Lasko model comparisons
Lasko Halo CT22520 vs CT22850: fan-only and PowerGuard
These two Lasko heaters are close in size and broad purpose: both are 22-inch ceramic floor towers rated up to 1,500 watts, with three heat settings, an adjustable room-temperature control, a remote, base oscillation and a 12-hour shutoff countdown. The more useful choice is not which one has a larger number on its product page. It is whether you need the Halo CT22520’s distinct fan-only and outlet-monitoring features—and whether your room can follow the same strict floor, clearance and outlet plan.
Choose the Halo CT22520 for fan-only and PowerGuard
The Halo CT22520 documents two fan-only speeds (F1 and F2), separate from Low, Medium and High heat. This makes it the better documented fit if a fan-only setting is an essential need. The similarly sized CT22850’s reviewed manual and page do not document a fan-only mode, so do not infer one from the presence of a fan that distributes heat.
CT22520 also includes PowerGuard, an outlet-voltage monitor that can shut the heater off and alert if it detects an unsafe outlet condition. It is not active by default: the current manual says to enable it manually and confirm the icon. That is a setup task, not permission to use an extension cord or questionable receptacle. The CT22850 material reviewed here does not establish PowerGuard. An essential PowerGuard requirement therefore favors the Halo; unknown is not an equivalent feature.
The CT22520’s remote uses two AAA batteries, not included. Its child lock prevents most control changes, but Power remains available and currently running functions remain on. The manual does not describe a named Sleep Mode sequence, although it does provide display and beep controls. A user who needs a power-blocking lock or an exact Sleep routine should not treat the word “nighttime” in marketing as proof.
CT22850 is the more straightforward heater-only tower
If your request is simply adjustable supplemental heat with three stages, Auto Eco control, a remote and a countdown, the CT22850 already covers those needs. Its reviewed manual describes automatic heat control and a 12-hour off timer, but not a later scheduled start. Its current page lists a maximum output of 1,500 watts and up to 300 square feet; those figures do not establish a guaranteed room-heating result.
CT22520’s product page also lists up to 300 square feet and 900–1,500 watts, but neither model publishes a wattage for each individual heat level in the reviewed sources. Neither should be selected because you expect a known low-setting draw or a measured area outcome. Both require a direct 120-volt wall receptacle; the manuals prohibit extension cords and power strips, tell users not to share the circuit, and say not to leave the heater operating unattended.
Similar bodies do not mean identical movement evidence
The official dimensions are nearly identical: CT22520 is listed at 21.63 inches high and 7.1 by 7.9 inches across; CT22850 is listed at 21.6 by 7.1 by 7.9 inches. For either tower, these small body measurements do not shrink the operating zone: Lasko’s manuals require 36 inches of front clearance and 12 inches at the sides and rear from combustibles, on a stable level floor.
Both are described as oscillating. The CT22850 manual specifies horizontal movement; the CT22520 manual confirms base oscillation but does not name the axis or a sweep angle. Do not use a heat-distribution phrase as a mechanical-angle specification. Neither product’s maker claim is an independent room test.
Pick by the actual routine, not by near-identical styling
Choose the Halo if fan-only air movement or manually enabled PowerGuard changes your decision, and if you can provide its supervised dry-room floor placement. Choose CT22850 when those distinctions are not essential and you want its documented tower-heating controls. For a shorter floor tower with fan-only, compare the 18-inch CT18950/CT18951; for an actual tabletop plan, compare the separate CD12950/CD12951 instead.
Neither 22-inch model documents app control, a later start or unattended operation. If any of those is essential, require exact-model proof and look elsewhere. Read the exact instructions before buying; availability can change, and this comparison does not claim personal testing.
