There is no source-supported overall winner among these Lasko heaters: the documented models trade compact size for wider heat sweep, bladeless form, or added controls. Choose by the features that fit your room and routine—not by an unverified claim of superior heating. The comparison below covers seven ceramic models listed by Lasko; check the exact model variant, current availability, and its manual before buying.
How to choose a Lasko heater
Start with the space and the way you want heat distributed. A shorter tower may suit a tighter footprint; a model with adjustable sweep can direct warmth across more of the room; remote controls, timers, and thermostats affect convenience rather than proving better heating performance. Decide which features matter, then confirm that the exact listing and manual match.
- Compact size: CT14101 is listed at 14 inches and CT16670 at 16 inches.
- Wider heat sweep: CT22360 offers sweep settings from 90° to 360°.
- Bladeless design: AW310 and CW100 are bladeless tower models.
- Additional controls or protections: CT18950 lists a tip-over sensor and child lock; CT22498 lists a rollover design and child lock.
Manufacturer descriptions such as “large room,” coverage area, energy savings, and quiet operation are product-page claims, not independent performance measurements. The available information does not establish comparative heating results, operating costs, durability, or room-by-room outcomes.

Which model may fit your priorities?
For a compact footprint
The 14-inch CT14101 is the shortest listed option in this group. It has two heat settings, oscillation, and an Auto Eco thermostat. The 16-inch CT16670 is another compact tower and adds a remote and 8-hour timer. Neither size alone establishes how well a heater will warm a particular room.

For heat directed across a wider area
The CT22360 is the model here with explicitly listed adjustable 90° to 360° sweep settings. Its remote and thermostat add control options. A wider sweep is a design feature, not proof of greater heat output or room coverage.
For a bladeless tower format
Both AW310 and CW100 use a bladeless design and oscillate. The AW310 lists two heat settings, thermostat, timer, and an easy-vacuum filter. The CW100 lists a digital display and an 8-hour timer; its Lasko page states maximum coverage of 150 sq. ft. Treat that area as the manufacturer’s claim, not an independently verified result.

For a listed tip-over feature or child lock
CT18950 lists a tip-over sensor and child lock. CT22498 lists a rollover design and child lock. These are different product-page descriptions; do not assume other models include either feature, or that any listed safeguard makes a heater risk-free. Check the manual for operation and placement requirements.
For more settings and scheduled shutoff
CT22498 lists three heat settings, an adjustable thermostat, Auto Eco Mode, and a 12-hour timer. CT18950 also has three heat settings, plus two fan settings, 120° oscillation, and Auto Eco Mode. The CT16670 and CW100 list 8-hour timers. Compare the controls you will actually use rather than assuming more settings produce better heating.

Use a portable heater safely
The U.S. Consumer Product Safety Commission advises: “Keep portable heaters at least three feet away from drapes, furniture, bedding and other combustible materials.” It also recommends plugging electric heaters directly into a wall outlet—not an extension cord or power strip—and turning heaters off while sleeping. Follow the instructions for the exact model as well.
CPSC estimates an average of 1,600 portable-heater fires, 70 deaths, and 150 injuries per year for 2020–2022. These are agency estimates across portable heaters, including electric space heaters; they are not current-year counts or Lasko-specific incidents. CPSC also cautions that people who may be less able to respond to elevated ambient temperatures can be at risk of hyperthermia.
