10 Best Heaters 2026 in the United States

The Dyson Purifier Hot+Cool HP2 De-NOx combines efficient heating with advanced air purification. It heats a room evenly using Dyson's powerful Air Multiplier technology, suitable for spaces up to about 109 square feet. The heater provides smooth airflow and includes a thermostat for temperature control.

Its unique strength lies in top-tier HEPA H13 filtration that removes 99.97% of tiny particles, along with capturing nitrogen dioxide and formaldehyde, which is rare in typical heaters. Safety is well addressed with certifications like CARB and EPA, plus a sealed filter system that prevents contaminants from escaping. The unit operates quietly compared to many heaters, making it comfortable for indoor use.

Portability is decent—it weighs about 12 pounds with a slim, tall design and includes a magnetic remote that stores on the device. This heater is on the pricier side and requires some assembly. Its focus on air purification means it’s bulkier and more complex than a simple heater. This product suits someone looking not just for warmth but also cleaner air year-round, especially in urban or polluted environments. Those primarily seeking an affordable, straightforward heater might find it more than needed, but if air quality is important alongside heating, it’s a strong choice.

The Dreo Space Heater is a portable electric heater designed for indoor use, perfect for keeping spaces like bedrooms, offices, and living rooms warm. One of its main strengths is its powerful 1500W PTC heating system, which can quickly deliver warmth and reach areas up to 200 square feet, making it ideal for medium-sized rooms. The heater features a digital thermostat that allows users to set temperatures from 41°F to 95°F in precise 1°F increments, promoting energy efficiency while providing comfort.

Safety is a significant focus with the Dreo heater, as it includes essential features like an innovative tip-over protection and overheat protection, alongside flame-retardant materials. This makes it a reliable choice for households with children or pets. Users also appreciate the quiet operation, with a noise level of only 34dB, ensuring that it won't disrupt your peace while it warms the room.

On the convenience side, the unit comes with a remote control and a 12-hour timer, making it easy to operate from a distance. The compact design and built-in handle enhance portability, allowing you to move it effortlessly between rooms. However, there are some drawbacks. The heater’s coverage is limited to 200 square feet, meaning it may not be sufficient for larger spaces. While it has multiple modes, including an ECO setting, some users might find the energy efficiency still lacking compared to other options on the market. The reliance on electric power can also be a concern for those looking for more sustainable heating solutions.

The Mr. Heater Big Maxx MHU80NG is a powerful natural gas heater designed for large indoor spaces like garages or home workshops, covering up to around 2,600 square feet. Its strong heating capacity of 80,000 BTU allows it to warm big areas effectively. It includes an electronic thermostat for better temperature control, adding convenience and helping maintain a steady warmth. Safety features include spark ignition and a self-diagnostic control module, with a requirement for proper clearance to ensure safe operation.

This vented heater requires installation that allows for either vertical or horizontal exhaust, making it well suited for spaces where such venting is possible. Weighing over 78 pounds and mounting to the ceiling, it saves floor space but is not intended to be a portable option. The unit operates on natural gas, which can be more cost-effective than electric heaters for large areas, and it comes with a 3-year limited warranty on parts and a 10-year warranty on the heat exchanger, reflecting its durability.

Accessories such as the thermostat, hose, and regulator are not included, so additional purchases and installation effort will be necessary. This heater is ideal for those needing robust, permanent heating solutions in large indoor spaces with proper venting setups, rather than for casual or portable heating needs.
