the highest fan speed to avoid making too much noise." On the Core 400S-P, it "uses medium fan speed instead of the high or turbo fan speeds, even when the air quality is poor." On the Sprout it uses "medium fan speed (level 3)". The Eleva 300X and 500X manuals list it too.
Light Detection. On the Vital 100S-P and Vital 200S-P, with the room dark, Auto Mode and Pet Mode "will not use the high or turbo fan speed to avoid making too much noise." It is off by default.
Baby Sleep Mode. Only on the Sprout. The manual says "the air purifier operates quietly, the night light is on, and white noise lulls your baby to sleep." The white noise adds sound of its own, so this is a comfort feature, not a quieter fan setting. Our nursery air purifier guide covers this choice in more detail.
Keeping a Levoit quiet
Levoit's manuals give the same advice across models. Take the new filter out of its plastic packaging. Leave 15 inches of clearance, on all sides for the round Core and Sprout models, or in front for the Vital models. Clean the pre-filter, because Levoit says hair and lint can clog it and block airflow. The Core, Vital, Eleva, EverestAir and Sprout manuals we searched list "Increased noise when the air purifier is on" as a sign that the filter may need replacing.
Three models give two figures in Levoit's own documents. The Core 300S-P page says 22-50dB and its manual 22-54.5dB. The Core 400S-P spec table says 22-52dB, but the summary on the same page and the manual say 24dB at the low end. The EverestAir-P page says 24-56dB and its manual 24-55dB. We list both figures and do not give any of these three a "quietest" award on the lower one. Several manuals also give a rated power that differs from the product page, which suggests the pages and manuals were not updated together.
How Levoit compares
This page ranks Levoit models only against each other. For how they sit among other brands, on each maker's own published figures, see our guide to the quietest air purifiers. Since Levoit, like most makers, states no measuring distance or standard, read our explainer on why decibel ratings rarely compare across brands before treating a gap of a decibel or two as real. For a brand that names both ends of most of its ranges, a figure on low and one on high fan speed, see our Blueair air purifier decibels page. Alen goes a step further and prints the airflow at every speed beside its two labelled figures; our Alen air purifier decibels page lists all five of its current models.
How we chose
We read Levoit's US air purifier collection and opened the product page and user manual for every model. We recorded each noise figure in Levoit's words, with the setting Levoit ties it to where it names one, and noted where a page and its manual disagree. We sorted the low figures into Sleep Mode, lowest fan speed and unlabelled groups, and ranked top figures only within a room-size group, using Levoit's own room size at 4.8 air changes an hour. Prices are Levoit's US list prices on October 3, 2026.
We did not measure any of these purifiers. Every figure here is Levoit's own, from its product pages and manuals, and Levoit states no measuring distance or test standard for any of them. Owners' rooms, floors and filters will change what they hear.
