Search for Lasko fan decibels and the answer is, more often than not, on Lasko's own page. Lasko puts two rows in the specification table of many of its fans, "Noise dB-Low" and "Noise dB-High", both in dBa, and repeats the low figure in its feature text with phrases such as "as low as 24 dBA on low". That is more than most fan brands publish. It is also uneven: half the range has no figure, and a handful of pages print 0 dBa where a number should be.
This guide lists every current US Lasko tower, pedestal and table fan with a published figure, ranked quietest first within its own type and only against figures at the same speed. On October 4, 2026, we counted 58 Lasko-branded tower, pedestal, table, box and floor fan pages on lasko.com, and 29 of them carried a usable figure. We do not rank Lasko against other brands here; for how it compares, see our quietest tower fans guide.
Our picks are listed above, with full specifications for each.
Every figure on this page comes from lasko.com. Most come from the specification table, where a Lasko fan with a figure gets two rows: "Noise dB-Low", the figure at the lowest speed, and "Noise dB-High", the figure at the highest. Both use the unit "dBa". The feature text on the same page usually repeats the low figure in looser words: "as low as 23 dBA on low speed" for the EcoQuiet pedestal, "as quiet as 31.5 decibels on its lowest setting" for the Smart tower, "as low as 24 dB" for the Pinnacle. One fan, the 48" tower, has no table row at all and gives its figure only in the text.
Lasko never states a measuring distance, a room or a test standard, and its help center is candid about why: "At this time, Lasko manufactures units for residential use only so sound testing is not a requirement." So these are maker figures with no method attached. We quote each one as Lasko writes it, rank low figures only against low figures and high only against high, and keep each fan type in its own list. Our explainer on why decibel ratings rarely compare across brands covers why that caution matters even inside one brand.
We checked the user manuals Lasko links from each page as well. None of them gives a decibel figure. The DC tower manuals do carry one useful line on noise: "A very dirty or clogged filter will result in a decrease in air performance and an increase in noise level of your fan."
Lasko listed 22 indoor tower fans on October 4, 2026, not counting the Rise pedestal towers, which we group with the pedestals below. Fifteen have both a low row and a figure we can rank on. Ties are listed cheapest first.

On the high end, the order changes: the EcoQuiet 42" DC at 46 dBa, the 40" Smart at 48.7, the SlimForce at 51, the Ascend 36" and Apex at 52, the Pinnacle at 54, the Ascend DC at 54.5, the Wind Curves at 55.4 and the High Velocity at 56.35.
Two more towers have a figure we cannot rank. The 48" tower (T48312, T48314, $99.99, white in stock) has no table row; its text says Nighttime mode lowers the speed "with a low-speed noise rating of only 38.6 decibels", a figure given only in the text and written in decibels rather than dBa, so we keep it out of the ranking. The 36" tower (2510, 2511, $79.99) lists only "Noise dB-High 54.5 dBa", with no low row.
No figure at all: the 32" towers (T32202 and T32200), the 36" 3-speed (T36205), the 36" 4-speed with Dark Mode (T36511) and the 38" Hybrid (T38415).
Pedestal and pedestal tower fans
Lasko sells two kinds of fan on a stand: bladed pedestal fans with a round head, and tall pedestal towers, the Rise and Elevation, that look like a tower fan on a pole. We keep them apart.
Pedestal fans, lowest low figure first.
- EcoQuiet 18" DC (S18708, S18705): 23 dBa low, 61 dBa high. $89.99, black in stock.
- Whirlwind 7" DC (APDC301, APDC302): 25 dBa low, 50 dBa high. $99.99, white in stock.
- 16" with thermostat (S16612, S16614): 41.1 dBa low, 53 dBa high. $59.99, black in stock. Lasko names its four speeds Whisper Cool, Gentle Breeze, Light Wind and Wind Chill.
On high, the order flips: the Whirlwind 7" DC at 50 dBa, the 16" at 53 and the EcoQuiet at 61. No figure: the 16" 3-speed pedestals (S16500 and model 2527 listings), the 18" Elite (S18612), the 20" pedestal (S20620 and S20620M) and the Cyclone 18" (S18355), all sold out.
Pedestal tower fans. All three list 24 dBa on low. The Rise 54" DC (RTF105, $79.99, sold out) lists 52 dBa on high. The Elevation 54" DC (EST100, $99.99, in stock) reads 0 dBa on high. The Rise 54" AC (RTF100, sold out, $49.99 on sale) repeats the DC model's 24 and 52 on a page whose title says 4 speeds and whose table says 8, so we do not rank it. Our pedestal fan guide sets the EcoQuiet and Whirlwind beside other brands' labeled figures.
- Pinnacle 15" DC (DST016, DST015): 24 dBa low, no high row. $69.99, sold out.
- StealthBreeze 15" DC (TDC145, TDC142): 24 dBa low, no high row. $69.99, sold out.
- Whirlwind 7" DC (A12667, A12668): 26 dBa low, 57.6 dBa high. $69.99, sold out.
- Whirlwind 7" (A12557, A12558): 35.5 dBa low, 52.2 dBa high. $39.99 on sale, in stock.
- 12" Classic Metal (R12210): 37.9 dBa low, 53.6 dBa high. $59.99 on sale, sold out. Its text says "3 quiet speeds as low as 37.9 decibels".
- Whirlwind Tilt 12" (A12105, A12107): 39 dBa low, 55 dBa high. $34.99, sold out.
