Comparison · Lasko towers
Three towers, one brand, and a trade-off you cannot buy your way out of: safety hardware or a safety listing, but not both.
How this page is funded: we earn a commission if you buy through the links here, at no extra cost to you. Picks are chosen before links are attached, which is why every roundup names something to skip. Full disclosure.
All three are 1,500 W ceramic towers with oscillation, a thermostat and a remote. The 755320 is the pick: ETL listed, a 3-year warranty, a published 900 W low setting, a checkable 150 sq ft claim and an 8-hour timer. Choose the Ellipse CT18950 instead only if you need the published child lock.
Lasko's tower line is easy to confuse: the model numbers are adjacent, the photographs are nearly identical, and all three are 1,500 W ceramic units that oscillate. Here is every published difference we could verify.
| 755320 (23 in) | 751320 (22.5 in) | Ellipse CT18950 (18 in) | |
|---|---|---|---|
| Published low setting | 900 W | 900 W | No — 3 modes, no wattages |
| Coverage claim | 150 sq ft | 150 sq ft | None published |
| Thermostat | Adjustable, digital display | Adjustable | Thermostat + digital display |
| Timer | 8 hours | 7 hours | Yes, length not published |
| Remote | Yes, with onboard storage | Yes | Yes |
| Safety listing | ETL, on Lasko's page | ETL, on Lasko's page | None named |
| Tip-over switch | Not published | Not published | Published |
| Child lock | Not published | Not published | Published |
| Warranty | 3 years | 3 years | None published |
| Maker's page reachable | Yes | Yes | No — listing only |
From Lasko's own product pages where reachable, otherwise from the retail listing — noted per row. All three are 1,500 W at 120 V, which is about 5,118 BTU/h and about 27.5 cents an hour.
Read the bottom four rows together and the problem is obvious. The two units with an ETL mark and a three-year warranty publish no tip-over switch. The unit that publishes a tip-over switch and a child lock publishes neither a mark nor a warranty, and Lasko's own page for it could not be reached at all. You cannot buy your way out of that inside this product line.
On everything that can be computed, it is the strongest of the three. The 900 W low setting is published, which means the economical mode costs a knowable 16.5 cents an hour and draws 7.5 A instead of 12.5 — enough to share a circuit. The coverage claim is 150 sq ft, and 1,500 W at 10 W per square foot is 150 sq ft, so the claim and our own arithmetic agree exactly rather than the maker's figure being about 1.7 times ours, as several in this category are.
It also has the 8-hour timer against the 751320's 7, and onboard storage for the remote. That last detail sounds trivial until the remote has been missing for a week and the heater has been running on high the whole time.
Against the 751320 specifically, the 755320 wins on the timer and the digital display and loses on nothing. They publish the same wattages, the same coverage, the same ETL mark and the same warranty. If the 751320 is meaningfully cheaper on the day you look, take it — the difference is an hour of timer and a display. If the prices are close, there is no reason to choose it.
One reason, and it is a good one: it is the only tower in our registry that publishes both a tip-over switch and a child lock. On a tall, light, narrow object in a house with a small child, those are the two features that matter most, and no amount of ETL marking substitutes for hardware that stops the thing when it goes over. At 18 inches it also has a lower center of gravity than the 22.5- and 23-inch units.
For a nursery our criteria point at the CT18950 rather than the 755320, precisely because of the child lock — see the nursery roundup for the full set. For a bedroom, an office or a living room with no small children, the missing disclosure on the CT18950 is the bigger risk and the 755320 is the better buy. The safest picks, feature by feature.
None of them publishes a thermostat set-point in degrees. All three say "adjustable", which on a Lasko means a dial or a digital display with no stated range — you can see the room temperature on two of them but you are not choosing 64°F. Across the 29 purchasable heaters we track, only 7 publish a range, and none of Lasko's 4 do. That is the brand's single consistent weakness and it is the one that affects your bill, because hours are the only variable.
And none of them escapes the shape problem. A tower is tall, light and narrow, which is the geometry most likely to tip and the one most likely to be pulled over. A tower on a deep-pile rug is worse again — not because carpet ignites under a working heater, it does not, but because the rug makes tipping easier and then insulates whatever tipped.

