The Lasko 6435 is slightly larger in between, but both are guaranteed to fit and look stylish in any room they are set up in. , but their designs are not bulky or oversized like some similar products.

Wattage is important to look at in a heater, because no matter how good-looking a heater is, if it doesn’t have the wattage to back it up, it won’t work. Both operate with a power of 1500 watts. They also both have high and low thermostat settings. However, the words high and low are just relative, so it’s important to know what they mean. Customers of both heaters reported that the lowest possible temperature was 60 degrees Fahrenheit (about 15 degrees Celsius) and the highest was 85 degrees Fahrenheit (almost 30 degrees Celsius). The temperature can change in five degree increments.

They are both fans listed on ETL as well. This means that the power they provide meets certain safety standards and that there are features that go above and beyond to provide that. For the Lasko 6405 and Lasko 6435, this comes in the form of an automatic timer that prevents the system from overheating. For these systems, this timer is seven hours, which is more than enough to regulate the temperature but also to prevent customers from the risk of fire.

There are, of course, a few shortcomings in what customers expect from their heaters. For the Lasko 6405, these were mostly complaints that the knobs are extremely loud when changing settings.

The Lasko 6405 and Lasko 6435 both come with a remote control to change heat, oscillation and wattage settings from across the room. Unfortunately, many customers who have actually used the remote have found that this is not a feature they want or use very often. Although I can see how a remote control can be very practical. Maybe when you want to turn off the heating when watching a movie.

Convenient Features

These two radiators offer the possibility of oscillation to the customer. It just means that the radiator will rotate to better cover the room evenly. The usefulness of this convenient feature depends on the customer and the room in which it is used.

Another practical feature is the progressive temperature control. Rather than having simple low, medium, and high set temperatures, these fans use a stepped system allowing users to change settings five degrees ranging from 65 to 80 degrees Fahrenheit.


These two fans and all other Lasko fans are backed by a three-year warranty. As long as you have proof of purchase – such as a receipt – your heater will be protected if it malfunctions or if there has been a manufacturing error.