On high: the Whirlwind 7" at 52.2 dBa, the Classic Metal at 53.6, the Whirlwind Tilt at 55 and the Whirlwind 7" DC at 57.6. The plain 12" table fan (2017, 2012, $39.99) lists only "Noise dB-High 0 dBa". No figure: the 16" table fan, the 6" personal fan, the Breeze Machine, the Wind Tower 14", the MyCool mini blower and the SlumberBreeze, whose page sells "2 quiet fan speeds with 5 distinct white noise profiles" without a decibel figure for either. Our desk fan guide compares Lasko's table fans with other makers'.
Lasko sold three 20" box fans on October 4, 2026: the Cool Colors ($34.99), the Power Plus ($39.99) and the Pro Power ($49.99). None has a usable figure. The Pro Power's table reads "0 dBa" for both low and high; the other two have no noise row, and the Power Plus describes its speeds only as running "from whisper quiet to a powerful high setting". For box fans whose makers do publish a figure, see our quietest box fans guide.
Lasko's floor fans, its 10" and 20" air circulators, the Wind Machine, Wind Tunnel and Cyclone 20", and its two 20" High Velocity Floor Fans, carry no figure either. One High Velocity page (2264QM) prints "0 dBa" on high.
Lasko fans outside these five types
Lasko also prints figures for fans that do not belong in a bedroom list, and we keep them out of the rankings above. Its outdoor towers list 45.0 dBa low and 59.4 dBa high for the 42" Outdoor and the Misto 42" misting tower, and 50.4 and 62.2 for the 49" Outdoor. Its utility blowers list 52.3 to 63.4 dBa on low, apart from the 14" DC Air Mover at 24 dBa low and 57 dBa high. The DUO Comfort 38" fan and heater lists 34.9 dBa low and 55.4 dBa high.
What Lasko says makes its fans quiet
Lasko's quiet claims hang on two names. EcoQuiet is the older one: the 42" tower's brushless motor is "designed to use over 60% less energy than comparable AC tower fans" and stays "noticeably quiet even on higher speeds". WhisperForce is the newer one, on the Pinnacle tower and table fans, the StealthBreeze, Ascend DC, Stratus, Elevation, Rise, the EcoQuiet and Whirlwind DC pedestals and the TDC towers, described on the 36" DC page as a motor that "runs as low as 24 dBA on low while using less energy than a comparable AC motor tower fan".
The figures mostly bear out the low end. Among towers, every DC model lists 23 to 26 dBa on low except the high velocity Stratus DC at 30, against 29 to 39 for towers without a DC claim. Among pedestals it is 23 and 25 against 41.1, and among table fans 24 and 26 against 35.5 to 39. The energy rows explain it. The EcoQuiet tower lists 2.9 W at the bottom of its range, the Ascend 36" without DC 33 W.
The high end is a different story. More speeds mean a higher ceiling as well as a lower floor, and the EcoQuiet pedestal tops out at 61 dBa, the Whirlwind 7" DC table fan at 57.6, both above their AC siblings. Only the EcoQuiet tower combines the lowest low with the lowest high in its type.
What the numbers mean in a room
Decibels are logarithmic, and roughly every 10 dBa sounds twice as loud. By Lasko's own figures, the Wind Curve on low at 39 dBa would sound about twice as loud as the Ascend 36" on low at 29, and the EcoQuiet pedestal on high at 61 about twice as loud as the Whirlwind 7" DC pedestal on high at 50. Gaps of one or two decibels, such as 23 against 24, are too small to choose on when Lasko gives no distance. Our decibel chart puts these figures beside a whisper and a quiet library, and dBA explained covers the weighting behind the unit.
The low figure describes a speed you may not use on a hot night. A DC fan with 12 or 24 speeds gives you more room between its quietest and loudest settings, and a Night or Sleep mode that steps the speed down does more for sleep than a headline figure. Our guide to the quietest fan for sleeping compares those modes across brands.
Where Lasko's pages disagree with themselves
- Placeholders. "0 dBa" on the Pro Power box fan (both rows), the Elevation 54", the 36" DC and 40" DC towers, the 12" table fan and a High Velocity Floor Fan, and a stray minus two on the 48" DC tower.
- Rise 54" AC. A 4-speed AC title over a table that lists 8 speeds and a feature line about WhisperForce DC Technology, with figures identical to the Rise DC.
- Apex 42". "90-degree wide-angle oscillation" in the text, 87 degrees in the table.
- 36" DC tower. Its linked manual is the Ascend 36" DC's manual.
Stock and price on the day we checked
We checked every price on lasko.com on October 4, 2026. Many of Lasko's quietest fans on paper were sold out that day: the Ascend DC, the 36", 40", 42" and 48" DC towers, the Stratus DC, both 15" DC table fans, the Whirlwind 7" DC table fan and the Rise DC. In stock with a figure were the EcoQuiet tower and pedestal, the Pinnacle, the Ascend 36", Apex, Smart, High Velocity and Wind Curve towers, the Whirlwind 7" DC pedestal, the 16" pedestal, the Elevation and the Whirlwind 7" table fan. For how Lasko's figures look beside other brands' published numbers, see our Vornado fan decibels guide and Dreo fan decibels guide.
How we chose
We read Lasko's US product listing and opened the page for every Lasko-branded fan, 74 pages in all, including outdoor fans, blowers, wall mount and window fans and fan heaters that we then set aside. For each page we recorded the Noise dB-Low and Noise dB-High rows exactly as printed, any sentence that mentioned decibels, the price and the stock status, and we searched every linked user manual for a noise figure. We grouped fans by Lasko's own types, ranked low figures against low figures and high against high, set placeholders aside, and gave no ranking to a page that contradicts itself.
We did not measure any of these fans. Every figure here is Lasko's own, quoted from lasko.com in Lasko's own words and unit, and Lasko states no measuring distance and no test standard for any of them.