A home office, family room or bedroom at or under 150 sq ft where you want a real thermostat and a timer without paying for a metal cabinet.
What it is not for
A nursery, or a room where a curious pet or toddler can reach it. No child lock and no published tip-over switch is the wrong combination at floor height.
2 · The cheapest tower whose claims check out
The 755320's shorter, simpler sibling: the same honest 150 sq ft claim and the same published 900 W low setting, with a 7-hour timer instead of an 8-hour one.

| Heat settings | Two |
| Thermostat | Adjustable |
| Oscillation | Yes |
| Timer | 7-hour auto-off |

Who it is for
A home office or adult bedroom at or under 150 sq ft where a thermostat, a timer and a remote matter more than a metal cabinet, and the heater can stand in clear floor space.
What it is not for
A nursery or a room with a dog or a toddler. No published tip-over switch and no child lock on a tall, light tower is the wrong combination at floor height.

3 · The only tower here with both cutoffs and a child lock
The short Ellipse tower is the one that publishes the two things the taller Laskos do not: a tip-over switch and a child lock, on top of a digital display and wide oscillation.
| Published specification | |
|---|---|
| Rated power | 1,500 W at 120 V |
| Heat modes | Three, plus two fan settings; the per-mode wattage is not published |
| Controls | Digital display, thermostat, remote, timer |
| Oscillation | Wide oscillation |
| Height | 18" |
| Safety | Tip-over switch and child lock, both published in the listing |
| Heat type | Ceramic (PTC) |
| Maker’s coverage claim | None published — the coverage figure above is ours |
| Safety listing | The listing publishes a tip-over switch and a child lock but names no UL or ETL mark. Lasko's own product page for this model could not be reached, so check the rating plate on the unit. |
Who it is for
A living room, family room or home office where children or animals move past the heater and a tip-over switch plus a child lock are worth more than an extra five inches of tower.
What it is not for
Anyone who needs to compute the cost of a low setting, or who wants the manufacturer's own specification sheet before buying — for this model it was not reachable.
No decibel figure for any of the three. All are ceramic fan heaters, so all are audible, and none of them publishes a number. If quiet is the binding requirement the answer is a fanless design rather than a quieter tower — the quietest picks, and why they are all fanless.
And no per-mode wattage for the CT18950, which is why its cost figures on this site are the 1,500 W maximum only. We have not estimated what its three modes draw, because an estimate presented in a table becomes a fact the moment someone quotes it.
Very little. Both are 1,500 W ceramic towers with a published 900 W low setting, a 150 sq ft coverage claim, an ETL mark and a 3-year warranty. The 755320 has an 8-hour timer, a digital display and onboard remote storage; the 751320 has a 7-hour timer and no display. Buy the cheaper one on the day unless you want the display.
The Ellipse CT18950 is the only tower in our registry that publishes both a child lock and a tip-over switch. The trade-off is that Lasko's own product page for it could not be reached, so it publishes no ETL mark, no warranty and no coverage figure.
Not consistently, and not on the two best-documented units. The 755320 and 751320 publish cool-touch housings and overheat protection but no tip-over switch; the Ellipse CT18950 publishes one. On a tall narrow heater that is a gap worth knowing about.
The 755320 and 751320 are, stated on Lasko's own product pages. The Ellipse CT18950 names no mark in its listing, which does not mean it is unlisted — only that it is not published where you can check it before buying.
About 27.5 cents an hour at 1,500 W, at our published rate of 18.34 cents per kWh — roughly $66 a month at eight hours a day. On the published 900 W setting of the 755320 or 751320 it is about 16.5 cents an hour.
The 755320, on the published specifications: a 900 W low setting you can cost, an 8-hour timer that covers a night and stops, and a thermostat with a display. It publishes no decibel figure though, and if silence matters more than features a fanless oil-filled radiator is the better shape.
Tall, narrow and light is the shape that falls over. Ranked on which makers publish a tip-over switch.
900-1,500 W, digital thermostat, 8-hour timer, ETL listed — and a 150 sq ft claim that matches the math exactly.
Lasko publishes wattage, coverage and ETL, and backs it 3 years. Vornado publishes none of those and backs it 5.
Sweeping spreads a fixed 1,500 W more evenly and more slowly. When that helps, and the one unit that sweeps vertically.
Tip-over, overheat, child lock, cool-touch, wall mounting — what each mechanism actually prevents.
Tip-over, overheat, cool-touch and child lock — four mechanisms, four different failures prevented.
