Dyson Pure Hot + Cool HP04 FanThe bladeless Dyson Pure Hot + Cold is a remote-controlled heater, fan and air purifier all in one, according to the brand.

It also includes a nighttime mode that uses a dimmed display, according to Dyson. Wiseman noted this space heater is “substantially quieter” than many other models and can regulate indoor air quality: using a HEPA-style filter, it can capture 99.97 percent of particles that are 0.3 microns in size, says the brand. The unit can also connect to Wi-Fi so you can control your machine remotely and schedule when your air purifier is on, using the Dyson Link app.

Top ceramic combination space heater: Lasko

Lasko Oscillating Ceramic Heater

What we like

  • Automatically shuts off
  • Cost-effective
  • Quiet operation

The most affordable option on this list, the portable Lasko Oscillating Ceramic Heater can be a worthwhile option if you’re on a budget. Lasko says this space heater can heat rooms up to 300 square feet and offers two heat levels — low heat and high heat — along with a cool air fan setting. You can also use the thermostat knob to both turn on the unit and have it shut off automatically once a certain temperature has been reached (though the knob itself doesn’t list actual numbers), according to the brand.

How to shop for a space heater

The first step when shopping for a space heater is determining the size of the area you plan to warm. Van Tuijl generally recommends buying a space heater that is in the 500-1000 watts range for smaller rooms (which are typically considered 120 square feet or less), and between 1,000 and 1,500 watts for larger rooms.

As a general rule of thumb, according to indoor air-quality company Sylvane, you need roughly 10 watts of heating power for every square foot of floor area in the room. This means that a 1,500-watt space heater can be the primary heat source for an area measuring up to 150 square feet. Carson also says it’s important to make sure your heater is compatible with your space: “If you’re shopping for an indoor space heater, stay away from gas and propane models. If you need a heater for your patio, a gas model may be a good option as long as it’s the correct size. Do a lot of research and read the manufacturer’s guidelines.” Some other key features to look out for while shopping include:

  • Noise level. Some units are louder than others. If you’re shopping for a bedroom or home office, that’s something to keep in mind. One resource for finding devices that are especially quiet is Quiet Mark, which tests and awards products based on their noise output.
  • Safety features. Space heaters can be potential fire hazards, so don’t overlook any built-in features designed to lessen that chance. “Make sure to buy one that has protective grills as well as auto-shut off capabilities [in case] the heater tips over or overheats,” said Carson. If you’ve had your space heater for a while, she recommended double-checking for an auto-shut off feature since some older models may not have one.
  • Warranty. Don’t forget to look into warranty options. “This way, you can protect your investment in case anything happens,” Wiseman noted. A quality space heater will have a three-year warranty. 
  • Energy efficiency. Space heaters are generally more energy efficient than central heating since you’re only heating up the room and some space heaters are also more energy efficient than others. Since space heaters don’t have Energy Star ratings — which independently certifies a product’s energy efficiency — the easiest way to determine if your unit conserves energy is by checking whether it has features like an adjustable thermostat and auto shut-off option that can maintain a certain temperature and prevent a room from overheating, according to the Department of Energy.
