10 Best Space Heaters

The Dyson Purifier Hot+Cool HP1 is a versatile space heater designed for rooms up to around 27 square meters, making it suitable for small to medium-sized living spaces. It stands out by combining powerful heating with air purification, using a fully sealed HEPA H13 filter system that captures 99.95% of tiny allergens and pollutants, which is excellent if you’re concerned about air quality. The heater uses Dyson’s Air Multiplier technology, which delivers smooth airflow to heat a room evenly or cool you down during warmer months, adding year-round value.

In terms of energy use, it operates at 40 watts, which is generally efficient for a device with combined heating and cooling functions. Safety is well covered with an auto shutoff feature, giving peace of mind if the heater is accidentally tipped or left on too long. Noise-wise, it runs at about 63 decibels, which is roughly the sound level of a normal conversation—noticeable but unlikely to be disruptive.

Portability is decent given its height (76.5 cm) and weight (5.26 kg); it’s not the lightest heater but still manageable to move around as needed. Controls are user-friendly, with a curved magnetic remote that docks neatly on the unit and smart app connectivity, allowing you to monitor and adjust settings remotely or via voice commands if you have compatible devices. While the heating capacity is relatively limited compared to larger heaters, making it less ideal for bigger rooms or very cold environments, the combination of air purification and smart features makes the Dyson HP1 a strong contender for those wanting flexible, multi-functional climate control. For straightforward, powerful heating in large spaces, other options might be more suitable.
